geniusboy [140]

Answer:

(a)s^2\\(b)162=2s^2\\(c)s=9$ ft

Step-by-step explanation:

(a)Base Area

Side length of square base=s

Area of a Square of side length s=s^2$ ft^2

(b)

  • Height =6 ft
  • Volume=162 $ ft^3.

Volume of a Pyramid=\frac{1}{3}X$Base Area X Height

Substituting the given values, we have:

162=\frac{1}{3}Xs^2 X 6\\\\162=2s^2

(c)Solving the equation derived from (b)

162=2s^2\\$Divide both sides by 2\\s^2=81\\s^2=9^2\\s=9$ ft

Solving this equation shows that s =9 ft.

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains liters of natural oil for every liters of synt
Aleonysh [2.5K]

Answer:

You didn't put any numbers, but I'm going to assume it's 5 liters of natural oil for every 8 liters of synthetic oil and you're asking in order to make 936 liters of petrolyn oil, how many would need to be synthetic. In that case the answer would be 576

Step-by-step explanation:

( natural oil ) / ( synthetic oil ) = 5/8

Let x = liters of synthetic oil needed

936 - x = liters of natural oil needed

5/8=936-x/x

Multiply both sides by 8x

5x=8(936 - x)

5x=7488 - 8x

13x=7488

x=576
