Question

5) 13 candy bars weigh 26 ounces. What is the weight of 35 candy bars?6) A machine can produce 6 yards of fabric in 2 minutes. How many yards of farcan it produce in 1 hour?

Answer 1

Step-by-step explanation

If 13 candy bars weight 26 ounces then the weight of a single bar is given by taking the total weight and diviving it by the number of bars so we must perform the following calculation:

`\frac{26\text{ oz}}{13\text{ bars}}=2\frac{\text{oz}}{\text{bar}}`

So each bar weights 2 ounces. Then the weight of 35 candy bars is:

`35\text{ bar}\cdot2\frac{\text{oz}}{\text{bar}}=70\text{ oz}`

We know that the machine produces 6 yd in 2 minutes. Then the production of fabric in yards per minute is given by:

`\frac{6\text{ yd}}{2\text{ min}}=3\frac{\text{yd}}{\text{min}}`

There are 60 minutes in an hour so if we want to know how many yards of fabric are produced by the machine in an hour we must multiply the yards produced in a minute by 60:

`3\frac{\text{yd}}{\text{min}}\cdot60\text{ min}=180\text{ yd}`Answers

Then the answers are:

5) 70 ounces

6) 180 yards
