A, c, and d are the three possible options he has.
The answer is the letter D
Answer:
h = 6 units
Zhang major error is that he did not express the formula for finding the volume of a square base pyramid properly well. The formula was suppose to be 1/3 × base area × height. He omitted the 1/3.
Step-by-step explanation:
The square base pyramid has a base length of 9 and width of 9 . It is a square base pyramid so definitely the length of the base will be equal. The volume of the square base pyramid is given as 162 .
The formula for the volume of a square base pyramid is represented as follows.
volume = 1/3Ah
where
A = base area
h = height
volume = 1/3Ah
Base area = L²
Base area = 9² = 81
volume = 162 units²
volume = 1/3 × 81 × h
162 = 1/3 × 81 × h
162 = 27h
divide both sides by h
h = 162/27
h = 6 units
He omitted the 1/3 for the formula of the volume of a square base pyramid.
The equation for point-slope form is:
(y - y sub 1) = m * (x - x sub 1)
So, we enter the point we have and the slope we have:
(y - 5) = 3 * (x + 1)
The answer is the third choice.
Answer:
Presley is the fastest
d= 55t
Step-by-step explanation:
d= rt
Divide by t
d/t =r
so we can find the rate
Braylon
50 miles per hour
Kiko
rate = distance/ time
= 405 miles / 9 hours
= 45 miles per hour
Presley
rate = distance/ time
= 385 miles/ 7 hours
= 55 miles per hour
Presley is the fastest
d =rt
d = 55 t
Remember t >=0 since it is time
