In this problem, you would just divide your test results by the maximum test points you can get. 
60 divided by 75 is 0.8, which is 80%, which is probably a grade I will never see in my life :P
Hope I helped!

So he got 60/75. let's divide it by 15!
which is then 4/5. and if you multiply that by 2 you have a base of 10!---> 8/10 now that's 80%

Oil leaked from a tank at a rate of r(t) liters per hour. the rate decreased as time passed, and values of the rate at two hour
Galina-37 [17]
The given data is
t, h:            0     2     4     6     8   10
r(t), L/h:   8.6  7.9  6.8  6.4  5.7  5.3

The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.

The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.

The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L

The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L

Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L

Ivan makes 340 per week. how much would he make per week if he got a 5% raise
lys-0071 [83]
Finde 5%
percent means parts out of 100 so 5%=5/100=1/20
find 1/20 of 340 and add that to 340
'of' in math translates to multiply
1/20 times 340=340/20=34/2=17
add that to 340
340+17=357

he would make 357 a week
