Answer:

9 is 15% of 60.

Step-by-step explanation:

$\text{Formula}=\frac{\text{Number x 100}}{\text{Percent}} =\frac{9 \times100}{15} =60$

Following shows the steps on how to derive this formula and find out 15% of what number is 9.

Step 1: If 15% of a number is 9, then what is 100% of that number? Setup the equation.

$\frac{9}{15} = \frac{Y}{100}$ %

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

$15Y=6\times100\\15Y=600$

Y = $\frac{600}{100} =60$

The length of a rectangle is twice its width. Find its area, if its perimeter is 7 1/3 cm The area of the rectangle is _sq. cm.

Harman [31]

Answer:

The area of rectangle is $2\frac{80}{81}\ cm^2$

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

$P=2(L+W)$

we have

$P=7\frac{1}{3}\ cm=7+\frac{1}{3}=\frac{22}{3}\ cm$

$\frac{22}{3}=2(L+W)$

$\frac{11}{3}=(L+W)$ ----> equation A

Remember that

The length of a rectangle is twice its width.

$L=2W$ ----> equation B

substitute equation B in equation A

$\frac{11}{3}=(2W+W)$

solve for W

$W=\frac{11}{9}\ cm$

Find the value of L

$L=2(\frac{11}{9})$

$L=\frac{22}{9}\ cm$

Find the area of rectangle

$A=LW$

substitute the values

$A=(\frac{22}{9})(\frac{11}{9})$

$A=\frac{242}{81}\ cm^2$

Convert to mixed number

$\frac{242}{81}\ cm^2=\frac{162}{81}+\frac{80}{81}=2\frac{80}{81}\ cm^2$

To find the cost of the truck, you will need to add all the expenses that incurred in addition to the actual cost of the truck.

35000 + 2000 + 1200 + 120 + 220 = 38540

The cost including expenses should be recorded as $38540.
