What is 3 hours to 45 minutes in the simplest ratio?

= 3 hours : 45 minutes

= (3 hours)/(45 minutes)

We know, 1 hour = 60 minute, 3 hours = 3 × 60 minutes = 180 minutes,

= (180 minutes)/(45 minutes)

= 180/45

= 4/1

= 4 : 1

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.
