Jim is a radio ad salesperson. He is paid 17 percent for every ad he sells. He sold an ad today for $2,000.00. What is his commi
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.

Help? im confused plss!<br> Find the area of the regular polygon with the given radius or apothem
Snezhnost [94]

Answer:

  50 cm²

Step-by-step explanation:

Given that the regular polygon is a square, there are multiple ways you can jump directly to the answer. Perhaps the simplest is to use the formula for the area of a rhombus:

  A = 1/2(d1)(d2)

where d1 and d2 are the lengths of the diagonals. Here, we see that half the diagonal is 5 cm, so the area is ...

  A = (1/2)(10 cm)(10 cm) = 50 cm² . . . . area of the polygon

__

<em>Alternate solution</em>

If you want to use the radius and the number of sides in a formula, you can consider the area of each triangle formed by radii and a side. That triangle has area ...

  A = 1/2r²sin(α)

where r is the radius and α is the central angle. For an n-sided polygon, the area is the sum of n of these triangles, and the central angle is 360°/n. Then the polygon area is ...

  A = n/2·r²·sin(360°/n)

For n = 4 and r = 5 cm, the area is ...

  A = (4/2)(5 cm)²(sin(360°/4)) = 2(5 cm)²(1) = 50 cm² . . . . area of square

_____

<em>Additional comment</em>

The formula is somewhat different if you start with the length of the apothem. One way to find the area is using the above formula and the relation between the radius and apothem:

  r = a·sec(180°/n)

Another formula uses the apothem directly:

  A = n·a²·tan(180°/n)
