Answer:
Base rate: $120
Rate: $2 per person
Equation: f(x)=2x+120
Step-by-step explanation:
If 30 people cost $180 and 50 people cost $220, the charge for 20 extra people is $40. This means, [tex]\frac{220-180dollars}{50-30people}=\frac{40dollars}{20people}=2\frac{dollars}{person}[/tex].
These values correspond to a base rate for the bus of $120.
The function for the cost per bus with x number of people on it would be:
[tex]f(x)=2x+100[/tex]
This can be checked by using the values given in the problem:
[tex]f(30)=2(30)+120=180\\f(50)=2(50)+120=220[/tex]
The base rate of $120 and $2 per person satisfies the given equation and established values.

Answer:
b=-9
intersection point (3, -3)
Step-by-step explanation:
There are a couple of ways to do this. The method that does not involve calculus is to set the two equations equal and find 'b' such that there is exactly one solution.
x^2 -4x = y = 2x +b
In standard form, this is ...
x^2 -6x -b = 0 . . . . . . . we call this the "combined quadratic"
This will have one solution when the discriminant is zero. You may recall that the discriminant of quadratic ax^2 +bx +c is d = (b^2-4ac). We want ...
d = (-6)^2 -4(1)(-b) = 0
36 +4b = 0 . . . . . simplify
b = -36/4 = -9 . . . solve for b
Then the linear equation is ...
y = 2x -9
__
If the discriminant is zero, the solution to the "combined quadratic" is ...
x = -b/(2a) . . . . . . . . with a, b, c from the quadratic form (not y-intercept)
x = -(-6)/(2(1)) = 3
And the point of intersection of the line and the parabola is ...
y = 2(3) -9 = -3 ⇒ (x, y) = (3, -3)

THE TOPIC IS: AREA OF CIRCLES!! PLEASE HELP ME WITH THIS QUESTION!!! WHATS THE ANSWER?? I WILL GIVE YOU BRAINLIEST AND A THANKS!!! AND PLS PUT AN EXPLANATION!! THANK YOU
Answer:
Step-by-step explanation:
6) diameter = 2 cm
Radius is half of diameter
r = 2 /2 = 1 cm
Area of circle = πr² {Plugin r = 1 in the formula}
= π*1²
= π cm²
7) r = 7.4 cm
Area = πr²
= π * 7.4*7.4
= 54.76π cm²

Sin(2/3+3/5) help please
Answer:
Answer ≈ 0.022
Step-by-step explanation:
For these types of questions with sin cos or tan, you will need to use a calculator. There is no other way as far as I have seen on the internet to solve this type of problem. Anyways, what you have to do is take your calculator and put in:
sin
sin(2/3+3/5) exactly like that
and the calculator will give this to you:

Find the volume of a cone with a base diameter of 8 cm and a height of 6 cm.
The volume of a cone is equal to 13 times the area of the base πr2 π r 2 times the height h . Substitute the values of the radius r=6 and height h=8 into the formula to find the volume of the cone. Pi π is approximately equal to 3.14
Amber coaches soccer and volleyball. She coaches both sports for a total of 10 hours each day. The soccer practice lasts 1 hour more than twice as long as the volleyball practice. Part A: Write a system of equations to model the situation. Use v for the number of hours Amber coaches volleyball in a day and s for the number of hours she coaches soccer. ( Part B: How many hours each day does Amber spend coaching each sport? Show your work. ( Will Mark Brainliest. Only answer if your 100% sure. This is very important).
Step-by-step explanation:
part a: Total is 10 hours
soccer: 2v + 1
volleyball: v
part b: 10 = 2v + 1
-2v = -10 +1
-2v = -9
v = -9 ÷ -2
v = 4.5
volleyball is 4.5 hours
if soccer is one hour longer than volleyball then soccer is 5.5 hours
4.5 + 5.5 is a total of 10 hours :)

(4.5)x+ 3x + 2
Answer:
23x +2
Step-by-step explanation:
20x + 3x + 2 = 23x + 2, also close ur curtains ouch
Based on the information given, the value of the expression is 23x + 2.
From the information given, the expression that was given is (4.5)x+ 3x + 2. This simply means that one has to multiply the values in the bracket first and solve it. This will be:
= (4 × 5)x + 3x + 2
= 20x + 3x + 2
= 23x + 2

About how much cardboard is needed to make the inner tube for a roll of paper if the tube has a radius of 2.25 cm and is 24 cm long?
382 cm
339 cm?
679 cm
371 cm
Step-by-step explanation:
Cardboard needed to make tube =
Circumference of Circle base (remember the base is hollow therefore there is no area needed.) x Length of Tube
given r = 2.25cm
L = 24cm
Cardboard needed =
[tex]2\pi \: rl = \\ 2\pi(2.25)(24) \\ = 2\pi(54) \\ = 108\pi {cm}^{2} \\ = 339 {cm}^{2} [/tex]
The cardboard is needed to make the inner tube for a roll of paper if the tube has a radius of 2.25 cm and is 24 cm long will be 339 cm². Option B is correct.
What is surface area ?The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.
The cardboard is needed to make the inner tube for a roll of paper is found as;
Surface area of cardboard;
A=2πRL
A=2×3.14×(2.25)(24)
A=339 cm².
Hence,the cardboard is needed to make the inner tube for a roll of paper will be, 339 cm².

Answer:
min: $65
per hour: $7.50
Step-by-step explanation:
The equation tells you Monica expects her pay to be $65 when she works 0 hours. That will be the minimum.
y = 7.5·0 +65 = 65 . . . for 0 hours
It also tells you the pay is expected to go up by $7.50 if she works 1 hour. That will be her hourly rate.
y = 7.5·1 +65 = 72.5 . . . for 1 hour; an increase of 7.50 over the minimum.
Minimum pay: $65
plus $7.50 per hour
