Audryn left a $12 tip on a $68.73 restaurant bill. What percent tip did she leave? Round to the nearest tenth of a percent.
Fiesta28 [93]
So, if we take 68.73 to be the 100%, what is 12 in percentage off of it?

\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
68.73&100\\
12&p
\end{array}\implies \cfrac{68.73}{12}=\cfrac{100}{p}\implies p=\cfrac{12\cdot 100}{68.73}

seems Audryn is being generous, she probably got the silverware and the maple leaves tablecloth.

A driveway has an area of 96 square feet. The width of the driveway is 8 feet.
Mrrafil [7]

Answer:

12 feet

Step-by-step explanation:

A driveway is rectangular in shape.

Therefore we can calculate the area using the formula;

A = L \times W

From the question;

The area,A=96 feet square

The width, W=8 feet

We substitute this values into the formula to find the length, L.

This implies that

96 =L \times 8

Dividing through by 8.

\implies \frac{96}{8}= \frac{L \times 8}{8}

\implies L = 12

Hence,the length of the driveway is 12 feet.

Find the perimeter and area of length 3cm and width 5 cm
Anni [7]
L = 5 and w = 3

Perimeter = 2(l + w)
P = 2(5 + 3)
P = 2(8)
P = 16 cm


Area = l*w
Area = 5*3
Area = 15 cm^2
