Answer:
18 inches
Step-by-step explanation:
Volume of a pyramid is:
V = ⅓ Ah
where A is the area of the base, and h is the height of the pyramid.
The base is a rectangle. Area of a rectangle is width times length, so:
V = ⅓ wlh
Plugging in values and solving:
1512 = ⅓ w (21) (12)
w = 18
The width of the base is 18 inches.
Answer:
m = 2, c = - 1
Step-by-step explanation:
Using the point (1, 1), substitute x = 1, y = 1 into the equation
m + c = 1 → (1)
Using the point (2, 3), substitute x = 2, y = 3 into the equation
2m + c = 3 → (2)
Subtract (1) from (2) to eliminate c
(2m - m) + (c - c) = (3 - 1) ← simplify
m = 2
Substitute m = 2 into (1) for corresponding value of c
2 + c = 1 ( subtract 2 from both sides )
c = - 1
The answer is 4.125. 65/8 is 8.125. 8.125-4 is 4.125 or 4.1 to the tenths place and 4.12 to the hundredth.
