If 72 is 120% of a number, what is 80%<br> of this number?
cupoosta [38]

Answer:

60

Step-by-step explanation:

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

STEP 172 = 120% × Y

STEP 272 =  

120

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 120 we will arrive at:

STEP 3Y = 72 ×  

100

120

STEP 4Y = 72 × 100 ÷ 120

STEP 5Y = 60

Finally, we have found the value of Y which is 60 and that is our answer.

You can easily calculate 72 is 120 percent of what number by using any regular calculator, simply enter 72 × 100 ÷ 120 and you will get your answer which is 60

The number of milligrams Dh of a drug in a patient's bloodstream h hours after the drug is injected is modeled by the following
hodyreva [135]

We assume you intend

D(h)=35e^{-0.15h}

You want to evaluate this function for h=0 and h=8.

D(0)=35e^{0}=35\\D(8)=35e^{-0.15\cdot 8}\approx 10.54

The amount injected was 35 milligrams; 8 hours later 10.54 milligrams remained.
