The area of a
parking lot is 600 square meters. A car requires 6 square
meters. A bus requires 30 square meters. The attendant can handle only
60 vehicles. If a car is charged $2.50 and a bus $7.50, how many of each
should be accepted to maximize income?
The number of cars should be 100 and that of bus be 0.
x is the number of cars and y is the number of buses.
Area: 6x + 30y <= 600 simplifies to x + 5y <= 100
Total money collected: 2.50x + 7.50 y …..this is what you want to maximize
OR you want to maximize 2.50 (x+ 3 y)
OR you want to maximize (x+3y)
Replacing the value of x from the Area equation in the above price, we get
100 - 5y + 3y is the maximum amount you can collect
So you want to maximize 100 - 2y. This happens when y is 0.
When y is 0; x will be 100 and you will collect 250.

If a circle has a diameter of 30 meters, which expression gives its area in
square meters?
A. 152. T
B. 30². T
OC. 30. T
OD. 15. T
The area of Circle is 15∧2*π
Hence option A is correct.
According to the question the diameter of circle is 30 meters
we know,
diameter = radius*2
by using this we can say that the radius of the circle is 30/2
that is R = 15 meters
now According to the formula
Area of Circle = R*R*π
Putting the value of R into the formula by Substitution method
Area of circle = 15*15*π
hence by this we can say that,
Area of circle = 15∧2*π

a cyclist competing in a race rides past a water station. The graph of the function d(t) - 1/3 |t-60| represents her distance in kilometers from the water station in t minutes. What does the graoh of the function tell you about her race.
From the given absolute value function, we have that:
The cyclist starts 20 kilometers from the station.The cyclist reaches the station in 60 minutes.What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin.
For this problem, the function is:
d(t) = 1/3|t - 60|.
The d-intercept is given by:
d(0) = 1/3|-60| = 20.
Hence: The cyclist starts 20 kilometers from the station.
The t-intercept is found as follows:
1/3|t - 60| = 0
t - 60 = 0
t = 60.
Hence: The cyclist reaches the station in 60 minutes.

Find the circomference of the circle
Answer:
18.84
Step-by-step explanation:
You are borrowing $10840 to buy a car. If you pay the loan off in 6 years (72 months), estimate your monthly payment by ignoring interest and rounding the loan to the nearest hundred dollars.
If we are borrowing $10840 to buy a car and repaying it in 6 years (or 72 months) , our monthly payment will be $150.55 or rounded of $200.
As per the question statement, we are borrowing $10840 to buy a car and repaying it in 6 years (or 72 months) , what will be the estimate monthly payment by rounding off to the nearest hundred dollars
First we are supposed to find the monthly payment then we can round it off to the nearest hundred dollars.
Total loan borrowed = $10840
Time taken to pay it off = 6 years or 72 months,
Payment to be made per month = [tex]\frac{10840}{72} \\ 150.5556[/tex]
Therefore [tex]150.5556[/tex] dollars is to be paid every month for 72 months.
After rounding off to the nearest hundred dollars we will get $200.
Hence we are supposed to pay approximately $200 every month for 72 months.

Jamaal puts $4100 in a savings bank account. The interest rate on the account is 1.8% compounded quarterly.
How much interest does Jamaal earn after a year?
The compound interest earned by Jamaal after a year is $4174.30.
What is defined as the compound interest?Compound interest essentially means that the interest on a bank account, lending, or investment grows exponentially over time rather than linearly.Compound interest advantages investors, but the term "investor" can mean a variety of things. Banks, for example, profit from compound interest once they lend money as well as reinvest the interest received in making more loans.The formula for finding the compound interest is;
CI = p( 1 + r/n)∧nt
where p is the principal amount = $4100.
r is the rate of interest = 1.8% = 0.018.
t is the total time in years = 1 year.
n is the number of time interest given = 4 times.
Put the values;
CI = 4100( 1 + 0.018/4)∧4(1)
CI = 4100×1.018
CI = 4174.30
Thus, the amount of compound interest earned by Jamaal earned after an year is $4174.30.

(A) Write the equation for the average cost function C.
The equation for the average cost function C [tex]= \frac{0.00048(x - 200)^{3} + 246840 }{x}[/tex]
When a company creates products or services, it is required to pay production-related expenses. Some of these expenses are cyclical and alter as the output does. Expenditures that alter when production changes include things like raw materials, labor, and utility costs. These are referred to as variables. Other expenses are set, such as rent and insurance payments. These fixed expenses do not alter with changes in output.
The sum of the fixed and variable costs is the total cost.
Total Cost = Variable Cost + Fixed Cost
Now as per the question the cost equation is :
[tex]= \frac{C(x)}{x} = \frac{0.00048(x - 200)^{3} + 246840}{x}[/tex]

the difference between two numbers is -1. their sum is -27. find the numbers. let x represent the first number and y represent the second number. solve using system s of equations.
Answer: x = -14, y = -13
Step-by-step explanation:
As stated by the question, we can use a system of equations to help us solve.
First, the difference between two numbers (x and y) is -1. The difference represents subtraction.
x - y = -1
Next, the sum of the numbers (x and y) is -27. The sum represents addition.
x + y = -27
Now, we can solve this system. We will graph both of the equations. The point of intersection is the solution, see attached. This gives us an answer of x = -14 and y = -13.
x - y = -1
x + y = -27

Scaling a Rectangle
A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7.
Scale factor back to original size = 1/7
The transform object is a mathematical mapping from one coordinate system to another. The coordinate system can differ in position (i.e. origin), scale, axis orientation, and relative axis orientation. We are told that the rectangle has been scaled by a factor of 7. This means that if the length and width are x and y respectively, the new scaled measurements will be;7x and 7 years.
Now, to get us back to the original size, all we have to do is divide the new scale measure by a factor of 7.This means the original size will be;
Length = 7x × 1/7
Width = 7y × 1/7
Hence, the scale factor will be 1/7 back to the original size.

In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed). It is not the same as a fee that the borrower might pay to the lender or another entity. Interest advance, but rather on a pro-rata basis as a share of the reward received by risk-taking business people when revenue is earned that exceeds all costs.
For Interest, a customer who borrows money from a bank typically pays interest on it, so they pay the bank more than they borrowed; likewise, a customer who earns interest on their savings may withdraw more than they originally put. When it comes to savings, the bank serves as the borrower while the consumer serves as the lender.

AB = 7 cm, BC = 3 cm, CD = 1 cm, DE = 2 cm, EF = 3 cm, and FG = 1 cm.
Do not include "cm" with your response.
Answer:

Step-by-step explanation:
First, split the figure into 3 rectangles and label the sides so that it is easier to work with.
Then you have to find the unknown values: HG and AH.
HG: Since AB=7 and AB is the longest horizontal side; we know that HG+EF+CD=AB=7. Plugging in the known values: HG+3+1=7 => HG+4=7. Therefore, HG=3 because 3+4=7.
AH: BC and FG are the corresponding sides to AH so AH+FG=BC. Plugging in the known values: AH+1=3. Therefore, AH is 2 because 2+1=3.
Now you have to use the perimeter of rectangle formula which is P=2(L+w) for the 3 rectangles.
Rectangle 1: 2(3+2)=10
Rectangle 2: 2(3+1)=8
Rectangle 3: 2(3+1)=8
Add them all up to find the total perimeter: 10+8+8=26.
