25% of 28 is 7 (28 x 0.25)

1\tfrac{2}{5} \div \frac{8}{9}<br> 1 5/2 ÷ 9/8

Alexandra [31]

Answer:

Step-by-step explanation:

What you wrote below the top line and the bottom line are not the same thing.

I think you really want the second line, but one can't be sure.

(1*2 + 5)/2 div (9/8)

7/2 // 9/8

7/2 * 8*9

7*8/18 = 56/18 = 28/9

If you really do want the top line (the latex) it is different.

1 2/5 div (8/9) Is there such a thing as tfrac? I didn't know this but there is.

(1*5 + 2)5 // (8/9)

7/5 // 8/9 Invert the bottom fraction and multiply

7/5 * 9 / 8

63 / 40

1 23/40

The average of Johnny's two test grades is a 92 what must he get on his 3rd test to raise his average to a 94?

jeka57 [31]

Answer:

Johnny needs to score 98 on third test to raise average to 94

Step-by-step explanation:

Given that average of two tests is 92.

The score of next test has to be found that means there will be a total of 3 tests.

The average will be:

$Avg = \frac{test1+test2+test3}{3}$

It is also given that he has to raise his average to 98

We have to use the average formula for finding the third value

So,

$94 = \frac{92+92+test3}{3}\\94*3 = 184+test3\\282 = 184+test3\\test3 = 282-184\\test3 = 98$

Hence,

Johnny needs to score 98 on third test to raise average to 94
