The area of a circle is pi times the radius squared
Answer:
$22.43
Explanation:
We can start by finding the amount that they should tip. The total bill is $78, so we should take 15% of 78 and add it to the total.
0.15 * 78 = 11.7
78 + 11.7 = 89.7
This means that the total cost of the bill, with a tip, is $89.70.
Since there are 4 people, we have to split this total into 4 if they all want to pay equally.
89.70 / 4 = 22.425 = $22.43 !
Hope this helps
You add half of the coefficient of x and square it.
What you do on one side,you must do it on the other.
I believe the answers are C. Acute (all angles less than 90 degrees) and E. Scalene (all 3 sides different values).
