Answer:
Use photo math, it will explain it all in different forms
We use the Work formula to solve for the unknown in the problem which is W = F x d. First, we solve for the Net Force acting on the car. The Net Force is the summation of all forces acting on the object. For this case, we assume that Friction Force is negligible thus the Net Force is equal to:
F = mgsinα in terms of SI units and in terms of english units we have F = m(g/g₀)(sin α) where g₀ is the proportionality factor, 32.174 ft lb-m / lb-f s²
F = 2500 (32.174/32.174) (sin 12°) = 519.78 lb
W = Fd = 519.78 lb (400 ft) = 207912 ft - lb or 20800 ft-lb
Answer:
26 mm
Step-by-step explanation:
A=wl= 42 mm²
l=7, w= 42/7= 6 mm
P=2(l+w)= 2(7+6)= 26 mm
To find the mean you add all the numbers and divide by how many numbers there are so in this case 2+3+4+4+6= 19, there are 5 numbers so divide 19/5
Answer:
Answer is A - $43.40
Step-by-step explanation:
For 115 minutes, we would be in the middle territory and so will need to use the middle equation:
