The inequality p > 64 represents the total number of pieces he has ⇒ D
Step-by-step explanation:
Let us revise the inequality words
Less than ⇒ <More than ⇒ >At least ⇒ ≥At most ⇒ ≤∵ Ashton makes more than 32 sandwiches for a party
∴ The number of sandwiches > 32
∵ Ashton cuts each sandwich into two pieces
- That the number of pieces is the number of sandwiches times 2
∴ The number of pieces > 2 × 32
∴ The number of pieces > 64
- The number of pieces is p
∴ p > 64
The inequality p > 64 represents the total number of pieces he has

What simplified ratio correctly compares 27 feet to 36 feet?
The simplified ratio that correctly compares 27 feet to 36 feet is 3:4
Step-by-step explanation:
Step 1: Simplify the ratio by finding common factor
Step 2: Here, in this case the lowest common factor is 3. Divide both numerator and denominator by 3.
⇒ 27/36 = 9/12 (on dividing by 3)
⇒ 9/12 = 3/4 (again on dividing by 3)
Triangles PQR and XYZ are similar. What is the length of XZ? 6 5.25 3.5 2.57
Option B: 5.25 is the length of XZ
Explanation:
The triangles PQR and XYZ are similar.
To determine the length of XZ, let us use the similarity theorem.
The theorem states that, "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".
Thus,
[tex]\frac{QR}{YZ} =\frac{PR}{XZ}[/tex]
Let us substitute the values from the diagram, we have,
[tex]\frac{4}{3} =\frac{7}{XZ}[/tex]
Multiplying both sides by 3, we get,
[tex]4 =\frac{21}{XZ}[/tex]
Thus,
[tex]XZ =\frac{21}{4}=5.25[/tex]
Thus, the length of XZ is 5.25
Hence, Option B is the correct answer.
Graph the function y=-2x+6
Answer:
See photo
Step-by-step explanation:
The line is in slope-intercept form which looks like y = mx + b.
"x" and "y" represent points on the line.
"m" is the slope (how steep the line is) and if the line goes up (+) or down (-).
"b" is the y-intercept, which is where the graph hits the y-axis.
Take information from the equation y=-2x+6. Use the slope and the y-intercept to graph to line.
m = -2 = [tex]-\frac{2}{1}[/tex] (Fraction form).
b = 6
Plot a point at the y-intercept on the y-axis
If the y-intercept is 6, so you plot the point at (0, 6). (The y-intercept occurs when x = 0).
Find another point
Count the number of rise and run from the y-intercept.
Remember the slope is [tex]\frac{rise}{run}[/tex]
Run is the number of squares moving right. Rise is the number of squares moving up (if positive) or down (if negative).
Since the slope is -2/1, move two squares down and one square to the right to find another point on the line.
Connect the points
You only need two points to make a line. If you want the line to be longer, you can extend it with a ruler.
Other formatting rules
Remember to add arrows at the ends of the x and y axis.
Also, add arrows to the ends of the the line that you graphed.
Most teachers ask you to label the line with the equation.
quadratic function of 13 and 2
Answer:
[tex]f(x) = {x}^{2} - 15x + 26[/tex]
Step-by-step explanation:
Assuming we want to write a quadratic function with intercepts x=13 and x=2.
Then we can work backwards.
This means that:
x-13=0 and x-2=0
The factored form of this quadratic function becomes:
[tex]f(x) = (x - 13)(x - 2)[/tex]
We expand to get:
[tex]f(x) = {x}^{2} - 2x - 13x + 26[/tex]
We simplify to obtain:
[tex]f(x) = {x}^{2} - 15x + 26[/tex]

A rectangular garden is 5 feet long and 3 feet wide. A second rectangular garden has dimensions that are double the dimensions of the first garden. What is the percent of change in perimeter from the first garden to the second garden?
Percentage change in perimeter is 100%.
Step-by-step explanation:
Step 1: Given length of rectangle 1, length = 5 ft and breadth = 3 ft.Calculate perimeter of R1 = 2 (length + breadth) = 2 (5 + 3) = 16 ft
Step 2: Given dimensions of 2nd rectangle is twice the first, length = 10 ft and breadth = 6 ft.Calculate perimeter of R2 = 2 (10 + 6) = 32 ft
Step 3: Calculate percentage change using the formula, (R2 - R1/R1) [tex]\times[/tex] 100= (32 - 16/16) [tex]\times[/tex] 100 = 100%

