Answer:

C

Step-by-step explanation:

So first, you find the area of a rectangle, which would be 15 * 30 = 450. Next, find the area of the semicircle by doing \pi *r^2 / 2 (you have to divide by 2 because it's only have a circle).

The radius is half of 15, so 15 / 2 = 7.5. This would be:

\pi * 7.5^2 / 2

=\pi * 56.25 /2

=28.125\pi

=28.125*3.14=88.3125

The last step is to add 450 + 88.3125 = about 538.3 m^2

stiks02 [169]

Answer:

$340

Step-by-step explanation:

Given:

Jim is paid 17% for every ad he sells.

He sold an ad today for $2000

Now we have to find the commission.

The commission rate is 17%

If he sells $100, then he gets $17 as commission.

To find the commission on sale ad of $2000, we have to multiply 2000 by 17%

17% of 2000

= \frac{17}{100} *2000

We can simplify 2000 by 100, we get

= 17*20

Commission = $340

He gets $340 as commission for the ad sale of $2000.

Deffense [45]

Step-by-step explanation:

The following prices for the same make  and model used guitar for his work are :

$699.20,$700.30,$680.50,$700.30, and  $800.25.

Mean of ungrouped data = sum of observations/total no of observations

\text{Mean}=\dfrac{699.20+700.30+680.50+700.30+800.25}{5}\\\\\text{Mean}=\$716.11

For median, arrange the given data in ascending order.

$680.50, $699.20, $700.30, $700.30, $800.25

Median = middle value

Median = $700.30

The value that comes most often is called mode.

$700.30 comes two times. So, mode is $700.30

Hence, Mean = $716.11, median = $700.30 and mode = $700.30
