Answer:
22 laps
Step-by-step explanation:
Clara wants to run 5 1/2 miles, and the track is only 0.25 miles long. This is a fairly easy question, you just need to figure out how many times 5 1/2 goes into 0.25, because she wants to run that amount of miles (I could never run that much).
I hope that answers your question so you understand, and I hope you have a great rest of your day! :)
Money to be spent per day <$100
To rent a car:
Minimum amount per day= $45
Amount per mile= $0.25
Hence amount spent depends on distance travelled.
If distance travelled= x; fee for travel= 0.25x
Hence finally we need the fare to be less than $100
And fare is $45+0.25x
So the final inequality is 0.25x+45<100.
Hope it helps.

Answer:
Step-by-step explanation:
From conservation of energy, net work done on the box is equal to the change in kinetic energy of the box. This is written mathematically as:
1/2mvf^2 - 1/2mv^2 = mgdsintheta + (-umgdcostheta)
Where Vf= final velocity of box
V = initial velocity of box
d= distance travelled by the box
U= coefficient of kinetic friction
Theta= angle between the edge of the roof and the ground
-1/2(2.5)V^2= (2.5×9.8×5.5×Sin20° ) + (-(0.54)×9.8× 5.5× cos20°)
-1.25V^2= 46.09 + (-68.38)
-1.25 V^2 = -22.29
V^2 = -22.29/-1.25
V^2 = 17.83
V = Sqrt(17.83)
V = 4.22m/s
