Answer: 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

Please explain the answer..

Answers

time and a half mean
example, if he work for 1 hour normal, then he get 1 hour pay
but time and a half, is if he works 1 hour overitme, he gets paid for 1.5 time
double time is work 1 hour, get paid 2 hours

basically, multiply all normal hours by 1, multpliy al overtime hours by 1.5 and multiply al holiday hours by 2

40 hours normal
9 hours overtime
12 hours holidy
40*1=40
9*1.5=13.5
12*3=24
add up
40+13.5+24=77.5 hours counted

now 11 per our
11 times 77.5=852.50

What is 20% off of £1.85? ^_^

Answers

$p\%=(p)/(100)\n\n20\%=(20)/(100)=0.2\n\n20\%\ of\ \£1.85\ is\ 0.2\ *\ \£1.85=\£0.37$

£1.85 ________ 100 %
x ________ 20 %

100x = 20 . 1,85
100x = 37
x = 37 / 100
x = 0,37

is £0,37 !

What is the solution to the linear equation?

Answers

The answer is p=1

First you have to subtract 2/5 on both sides to get p=2/5x+3/5p.

Then subtract 3/5p on both sides to get 2/5p=2/5.

Then you divide by 2/5 on both sides to isolate p and you get 1 :)
