What percent of 25 is 14?
a. part-
b. total -
c. percent -
d. write and solve the proportion

a. part -  14

b. total -  25

c. percent - x%

d. 100/25 = x/14; 56%

Step-by-step explanation:

What percent of 25 is 14?

a. part - 14

b. total -  25

c. percent - x%

d. The total is 100% and 25.

The part is x% and 14.

100% is to 25 as x% is to 14.

100/25 = x/14

4 = x/14

x = 56

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.
