Which expression converts startfraction pi over 4 endfraction radians to degrees?
startfraction pi over 4 endfraction times 180 degrees
startfraction pi over 4 endfraction times startfraction 180 degrees over pi endfraction
startfraction pi over 4 endfraction times startfraction pi over 180 degrees endfraction
startfraction pi over 4 endfraction times pi

StartFraction pi Over 4 EndFraction times StartFraction 180 degrees Over pi EndFraction.

Step-by-step explanation:

We know the relation between radian and degree is that, π radians = 180°.

Then we have to calculate the degree that is equivalent to radians.

Now, using the unitary method, we can calculate the degree value.

Therefore, radians is equivalent to .

So, it is StartFraction pi Over 4 EndFraction times StartFraction 180 degrees Over pi EndFraction. (Answer)

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
