The Pharaoh builds a square pyramid which is 20 feet on one side, with a height of 36 feet. Find the pyramid's volume. ANSWERS: 720 ft3 560 ft3 240 ft3 4,800 ft3

Answer

4800 ft3

Step-by-step explanation:

Formula for volume of a pyramid is 1/3*base*hight

because you do 20*20=400ft2 for the base

Then you times 36 (the hight) by 1/3 and get 12

Then you do 400*12=4800ft3 theres your answer

hope this helps

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
