The area was originally 3*5, or 15 cm^2.
When the sides were enlarged, they were all multiplied by 3. The new sides are 3*3, or 9, and 5*3, or 15.
The new area is 9*15, or 135 cm^2.
If you divide 135, the new area, by 15, the original area, you get 9. So, the area increased by a factor of 9.
Answer:
whats the question
Step-by-step explanation:
1245 divide by 2 is 622.5 I did this on a calculator.
Answer: False
Step-by-step explanation: To find the mean time add all the times and divide by the amount of times you have, which is 9.
0 + 15 + 30 + 90 + 105 + 120 + 45 + 60 + 75 = 540 total minutes spent.
Now divide 540 by 9 to get the mean time. 540 divided by 9 = 60.
So the mean is 60 minutes, not 75 minutes.
Therefore the statement below is False.
The missing side is 17 and rounded it is 20
