Michael’s weight can be represented by the expression 72x^5. al’s weight can be represented by the expression 9x^7.

Part A) The ratio is

Part B)

Part C) ----> The answer change

Step-by-step explanation:

Let

a------> Michael's weight

b----> Al's weight

we have

Part A) What is the ratio of Michael's weight  to Al's weight

we know that

substitute the values

Part B) Simplify the ratio from part A)

we have

we know that

substitute

Part C) If the exponents in each expression were negative, instead of positive, would that change your answer for part b?

If the exponents in each expression were negative

then

the expression will be

we know that

substitute

therefore

The answer change

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

36/60

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
