Answer:

<h2>A) 1 inch drawing, 3 feet actual.</h2>

Step-by-step explanation:

The given scale is

\frac{1}{4}in=1ft

That is, each foot equals one quarter of an inch. In other words, 1 inch equlas 4 feet, because

\frac{1}{4}in=1ft\\ 1in=4ft

That means, 1 inch drawing represents 4 feet actual. Now, let's see which choice doesn't have this same proportion.

You can observe that option A has a proportion where 1 inch drawing equals 3 feet actual, which is not the same proportion as the given, because the given one is 1 inch drawing equals 4 feet actual.

Therefore, the right answer is A.

Oliga [24]

Answer:

f(g(-6)) is equal to 60

Step-by-step explanation:

We can simply solve this by first plugging -6 into function 6, and then applying function f to the result of that.

f(g(-6))\\= f(1 - \frac{2(-6)}{3})\\= f(1 - \frac{-12}{3})\\\\= f(1 + 4)\\= f(5)\\= 3(5)^2 - 15\\= 3 * 25 - 15\\= 75 - 15\\= 60

Makovka662 [10]

Answer: 64% of garbage was plastic over there when he was collected garbage.

Step-by-step explanation:

Since we have given that

Total amount of garbage collected by them = 25 pounds

Total amount of garbage which consisted of plastic = 16 pounds

Percent of the garbage was garbage is given by

\frac{ plastic}{total}\times 100

=\frac{16}{25}\times 100\\\\=16\times 4\\\\=64

Hence, 64% of garbage was plastic over there when he was collected garbage.
