By solving a system of equations, we can see that renting a video game costs $1.50 and a movie costs $5.50

First, let's define the variables:

We know that renting 5 movies and 3 video games costs $32, then:

5*m + 3*v = 32

And renting 2 movies and 12 video games will costs $29.

2*m + 12*v = 29

Then we have a system of equations at:

5*m + 3*v = 32

2*m + 12*v = 29

Using the second equation, we can find the value of m.

2m = 29 - 12v

m = (29 - 12v)/2

m = 14.5 - 6v

Now we can replace that in the other equation:

5*m + 3*v = 32

And replace the equation for m:

5*(14.5 - 6v) + 3v = 32

72.5 - 30*v + 3v = 32

72.5 - 27v = 32

72.5 - 32 = 27v

40.5 = 27v

40.5/27 = v

1.5 = v

So the cost of renting a videogame is $1.5

And for a movie it is:

m = 14.5 - 6*1.5

m = 5.5

The cost of renting a movie is $5.5

Using the scale factor of the similar triangles, the height of the tree is: 75 ft.

The scale factor of similar triangles is the ratio of the lengths of corresponding sides. It represents the relationship between the size of two similar triangles. If the scale factor is "k", then any side length of the larger triangle is "k" times the length of the corresponding side in the smaller triangle.

The diagram given shows that the bigger triangle is a copy of the smaller triangle that is enlarged by 2. This means the scale factor is 2.

Therefore: the height of the tree = 150/2 = 75 ft.

Answer: To calculate the average number of litres per purchase, we need to add the total number of litres purchased and divide by the number of purchases:

Total litres = 56 + 64 + 70 + 54 = 244

Number of purchases = 4

Average number of litres per purchase = 244 / 4 = 61

So the average number of litres per purchase is 61 litres.

To calculate the average cost per litre, we need to add the total cost of the gasoline and divide by the total number of litres purchased:

Total cost = (56 x $0.99) + (64 x $1.065) + (70 x $1.015) + (54 x $1.045)

Total cost = $55.44 + $67.36 + $71.05 + $57.63 = $251.48

Average cost per litre = $251.48 / 244

Average cost per litre = $1.03

To calculate the average cost of gasoline per kilometer, we need to divide the average cost per liter by the average distance per liter in km:

Average cost per kilometre = $1.03 / 8.75

Average cost per kilometre = $0.118

So, the average cost of gasoline per kilometer is $0.118.

The monthly interest payment is calculated by multiplying the average balance by the monthly interest rate.

To find the monthly interest rate, we need to divide the annual interest rate by 12 (since there are 12 months in a year).

24% annual interest rate / 12 months = 2% monthly interest rate

Now that we have the monthly interest rate, we can calculate the monthly interest payment by multiplying the average balance by the monthly interest rate.

$375 average balance x 2% monthly interest rate = $7.50 monthly interest payment

So the monthly interest payment in this situation is $7.50

The total surface area of the cylinder is 44.72 cm2.

Radius is the straight line distance from the center of a circle or sphere to its perimeter or surface. It is the longest chord of a circle or sphere and is equal to half of the diameter. It is an important measurement in mathematics, engineering, and science. Radius is an important concept for calculating the area, circumference, and volume of a two-dimensional or three-dimensional shape.

The total surface area of a cylinder with a base radius of 2cm and height of 6cm is calculated using the formula 2πr(r+h). In this case, 2π(2)(2+6) = 44.72 cm2. Therefore, the total surface area of the cylinder is 44.72 cm2.

To solve this equation, we can use algebra. We start by isolating a on one side of the equation. We can do this by subtracting b from both sides of the equation. This leaves us with a+b-b-13=17-b. Simplifying this equation, we get a-13=17-b. We can then add 13 to both sides to get a=17-b+13. We know from the equation that ab=40, so we can substitute b with 40/a. Plugging this into the equation, we get a=17-(40/a)+13. Simplifying this equation, we get a=34. Therefore, the value of a is 34.

An angle is said to have a measure of 1 radian if it is subtended at its center by an arc of length 1 unit in a unit circle.

Since the triangle exists an isosceles triangle, the base angles are equal.

The three interiors angles of the triangle are,

(3 x+47),(4 x+6),(4 x+6)

3 x+4 x+4 x=180-47-6-6

This simplifies to,

11 x = 121

We divide both sides by 11 to get,

The measure of the angles are,

It is possible to compute the value of cos 135 degrees by first creating an angle of 135° with the x-axis, and then determining the coordinates of the point (-0.7071, 0.7071) on the unit circle.

You need the following formula to determine the precise value of cos(135):

cos(a+b) = cos(a + b) - cos(a + b) - sin(a + b)

In this instance, then, it would be:

Cos (45 + 90) = Cos (135) = Cos (45)

Sin 90 = (2)/2 0 - (2)/2 1 = 0 - (2)/2 = - (2)/2. Cos 90 - Sin 45.

Step-by-step explanation:

You want to know the population of bacteria an hour ago if it was 1 million 20 hours ago and 1/2 million 10 hours ago, and decreasing exponentially.

The population can be described by a function of the form ...

  P = p0·(1/2)^(t/h)

where p0 is the initial population, and h is the half-life.

Here, we have p0 = 1 million, h = 10 hours, and we want to evaluate this function at t=19.

The population is ...

  P = 1·(1/2)^(19/10) ≈ 0.2679 . . . . million

The population an hour ago was about 268 thousand.
