liq [111]

Answer:

33.33%

Step-by-step explanation:

well answer choices would help so I know which percentage they want but a 150 increase from 450 to 600 is about 1/3 or 33.33% of 450 and is about 1/4 or 25% of 600 but based on the structure of the question im willing to wager they want 33.33% increase on 450 is 600

Let V be the volume of the pyramid of height 11 whose base is a square of side length 6. Find a formula for the area A of the ho
Rainbow [258]

Answer:

Base area = 36

Volume of the pyramid = 132

Step-by-step explanation:

Volume of a pyramid = Base Area × Height/3

Base area = Length × Length (since base of the pyramid is a square)

Given the side length of the square = 6

Base area = 6×6

Base area = 36

Given height of pyramid =11

Volume of the pyramid = 36×11/3

Volume of the pyramid = 12×11

Volume of the pyramid = 132

Which function has the domain x>or= -11
iogann1982 [59]
I'm assuming this is multiple choice and you forgot to post the answers. I'll take a guess and say it probably looks something like this:
y = \sqrt{x + 11}
Because you can't take the square root of a negative number without getting an imaginary result, resulting in the function having a closed domain limit.
