The tree was approximately 40.8ft tall.

You use the equation, a^2+b^2=c^2.
12^2 + 39^2 = x^2, add the results of 12^2 and 39^2 to make 1665 = x^2. You can take the positive root of both sides, 3√185, and it equals 40.80441152, which is rounded to 40.8.

A map distance of 5 inches represents 200 miles of actual distance . Suppose the distance between two cities on the map is 7 inc

Naily [24]

$\frac{5}{200} = \frac{7}{x} \\ 5x = 1400 \\ x = 280$

therefore, the actual distance is 280 miles.

Problem solving your family has a rectangular pool that measures 18 feet by 9 feet. your family wants to put a deck around the p

tester [92]

Let w be the width of the deck. Then, using the total area, we get:
(9+2w)(18+2w)=400
4w²+54w-238=0
2w²+27w-119=0
(2w-7)(w+17)=0
w=-17 or 7/2
Using the positive value, we get a width of 3&1/2 ft. for the deck
