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?

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
