<span>First you take 3/4 of the tank (18000 gallons)
then you have to divide that by 40 to find out how many minutes it will take to get it.
the answer would be 450 minutes</span><span>i hope that thiss helps you out, have an amazing day!!</span>
The answer is c bc I just know
Answer:
a) weight of the car = 2816,1 lbs
b) 2773 lbs
Step-by-step explanation:
The equilibrium force is 490 lbs. That force keep the car at rest, then
∑ Fy = 0 and ∑Fx = 0
Forces acting on the car:
The external force 490 lbs
weight of the car uknown
Normal force
sin∠10° = 0,174
cos∠10° = 0.985
∑Fx = 0 mg*sin10°- 490 = 0 ∑Fy = 0 mg*cos10° - N = 0
mg*0,174= 490
mg = 490 / 0,174
mg = 2816,1 lbs
weight of the car = 2816,1 lbs
The Normal force
mg*cos10° - N = 0 2816,1 * 0,985 = N
N = 2773 lbs
Then equal force in magnitude and in opposite direction will car exets on the driveway
A(b + c) = a*(b + c) = a*b + a*c
You must multiply individual terms and see what it would equal
