4x10=40
1/2 x 3 x 6= 9
9x40=360
Answer:

Step-by-step explanation:
The function

gives the mass of the car as a function of the number of passengers in it.
And the function

gives the potential energy of the car as a function of the car's mass.
Now if the height of the ramp is 30 meters, we have


And to find the potential energy as a function of the number of passengers, we just substitute
into
to get:


which gives the potential energy as a function of the number of passengers.
27
you multiply .30 times 90 and you get 27
Answer:
The answer is d = C/pi.
Step-by-step explanation:
To solve this equation for the variable d, we must isolate it on the right side of the equation. It is currently being multiplied by pi, so to reverse this action, we should divide both sides of the equation by pi.
c = (pi) * d
c/pi = pi/pi * d
c/pi = d
d = c/pi
Therefore, the answer is d = C/pi.
Hope this helps!
