Sorin chose a three-digit number and doubled it. Jiao chose a two-digit number. Carlos subtracted Jiao’s number from Sorin’s product. What is the greatest number Carlos can get?
HELP QUICK PLS
Answer:
The number is 1988.Step-by-step explanation:
Carlo's outcome will be the greatest if Sorin's number will be the highest and Jiao's number is the lowest.
Sorin choose a three digit number, the highest three digit number is 999.
After doubled the number, 999, the outcome will be 1998.
Jiao chooses two-digit number, the lowest two-digit number is 10.
Hence, the greatest number that Carlo can get is (1998 - 10) = 1988.
Final answer:
The greatest number Carlos can get is 1988, which is found by doubling the largest three-digit number, 999, to get 1998, and then subtracting the smallest two-digit number, 10.
Explanation:
To find the greatest number Carlos can get, we must consider the largest possible three-digit number that Sorin could double and the smallest possible two-digit number Jiao could choose.
The largest three-digit number is 999. When doubled, it becomes 1998. The smallest two-digit number is 10. Therefore, Carlos' greatest possible number is obtained by subtracting the smallest two-digit number from Sorin's doubled number:
1998 - 10 = 1988
Hence, the greatest number Carlos can get is 1988.

Answer:
a. 1/10
b. 4/10
c. 20
Step-by-step explanation:
There are 10 equal sections.
a. 1 section is labeled "Large Prize", so the probability of winning a large prize is 1/10.
b. 1 section is labeled "Large Prize" and 3 sections are labeled "Small Prize", so there's 4 prize section. Therefore, the probability of winning a prize is 4/10.
c. Each person has a 4/10 chance of winning a prize. So if there are 50 people, we would expect 4/10 × 50 = 20 people to win a prize.

Match each transformation or sequence of transformations to an equivalent transformation or sequence of transformations.
a 90° counterclockwise rotation about the origin
a 180° rotation about the origin
a 90° clockwise rotation about the origin
Answer:
a 90° clockwise rotation about the origin
a 180° rotation about the origin
a 90° counterclockwise rotation about the origin
Step-by-step explanation:
Transformations are done on a Cartesian Plane, which is the grid with four quadrants. (See picture) Each quadrant is 90°, so two quadrants is 180°.
When you rotate counterclockwise it is like in the picture. When you want to rotate clockwise, it's the other way.
When we rotate 180°, it does not matter if it is counterclockwise or clockwise because the result is the same (both move two quadrants).
We can imagine an example to help us solve the problem. Let's say we are rotating an object starting in first quadrant. (Upper right quadrant).
Find out which quadrant the object ends up with each instruction:
FROM THE PICTURE:
"a 90° counterclockwise rotation about the origin (Q2) and then a 180° rotation about the origin"
End: Quadrant 4
"a reflection across the x-axis (Q4) and then a reflection across the y-axis"
End: Quadrant 3
"a 90° clockwise rotation about the origin (Q4) and then a rotation 180° about the origin"
End: Quadrant 2
FROM YOUR LIST:
"a 90° counterclockwise rotation about the origin " Quadrant 2
"a 180° rotation about the origin " Quadrant 3
"a 90° clockwise rotation about the origin" Quadrant 4
Match each ending quadrant from your list with the same ending quadrant from the picture.
The order that you should put your list into the boxes is:
a 90° clockwise rotation about the origin
a 180° rotation about the origin
a 90° counterclockwise rotation about the origin

