Let x represent the rental cost for each movie.

Let y represent the rental cost for each video game.

We were told that One month Tony rented 5 movies and 3 video games for a total of 532. This means that

5x + 3y = 32

Also, the month, he rented 2 movies and 12 video games for a total of $83. This means that

2x + 12y = 83

Dividing through by 2, we have

x + 6y = 41.5

x = 41.5 - 6y

Substituting x = 41.5 - 6y into 5x + 3y = 532, we have

5(41.5 - 6y) + 3y = 32

207.5 - 30y + 3y = 32

- 30y + 3y = 32 - 207.5

- 27y = - 175.5

y = - 175.5/- 27

y = 6.5

x = 41.5 - 6(6.5) = 41.5 - 39

x = 2.5

Rental cost for each movie = $2.5

Rental cost for each video game = $6.5

Answer:

9 cm

Explanation:

We are given the following information:

Diameter = 24 cm

Angle FOG = 3/4 rad

The formula for calculating arc length is written below:

Therefore, the arc length is 9 cm

The given inequality has the following solution set

9.52 ≤ x ≤ 22.22

If we express this as an interval, we get [9.52, 22.22].

Here is the inequality which is Kali's earning potential

200 ≤ 15.75x + 50 ≤ 400

To solve the inequality, we must isolate the variable in the center; if we remove 50 from each of the three sides, we get:

200 - 50 ≤ 15.75x + 50 - 50 ≤ 400 - 50

150 ≤ 15.75x ≤ 350

Now we must divide both totals by 15.75, yielding:

150/15.75 ≤ 15.75x/15.75 ≤ 350/15.75

9.52 ≤ x ≤ 22.22

This is the inequality's solution; the solution set expressed as an interval will be [9.52, 22] or 9.52 ≤ x ≤ 22.22

Step-by-step explanation:

Our total is 71,482 so let's set our equation to 71482=_________

Now we have $38,295 for one car, and we will subtract it from the total to find the other car, as there are 2 cars.

Equation:

71482-38295=x OR 71482=38295+x

X is the cost of the second car.

The minimum result (to 2 dp) of a / b is 38.66

Given:

a=460 rounded to the nearest 10

b=11.9

Now, substitute the values of a and b in a/b,

a/b = 460/11.9

Multiply the same integer(10) by both the numerator and denominator,

a/b = 4600/119

Answer: (x, y) = (-8/5, -9/5)

Answer:

-9

Step-by-step explanation:

We are working with multiplications and divisions, which have no precedence over each other. So we can do the operations in order. It is important to remind that in these operations, if two numbers have different signals, the result of the operation is negative, otherwise, positive.

-36 ÷ 1/4

Different signals, so the result will be negative

-36 ÷ 1/4 • (-1/8) = -144 * (-1/8)

Same signal, so positive

-36 ÷ 1/4 • (-1/8) • (-3) = 18 * (-3) = -54

-36 ÷ 1/4 • (-1/8) • (-3) ÷ 6​ = -54 ÷ 6​ = -9

The Solution:

Given that a car that cost $10500 was offered as a loan with a down payment of $800.

This means the loan balance will now be:

The loan payment plan is a monthly payment of $187.53 for 60 months.

We are required to find how much was paid in interest.

We shall take the difference between the total payment and the loan balance.

Therefore, the correct answer is $1552

Let's begin by listing out the information given to us:

Mean = $8,000, SD = $1,500

In a sample of 300, how many pay more than $6440?

Notice that we are dealing with simple interest, and therefore given by the formula:

I = P * R * T

where P = $34,011

R = 6% in "decimal" form (0.06)

T = 4 (for 4 years)

Then, we have:

I = 34011 * 0.06 * 4 = $8162.64

This is the interest Brittany earned in 4 years.

Based on the information given, the standard deviation for the observation is: 23.802698 or approximately 24.

The standard deviation in statistics is a measure of the degree of variation or dispersion in a set of values. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.

The formula for Standard deviation is given as:

σ[tex]= \sqrt{\frac{1}{N-1} \sum_{i=1}^N (x_i - \overline{x})^2} .[/tex]

Where

σ = population standard deviation

[tex]\bar x[/tex] =  mean

x = each value of the population

n = number of observation

Note that mean ([tex]\bar x[/tex]) = [tex]\( \frac{1}{n} \sum_{i=i}^{n} x_{i} \),[/tex]

[tex]\bar x[/tex] = (5+10+10+10+10+12+15+20+20+25+30+30+40+40+60+60+65+70+70+70)/20

= 33.6

Hence the standard deviation for travel times for these  20 New York workers is:

Standard Deviation = [tex]\sqrt{\frac{\sum(x_{1} - {\bar x})^{2} }{n-1} }[/tex]

= √ [(5-33.6)²+ (10 - 33.6)² + .... + (70 - 33.6)²]/(20-1)]

Standard Deviation = √(10764.8)/(20-1)

SD = √(10764.8/19)

After 2.14 hours the trains are exactly 300 miles apart.  

Two trains leave the same station at the same time, one traveling west at a constant speed of 60 miles per hour, the other traveling south at a constant speed of 80 miles per hour.

The time both of them will travel 300 miles can be calculated as follows:

Therefore,

speed = distance / time

distance = speed × time

The train that travel west:

let

t = time of the train that travel west

distance = 60t

The train that travel south:

distance = 80t

Therefore,

total distance = 60t + 80t

300 = 140t

t = 300 / 140

t = 2.14285714286

The value of of angle x of the circumscribing circle is x° = 140°

In the above question, the following figure is given, where

The angle inside the circle made by the intersection of two line segments is = 40°

We need to find the angle x made by the angle made by the tangents outside the circle

A line that touches a curve or a circle at one point is said to be tangent.

The point of tangency is the intersection of the tangent line and the curve.

We'll find the value of of angle x using the theorems of the circumscribing   circle.

The sum of opposite angles of a circumscribing quadrilateral is always 180°

Using this property we can write,

40° + x° = 180°

x° = 180° - 40°

x° = 140°

A parabola is a mirror-symmetric planar curve with a rough U-shape. It can be defined by many seemingly unrelated mathematical descriptions that all relate to the same curves.

One way to interpret a parabola is with a line and a point (the focus) (the directrix). The directrix is less significant. The parabola lies between the directrix or the focus and the endpoints in this plane that are uniformly spaced apart.

a) y=-0.5x² + 2 vertex is at (0,2)
