Kia purchased 3 pounds of grapes and spent $11.63 on other items. She spent a total of $20. She used the following steps to find

Maurinko [17]

3x + 11.63 = 20
3x + 11.63 - 11.63 = 20 - 11.63
3x = 8.37

by subtracting the 11.63 from both sides, this tells us how much the grapes cost....not per lb., but for the total of all the grapes.

Please help !! Use Pythagorean theorem :) and show your work if you can thanks :”) will give b

g100num [7]

Answer:

$b=\sqrt{1575}$ ≈ 39.7ft

Step-by-step explanation:

The Pythagorean theorem:

$a^{2}+ b^{2}= c^{2}$

(a and b are the two shorter legs and c is the largest leg, which is also the opposite side of the right angle)

First, the value of a and c is given. So, we can go ahead and plug those value in and then solve for b.

$45^{2}+ b^{2}= 60^{2}$

$2025+b^{2} =3600$

To find b, we have to get it by itself. So we subtract 2025 from both sides then square root both sides. Resulting in:

$b^{2} =1575$

$b=\sqrt{1575}$ ≈ 39.7ft
