Correct question is;
Peter wants to make four necklaces that are the same way. He asked his friends to cut the string for the necklace 15 paper clips long. Would all the lengths be the same? Explain your think
Answer:
No, the lengths would not be the same. This is due to the fact the the paper clips could be in different sizes.
Step-by-step explanation:
We are told that he wants to make four necklaces that are the same way and that he told his friends to cut the string for the necklace 15 paper clips long.
Now, we are not told the sizes of the paper clips and we know that paper clips come in different sizes. Thus the paper clips in which the strings are cut could be in different sizes. Therefore, the lengths wouldn't be the same due to that.

Answer:
Below in bold.
Step-by-step explanation:
Amount originally in the cup = amount she drank + amount remaining
= 17 * 4.5 + 148.5
= 76.5 + 148.5
= 225 milliliters.
The time she takes to drink the 148.5 mL = 148.5 / 4.5
= 33 seconds.
So time to drink it all = 17 +33 = 50 seconds.
Answer: it will take the faster computer 15 minutes to do the job on its own.
Step-by-step explanation:
Let t represent the number of minutes it will take the faster computer to do the job on its own. It means that the rate at which it does the job per minute is 1/t
If it takes the slower computer 30 minutes to do the job on its own. It means that the rate at which it does the job on its own per minute is 1/30
By working together, they would work simultaneously and their individual rates are additive. Working together it takes two computers 10 minutes to send out a company's email. It means that the rate at which both computers work together per minute is 1/10 Therefore,
1/t + 1/30 = 1/10
Cross multiplying by 30x, it becomes
3x = x + 30
3x - x = 30
2x = 30
x = 30/2
x = 15 minutes
The answer to the first question is 30.