In trapezoid PQRS, PQ is parallel to RS. Let X be the intersection of diagonals PR and QS. The area of triangle PQX is 20 and the area of triangle RSX is 45. Find the area of trapezoid PQRS.
Answer:
The area of trapezoid PQRS is 125 square units
Step-by-step explanation:
The picture of the question in the attached figure
we know that
If trapezoid PQRS with parallel sides PQ and RS is divided into four triangles by its diagonals PR and QS , intersecting at X, then the area of triangle PSX is equal to that of triangle QRX, and the product of the areas of triangle PSX and triangle QRX is equal to that of triangle PQX and triangle RSX
Let
A_1 ----> the area of triangle PSX
A_2----> the area of triangle QRX
A_3 ---> the area of triangle PQX
A_4 ---> the area of triangle RSX
[tex]A_1*A_2=A_3*A_4[/tex]
[tex]A_1=A_2[/tex]
so
[tex]A_1^2=A_3*A_4[/tex]
we have
[tex]A_3=20\ units^2\\A_4=45\ units^2[/tex]
substitute
[tex]A_1^2=(20)(45)\\A_1^2=900\\A_1=30\ units^2[/tex]
The area of trapezoid is equal to
[tex]A=A_1+A_2+A_3+A_4[/tex]
substitute
[tex]A=30+30+20+45=125\ units^2[/tex]
Final answer:
The area of trapezoid PQRS is found by adding the areas of triangle PQX (20 square units) and triangle RSX (45 square units) together, which equals 65 square units.
Explanation:
The area of trapezoid PQRS can be found by summing up the areas of triangle PQX and triangle RSX. Since diagonals PR and QS intersect at point X, both triangles share the same height, which is the perpendicular distance from point X to the bases PQ and RS. Thus, the area of trapezoid PQRS is simply the sum of the areas of the two triangles.
To calculate the area of trapezoid PQRS, we add the area of triangle PQX, which is given as 20, to the area of triangle RSX, which is given as 45. Therefore, the area of trapezoid PQRS is:
Area of trapezoid PQRS = Area of triangle PQX + Area of triangle RSX = 20 + 45 = 65
So, the area of trapezoid PQRS is 65 square units.

Solve -2.5(4x - 4)=-6
Final answer:
To solve the equation -2.5(4x - 4) = -6, distribute -2.5 to the terms inside the parentheses, isolate the variable, and solve for x.
Explanation:
To solve the equation -2.5(4x - 4) = -6, we can start by distributing -2.5 to the terms inside the parentheses:
-10x + 10 = -6
Next, we can isolate the variable by subtracting 10 from both sides:
-10x = -16
Finally, we can solve for x by dividing both sides by -10:
x = -16/-10
Therefore, x = 1.6.
The sum of two numbers is 35. The greater
number is 1 less than 5 times the smaller number.
What are the two numbers
Answer:
x = 29
y = 6
Step-by-step explanation:
Let the two numbers be represented as x and y
x + y = 35
x = 5y - 1
Substitute x as 5y -1 in equation one
5y -1 + y = 35
5y + y -1 = 35
Add 1 to both sides
6y - 1 + 1 = 35 + 1
6y = 36
Divide both sides by 6
6y/6= 36/6
y = 6
Now substitute y as 6 in any of the equations to get x.
Using equation one ,
We have
x + y = 35
x +6 = 35
Subtract 6 from both sides
x + 6 - 6 = 35 - 6
x = 29

