Answer:
gallons of water will be needed to fill the pool 19388.16 gallons
Step-by-step explanation:
given data
Length of rectangular pool = 36 feet
Width of rectangular pool = 18 feet
1 cubic foot = 7.48 gallons water
solution
we consider here Depth of rectangular pool = 4 feet
so Volume of the pool = Length × Width × Depth ..............................1
put here value
Volume of the pool = 36 × 18 × 4
Volume of the pool = 2592 cubic feet
and
1 cubic feet = 7.48 gallons
so 2592 cubic feet will be
2592 cubic feet = 7.48 × 2592
2592 cubic feet = 19388.16 gallons
Answer:
xy = 1
k = 79
Step-by-step explanation:
Question One
The first and third frames look to me to be the same. I'll treat them that way.
y = x^2 Equate y = x^2 to the result of 2y + 6 = 2x + 6
2y + 6 = 2(x + 3) Remove the brackets
2y + 6 = 2x + 6 Subtract 6 from both sides
2y = 2x Divide by 2
y = x
Now solve these two equations.
so x^2 = x
x > 0
1 solution is x = 0 from which y = 0. This won't work. x must be greater than 0. So the other is
x(x) = x Divide both sides by x
x = 1
y = x^2 Put x = 1 into x^2
y = 1^2 Solve
y = 1
The second solution is
(1,1)
xy = 1*1
xy = 1
Answer: A
Question Two
square root(k + 2) - x = 0
Subtract x from both sides
sqrt(k + 2) = x Square both sides
k + 2 = x^2 Let x = 9
k + 2 = 9^2 Square 9
k + 2 = 81
k = 81 - 2
k = 79
