36 is 75 percent of what

Marta_Voda [28]

36 = 75% of what?

36 = 75% of x

36 = 0.75x

0.75x = 36

x = 36/0.75

x = 48

Therefore 36 is 75 percent of 48

Hope this explains it.

Answer:

${ \underline{ \sf{\int\limits^2_1 {x^{2}-8x+8 } \, dx} \: = \: - 1}}$

Step-by-step explanation:

${ \tt{\int\limits^2_1 {x^{2}-8x+8 } \, dx}} \\ \\ = { \tt{[ \frac{ {x}^{3} }{3} - 4 {x}^{2} + 8x ] {}^{2} _{1}}}$

Substitute x with the limits:

$= { \tt{( \frac{ {2}^{3} }{3} - 4( {2)}^{2} + 8(2)) - ( \frac{ {1}^{3} }{3} - 4( {1)}^{2} + 8(1)) }} \\ = { \tt{( \frac{8}{3} - \frac{11}{3} )}} \\ \\ = { \tt{ - 1}}$

The square root of 12 is irrational.<br><br> True<br> False

dalvyx [7]

True.

The square root of 12: √12 = 3.464101......

This continues indefinitely and can not be represented as a ratio of two integers.

So it is not rational, that is irrational.
