Pentagon PQRST is drawn on a coordinate plane below. what rule best represents a dilation to create pentagon PQRST with a scale factor of 1/2 and with the origin as the center of dilation?
Answers
Answer: [tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]
Step-by-step explanation:
Dilation is a transformation, in which the size of the image gets changed but not shape.The rule of dilation with scale factor k and wither origin as center of dilation :
(x,y) → (kx, ky)
Here , [tex]k= \dfrac12[/tex] , center of dilation = Origin
Then, the rule best represents a dilation to create pentagon PQRST will be :
[tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]

What is the surface area of the following triangular prism?
screenshot below :)
a. 24 yd 2
b. 96 yd 2
c. 50 yd 2
d. 90 yd 2
Answers
Answer:
The answer is 96 yd 2
Step-by-step explanation:
First for the triangle bases, you multiply the 3 by 4 and divide by 2 to get one base which is 6, then double it to get the other base on the top to get a total of 12. Then you just find the area of the other sides of the prism by multiplying the lengths and widths.
5x7=35
4x7=28
3x7=21
then you add all of the total values together:
35+28+21+12=96

Step-by-step explanation:
A rectangular prism has a length of 8 inches and a width of 6 inches. The lateral area is 84 square inches. What is the height of the prism?
Find the perimeter of the base.
P = 2l + 2w Perimeter of a rectangle
P = 2(8) + 2(6) Substitute: l = 8 and w = 6
P = 28
Use the formula for lateral area.
L = Ph
84 = (28)h Substitute: L = 84 and P = 28
h = 3 Solve for h.
The height of the prism is 3 inches.

Finally, use decimal numbers to write an expression that represents the net change in Rylee’s bank account balance for her entire shopping trip. Use your answers from parts A through C to guide you.
PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).

Step-by-step explanation:
PART C; The original price of Rylee’s groceries was $23.50. This money is leaving her bank account, so represent the amount with a negative sign:
-$23.50.
Rylee got a 20% discount on her purchase. In other words, she got 20% of her money back. The expression that represents the net change in her bank account is
-$23.50 – (-$23.50 × 0.2).
Further simplify the expression by factoring -$23.50 from both terms:
-$23.50 – (-$23.50 × 0.2)
=
-$23.50(1 – 0.2)
=
-$23.50(0.8).
The net change to her banking account balance is $83.22.
What is net change?The net change theorem states that when a quantity changes, the final value equals the initial value plus the integral of the rate of change. Net change can be a positive number, a negative number, or zero.
Given that, She spent $36.50 plus 8% tax. (to calculate the tax amount, we have to multiply the cost by the percentage in decimal form)
36.50 x (8/100) =$2.92 (value of tax)
Adding to the original cost
36.50+2.92 = $39.42
Then, she spent $25 to refuel her car at the gas station.
39.42 +25 = $64.42
She bought groceries worth $23.50. At the grocery checkout, she handed over a coupon for a 20% discount on her purchase
23.50 x (20/100) = 4.7 (amount of discount)
Subtracting to the purchase
23.50 -4.7= $18.8
Hence, adding to the total cost.
64.42 +18.8 = $83.22

"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
Answer:
twelve decreased by twice a number > 12 - 2x
8 times the sum of number and 4 > 8 (x + 4)
12 - 2x = 8 (x + 4) then 12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
