Answer:
a. 78.6 square feet
b. $7.86
Step-by-step explanation:
a. This simply asks us to calculate the area of the 10 feet diameter pool
Formula for area of circle is ;
pi * r^2 = pi * d^2/4
so Area = 22/7 * 10^2/4 = 78.60 square feet
b. This will be the area of the blanket multiplied by the price per square foot of the blanket
Mathematically, we have that as;
78.60 * 0.1 = $7.86
Answer:
The correct answer would be...
c. 8(x + 4)(x - 7)
Hope this helps!
That's what I did and since the zeros would be -5 and 3 the answer would be 3 since it can't be a negative
(3/5 - 1/4)x = 350 where x = capacity of the basin
(7/20)x = 350
x = (350 *20) / 7 = 1000 mls Answer
