Answer:

The cost of 7.5 lbs of chopped walnuts is $25.875

Step-by-step explanation:

we are given

It costs $3.45 to buy lb of chopped walnuts

so,

1 lb of chopped walnuts = $3.45

now, we can multiply both sides by 7.5

7.5\times 1lb=7.5\times 3.45

so, we get

7.5 lbs of chopped walnuts = $25.875

So, the cost of 7.5 lbs of chopped walnuts is $25.875

2. Write two numbers that are opposites and each more than 6 units away from 0.
Yuki888 [10]

Answer:

-7, 7

Step-by-step explanation:

Opposites are basically two numbers that are at different sides of the number line. For example, -2 and 2 are opposites because they are the same distance away from 0 on a number line making them opposites. To make an opposite just take a positive number, and then add a negative to it. (8, -8)

A clerk at Agency Y has determined that at speeds of 25 pages per minute it is typical for 3 out of every 100 pages she photocop
nalin [4]

Answer:

180 pages

Step-by-step explanation:

Since her photocopy session is 25 pages per minute, the total number of pages photocopied in 4 hour session can be calculated as;

number of pages = time × speed

                                 = (4 × 60) × 25

                                 = 240 ×25

                                 = 6000 pages

Thus, number of pages photocopied in 4 hours is 6000.

For every 100 pages, 3 would contain some type of printing error. The number of pages she expect with printing error during 4 hour session can be determined as;

           = \frac{6000}{100} × 3

           = 60 × 3

           = 180 pages

The expected number of pages with printing error during 4 hour photocopying session is 180 pages.
