The diagram shows the ratio of teeth on the larger and smaller gears of Nash's fishing reel.

A tape diagram showing 6 parts labeled "larger gear" and 1 part labeled "smaller gear"

Based on the ratio, how many teeth are on the smaller gear if there are 72 teeth on the larger gear?

There are 12 teeth on the smaller gear if there are 72 teeth on the larger gear.

Step-by-step explanation:

I had the same question on khan

answer: 88

step-by-step explanation:

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.
