Anna takes a rectangular piece of fabric and makes a diagonal from one corner to the opposite corner. The diagonal cut is 26 inches and the length is 24 inches. What is the width of the rectangular piece of fabric, rounded to the nearest tenth if necessary?

10 inches

Step-by-step explanation:

To solve the above question, we use the formula:

D² = L² + W²

Where

D = Diagonal = 26 inches

L = Length = 24 inches

W = Width

Hence:

W² = D² - L²

W = √D² - L²

W = √26² - 24²

W = √676 - 576

W = √100

W = 10 inches

Therefore, the width of the rectangular piece of fabric is 10 inches.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
