For every 3.3 km rock is buried, the pressure placed upon it increased 0.1 gigapascals. If rock undergoing metamorphosis is buried at 16 km what is the pressure placed on that rock?

Answers

For every 3.3 km rock is buried, the pressure placed upon it increased 0.1 Giga pascals.

We need to find the pressure placed on that rock at 16 km.

Let us divide 16 km by 3.3 first to find the number of 0.1 Giga pascals would be there.

16/3.3.

On dividing 16 by 3.3, we get 4.8485.

In order to find the number the pressure placed on that rock, we need to multiply 0.1 by 4.8485, we get

0.48485 Giga pascals.

Therefore,  if rock undergoing metamorphosis is buried at 16 km, 0.48485 Giga pascals is the pressure placed on that rock.

Cory’s average score after 8 tests is 91%. If he gets a 78% on his 9th test what will his new average be?

Answers

The new average will be 89.55%.

What is an average?

The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.

It is given that,

Average score after 8 tests = 91%.

Therefore, Total score of 8 tests = Average score*Number of tests

Total score of 8 tests = 91*8

Total score of 8 tests = 728

Now, Cory scored 78% in 9th test,

So, Total score of 9 tests = Total score of 8 tests + 78

Total score of 9 tests =  728 + 78

Total score of 9 tests = 806

Hence, Average score of 9 test =  Total score of 9 tests/9

Average score of 9 test = 806/9

⇒ Average score of 9 test = 89.55%

Hence, the new average will be 89.55%.

add all the scores together and the divided by the number of scores there are

8 tests will be 8x91 = 728 

Then add on his latest test result 728+78 = 806 

Now divide by the number of tests (9) 806/9 = 89.55555555 
89.555%
