Answer: $13200

Step-by-step explanation:

If 100 square feet of roofing is installed for a cost of $1,200

1,100 square feet would cost $Z (let the unknown cost be Z)

i.e 100 ft^2 = $1,200

1100 ft^2 = $Z

Hence, to get the value of Z, cross multiply

Z x 100 = 1200 x 1100

100Z = 130000

Divide both sides by Z

100Z/100 = 1320000/100

Z = $13200

Thus, $13200 is the cost to have 1,100 square feet of roofing sheet installed

**Answer:**

x = 4

**Step-by-step explanation:**

2(4x-12)=8

4x-12=4

4x=16

x=4

First of all, this is not an observational study, but an experiment, since we have two groups and one of the two groups is manipulated or treated. In an observational study the subjects are only observed.

Second, the students did not choose their groups - so we can't choose the last answer.

Therefore the correct answer is:

This is an experiment because a treatment was applied to a group.

**Answer: **<em>I believe the answer would be 16 divided 7, so you find the answer to that then you put the positive and the negative of that number for the answer. </em>