The solution set is x = 3, y = 4 (or) x = 3, y = –4.
Solution:
Given system of algebraic equations are
[tex]y^{2}+(x-8)^{2}=41[/tex] – – – – – (1)
[tex]y^{2}-25=-x^{2}[/tex] – – – – – (2)
Expand equation (1) using algebraic identity: [tex](a-b)^2=a^2-2ab+b^2[/tex]
[tex]y^{2}+x^2-16x+64=41[/tex]
subtract 64 from both sides of the equation
[tex]y^{2}+x^2-16x+64-64=41-64[/tex]
[tex]y^{2}+x^2-16x=-23[/tex] – – – – – (3)
Now, to arrange equation (2) in order, add [tex]x^2[/tex] on both sides.
[tex]y^{2}-25+x^2=-x^{2}+x^2[/tex]
[tex]y^{2}-25+x^2=0[/tex]
Add 25 on both sides of the equation,
[tex]y^{2}+x^2=25[/tex] – – – – – (4)
To solve this subtract equation (4) from equation (3)
[tex]\Rightarrow y^{2}+x^2-16x-(y^{2}+x^2)=-23-25[/tex]
[tex]\Rightarrow y^{2}+x^2-16x-y^{2}-x^2=-23-25[/tex]
[tex]\Rightarrow -16x=-48[/tex]
Divide both sides of the equation by –16,
⇒ x = 3
Substitute x = 3 in equation (4), we get
[tex]\Rightarrow y^{2}+3^2=25[/tex]
[tex]\Rightarrow y^{2}=25-9[/tex]
[tex]\Rightarrow y^{2}=16[/tex]
[tex]\Rightarrow y=\pm 4[/tex]
i. e. y = 4 (or) y = –4
The solution set is x = 3, y = 4 (or) x = 3, y = –4.
A tree casts a 12 foot shadow while the sun is at an angle of elevation of 58º. Use
this information to approximate the height of the tree to the nearest tenth of a foot.
The height of tree is 32 meter
Solution:
Given that, The sun is at an angle of elevation of 58 degree
A tree casts a shadow 20 meters long on the ground
The sun, tree and shadow forms a right angled triangle
The figure is attached below
ABC is a right angled triangle
AC is the height of tree
AB is the length of shadow
AB = 20 meters
Angle of elevation, angle B = 58 degree
By definition of tan,
[tex]tan \theta = \frac{opposite}{adjacent}[/tex]
In this right angled triangle ABC,
opposite = AC and adjacent = AB
Therefore,
[tex]tan\ 58 = \frac{AC}{AB}\\\\tan\ 58 = \frac{AC}{20}\\\\1.6 = \frac{AC}{20}\\\\AC = 1.6 \times 20\\\\AC = 32[/tex]
Thus height of tree is 32 meter

Given that,
Mrs.Rome has 2/3 of a pan of lasagna left after dinner
She wants to divide the leftover lasagna into 4 equal servings
2/3 is divided into 4 equal servings
Therefore,
[tex]1\ equal\ serving = \frac{\frac{2}{3}}{4}\\\\1\ equal\ serving = \frac{2}{12} = \frac{1}{6}[/tex]

