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
Answer: 14.96ft
Step-by-step explanation:
1. To solve this exercise you must apply the Pythagorean Theorem, which is:

Where
is the hypotenuse, and
and
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:


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.
X=-7/4,0
y=(0,7)
