Answer:

Step-by-step explanation:

The percent markup is basically how much it is MORE than the original.

First, we need to find how much the selling price is more than cost.

Cost = 22.99

Selling Price = 36.99

Markup = 36.99 - 22.99 = $14

How much is the markup, we just found, with respect to cost? That is the markup divided by cost, multiplied by 100 [to convert to percentage]. Shown below:

$\frac{14}{22.99}*100=60.9$

So, the percent markup = 60.9%

Answer choice C is right.

Answer:

The value of x is 108°

Step-by-step explanation:

Given interior angles of parallelogram are:

$\frac{2}{3}x, x, \frac{2}{3}x\ and x$

<u>The sum of interior angles of a parallelogram is 360°.</u>

We will use this information to find the value of x.

So adding up all the angles and putting the sum equal to 360 we get,

$x+\frac{2}{3}x+x+\frac{2}{3}x = 360$

$2x+\frac{2}{3}x+\frac{2}{3}x = 360\\2x + \frac{4}{3}x = 360$

Taking LCM on left side of the equation, as it involves fraction

$\frac{6x+4x}{3} = 360\\\frac{10x}{3} = 360$

Multiplying both sides by 3

$\frac{10x}{3} * 3 = 360 * 3\\10x = 1080$

Dividing both sides by 10

$\frac{10x}{10} = \frac{1080}{10}\\x = 108$

Hence,

The value of x is 108°

Answer:

21 $w^{10}$

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

3 $w^{5}$ × 7 $w^{5}$

= 3 × 7 × $w^{(5+5)}$

= 21 $w^{10}$