A small bottle of Dr.Pepper holds 31.2 cm^3 of the delicious drink. For a New Years Eve party, you need enough juice to fill 6 cone- shaped glasses that have a 4cm diameter and a 3 cm height. How many full bottles of Dr. Pepper do you need to buy to completely fill the 6 glasses you need?
Approximately 3 bottles are needed to buy to completely fill the 6 glasses you need
Solution:
Given that,
A small bottle of Dr.Pepper holds 31.2 cm^3 of the delicious drink
Therefore,
[tex]Volume\ of\ small\ bottle\ of\ Dr.pepper = 31.2\ cm^3[/tex]
For a New Years Eve party, you need enough juice to fill 6 cone- shaped glasses that have a 4 cm diameter and a 3 cm height
Find the volume of cone
[tex]V = \frac{\pi r^2h}{3}[/tex]
Where, r is the radius and h is the height
Diameter = 4 cm
Radius = 4/2 = 2 cm
Height = 3 cm
Therefore,
[tex]V = \frac{3.14 \times 2^2 \times 3}{3}\\\\V = \frac{3.14 \times 12}{3}\\\\V = \frac{37.68}{3}\\\\V = 12.56[/tex]
Thus, for 6 cone shaped glasses:
Volume of 6 cone shaped galsses = 12.56 x 6 = 75.36 [tex]cm^3[/tex]
How many full bottles of Dr. Pepper do you need to buy to completely fill the 6 glasses you need?
[tex]\text{Number of Dr.pepper bottles } = \frac{\text{Volume of 6 cone shaped galsses}}{\text{Volume of small bottle of dr pepper}}\\\\\text{Number of Dr.pepper bottles } = \frac{75.36}{31.2}\\\\\text{Number of Dr.pepper bottles } = 2.4153[/tex]
Thus approximately 3 bottles are needed to buy to completely fill the 6 glasses you need
Final answer:
To fill 6 cone-shaped glasses for a New Year's Eve party, you would need to buy 3 full bottles of Dr. Pepper. The volume of each glass is calculated using the formula for the volume of a cone, and then this volume is multiplied by 6 to find the total volume required for all glasses. The number of bottles needed is found by dividing this total volume by the volume of one bottle of Dr. Pepper.
Explanation:
To determine how many full bottles of Dr. Pepper you need to buy to fill 6 cone-shaped glasses with a 4cm diameter and a 3cm height, we need to calculate the volume of one glass and then multiply it by 6 to get the total volume required. The formula to calculate the volume of a cone is V = (1/3)πr^2h, where V is the volume, r is the radius of the base, and h is the height of the cone.
First, we find the radius of the glass by dividing the diameter by two, which yields 2cm. Plugging the values into the formula, we get:
V = (1/3)π(2^2)(3) = (1/3)π(4)(3) = 4π cm^3
Since π is approximately 3.14, we can simplify this to:
V = 4(3.14) cm^3 = 12.56 cm^3 per glass.
Now, multiplying the volume of one glass by 6 gives us the total volume needed:
Total volume = 12.56 cm^3/glass × 6 glasses = 75.36 cm^3.
To find out how many bottles of Dr. Pepper are needed, we divide the total volume by the volume of one bottle:
Number of bottles = 75.36 cm^3 / 31.2 cm^3/bottle ≈ 2.415 bottles.
Since you cannot buy a fraction of a bottle, you would need to purchase 3 full bottles of Dr. Pepper to ensure you have enough to fill all 6 glasses.
The figure on the left represents a scale drawing of the figure on the right. What is the scale?
Answer:
[tex]\frac{1}{90}[/tex]
Step-by-step explanation:
Before calculating the scale we require the dimensions to be in the same units.
Using the conversion
1 yard = 3 ft and
1 foot = 12 inches, then
5 yards = 5 × 3 × 12 = 180 inches
The scale is then
2 in : 180 in ← divide both quantities by 2
= 1 : 90
= [tex]\frac{1}{90}[/tex]
The scale of the drawing given is 1/90
Using the following conversion :
1 yard = 3 feets 1 feet = 12 inchesThis means that ;
1 yard = 12 * 3 = 36 inchesThen ;
5 yards = 36 * 5 = 180 inchesRelating the expression :
2 inches = 180 inches
divide both sides by 2
1 inch : 90 inches
Hence, the scale is 1 /90

[tex]c=9.3\ units\\b=7.2\ units[/tex]
Part b) [tex]cos(B)=0.4[/tex] see the explanation
Step-by-step explanation:
The correct question is
In right triangle ABC, C is the right angle. Given measure of angle A = 40 degrees and a =6
Part a) which of the following are the lengths of the remaining two side, rounded to the nearest tenth?
Part b) Which of the following is cos B if sin A=0.4?
see the attached figure to better understand the problem
Part a)
step 1
Find the length of side c
Applying the law of sines
[tex]\frac{a}{sin(A)}=\frac{c}{sin(C)}[/tex]
we have
[tex]a=6\ units\\A=40^o\\C=90^o[/tex]
substitute
[tex]\frac{6}{sin(40^o)}=\frac{c}{sin(90^o)}[/tex]
solve for c
[tex]c=\frac{6}{sin(40^o)}=9.3\ units[/tex]
step 2
Find the length of side b
In the right triangle ABC
[tex]tan(40^o)=\frac{BC}{AC}[/tex] ----> by TOA (opposite side divided by the adjacent side)
substitute the values
[tex]tan(40^o)=\frac{6}{AC}[/tex]
[tex]AC=\frac{6}{tan(40^o)}=7.2\ units[/tex]
therefore
[tex]b=7.2\ units[/tex]
Part b) we know that
If two angles are complementary, the cofunction identities state that the sine of one equals the cosine of the other and vice versa
In this problem
Angle A and angle B are complementary
therefore
the sine of angle A equals the cosine of angle B
we have
sin(A)=0.4
so
cos(B)=0.4
The data depicted in a histogram show approximately a normal distribution if the distribution
bunches up on either end and tapers off toward the center
bunches up in the middle and tapers off symmetrically at either end
is relatively even from one end to the other
bunches up on one end and tapers off toward the other end
Answer:
bunches up in the middle and tapers off symmetrically at either end
Step-by-step explanation:
By definition a normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.
Because the data towards the mean is more frequent in occurrence, the graph peaks at the center. The data occurs less frequently at the tail ends of the distribution, thus the shape of the distribution is a bell shape that peaks at the center and tapers off towards the tails. The key characteristic is that the distribution of data is perfectly symmetrical.
This is why the answer is:
The data depicted in a histogram show approximately a normal distribution if the distribution bunches up in the middle and tapers off symmetrically at either end.

