Step-by-step explanation:

movies is 2.59 and videos is 5.944

//Hope this helps

The correct answer is $6.50 for each video game and $2.50 for each movie. My work:

3 x 2.50 = $7.50 and 5 x 6.50 = $32.50

32.50 + 7.50 = $40.00

12 x 2.50 = $30.00 and 2 x 6.50 = $13.00

30.00 + 13.00 = $43.00

twenty seven percent.

The percent change in the price of gasoline from September to October is calculated using the formula for percent change. Subtracting the September price from the October price and dividing by the September price yields a 15% increase.

To calculate the percent change in the price of gasoline from September to October, we use the formula for percent change, which is
(New Price - Old Price) / Old Price
x 100%. In this case, the price in September was $1.80, and the price in October was $2.07.

The percent change can be calculated as follows:

Therefore, the percent change in the price of gasoline from September to October is 15%.

Answer:

y= 3|x|+5

Step-by-step explanation:

Remember the graph for |x| is shown on the attached picture

Since the picture you show tell us that y=5 when x=0

we have something like the following y=a|x|+5, where 'a' is a constant that represents the slope of the line (whether is the line from one side of the 'y' axis or from the other), we can see that, when x=1, y=8, so we have another point

we can use the equation for slopes using points 1 (0,5) and 2 (1,8)

thus we have that [tex]a=\frac{8-5}{1-0}=3[/tex]

So the answer is y= 3|x|+5

Answer:

The point (3, 3) is not a solution of the first equation, therefore is not a solution of the given system of equations.

Step-by-step explanation:

[tex]y=3x+6\ and\ y=-2x+9[/tex]

To determine if the given point (3,3) is a solution of the given system of linear equations y=3x+6 and y=-2x+9, we substitute the values of x and y into both equations and check if the equations hold true. If both equations are true, then the given point is a solution of the system of equations.

To determine if the given point (3,3) is a solution of the given system of linear equations y=3x+6 and y=-2x+9, we substitute the values of x and y into both equations and check if the equations hold true.

Let's perform the calculations:

Since only one of the equations is true, the given point (3,3) is not a solution of the system of equations.

Answer:

  4 oz of water must be evaporated

Step-by-step explanation:

If we let x represent the amount of water to be evaporated, the relation between the solutions is ...

  0.08 · 36 oz = 0.09 · (36 -x) oz

  0.09x = 36(0.09 -0.08) . . . . . divide by oz; add .09x, subtract .08·36

  x = 36· 0.01/0.09 = 36/9 = 4

4 ounces of water must be evaporated.

Answer:

Step-by-step explanation:

You can divide all the x from the y like , 45/9 =4 so it equals four

Yes, the table does show a proportional relationship and the constant of proportionality is 4.

If the corresponding elements of two sequences of numbers have a constant ratio,

Known as the coefficient of proportionality or proportionality constant, then the two sequences of numbers are proportional or directly proportional.

We know constant of proportionality is when we have the same multiplicative or division factor between two variables.

Given, when x = 3, y = 12, So y = 4x.

Again when x = 6 , y = 24, so, y = 4x and from observation we can conclude that y is 4 times of x or y = 4x.

∴ The constant of proportionality is 4.

Answer:

He must sell $14000 of merchandise

Step-by-step explanation:

The salesperson earns a base salary of $800

This means that he must make

$3600 - $800 = $2800 worth of commisions

Let x, be the value of the mechandise that he needs to sell.

This means that

x*0.20 = $2800

x  = $2800/0.20

x = $14000

He must sell $14000 of merchandise

Answer:

D. (2,1)

Step-by-step explanation:

Fill in the value for y from the first eq (6x-11) into the second:

-2x - 3(6x-11) = -7

Now simplify:

-2x -18x + 33 = -7

-20x = -7-33

20x = 40

x = 2

Now that we have x, plug it into the top eq to get y:

y = 6*2 - 11 = 1

Et voila, x=2 and y=1, so the solution is (2,1).

Answer:

X= 2 and Y=1

There is an unique value of y for each value of x.

Therefore, the equation is a function and a function is also  a relation.

Final answer:

The constant of proportionality for the relationship between the length of the arc intercepted by an 80 degree angle and the radius of the circle is π/9 or approximately 0.349 radians per unit of length.

Explanation:

The constant of proportionality for the relationship between the length of the arc intercepted by an 80 degree angle and the radius of the circle is π/9 or approximately 0.349 radians per unit of length.

This can be determined by using the formula for arc length: L = 2πr(A/360), where L is the length of the arc, r is the radius of the circle, and A is the angle in degrees. Since we know that A = 80 degrees, we can substitute the values into the formula to find the constant of proportionality.

L = 2πr(80/360) = (π/9)r

The mortgage loan amount is $82,500. The closing costs are 3 percent of the loan amount. Therefore, the total closing costs are $2,475.

Sarah Wood and her husband are purchasing a house for $87,500.00, but they are making a down payment of $5,000.00. Therefore, the mortgage loan amount is $87,500 - $5,000 = $82,500. The closing cost for this mortgage loan is 3 percent of the loan amount. Thus, to calculate the total closing costs, we multiply the loan amount by 3%. Therefore, total closing costs are $82,500 * 0.03 = $2,475.00.

So, total closing costs are $2,475.00.

The total closing costs are $2,475.00.

To calculate the total closing costs, we need to find 3 percent of the mortgage loan amount.

First, calculate the mortgage loan amount by subtracting the down payment from the house price: $87,500.00 - $5,000.00 = $82,500.00.

Then, find 3 percent of $82,500.00 by multiplying it by -

0.03: $82,500.00 * 0.03

= $2,475.00.

So, the total closing costs are $2,475.00.

Step-by-step explanation:

Segments which are parallel have the same slope. Find the slope of of YZ. Then using that value, find the slope WX and solve for the value of x.

Slope of YZ is:

[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{6-2}{5-2} =\frac{4}{3}[/tex]

Since they are parallel, then WX has a slope of 4/3 too.

Slope of WX is:

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\\frac{4}{3} = \frac{-4--2}{5-x}\\\\\frac{4}{3} =\frac{-2}{5-x}\\\\ (5-x)\frac{4}{3} = -2\\\\ 20 - 4x = -6\\\\-4x = -26 \\\\ x = 6 \frac{1}{2}[/tex]

Answer:

x = 76°

Step-by-step explanation:

We can solve this by using the angles of intersecting chords theorem. This tells us that when two chords intersect inside a circle, the angle formed is half of the sum of the intercepted arcs of the angle.

This implies that the angle 94° should be half of the sum of Arc measuring x° and the arc measuring 112°. So we can write the equation as:

[tex]94=\frac{1}{2}(x+112)\\[/tex]

We can simplify and solve for x:

[tex]94=\frac{1}{2}(x+112)\\\\94=\frac{1}{2}x+56\\94-56=\frac{1}{2}x\\38=\frac{1}{2}x\\x=38*2=76[/tex]

Hence, x = 76°
