A parallelogram is dilated by a scale factor of 1/4 to produce a new parallelogram. Which of the following best describes the relationship of the area of the new parallelogram to the area of the original parallelogram?
The area of the new parallelogram is 1/2 the area of the original parallelogram.
The area of the new parallelogram is 1/4 the area of the original parallelogram.
The area of the new parallelogram is 1/16 the area of the original parallelogram.
The area of the new parallelogram is 1/8 the area of the original parallelogram.
Answer: The answer is 1/6.
Step-by-step explanation:
1/4 ^2 = 0.0625 which = 1/16.
The area of the new parallelogram is 1/16 the area of the original parallelogram statement best describes the relationship of the area of the new parallelogram to the area of the original parallelogram.
When a shape is dilated by a scale factor of "k," the area of the new shape is equal to the original area multiplied by the square of the scale factor.
The given scale factor is 1/4.
Therefore, the area of the new parallelogram would be (1/4)² = 1/16 of the area of the original parallelogram.
Hennce, "The area of the new parallelogram is 1/16 the area of the original parallelogram."

A. 9
B. 9 square root of 2
C. 18
D. 18 square root of 2
Answer:
B
Step-by-step explanation:
We are given a right triangle with angles 45, 90, and 45
With this type of right triangle, the ratio of the sides are 1:1:square root of 2
We are also given that the hypotenuse is 18
This means that the sides are in the ratio of x:x:x(square root of 2)
Since 18 is the hypotenuse, we can form the equation of-
18 = x(square root of 2)
18/(square root of 2)=x
x= 9 square root of 2
since y=x, y= 9 square root of 2

Write an equation of the line that passes through the given points
Answer:
y=4x-7
Step-by-step explanation:
We know that the y intercept is -7 so we can have y=mx-7
And we can get the slope by using the slope formula (y2-y1)/(x2-x1)=m
(2,1) (0,-7)
x1 y1 x2 y2
(-7-1)/(0-2)
-8/-2 = 4
m=4
So just plug it into the equation to get:
y=4x-7
Answer:
y = 4x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the t- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (0, - 7)
m = [tex]\frac{-7-1}{0-2}[/tex] = [tex]\frac{-8}{-2}[/tex] = 4
The line crosses the y- axis at (0, - 7) ⇒ c = - 7
y = 4x - 7 ← equation of line

Tim sells two types of pizza. He charges
$10 for a cheese pizza and $15 for a
pepperoni pizza. Yesterday he sold
64 pizzas in all. For every cheese pizza,
he sells 3 pepperoni pizzas. How much
money did he make selling pizzas
yesterday?
Answer:
answer must be $880.
48 papperoni pizza =48 * 15= 720
16 cheese pizza =16 * 10= 160
Total sell =$880
He make $880 for selling pizzas yesterday.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Tim sells two types of pizza. He charges $10 for a cheese pizza and $15 for a pepperoni pizza.
And, Yesterday he sold 64 pizzas in all. For every cheese pizza, he sells 3 pepperoni pizzas.
Now,
Since, For every cheese pizza, he sells 3 pepperoni pizzas.
Hence, Let number of cheese pizza = x
Then, Number of pepperoni pizzas = 3x
Since, Yesterday he sold 64 pizzas in all.
So, We get;
⇒ x + 3x = 64
⇒ 4x = 64
⇒ x = 16
Thus, Number of cheese pizza = x = 16
Then, Number of pepperoni pizzas = 3x
= 3 × 16
= 48
So, The cost of 16 cheese pizza and 48 pepperoni pizza are;
⇒ Total cost = 16 × $10 + 48 × $15
⇒ Total cost = $160 + $720
⇒ Total cost = $880
Thus, He make $880 for selling pizzas yesterday.

Which expression represents the sum of 31 and 104,
divided by 3?
Answer:
The answer is 45Step-by-step explanation:
Well all you really need to do is add 31 and 104 which is 135 then divide it by 3 and well you got the answer 45
The expression (31 + 104) / 3 is equal to 45.
The expression that represents the sum of 31 and 104, divided by 3, can be written as (31 + 104) / 3.
To calculate the value, we start by evaluating the sum of 31 and 104, which gives us 135. So, the expression becomes 135 / 3.
Dividing 135 by 3 yields a result of 45.
Therefore, (31 + 104) / 3 is equal to 45.
The expression simplifies the process of finding the sum of the two numbers (31 and 104) by first adding them together and then dividing the sum by 3. This calculation provides a concise representation of the desired arithmetic operation and its solution.

What is the image of (7,8) after a reflection over the line y = –x
Answer:
(-7. -8) Just flip the signs.
Answer:
[tex]\boxed {\boxed {\sf (-8,-7)}}[/tex]
Step-by-step explanation:
When a point is reflected over y=-x, the following change occurs:
[tex](x,y)[/tex] ⇒ [tex](-y, -x)[/tex]
We are given the point (7,8).
Essentially, we change the signs for both coordinates, then flip the x-coordinate and y-coordinate.
1. Change the signs
[tex](7,8)[/tex] ⇒ [tex](-7,-8)[/tex]
2. Flip the x and y coordinates
[tex](-7,-8)[/tex] ⇒ [tex](-8,-7)[/tex]
So the image of (7,8) after a reflection over y=-x is (-8,-7)

y varies inversely as X. y=4 when x=2. Find y when x=16
Answer:
y = 32 (Verified Answer) ✅Step-by-step explanation:
We will use a proportion to solve this.
[tex]\frac{2}{4} = \frac{16}{y}[/tex]
Now, we cross multiply.
2y = 16 x 4
2y = 64
Now, we must divide by 2 to get the correct value for y
y = 64/2
y = 32
Now, we can use the same proportion to check our answer.
2(32) = 16 x 4
64 = 64 ✅

Which number is missing from the following prime factorization expression? 792 = __ x 2 x 2 x 2 x 3 x 11 A. 2 B. 3 C. 5 D. 7
Answer:
3
Step-by-step explanation:
Evaluate 2 x 2 x 2 x 3 x 11 (better written as 2·2·2·3·11, because "x" is a variable name, not a math operator).
2·2·2·3·11 = 8·33 = 264
Then divide 792 by this 264 to find the final factor:
final factor = 792/264 = 3
Then the prime factorization of 792 is 2·2·2·3·3·11
which we obtained by multiplying 2 x 2 x 2 x 3 x 11 by 3.
