3/5 of 30 guys I need help calling upon all the g's out there Also I'll give

18 guys !

Step-by-step explanation:

To solve this problem I used cross multiplication and division ;

First you will have to set up the proportions so they match

Since we don't know what x is, we have to solve for it by using cross multiplication

3 x 30 = 90

90 / 5 = 18

I hope this helped ! :))

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.

answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74
