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.
By definition, the perimeter of the triangle is the sum of its sides.
We must then use the formula of distance between points:
We now look for the longitus for each of the sides:
For L1:
For L2:
For L3:
Then, the perimeter is given by:
P = L1 + L2 + L3
Substituting values we have:
Answer:
the perimeter of triangle ABC is:
