cestrela7 [59]

Given,

Length of the rectangle piece of fabric, l = 5 yards

Width of the rectangular piece of fabric, b = 19 inches

To find,

The length of the diagonal.

Solution,

The relation between Yards and inches is :

1 Yard = 36 inches

5 yards = 180 inches

Let x be the diagonal. It can be calculated as :

$x=\sqrt{l^2+b^2} \\\\x=\sqrt{180^2+19^2} \\\\x=181\ inches$

Hence, the length of the diagonal is 181 inches

Jim adds 20 to it, then doubles it and gets an answer of 99.2. What was the original number?

riadik2000 [5.3K]

(n+20)*2 = 99.2

distribute

2n + 40 = 99.2

subtract 40 from each side

2n = 59.2

divide each side by 2

n = 29.6
