Find the volume of a pyramid with a square base, where the perimeter of the base is
Liula [17]

Answer:

  33.4 m^3

Step-by-step explanation:

The edge length of the base is 1/4 of the perimeter, so is ...

  (10.3 m)/4 = 2.575 m

Then the area of the base is the square of this, or ...

  B = (2.575 m)^2 = 6.630625 m^2

The volume is ...

  V = (1/3)Bh = (1/3)(6.630625 m^2)(15.1 m) ≈ 33.4 m^3

The volume of the pyramid is about 33.4 cubic meters.

The product of two numbers is 713. The first number is 9 more than the second number. Which equation can be used to find x, the
Art [367]
Let x = first number and y = second number.
The first statement is expressed as
x*y = 713
The second statement is expressed as
x = y + 9
To find x, use the second equation in terms of y, that is y = x - 9. Then substituting it to the first equation yields
x*(x - 9) = 713
