The area of a parallelogram is 240 cm² and the height is 20 cm² find the corresponding base

1 answer:

5 0

If the area of a parallelogram= bh
$240 = b20 \\ \\ divide \: both \: sides \: by \: 20 \\ \frac{240}{20} = \frac{b20}{20} \\ \\ b = \frac{24}{2} \\ b = 12cm$
The answer is d

10. The perimeter of a regular nonagon is 162 inches. The apothem is 97.8 inches. Find the area.

Katen [24]

Answer:

The area of the regular nonagon is 7921.8 square inches.

Step-by-step explanation:

Geometrically speaking, the area of a regular polygon is determined by following area formula:

$A = \frac{p\cdot a}{2}$ (1)

Where:

$A$ - Area of the regular polygon, in square inches.

$p$ - Perimeter, in inches.

$a$ - Apothem, in inches.

If we know that $p = 162\,in$ and $a = 97.8\,in$ , then the area of the regular nonagon is:

$A = 7921.8\,in^{2}$

The area of the regular nonagon is 7921.8 square inches.

A department store buys 200 shirts at a cost of $5,400 and sells them at a selling

jekas [21]

Number of shirts a department store bought = 200

Cost price of 200 shirts = $5400

Cost price of 1 shirt :

$=\tt \frac{5400}{200}$

$\color{plum} =\tt \$27$

Thus, the cost price of one shirt = $27

Price at which the department store sold each shirt = $30

Which means :

▪︎Cost price of shirt = $27

▪︎Selling price of shrit = $30

Since selling price is greater than cost price, there was a markup in the price of the shirts.

We know that :

$\color{hotpink}\tt \: markup \: percentage = \color{plum} \frac{selling \: price - cost \: price}{cost \: price } \times 100$

Markup percentage in the price of the shirts :

$= \tt \frac{30 - 27}{27} \times 100$

$= \tt \frac{3}{27} \times 100$

$= \tt \frac{3 \times 100}{27}$

$= \tt \frac{300}{27}$

$\color{plum} = \tt11.1 \%$

Thus, the percentage of markup = $\tt 11.1 \%$

Therefore, the percentage of markup in the shirt's price = $\color{hotpink} \tt11.1 \%$

Write the linear equation in slope-intercept form.<br><br> -6x + y = 19

Aleonysh [2.5K]

Your answer would be y= 6x + 19

You get rid of the variable on the left side by adding it to both sides giving you y = 6x + 19
Hope it helps

A city has 7204 recycle bins. The city gives half of the recycle bins to it's citizens. The rest of the recycle bins are divided

Tju [1.3M]

The number of recycle bins that the city gives to citizens:
7204 : 2= 3602
The number of recycle bins is left:
7204 - 3602= 3602
The largest number of bins that can be given in each group:
3602 : 23 = 156 (residual: 14)
=> There are 14 bins left over.
