Answer:
36 inches.
Step-by-step explanation:
Write the rectangles as ratios.
First= 10:12
Second= 30:x
You can see that the second is 3 times as large as the first. Therefore, the second height must be 12*3. 12*3=36
Answer:
Her answer is not reasonable. Her average is 83.
Step-by-step explanation:
Add all of her test grades together (96+82+78+76=332)
To find the average, you need to add all test grades she got and then divide the sum by the total number of numbers added (in this case, we added 4 tests together, so we need to divide by 4)

So she added wrong and forgot to divide by the total number of tests.
