1 yard = 3 feet:
21 feet / 3 ft = 7 yards
12 feet / 3 feet = 4 yards
7 x 4 = 28 square yards
he will need 28 tiles
If ∠BAC = 120°, then the area of sector BAC is equal to 120 / 360 = 1/3 of the entire circle.
The 90 fl. oz is a better buy
3.99/25=0.15
6.99/90=0.07
Remark
The general equation for the point slope form is
(y - h) = slope(x - k)
<em><u>Givens</u></em>
given point = (5,7) from which
h = 7
k = 5
slope = m = - 13
Equation
(y - 7) = -13(x - 5) Usually the equation is left like this.
