You want to rent a car for a dayl It will cost the daily fee of $50 plus $0.35
per mile driven. Part A: Write an expression that shows the amount you will
pay for the car. Let m=the number of miles you drive for the day. Part B:
How much will you pay if you drive 80 miles?
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:
[tex] y = -\dfrac{4}{5}x + 11 [/tex]
Step-by-step explanation:
(5, 7), (10, 3)
[tex] m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{3 - 7}{10 - 5} = -\dfrac{4}{5} [/tex]
[tex] y = mx + b [/tex]
[tex] y = -\dfrac{4}{5}x + b [/tex]

Answer:
f=x-9
Step-by-step explanation:
Answer:
f(x) = 10
Step-by-step explanation:
f(x)=9-x f(-1)
Put in the -1 for x
f(x) = 9 - (-1)
f(x) = 9 + 1
f(x) = 10

A KIDZ society started a campaign "Plant the Plants " . They bought 750 saplings and wanted to arrange the maximum possible number of 750 saplings in a ground such that the number of rows is equal to the number of saplings in each row .Find the number of rows if 21 saplings were left out after the rearrangement .
Answer:
Three are 27 rows of saplings
Step-by-step explanation:
Since 21 saplings were left out of 750 saplings, the number of saplings arranged will be 750 -21 = 729 saplings
We were told that the number of saplings arranged per row is equal the number of rows
So let’s say the number of saplings arranged per row is x
Automatically, the number of rows too will be x
So the total number of saplings arranged will be;
x * x = x^2
This is equal to 729
x^2 = 729
x^2 = 27^2
Since power is equal, equate the base
This means that x = 27

UPS charges $7 for the first pound, and $0.20 for each additional pound. FedEx charges $5 for the first pound and $0.30 for each additional pound. How many pounds, p, will it take for UPS and FedEx to cost the same?
Answer:
It takes 31 Pounds for UPS and FedEx to cost the same?
Step-by-step explanation:
The equation for the cost of a UPS shipping:
7 + .20x
to check the answer, you can do : 7 + (.20 x 31)
= $14.00
The cost for the cost of the PedEx shipping is:
5 + .30x
to check the answer, you can do : 5x + (.30 x 31)
= $14.00
x - y = 4 and x + y = 9
Answer:
5-1=4 and 5+4=9
Step-by-step explanation:
[tex]\huge\red{ƛƝƧƜЄƦ}[/tex]
System of Linear Equations entered :
[1] x - y = 4
[2] x + y = 9
Graphic Representation of the Equations :
y + x = 4 y + x = 9
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 9
// Plug this in for variable y in equation [1]
[1] x - (-x +9) = 4
[1] 2x = 13
// Solve equation [1] for the variable x
[1] 2x = 13
[1] x = 13/2
// By now we know this much :
x = 13/2 y = -x+9
// Use the x value to solve for y
y = -(13/2)+9 = 5/2
Solution :
{x,y} = {13/2,5/2}

15. A music store sells a copy of a deluxe electric guitar for $295. This is $30 more
than 1/3 the cost of the actual deluxe guitar it is modeled after. What is the cost
of the deluxe electric guitar? Find your solution below. Type the code in exactly.
(ALL CAPS, NO SPACES). Example: If my answer was -76.1 l would type in KHGLB
Answer:
It costs $795
Step-by-step explanation:
$30 more than one half so you have to subtract 30 from 295 then that's 265 which is 1/3 of the acual price. So then you have to multiply 265 by 3 then you get $795.

what is the 9th term in the sequence -1,4,-9,16, -25,
Answer:
Step-by-step explanation:
Wow! There are 2 things going on here, so let's go step by step.
The first thing to notice is that the numbers are going negative, positive, negative, positive. Odd-numbered terms are negative while even-numbered terms are positive. Since 9 is odd number, we know the answer must be negative.
Secondly, the 1, 4, 9, 16 sequence is called the square numbers. They are 1 x 1, 2 x 2, 3 x 3, 4 x 4, etc. The 9th term will be 9 x 9 ( ignoring the negative).
Adding the first point with the second, we get (-81) { negative eighty-one }

A test has a mean of 80 with a standard deviation of 4. Which of the following scores is within one standard deviation of the mean?
A
75
B
77
С
BO
D
90
E
09
Answer:
B
Step-by-step explanation:
Mathematically, we shall be using the z-score here
Z-score = (x-mean)/SD
From the question, mean = 80 and SD = 4
So we want to get the option in the question that has a z-score of 1 or below
Let’s look at 75
80-75 = 5 ( this is clearly above 1 standard deviation of 4)
For 77;
80 -77 = 3
This is less than the standard deviation of 4, meaning it is within 1 standard deviation of the mean
Option B) is correct.
Step-by-step explanation:
Given :
Mean [tex](\mu)[/tex] = 80
Standard Deviation [tex](\sigma)[/tex] = 4
Calculation :
We have to find the score that would be 1 deviation from the mean. Which means, the interval [tex](\mu-\sigma, \mu+\sigma)[/tex]
[tex]\mu-\sigma = 80-4=76[/tex]
[tex]\mu+\sigma =80+4=84[/tex]
The interval is (76,84)
Therefore, option B) is correct.
