Answer:
3 hours
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s ----> the speed in mph
d -----> the distance in miles
t ----> the time in hours
x ----> distance traveled by Daisy to the meeting point
60-x ----> distance traveled by Sally to the meeting point
so
Solve for d
<em>Distance traveled by Daisy to the meeting point</em>
we have
substitute
----> equation A
<em>Distance traveled by Sally to the meeting point</em>
we have
substitute
----> equation B
substitute equation A in equation B
solve for t
Answer:
inches or approximately 5.97 inches
Step-by-step explanation:
Use the cone volume formula: V = r²
The diameter is 8 inches, so the radius will be 4 inches.
Plug in the radius and volume, and solve for h
V = r²
100 = (4²)(
)
100 = 16
Divide each side by 16
=
Cross multiply and solve for h:
4h = 75
h =
So, the cone's height is or approximately 5.97 inches
