Step-by-step explanation:
To find the cost of the tip, we need to find 120% of 39.50.
120% = 100% (order) + 20% (tip)
Let's use fractions. 39.50 can be put over 1, and 120 can be put over 100.
<u>Equation:</u>
<u />

<u />
<u>Divide 4740 and 100 by </u><u>100</u><u>:</u>
<u />
The total cost of the food is $47.40.
Answer:
b) √29
Step-by-step explanation:
Given: The origin is (0, 0), the point P is (2, -5).
We need to use the distance formula.
Distance formula = 
Here x2 = 2, x 1 = 0, y1 =0, y2 = -5
Distance = 
= 
= √(4 + 25)
= √29
The answer is b) √29
