Ending time: 10:08 am elapsed time: 30 minutes

Answers

Answer:

Hence, beginning time is:

9:38 a.m.

Step-by-step explanation:

We know that:

" Elapsed time is the time or difference between a beginning time and an ending time "

Here we are given that the ending time is:

10:08 a.m.

and elapsed time is:

0:30 minutes.

This means the beginning time will be :

ending time - elapsed time.

Hence on counting back 30 minutes from 10:08 am we get the beginning time as:

9:38 a.m.

We have to subtract 30 minutes from 10:08 am, then the elapsed time will be 9 hours 38 minutes.

What is subtraction?

It simply means to deduct something from the object or number of group, place, etc. Subtraction means to take away from the group or a number of objects.

Ending time: 10:08 am elapsed time: 30 minutes. Then the time will be

We know that elapsed means before 10:08 am. So we have to subtract 30 minutes from 10:08 am. Then we have

\begin{matrix} & 10 & : & 08 \n- & 00 & : & 30 \n& \overline{09} & : & \overline{38}\end{matrix}\n

Then the time will be 09:38 am.

Stefan measured a weight of a package as 15.375 pounds. The actual weight of the package is 15.125 pounds.What is the approximate percent error Stefan made in measuring the weight of the package?write ur answer to the nearest percent.
Part b
Alexis measured the weight of the same package and got the same percent error as Stefan. Alexis and Stefan both measured different weights of the package.
What weight in pounds did Alexis measure. Explain how u know

Answers

The formula is |(estimated - exact ÷ exact) x 100|

((15.375 - 15.125) / 15.125) x 100 = 1.652892562 
You might want to round that number a 'lil 

Part 2: She got 14.875 b/c with the equation there are no negative percentages, so that means that since 15.375 - 15.125 = 0.25, than 15.125-0.25 = what she got.
