Let's go through each answer.

A.

Answer: The amount left over was 4.05 L.

Estimation: 3.15 + 4.75 is about 7.

7 L – 4 L = 3 L

The amount left over was about 3 L.

This is incorrect because 3.15+4.75 is closer to 8 than 7.

B.

Answer: The amount left over was 3.95 L.

Estimation: 3.15 + 4.75 is about 8.

8 L – 4 L = 4 L

The amount left over was a little less than 4 L.

This is correct because 3.15+4.75 is close to 8 and to find the amount left over you do have to subtract.

The correct answer is B.

Answer: The amount left over was 3.95 L.

Estimation: 3.15 + 4.75 is about 8.

8 L – 4 L = 4 L

The amount left over was a little less than 4 L.

How many 2-inch segments are there in 12 ft.?<br> O A. 6<br> O B.24<br> O C. 10<br> OD.7
Scrat [10]

Answer:

72 segments

Step-by-step explanation:

First we convert 2 inches to feet units:

We know that one foot equals 12 inches

Then we use this conversion factor as shown below.

2\ in*\frac{1\ ft}{12\ in}=\frac{1}{6}\ ft

To know how many \frac{1}{6}\ ft  segments there are in 12 ft, we must divide 12 ft ÷ \frac{1}{6}}\ ft

So:

\frac{12\ ft}{\frac{1}{6}\ ft}= 12*\frac{6}{1}=12*6=72\ segments

In 12 ft there are 72 2-inch segments

Common ratio = 6250/15625 = 2500/6250 = 0.4

an for GP = ar^(n - 1)

= 15625*(0.4)^(n - 1)
