Answer:

I think she is incorrect she need to change all the fractions to the same denominators

Step-by-step explanation:

We are going to change all the fractions to 64

9/64 stays the same

5/32 multiply 2    then 10/64

1/16 multiply by 4 then 4/64

1/8 multiply by 8  then 8/64

Now we can order then

5/32 > 9/64 > 1/8 > 1/16 This is the right order

She was wrong.

Answer:

(2) 2,640 ft

Step-by-step explanation:

I'm going to assume that in this question, you are walking 1 full circle around the reservoir. That would mean you need to calculate the circumference of the circular reservoir.

The circumference formula is:

C = ⫪d

C stands for Circumference

d stands for diameter

I will use 22/7 instead of pi, so the formula looks more like this:

C = (22/7)(d)

The diameter is 840 feet, so we will substitute the variable d with 840:

C = (22/7)(840)

You can plug this part into the calculator, but by hand, it'll look something like this:

(22/7)*840 = (22*840)/7

18,480/7 = 2.640

Hope it helps (●'◡'●)