A circle circumference is approximately 76 cm estimate the radius diameter and area of the circle
Answer: r = 12.1cm, d = 24.2cm, Area = 460.0cm²
Step-by-step explanation:
From the formula,
Circumference of a circle = πd or 2πr.
To find the radius, we have to equate 76 cm to πd or 2πr and make r or d the subject of the formula. Now
76 = 2πr, don't forget that
π = 22/7 or 3.142
Now make r the subject of the formula
r = 76/2π
= 76/2 x 3.142
= 76/6.284
= 12.1 cm
d = 2r
= 2 x 12.1
= 24.2cm.
Area of the circle is πr²
= 3.142 x (12.1)²
= 3.142 x 146.41
= 460.0 cm²

What is an equivalent fractions to 5/12
Answer:
exact form is 5/12
decimal form is 0.416666
Step-by-step explanation:
Equivalent fractions are fractions that have the same value or proportion. To find an equivalent fraction to a given fraction, you multiply or divide both the numerator and the denominator by the same number. Therefore, 10/24 and 15/36 are equivalent fractions to 5/12.
Explanation:To find an equivalent fraction to 5/12, you simply multiply or divide both the numerator (the top number) and the denominator (the bottom number) by the same non-zero number. An equivalent fraction will have a different numerator and denominator, but it will represent the same value or proportion. For example, if we multiply both the numerator and the denominator of 5/12 by 2, we get 10/24. Therefore, 10/24 is an equivalent fraction to 5/12.
Similarly, if we multiply 5 (the numerator) and 12 (the denominator) by 3, we get the equivalent fraction 15/36.
So, 5/12 = 10/24 = 15/36 in terms of value or proportion.

At 10 percent interest, how long does it take to quadruple your money?
Group of answer choices
15.36 years
14.33 years
15.11 years
14.55 years
15.56 years
It takes about 14.55 years for quadruple your money
Solution:
Given that,
At 10 percent interest, how long does it take to quadruple your money
Rule of 144:
The Rule of 144 will tell you how long it will take an investment to quadruple
Here,
Rate of interest = 10 %
Therefore, number of years to quadruple your money is obtained by dividing 144 by 10
Rule of 144 Formula:
[tex]N = \frac{144}{R}[/tex]
Where:
N = Number of many years times.
144 = Is the constant variable.
R = Rate of interest.
[tex]\rightarrow N = \frac{144}{10} = 14.4[/tex]
Thus it takes about 14.4 years for quadruple your money.
Another method:
If initial amount is $ 1 and it if quadruples it should be $ 4
We have to find the number of years if rate of interest is 10 %
Let "n" be the number of years
Then we can say,
[tex]Amount = Principal(1+\frac{R}{100})^n[/tex]
[tex]4 = 1(1+\frac{10}{100})^n[/tex]
[tex]4 = 1(1+0.1)^n\\\\4= 1(1.1)^n\\\\4 = 1.1^n\\\\We\ know\ that,\\\\(1.1)^{14.55} = 1.1^n\\\\We\ know\ that\\\\If\ a^m = a^n\ then\ m = n\\\\Therefore,\\\\14.55 = n\\\\n = 14.55[/tex]
Thus Option D 14.55 years is correct

Tom has read 2 books for school. Tom read 1/2 of the first book on Thursday and 5/12 of the second book on Friday. What total fraction of these two books has Tom read
Answer:
35/12
Step-by-step explanation:
1 1/2+1 5/12
=3/2+17/12
=3*6+17*1/12
=18+17/12
=35/12
Tom read a total of 11/12 of the two books combined by reading 1/2 of the first book and 5/12 of the second book, after finding a common denominator to add the fractions.
Explanation:To calculate the total fraction of the two books that Tom has read, we need to add the fractions of each book he has read together. Tom read 1/2 of the first book and 5/12 of the second book.
To add these fractions, they need to have a common denominator. The lowest common denominator between 2 and 12 is 12.
Therefore, we convert 1/2 into 6/12 so that both fractions have the same denominator.
Now, the fractions to be added are 6/12 (from the first book) and 5/12 (from the second book).
Adding these fractions, we get:
6/12 + 5/12 = 11/12
So, Tom has read a total of 11/12 of the two books combined. This method of finding a common denominator and then adding the numerators is an effective strategy to add fractions with different denominators, providing a clear, step-by-step approach to solving such problems in mathematics.
Which of the following is the value of f(3) in the function below? f(x)=2x-1
Answer:
F(3) = 2 * 3 - 1, which is 6 - 1 equaling 5.
Step-by-step explanation:
3 times 2 is six since you have to follow PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction). Multiplication is before Subtraction, and that is why we multiply 2 and 3 first, since 3 replaces the variable x. After multiplying 2 and 3 to get 6, subtract by 1 to get 5.

Answer: 1.9
Step-by-step explanation:
because you keep adding 1.9 to get your result
Answer:

if you add 2.4 to one of the numbers in the sequence it will be the next number.
1.5 + 2.4 = 3.9
3.9 + 2.4 = 6.3
6.3 + 2.4 = 8.7
