Answer:

17.54  I<u><em>f i can get brainliest that would be great</em></u>

Step-by-step explanation:

to help you next time:

You can find 10% of your bill by moving the decimal one place to the left.  If 26.50 is 100% then 10% is 2.65.  Since 20% is 2 times 10%, 20% of the bill is 2.65 + 2.65 = 5.30.  Now you know the tip you could leave ranging from poor to good, $2.65 to $5.30.  To find 15%, halfway in between, we know 15% is 10% plus 1/2 of 10% (5%).  2.65 plus about 1.30 is 3.95.

Now you have

10% is 2.65 - by moving decimal 1 place left

15% is 3.95 - 10% + 1/2 of 10%

20% is 5.30 - 10% * 2

Answer:

$17.54

Step-by-step explanation:

Change the percentage to a decimal by dividing it by 100

20/100 = 0.2

Then multiply it by the cost

87.70(0.2) = 17.54

Oil is pumped continuously from a well at a rate proportional to the amount of oil left in the well. Initially there were 3 mill
abruzzese [7]

Answer:

V' = -0.11552 *V\\= -0.11552(1.8)\\ \\=-0.20794 million per year

Step-by-step explanation:

Given that oil is pumped continuously from a well at a rate proportional to the amount of oil left in the well. Initially there were 3 million barrels of oil in the well; six years later 1,500,000 barrels remain.

i.e. if V stands for volume of oil, then

V' =kV\\dv/V= kdt\\ln V = kt+C\\V = Ae^{kt}

To find A and k

V(0) = A = 3 million

Hence V = 3e^{kt}

V(6) = 1.5

i.e. 1.5 = 3e^{6k}\\ln 1.5 =ln 3 +6k\\k = -0.11552

V(t) = 3e^{-0.11552t}

a) Using the above value of k , we have

V' = -0.11552 *V\\= -0.11552(1.8)\\ \\=-0.20794 million per year.
