What is the value of x in the equation 4x+8y=40 when y=0.8
GREYUIT [131]
Substitute in 0.8 for y.

4x+8y=40 \\ \\ 4x + 8(0.8) = 40 \\ \\ 4x + 6.5 = 40 \\ \\ 4x = 40 - 6.4 \\ \\ 4x = 33.6 \\ \\ x = 8.4 \\ \\

The final result is: x = 8.4.

Find the surface area of a square pyramid with a length of 5 cm and a slant height of 8cm.
Tems11 [23]
Area of the square base = 5^2 = 25 cm^2
Area of one of the triangular side = 1/2 * 5 * 8 = 20 cm^2 and there are 4 sides
So the surface area  of while pyramid = 4 * 20 + 25 = 105 cm^2

Volume of the cone = (1/3) pi r^2 h
  = (1/3) pi * 5^2 * 8
  =  209.44  ft^2
