75.50/78.25 = x/100
Using this proportion, finding x will find the percentage out of 100 that 75.50 is of 78.25
75.5*100=78.25x
x= 7550/78.25 = 96.486%
Or you could just do 75.5/78.25 to get the same answer.
It is called effective interest rate.
For example, you invest in a bond wich pays 5% annual interest rate and it compounds semiannually.
The first semester you win 2.5% over the capital invested and in the second semester you win 2.5% over the capital plus the interested earned in the first semester. Then the effecive interest rate is higher than 5%.
Answer:
3.125 mg/ oz
Step-by-step explanation:
Amount of instant tea = 24 ounces
Amount of green tea = 12 ounces
Caffeine in instant tea = 24/8*30= 90 mg/oz
Also, caffeine in green tea = 12/8*15 =22.5 mg/oz.
Total amount of mixture= 24+12= 36 ounce
Total amount of caffeine in the mixture = 90+22.5 = 112.5 mg/oz
Caffeine per ounce in the final mixture = 112.5 / 36 = 3.125 mg/ oz
Answer:
<u>1.</u> 20 boxes cost $36. The unit rate is 1:1.8 and when you multiply 1.8 by 5 you get 9. If you also multiply 1.8 by 20 you get 36.
<u>2.</u>He completes 12.5 pages in 200 minutes.
