Pirate Jack has an equal number of gold and silver coins. If Pirate Jack splits all of his coins into 7 equal piles for his parrots, he has 4 coins left. Or, if he splits all of his coins into 11 equal piles for his shipmates, he has 4 coins left. Assuming every pile has at least 1 coin, what is the least possible number of coins Pirate Jack has?
The least possible number of coins Pirate Jack has, is 81 coins.
Step-by-step explanation:
Given,
When the coins are divided into 7 equal piles, 4 coins are left.
When the coins are divided into 11 equal piles, 4 coins are left.
We will take LCM of both 7 and 11.
7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, ....
11 = 11, 22, 33, 44, 55, 66, 77, 88, ...
The least common multiple of 7 and 11 is 77.
As 4 coins are left, therefore, we will add those coins.
Total possible coins = 77+4 = 81
The least possible number of coins Pirate Jack has, is 81 coins.

An image point of a transformation has coordinates Y'(2, -4). If the pre-image point had coordinates Y(6, -12), what was the transformation and scale factor?
reflection with scale factor 3
reflection with scale factor 1/3
dilation with scale factor 3
dilation with scale factor 1/3
Answer:
Therefore the correct answer is the fourth one d.) dilation with scale factor 1/3
Step-by-step explanation:
i) the pre-image co-ordinates is Y(6, -12)
ii) the coordinates of the image is Y' (2, -4)
iii) therefore we can clearly see that if we divide the coordinates of the pre-image (6,-12) by 3 then we get the coordinates of the image(2,4).
Therefore this is a dilation with scale factor of 1/3.
Therefore the correct answer is the fourth one d.) dilation with scale factor 1/3
Final answer:
The transformation from the pre-image point Y(6, -12) to the image point Y'(2, -4) is a dilation with a scale factor of 1/3.
Explanation:
Given an image point Y'(2, -4) of a transformation and the pre-image point Y(6, -12), we can determine the type of transformation and the scale factor. The transformation is a type of change that affects the position, size, or shape of a figure. To find out the type of transformation and the scale factor, we compare coordinates.
Since the x-coordinate changed from 6 to 2, it has been reduced by a factor of 3 (6 divided by 3 equals 2). The y-coordinate changed from -12 to -4, which also has been reduced by a factor of 3 (-12 divided by 3 equals -4). This consistent reduction indicates that the transformation is a dilation. The objects are shrunk uniformly in both dimensions by the scale factor.
The correct answer is therefore dilation with scale factor 1/3.

The question is about calculating the center of mass for a triangular sandwich with a semicircular bite and determining the volume and uncertainty for a rectangular box.
Explanation:The question asked concerns finding the center of mass of a triangular sandwich after taking a semicircular bite out of it, which is a problem related to geometry and mass distribution. When solving such problems, one would typically have to calculate the area of the original triangle and the area of the semicircular bite, then find the centroid of both shapes.
For the rectangular box's volume and uncertainty, this is a measurement and uncertainty calculation question. Here, one must apply the formula for the volume of a rectangle (length imes width imes height) and use the rules of propagation of uncertainty to calculate the overall uncertainty of the volume measurement.
A survey of 260 families show that 99 had dog 76 had cat 34 had dog and cat 98 had neither a cat nor a dog nor a parakeet 8 had a cat a dog and a parakeet
The number of parakeet is 21.
The calculation is as follows:
Let us assume the families had parakeet only be X
A survey of 260 families show that:
The families had a dog and a cat only it means
= 34 - 8
= 26
The families had a dog only is
= 99 - (26 + 8 )
= 65
The families had a cat only is
= 76 - (26 + 8)
= 42
So,
X = 260 - ( 98 + 8 + 26 + 65 + 42 )
= 260 - 239
= 21
Therefore, the families had a parakeet only is 21.

