Answer:
15
Step-by-step explanation:
Hypotenuse: 17ft long
Height: 8ft long
17^2 = 8^2 + b^2
b^2 = 17^2 - 8^2
b = √225
b = 15
The answer should be 15/24 of an ouce beacause 35 minus 5 ounces because the box weighs 5 ounces when it is empty. Then, you need to do 30 dibided by to to get 30/48 which is reduced to 15/24.
$ 7 dollar reduction....that means new price is (32 - 7) = 25
percent decrease = (original number - new number) / original number..* 100
(32 - 25) / 25....* 100
7/25 * 100
0.28 * 100
28% decrease <==
Answer:
42
Step-by-step explanation:
-2 sqrt (20) -sqrt(125)
-2 sqrt(4*5) - sqrt(25*5)
-2 sqrt(4)sqrt(5) -sqrt(25)sqrt(5)
-2 *2*sqrt(5) -5sqrt(5)
-4sqrt(5) -5sqrt(5)
-8sqrt(5)
