A washer machine is filling up with water at a constant rate 3/4 of a gallon and 1/5 of a minute. Don calculated the unit rate to be 3/20 of a gallon per minute what did he do wrong

The unit rate would be

(3/4 gal) / (1/5 min)

because the machine is filled with 3/4 gal of water in 1/5 of a minute. Do the arithmetic to get the unit rate of

(3/4 gal) / (1/5 min) = (3/4 • 5) gal/min = 15/4 gal/min

Don's mistake was to multiply 3/4 by 1/5 to get 3/(4•5) = 3/20, but he should have divided by 1/5 instead.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
