I need help please help me! 5. Duane has a rectangular poster. The poster is similar to a rectangle that
measures 8
inches by 10 inches. Which of the following could be the dimensions of Duane's
poster?
A. 2 inches by 2 inches
B. 24 inches by 30 inches
C. 16 inches by 30 inches
D. 4 inches by 6 inches

B

Step-by-step explanation:

24/30 = 4/5

8/10 = 4/5

Answer B

B. 24 inches by 30 inches

Step-by-step explanation:

Since the poser is similar to a rectangle measuring 8 in. by 10 in., we have to find which solution has the same proportions.

When simplified, 8/10 = 4/5. That is our proportion.

A) 2/2 does not equal 4/5

B) 24/30 (when simplified) = 4/5

B is our right answer because when 8 is multiplied by 3, you get 24 and when 10 is multiplied by 3 as well (both multiplied by the same number to keep the proportions the same) you will get 30.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
