CosA=(21^2+23^2-25^2)/2*21*23
cosA=345/966
A=cos^-1(345/966)
A=69.08
Answer:
any number that isn't 8 or above it
Step-by-step explanation:
Answer:
A = 1/2 B H area = 1/2 base X height
B = 2 A / H = 2 * 99 / 12 = 16.5 cm
dA / d t = 1/2 * (B dH / dt + H dB / dt)
dB / dt = (2 dA / dt - B dH / dt) / H
dB / dt = (2 * 1.5 cm^2 / min - 16.5 cm * 2 cm / min) / 12 cm
dB / dt = (3 - 33) / 12 cm/min = -2.5 cm/min
Answer:
30 ft of dirt.
Step-by-step explanation:
We want to know the volume, or the capacity, of the hole.
The formula for volume is to multiply the length, width, and height.
l x w x h
2 x 5 x 3 = 30
So there is 30 ft of dirt in the hole.
