A painter needs to paint the bottom of a circular pool. The pool has a radius of 30 feet. A store sells 5-gallon cans of paint.
oksano4ka [1.4K]

Answer:

2 cans

Step-by-step explanation:

Given that :

Radius of pool = 30 feets

Using the relation for the Area of a circle :

Area = pi*r^2

Thus,

Area of pool = 3.14 * 30^2

Area of pool = 3.14 * 900 = 2826feet²

Paints are sold in cans of 5 gallon

5 gallon of paint = 1500 feet²

Least number of 5 gallon can required :

2826 feet² / 1500 feet² = 1.884 cans

Hence,

Least number of 5 gallon can required = 2 cans

What is the length of the side of a right triangle that has a side length of 12in and a hypotenuse that measures 15ft
Viktor [21]

Answer: 14.96ft


Step-by-step explanation:

  1. To solve this exercise you must apply the Pythagorean Theorem, which is:

a=\sqrt{b^{2}+c^{2}}

Where a is the hypotenuse, and b and c are the other sides of the triangle.

2. You have that the sides given measures 12 inches. 1 feet has 12 inches. Therefore, this side measures 1 feet.

2. Then, when you  solve for one of the sides and substitute the values given in the problem into the formula shown above, you obtain that the length of  the side of the rigth triangle is:

 b=\sqrt{(15ft)^{2}-(1ft)^{2}}

b=4\sqrt{14}=14.96ft

What is the equation of this line in slope intercept form: -8x-2y=10?
frez [133]
Since you are writing this in slope-intercept equation you will want to isolate the y. Therefore move the -8x over making it into -2y=8x+10. Then simply divide by the -2. And your equation will be y=-4x-5.
