Answer: 2
Step-by-step explanation:
80 x 50 x 60 is volume of tank
240000
Water is already filled to 45 so volume up to that is
80x 50 x 45 = 180000
Subtract to find the difference needed to fill tank
240000 - 180000 = 60000
Answer:
21.5 in. squared
Step-by-step explanation:
To find area of square:
radius × 2 is side length of square ( I am assuming it is a square)
all sides are the same on a square
10 × 10 = 100
To find area of circle
r^2 π
radius is five, to the second power is 25
times pi is 78.5
Subtract the area of circle from the area of the square to get the area of the shaded region
Coefficient is (-5)(-4) = 20.
Expo of x in the product is (x)(x^2) = x^3. That of y is (y^2)(y) = y^3.
Please, use "^" to denote exponentiation, as I have.
