A freight train is traveling at an average rate of 45 miles per hour. Which equation represents the situation?

Let h represent the hours traveled.
Let m represent the miles traveled.
m = 45h
h = 45m
m = 45 + h
h = 45 – m

Answers

Answer 1
Hi there!

The answer would be A. m = 45h

Hope this helps
Answer 2

Answer:

m=45h

Step-by-step explanation:

The independent variable here is h, the number of hours it traveled, and this determines m.

The sum to n terms of a geometric sequence is

[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]

where a is the first term and r the common ratio

Here a = 3 and r = 12 ÷ 3 = 4 , thus

[tex]S_{8}[/tex] = [tex]\frac{3(4^{8}-1) }{4-1}[/tex]

Profits increase until the price of the shoes reaches $22.
Costs decrease until the price of the shoes reaches $22,​

Answers

Answer:

Profits increase until the price of the shoes reaches $22.

There are more prices with positive revenues than positive profits.

Step-by-step explanation:

In the picture attached, the problem is shown.

The first sentence is true because the profit curve has a maximum at $22.

The second sentence is true because the profit is computed as follows:

profit = revenue - cost

and cost decreases as the price increase; therefore, there are positive revenues with negatives profits.

The  two sentences which correctly interpret the graph include:

Profits increase until the price of the shoes reaches $22.There are more prices with positive revenues than positive profits.

What is a Graph?

This is defined as a pictorial representation of numbers or variables in an organized manner.

The profit curve has a maximum at $22 which makes statement 1 correct while from the graph we can also deduce that there are more prices with positive revenues.

You use a garden hose to fill a wading pool if the water rises 12 cm or seven minutes and you record the data point of (21,y) What is the value of Y?

Answers

Answer:

The rate of change at which the water level rise is 13/6 cm/minute.The slope of the line is 13/6.The value of y is 23, (12,23).

Step-by-step explanation:

In the question the water rises 13 cm every 6minutes. Taking x to represent the time in minutes and y to represent the rise in cm then, find the rise y in time x as;

6 minutes=13 cm

1 minute=?---------------------perform cross multiplication

(1*13)/6=13/6

Hence in 1 minute, the rise is 13/6 cm

Thus in 12 minutes, the rise will be ;

12 * 13/6 = 2*13= 26 cm

(x,y) will be (12,26)

Finding the slope of the line using point (6,13) and (x,y)

The rate of change at which the water level rises equals the slope of the line.This is the justification.

Answers

Answer:

just read through this document

The cost of a baseball ticket is $26.64 and the cost of a football ticket is $74.99.

If a family of 5 would like to attend one game during the football season and one during the baseball season,

The cost of a baseball ticket is $133.2 and the cost of a football ticket is $374.95.

What is the system of equations?

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

For the 2009 Major League Baseball and National Football League seasons, based on average ticket prices,

Three baseball tickets and two football tickets would have cost $229.90, while two baseball tickets and one football ticket would have cost $128.27.

Let x represents the cost of one baseball ticket and y represents the cost of a football ticket.

Then,

3x + 2y = 229.90

2x + y = 128.27.

The solution of the system of the equation is the intersection point of the line.

The solution = (26.64, 74.99)

The cost of a baseball ticket is $26.64 and the cost of a football ticket is $74.99.

If a family of 5 would like to attend one game during the football season and one during the baseball season,

the cost of a baseball ticket is $26.64x 5 = $133.2 and the cost of a football ticket is $74.99x5 = $374.95.

Therefore, all the required value is given above.

The cost of renting an apartment can be modeled by the function C(m)=900m+1400, where C(m) is the cost in dollars for m months of living in the apartment. State the meaning of the slope and y-intercept of this function with respect to the costs associated with renting the apartment.

Answers

Answer:

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Step-by-step explanation:

This function is linear, which means that it increases at a steady rate and has the following form:

[tex]y(x) = a*x + b[/tex]

Where "a" is the slope or the rate at which "y" changes for every change in "x". While "b" is the number at which the function crosses the "y" axis.

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

At the Laika Boss Kennel Club, there are 15 dogs that are hairy or small, 2 dogs that are hairy and small, and 9 dogs that are small. How many dogs are hairy?

Answers

Answer:

8 hairy dogs

Step-by-step explanation:

There are 15 dogs that are hairy or small

2 that are hairy and small

9 that are small

small - ( hairy and small) =just small

9 -2 = 7 small only dogs

Take the total dogs minus the small dogs minus the small and hairy dogs to find the hairy dogs

15 - 7 - 2 =6

There are 6 hairy dogs

2 small and hairy dogs

7 small dogs

total 15 dogs

If we want the total of the hairy dogs

2 small and hairy + 6 hairy = 8 hairy dogs

If you have 4 different colors and probability of getting 1 color it would be 1/4

Answer:

2% chances

Step-by-step explanation:

The probability of spinning red is 2 out of 4 because since there is 4 colors and spinning a color twice it can't happen.

How do i know

1: Divide the number of color by the number of  outcomes

2: So since there are 4 colors and twice means 2.

3: 4 divided by 2 = 2% chances.

Answers

Answer:

[tex]\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}[/tex] best completes this argument

Step-by-step explanation:

Circumference of circle =[tex]\pi \cdot d[/tex]

Where d is the diameter of circle

We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to [tex]\frac{360^{\circ}}{n^{\circ}}[/tex]

So, Number of sectors =  [tex]\frac{360^{\circ}}{n^{\circ}}[/tex]

The arc length of each sector is the circumference divided by the number of sectors

[tex]\Rightarrow \frac{\pi \cdot d}{\frac{360^{\circ}}{n^{\circ}}}[/tex]

Diameter d = 2r (r = radius)

[tex]\Rightarrow \frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}[/tex]
