A pencil costs $0.45, an eraser costs $0.30, and a pencil sharpener costs $0.30. What is the cost of 3 pencils, 2 erasers, and 1
alexandr1967 [171]

Hi!

We know the prices of one pencil, one eraser and one pencil sharpener, which are $0.45, $0.30 and $0.30, respectively. Given that, we will find the cost of 3 pencils, 2 erasers and 1 pencil sharpener like this:

3 * 0.45 + 2 * 0.30 + 1 * 0.30 = 1.35 + 0.60 + 0.30 = 2.25

The cost of 3 pencils, 2 erasers and 1 pencil sharpener is $2.25.

Hope this helps!

Please Help!! The line plot shows the length of insects in inches that were collected, how much longer is the longest insect tha
Dmitry [639]

Answer:

D

Step-by-step explanation:

So here we have a line plot that shows lengths of insects and the quantity of insects that fits the description.

For instance, there are 4 Xs for 1/8. This means that there are four insects that are 1/8 inches long. Likewise, there is only 1 X for 7/8. This means that are is only one insect that is 7/8 inches long.

To find out how much longer is the longest insect than the shortest insect, we simply need to subtract the shortest into the longest.

The longest insect we have is the lone insect who is 7/8 inches long.

And the shortest insects we have are the four insects who each measure 1/8. However, we only need 1.

So, subtract:

\frac{7}{8} -\frac{1}{8}

Combine fractions with common denominators:

=\frac{7-1}{8}\\

Subtract:

=\frac{6}{8}

The answer is D.
