2/3 of a hippo's life is spent under water, the rest of their life out of water is separated into grazing, sleeping, and socialising in the ratio of 4 : 7 : 1. the average life of a hippo is 45 years, how long will it spend doing each of these activities?

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

could u provide us some answer choices or hmm idk maybe a table for us to anser with ? ?