In triangle VWX, VW = 4.5 inches, WX = 5.9 inches, Measure of angle W = 28 degrees, and Measure of angle X = 47 degrees. If Triangle P Q R is congruent to triangle W V X, which statement is true?
a.QR = 4.5 cm
b.QR = 5.9 cm
c.Measure of angle R = 28 degrees
d.Measure of angle R = 47 degrees
The true statement about triangle is: b. QR = 5.9 cm.
To understand what it means for two triangles to be congruent. When two triangles are congruent (△PQR ≌ △WVX), all corresponding sides and angles are equal.
Given:
VW = 4.5 inchesWX = 5.9 inches∠W = 28°∠X = 47°For the triangles to be congruent, the corresponding sides and angles must be equal. Let's match the corresponding parts:
QR corresponds to WXPQ corresponds to VWm∠R corresponds to m∠Wm∠Q corresponds to m∠XGiven this correspondence:
QR must be equal to WX, so QR = 5.9 inches (Option b).
m∠R must be equal to m∠W, so m∠R = 28° (Option c).
m∠Q must be equal to m∠X, so m∠Q = 47° (Option d).
However, m∠R and m∠Q cannot both be correct choices simultaneously; only one can be correct because they refer to the same angle in each corresponding pair QR = 5.9 inches is the correct choice considering the triangle sides.

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-4, -2), B(-2, -2), C(-2, 7)C(−2,7)C, D(-4, 7
What is the area of rectangle ABCD?
Answer:
The area of rectangle ABCD is [tex]18\ units^2[/tex]
Step-by-step explanation:
Plot the figure to better understand the problem
we have the vertices
A(-4, -2), B(-2, -2), C(-2, 7), D(-4, 7)
see the attached figure
The area of the rectangle is equal to
[tex]A=LW[/tex]
where
L is the length
W is the width
In this problem we have
[tex]L=BC=7-(-2)=9\ units[/tex] ---> difference of the y-coordinates
[tex]W=AB=-2-(-4)=2\ units[/tex] ---> difference of the x-coordinates
substitute
[tex]A=(9)(2)=18\ units^2[/tex]
Final answer:
The area of rectangle ABCD is calculated as 18 square units by finding the product of its width (2 units) and height (9 units).
Explanation:
The area of rectangle ABCD with vertices A(-4, -2), B(-2, -2), C(-2, 7), and D(-4, 7) can be calculated by finding the lengths of the sides AB and BC. The length of AB (width) is the difference in the x-coordinates of A and B, which is |-2 - (-4)| = 2.
The length of BC (height) is the difference in the y-coordinates of B and C, which is |7 - (-2)| = 9. Therefore, the area of rectangle ABCD is the product of the width and height, which is 2 * 9 = 18 square units.

Solve the system of equations.
A) a = 5, b = 5
B) a = 2, b = 8
C) a = 6, b = 4
D) a = 3, b = 7
E) a = 12, b = -2
Answer:
C) a = 6, b = 4
Step-by-step explanation:
6 + 4 = 10
6 - 4 = 2
To solve the system, we first add both equations to find 'a = 6'. Then, substitute 'a' in one of the original equations to get 'b = 4'. The solution is 'a = 6' and 'b = 4', corresponding to answer choice C).
Explanation:To solve the system of equations:
a + b = 10a - b = 2We can add the two equations to eliminate the variable b. By adding them, we get:
2a = 12
Divide both sides of the equation by 2:
a = 6
With the value of a known, substitute a = 6 into either of the original equations. For example, substituting it into the first equation:
a + b = 10
6 + b = 10
b = 10 - 6
b = 4
Therefore, the solution to the system of equations is a = 6 and b = 4, which corresponds to answer choice C).

Ramesh says that based on the pattern 7^-5 =-16,807 which statement explains were her Ramesh is correct?
Ramesh is not correct because as the exponents decrease, the previous value is divided by 7 .
Explanation:
An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
Exponents are superscript numerals that let you know how many times you should multiply a number by itself. Some real world applications include understanding scientific scales like the pH scale or the Richter scale, using scientific notation to write very large or very small numbers and taking measurements.
Answer:
D. Ramesh is not correct because as the exponents decrease, the previous value is divided by 7, so 7 Superscript negative 5 = 1 divided by 7 divided by 7 divided by 7 divided by 7 divided by 7 = StartFraction 1 Over 16,807 EndFractionStep-by-step explanation:

