Answer:
Cheryl is correct.
Step-by-step explanation:
Cheryl solved a problem : 84 ÷ 0.01 = 8,400.
This is absolutely right.
When we divide any whole number with the divisor having decimal, we change the divisor to a whole number before performing the division.
To do this, we multiply both the numbers (divisor and dividend) by the same power of 10, until the divisor is a whole number.
= 
to make divisor a whole number we will again multiply both the numbers by 10.
= 
= 8,400
Now answer would be 8400.
Therefore, Cheryl is correct.

Answer:
<h2>z = 5</h2>
Step-by-step explanation:
-0.25z= -1.25
Convert the decimals to improper fractions
That's
<h3>
</h3><h3>
</h3>
So we have
<h3>
</h3>
Multiply through by 4
We have
- z = - 5
Divide both sides by - 1
the final answer is
<h3>z = 5</h3>
Hope this helps you
Okay, so I know that you either multiply the volume of a cone by 3 to get the cylinders volume, or you divide it. I think you multiply it. Just remember, the rule is to multiply the volume of a cone by 3, to get the cylinder volume with the same measurements. So 15 x 3.
We will represent the length of the rectangle as 
and the width as 
.
From this problem, we can say 
. We can also deduct an equation from the second sentence:
(from substitution)
Using this value for , we can find :
The length of the rectangle is 23 cm and the width of the rectangle is 18 cm.
