Bill joins a local gym that requires him to pay a membership fee of $200 in order to join in addition to a $15/month gym fee while Sue's gym is a little less expensive to join at only $75 in addition to a $25/ month gym fee. You are to use the slope formula in order to show the cost for each at the end of 12 months. You must have a minimum of 4 points on each graph! Next: Who ended up spending the most at the end of the year to go to the gym?

113.1

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.

answer is (b.
