You and your friends go to the state fair. It costs $6 to get into the fair
and $2 each time you go on a ride. Consider the relationship between
number of rides and total cost.

Model the equation to show the linear relationship.

Answers

Answer:

[tex]let \: number \: of \: rides \: be \: \: n \\ let \: cost \: be \: \: c \\ n \: \alpha \: c \\ n = kc \\ k \: is \: a \: costant \: of \: proportionality \\ when \: n = 1. \: \: c = 2 \\ 1 = (k \times 2) \\ k = \frac{1}{2} \\ therefore : \\ n = 0.5c[/tex]

Answer:

[tex]\huge\boxed{\sf x = 6 + 2y}[/tex]

Step-by-step explanation:

Let the total cost be x and number of rides be y

It costs $2 on each ride. So, the rides' cost will be:

=> Number of rides * One rides' cost

=> y * 2

=> 2 y

So, The total cost will be:

Total cost = Entrance cost + Rides' cost

Total cost = $6 + $2(Number of rides)

x = 6 + 2y

Two phone companies one is 11/+.16/ min And another is 20+.11/min How many minutes will make both equal amounts

Answers

Answer:

Company one charges $11 + $0.16 per min.

Then if you talk for x minutes, the cost will be:

C₁(x) = $11 + ($0.16 per min)*x

For company two, the prize is $20 + $0.11 per min, and if yo talk for x minutes, the cost will be:

C₂(x) = $20 + ($0.11 per min)*x

Now we want to find the value of x, the number of minutes, such that the cost is the same with both companies.

C₁(x) = C₂(x)

$11 + ($0.16 per min)*x = $20 + ($0.11 per min)*x

($0.16 per min)*x - ($0.11 per min)*x = $20 - $11

($0.05 per min)*x = $9

x = $9/($0.05 per min) = 180 mins

If you speak for 180 minutes, the cost is the same in both companies.

The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?

Answers

Answer:

As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.

Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.

Subtract the 2 hours from 10am:

= 10 - 2

= 8am

Subtract the 15 minutes from 45:

= 45 - 15

= 30

Put that together:

= 8:30 am

They left their house at 8:30 am using this scenario.

A simple impact crater on the moon has a diameter of 15 kilometers. A complex impact crater has
a radius of 30 kilometers. How much greater is the circumference of the complex impact crater than
the simple impact craters?

Answers

Answer:

141.3 km

Step-by-step explanation:

First crater has the radius (that is, half the diameter) of 7.5 km; the circumference of this crater is C = 2(pi)r, or 2(3.14)(7.5 km) = 47.1 km;

Second crater radius is C = 2(pi)(30 km) = 188.4 km

The circumference of the complex (larger) impact crater is

(188.4 - 47.1) km greater than the circumference of the simple (smaller) crater:

141.3 km

Sally can paint a room in 9 hours while it takes Steve 5 hours to paint the same room. How long would it take them to paint the room if they worked​ together?

Answers

Answer: About 3 hours and 5 minutes to paint the room together.

Step-by-step explanation:

Sally can paint 1/5 of the room in an hour and Steve can paint 1/8 of the room in an hour.

Room/Hour

1/5 ± 1/8 =8/40  

8/40+5/40=13/40

How long to paint the room?

13/40 x 1= 40/13

40÷13=3.0777

So the answer will be Sally and Steve can paint the room in about 3 hours and 5 minutes

__m²
Composite made up of a rectangular prism surmounted by a triangular prism. The rectangular prism has dimensions of 16 meters wide by 20 meters long by 12 meters high. The triangular prism has dimensions of 16 meters wide by 20 meters long with a triangular altitude of 8 meters high.

Answers

SEE THE IMAGE BELOW (I REALLY HOPE THIS IS CORRECT!!!)

Answer:

1764 m²

Step-by-step explanation:

Refer to attached picture.

All given dimensions are given on the picture (not to scale).

Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:

[tex]b/2 = \sqrt{11.3^2-8^2} = \sqrt{64} = 8m, \\b = 16 m[/tex]

It has 9 faces and the total surface area is:

S = 16*20 + 2(20*12) + 2(20*11.3) + 2(16*12) + 2(1/2*8*16)  = 1764 m²

Answer:

Step-by-step explanation:

The answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

What is a function?

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We know when the graph is symmetric about the origin it is an off function.

When the graph is symmetric about the y axis it is an even function.

When f(-x) = f(x) it is an even function

When f(-x) = -f(x) it is an odd function.

Thus, the answers are odd, even, even, and odd respectively the graph is symmetric about the y axis it is an even function.

Noah says, "If I try to write 100 expanded, it should have zero factors that are 10, so it must be equal to 0." Do you agree? Why or why not?

Answers

Answer:

Disagree

Step-by-step explanation:

5x−4y=−10
y=2x−5


x=x=x, equals
y=y=y, equals

Answers

Answer:

✎ ANSWER:-

[tex]y = 2x - 5[/tex]

Substitute the value of y as 2x - 5 in the equation.

[tex]5x - 4y = - 10 \\ 5x - 4(2x - 5) = - 10 \\ 5x - 8x + 20 = - 10 \\ 5x - 8x = - 10 - 20 \\ - 3x = - 30 \\ x = \frac{ - 30}{ - 3} \\ x = 10[/tex]

Now, find the value of y

[tex]y = 2x - 5 \\ y = 2(10) - 5 \\ y = 20 - 5 \\ y = 15[/tex]

⎇ x = x = x, equals 10

⎇ y = y = y, equals 15

Answer:

if y = 2x-5

then in the second equation we can find the value of x

5x-4(2x-5) = -10

5x-8x+20 = -10

-3x = -30

x = 10

then the value of y = 20-5 = 15

therefore the value of x = 10 and y =15 (ans)
