Answer:

∠ Q ≈ 53.1°

Step-by-step explanation:

cos Q = \frac{adjacent}{hypotenuse} = \frac{QS}{QR} = \frac{6}{10} , then

∠ Q = cos^{-1} (\frac{6}{10} ) ≈ 53.1° ( to the nearest tenth )

4. Break-Even Analysis
DiKsa [7]

Answer:

x = 1178 games

Step-by-step explanation:

Let the number of games = x

Let the total cost = Tc

Let the total revenue = Tr

Given the following data;

Investment = $10,000

Cost of each game = $1.50

Selling cost = $9.99

Total cost, Tc = (Cost of each game * Number of games) + Investment

Tc = 1.50x + 10000

Total revenue, Tr = Selling cost * Number of games

Tr = 9.99x

Breakeven point is when total cost is equal to total revenue;

Tc = Tr

1.50x + 10000 = 9.99x

9.99x - 1.50x = 10000

8.49x = 10000

x = \frac {10000}{8.49}

x = 1177.86 ≈ 1178 games.

<em>Therefore, the number of games that must be sold before the business breaks even is 1178 games. </em>

Which of these is a point-slope equation of the line that is perpendicular to y-25=2(x-10) and passes through (-3,7)
OLEGan [10]
Y = 2x +13

We know the slope to be 2 because lines that are parallel have the same slope. Then we can solve using slope-intercept form and  the known point. 

y = mx + b ----> Input known values
7 = (2)(-3) + b ---> Multiple
7 = -6 + b ----> Subtract 3 from both sides
13 = b

Now we can use the y-intercept found and the slope to write the equation above.

How can you best describe a stop sign using polygons? the sign has sides, so it is . it appears to be because the sides and angl
USPshnik [31]

A polygon is a two-dimensional closed object. The polygon that best describes a stop sign is a regular octagon.

<h3>What is a polygon?</h3>

A polygon is a two-dimensional closed object with n number of straight sides that is flat or planar and the value of n is always greater than 2 (n>2).

<h3>What is an octagon?</h3>

An octagon is a polygon that has 8 number of sides.

As we know that a stop sign has 8 sides, therefore, the polygon that is in the shape of the stop sign is an octagon.

An octagon has 8 sides, and as it is mentioned in the problem that sides and angles appear to be congruent, therefore, the polygon must be a regular polygon.

Hence, the polygon that best describes a stop sign is a regular octagon.
