Correct Answers only please!

A student sketched some art on an 8.5 inch x 11 inch piece of paper. He wants to resize it to fit an 5 inch x 7 inch frame (as shown below)


What is the value of x? (Hint: Like Step #1 of the example in class)



A. x = 5


B. x = 6


C. x = 5.41


D. x = 7

Answer 1

Answer: A. x= 5"

Explanation:

ORIGINAL/NEW = 11"/7" = 8.5"/x

x = 7" x 8.5"/11" = 59.5"/11 = 5.409 ≅ 5.41"

If we wanted to keep most of the engraving, we would adjust the larger dimension, but we have been asked to adjust one dimension to 5", since it is said that C. x = 5.41 is incorrect

Then we will adjust the minor dimension to 5"

ORIGINAL/NEW = 11"/y = 8.5"/5"

y= 11" x 5"/8.5" = 6.47"

Then the new dimensions of the paper are 6.47" x 5" to fit an 7" x 5" frame

Answer: A. x= 5"
