Answer:
The total cost of the meal is $58.56.
Step-by-step explanation:
The question is asking for problem solving with percentages. In order to multiply by a percentage, we must first convert the percentage to a decimal by diving the percent by 100. Since the Hu family is going to leave a 15% tip on the pre-tax amount of $48, we will need to multiply 48 x .15 = $7.20. The Hu family must also pay a 7% sales tax on the cost of the meal. In order to find the cost of the meal, including tax, we take the price of 48 x 1.07 = $51.36, which would be the original cost plus an additional 7% tax. Lastly, we would need to include the tip to the post-tax total: $51.36 + $7.20 = $58.56.

Answer:
(2,3)
Step-by-step explanation:
Part (a)
We'll use the distance formula.
The diameter is exactly 
units long which approximates to roughly 10.2956 units. Round that decimal value however your teacher instructs.
========================================================
Part (b)
We divide the diameter in half to get the radius.
Therefore, the radius is exactly 
units long which is approximately 5.1478 units.