I am a fraction equivalent to 6/8 my numerator is 16 less than my denominator what fraction am i
Answer:
The answer is
[tex] \frac{48}{64} [/tex]
Step-by-step explanation:
Equivalent fractions are set of fractions which have the same value when simplified.
The equivalent fraction to 6/8 whose numerator is 16 less than its denominator can be obtained through two basic methods below.
Method 1
Multiply the numerator and denominator by 8 respectively.
[tex] \frac{6}{8} = \frac{6 \times 8}{8 \times 8} = \frac{48}{64} [/tex]
The numerator being 16 less than the denominator is:
[tex]48 - 64 = - 16[/tex]
Method 2
Find the equivalent fraction to 6/8 whose numerator is 16 less than its denominator by continuous multiplication approach. In other words, multiply 6/8 till you arrive at an equivalent fraction whose numerator is 16 less than its denominator. Simply multiply 6/8 by 2, 3, 4, 5, 6, 7, 8. Thus:
[tex] \frac{6}{8} = \frac{12}{16} = \frac{18}{24} = \frac{24}{32} = \frac{30}{40} = \frac{36}{48} = \frac{42}{56} = \frac{48}{64} [/tex]
The difference between the numerator and denominator of the equivalent fractions are: -2, -4, -6, -8, -10, -12, -14, -16
Hence, 48/64 is the equivalent fraction to 6/8 whose numerator and denominator difference is less than 16.
That is,
[tex] \frac{6}{8} = \frac{48}{64} [/tex]
Such that 48 - 64 = -16.
The fraction equivalent to 6/8 with a numerator 16 less than the denominator is 48/64, which simplifies to 3/4.
Explanation:To find an equivalent fraction to 6/8 where the numerator is 16 less than the denominator, we use an equation to represent the relationship between the numerator (N) and the denominator (D): N = D - 16. Since 6/8 can be simplified to 3/4 by dividing both the numerator and denominator by 2, we set up the following equation: N/D = 3/4.
By substituting N with (D - 16), we get (D - 16)/D = 3/4. To find the value of D, we cross multiply: 4(D - 16) = 3D. Solving for this, we have 4D - 64 = 3D, and therefore D = 64. Since N is 16 less than D, N = 64 - 16, which gives us N = 48. So, the fraction we are looking for is 48/64.
We can check that 48/64 is indeed equivalent to 3/4 by simplifying. Dividing both numerator and denominator by 16, we get 48/64 = 3/4. Thus, the student's fraction is 48/64 which simplifies to 3/4.

If f(x)=4x 2 +5x+2, then what is the remainder when f ( x ) is divided by x + 7?
Answer:
Step-by-step explanation:
Final answer:
The remainder when the function f(x) = 4x² + 5x + 2 is divided by x + 7 is found using the remainder theorem, which gives us a result of 163.
Explanation:
To find the remainder when the function f(x) = 4x² + 5x + 2 is divided by x + 7, we can use the remainder theorem. The remainder theorem states that if a polynomial f(x) is divided by a linear divisor of the form x - r, the remainder is f(r). Here, our linear divisor is x + 7, which we can rewrite as x - (-7). So, we substitute x = -7 into the polynomial to get the remainder.
Substituting x = -7 into the function gives us:
f(-7) = 4(-7)² + 5(-7) + 2 = 4(49) - 35 + 2 = 196 - 35 + 2 = 163.
Therefore, the remainder when f(x) is divided by x + 7 is 163.
