Meal=$40 find the total cost​
zepelin [54]

Answer:

Step-by-step explanation:

You want to leave a 15% tip on a meal that cost $48.

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $48 meal cost is.This is always done by multiplying 0.15 by $48.00, or

0.15 x $48.00=$7.20.

So, the amount of tip you are going to leave is $7.20.

This makes the total cost of your meal (to write on your charge slip or other payment)

$48.00 + $7.20 = $55.20.

i hope this may come to use to your rude a    s    s

Simplify the expression the root of negative sixteen all over the quantity of three minus three i plus the quantity of one minus
aliya0001 [1]
The first step is to multiply the fraction by (3 +3i) / (3 +3i) to delete the i terms from the denominator:

\frac{ \sqrt{-16} }{3-3i} . \frac{3+31}{3+3i} +1-2i=  \frac{4i(3+3i)}{9+9} +1-2i= \frac{12i-12}{18} +1-2i=

\frac{12i-12+18-36i}{18} = \frac{6-24i}{18} = \frac{1}{3} - \frac{4}{3} i