12abx square - (9a square - 8b square)x - 6ab =0
The value of x is [tex]\frac{3a}{4b}[/tex] and [tex]-\frac{2b}{3a}[/tex]
Explanation:
The expression is [tex]12abx^{2} -(9a^{2} -8b^{2} )x-6ab=0[/tex]
Multiplying the term x withing the bracket, we get,
[tex]12abx^{2} -9a^{2} x+8b^{2} x-6ab=0[/tex]
Grouping the terms, we have,
[tex](12abx^{2} -9a^{2} x)+(8b^{2} x-6ab)=0[/tex]
Taking out the common terms in each bracket, we get,
[tex]3ax(4bx -3a)+2b(4bx-3a)=0[/tex]
Simplifying, we get,
[tex](3ax+2b)(4bx -3a)=0[/tex]
Equating each term to zero, we get,
[tex]\begin{aligned}3 a x+2 b &=0 \\3 a x &=-2 b \\x &=-\frac{2 b}{3 a}\end{aligned}[/tex] and [tex]\begin{aligned}4 b x-3 a &=0 \\4 b x &=3 a \\x &=\frac{3 a}{4 b}\end{aligned}[/tex]
Hence, the values of x is [tex]\frac{3a}{4b}[/tex] and [tex]-\frac{2b}{3a}[/tex]
Ben bowled 121 and 184 in his first two games. What must he bowl in his third game to have an average of at least 170?
Answer:
205
Step-by-step explanation:
Were gonna start by writing an equation (121+184+x)/3=170 because were adding a 3rd value to the average and x is going to be our value that were looking for. If you solve that, you get 205. Hope this helps.
For Ben to have an average of at least 170 in his third game, he must bowl a score of 205.
Explanation:To find out what Ben must bowl in his third game to have an average of at least 170, we can use the formula for average: average = total score/number of games.
In this case, Ben has played two games and wants to have an average of 170. So we can set up the equation: 170 = (121 + 184 + x) / 3, where x represents his score in the third game.
To solve for x, we can multiply both sides of the equation by 3 to get rid of the fraction: 510 = 121 + 184 + x.
Then, we can combine the numbers on the right side: 510 = 305 + x.
Finally, subtracting 305 from both sides gives us: 205 = x.
Therefore, Ben must bowl a score of 205 in his third game to have an average of at least 170.

Lin can fill 7.5 glasses of water from a 1 1/2 liter bottle. However, if only full glasses are counted, Lin can fill 7 full glasses.
Explanation:The question asks how many 1/5 liter glasses can be filled with a 1 1/2 liter bottle of water. To answer this, we need to perform a division of the total volume of the water by the volume of each glass.
First, express both quantities in the same units, in liters. The bottle has 1 1/2 liters, which is the same as 1.5 liters. Now, divide the total volume of the water by the volume of one glass:
1.5 liters / (1/5 liter per glass) = 1.5 * 5 = 7.5 glasses.
Therefore, Lin can fill 7.5 glasses of water from a 1 1/2 liter bottle, if we consider that partial glasses can be filled. If only full glasses can be filled, Lin can fill 7 full glasses.
The sum of two numbers is 14. Their difference is –146. Find the numbers.
Answer:
-66, 80
Step-by-step explanation:
Let x represent the first number. Then the second number is 14-x, and the difference is ...
x - (14-x) = -146
2x = -132 . . . . . . add 14, collect terms
x = -66 . . . . . . . . the first number
14-x = 14-(-66) = 80 . . . . . . the second number
Answer:
-66 & 80
Step-by-step explanation:
Let the two numbers be x and y
x + y = 14 (1)
x - y = -146 (2)
Adding (1) & (2),
2x = -132
x = -66
y = 14 - x = 14 - (-66) = 14 + 66
y = 80
Which of the following must be true in order for SAND to be in a rhombus? Select all that apply
a) Consecutive sides must be congruent, for SAND to be in a rhombus
For the word "SAND" to form a rhombus, certain conditions must be met based on the properties of a rhombus:
a) Consecutive sides must be congruent: True. In a rhombus, all sides are congruent, so consecutive sides must also be congruent.
b) Diagonals do not bisect the angles: False. In a rhombus, the diagonals bisect the angles. This is a property of rhombuses.
c) All interior angles add up to 360: False. In a rhombus, all interior angles are equal, but their sum is not necessarily 360 degrees. However, the sum of all interior angles in any quadrilateral (including a rhombus) is indeed 360 degrees.
Therefore, the correct statement is:
a) Consecutive sides must be congruent
