Answer:
The payment for driving 80 miles is $78
Step-by-step explanation:
Mathematical model
Mathematical models are used in disciplines like natural sciences and engineering, among many others.
The data provided in the question allows building a model for the charges of the car rental, knowing there are two fees:
A fixed charge of $50
A variable charge or $0.35 per mile driven.
Part A
Using m as the number of miles driven for the day, the model for the payment for the car rental is:
P(m)=50+0.35m
Part B
Find the payment if the car is driven m=80 miles:
P(80)=50+0.35*80
P(80)=50+28=78
The payment for driving 80 miles is $78

Answer:
Add -3+8
Step-by-step explanation:
You would do this first because it is in the brackets. Usually you would do (*) first but those are just there because the 4 is negative and if they were not there it would get confusing and look like this::[-3+8]--4. So the next step would be the [*].
HOPE THIS HELPS!!!
Answer:
Use PEMDAS
Step-by-step explanation:
Parenthesis, If there are none move on to exponents if there are no exponents move to multiplication. No multiplication? use division. If you dont see division use addition and lastly if there is no addition use subtraction. In the equation, it looks like you have to make the -3 and 8 positive. So, since the -4 is in the parenthesis(P) multiply(M) 4 by 3 and 8 once the three is positive. So your final answer would be either C or D
Its the best i could do but good luck. I tried...
A team of players are planning to prepare a t-shirt for their next season of games. The team has 13 members and each member will have 2 t-shirts. (a)If a t-shirt costs Rs. 375, what will be the total cost of the t-shirts for the team?(b)A sponsor agrees to pay Rs. 7020 out of the total cost of the t-shirts. The balance amount will be paid by each player. How much will be paid by each player?
Answer:
Rs. 210Step-by-step explanation:

Which statements are true of functions? Check all that apply
Cof
All functions have a dependent vanable
All functions have an independent variable
The range of a function includes its domain
A vertical line is an example of a functional relationship
A horizontal line is an example of a functional relationship
Each output value of a function can correspond to only one input value
Answer:
The true statemens are:
All function have (at least) a dependent variable. That is why you can write y = f(x), x is the independent variable, while y depends on x values, so y is the independent variable.
All function have and independent variable (explained above).
A horizontal line is an example of a funcitional relationship (because given a value of x, you can always tell the value of y)
The other statements are false:
The range of a function includes its domain is false.
Domain are the values that x can take and the range are the values that the function (y) can take. One is not included in the other.
A vertical line is an example of a functional relationship is false, because you can not tell the value of y for any value of x.
Each output value of a function can correspond to only one input value is false. An output can be generated by more than one value of x. The horizontal line is an example of that: the same value of y (output) corresponde to any value of x.
Step-by-step explanation:
Answer:
A: All functions have a dependent variable.
B: All functions have an independent variable.
E: A horizontal line is an example of a functional relationship.

Help me with (-6,-7);y=-4x+1
Answer: y=-4x-31
Step-by-step explanation:
To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.
-7=-4(-6)+b [multiply]
-7=24+b [subtract both sides by 24]
b=-31
Now, we know that y=-4x-31 is the equation.

A whole number k is greater than 3. Which of the following is true about k/3?
Answer:
D) It is greater than 1.
Step-by-step explanation:
Since k is greater than 3, it could not be between 0 and 1/3 and also could not be between 1/3 and 1
We also know that it is not equal to 1 because it is greater than 3.
Therefore, it is greater than 1.

Hi does anyone wanna do a math homework assignment? it involves volume and algebra (I'm in alg2/trig)
[tex]\huge\bold\green{Answer:-}[/tex]
Area. The amount of space covered by a two-dimensional object; the amount of carpet you'd need to cover a floor would depend on the floor's area.
Perimeter. The distance around a two-dimensional object; the amount of fence you'd need to surround your yard equals the perimeter of your yard. (The perimeter of a circular object is called the circumference.
Volume. The amount of three-dimensional space inside an object; the amount of liquid inside a soda can represents the can's volume.
Surface area. Measures the amount of "skin" needed to cover a three-dimensional object, neglecting its thickness; the amount of siding you'd need to completely cover a house represents the surface area of that house's walls.
Description Formula Variables
Area of a rectangle A = l · w l = length, w = width
Perimeter of a rectangle P = 2(l + w) l = length, w = width
Area of a circle A = r2 r = radius of circle
Circumference of a circle C = 2r r = radius of circle
Volume of a rectangular solid V = l · w · h l = length, w = width, h = height
Volume of a cylinder V = r2h r = radius; h = height
Surface area of a cube SA = 6l2 l = length of side

Alyssa’s lemonade recipe calls for 9 lemons for every 2.5 gallons of water. Brian’s recipe calls for 12 lemons for every 4 gallons of water. Whose lemonade will require more water if they each use 36 lemons? . can you help me
Answer:
Alyssa’s lemonade recipe
Step-by-step explanation:
→ Work out how much lemons is needed per gallon for Alyssa’s lemonade recipe
9 lemons = 2.5 gallons
(÷ 2.5) = (÷ 2.5)
3.6 lemons = 1 gallon
→ Work out how much lemons is needed per gallon for Brian’s lemonade recipe
12 lemons = 4 gallons of water
(÷ 4) = (÷ 4)
3 lemons = 1 gallon of water
→ Now compare
Alyssa’s lemonade recipe ⇒ 3.6 lemons = 1 gallon
Brian’s lemonade recipe ⇒ 3 lemons = 1 gallon of water
Brian's lemonade recipe requires more water.
Alyssa uses 10 gallons of water for 36 lemons. Brian uses 12 gallons of water for 36 lemons. Therefore Brian's lemonade recipe requires more water.
The owners of a golf course hired a company to determine how many squirrels were living on their property. First, the company put marks on 22 squirrels. Later, the company returned and counted a total of 220 squirrels, of which 11 were marked. To the nearest whole number, what is the best estimate for the squirrel population?
Answer:
Squirrel population is 440 squirrels.
Step-by-step explanation:
It is given that there are 22 squirrels are marked.
Later the company returned and counted a total of 220 squirrels of which are marked were 11.
So, we can set up proportional equation to find the squirrel population.
Let squirrel population is x.
We can set up proportional equation as
[tex]\frac{11}{220}=\frac{22}{x}[/tex]
Cross multiply
11 x=4840
Divide both sides by 11
x=440
Best estimate is 440.

Tonya wrote the equation below which solves for x.
x = 150 minus 6 y
Which equation is equivalent to Tonya’s equation?
x + 150 = 6 y
x + 6y = 150
2x + 3y = 75
2 x minus 3 y = 75
Given parameters:
x = 150 minus 6 y
Interpreting this gives;
minus = subtraction = -
x = 150 - 6y
Now bring the variables together;
x + 6y = 150
The option that matches with this equivalent.
The other choices are wrong;
a, x + 150 = 6 y
x - 6y = 150 wrong
c. 2x + 3y = 75 mulitply through by 2;
2(2x + 3y) = 2(75)
4x + 6y = 150 wrong
d. 2x - 3y = 75
Multiply by 2;
2(2x -3y) = 2(75)
4x - 6y = 150
Answer:
x+6y = 150 (B)
Step-by-step explanation:
