Answer:
The maximum number of days is 5
Step-by-step explanation:
Let
x ----> the number of days
y ---> the total cost to rent a car in dollars
we know that
The fixed rental fee plus the daily fee multiplied by the number of days must be less than or equal to Pasion's budget
so
The inequality that represent this situation is
[tex]25+10x\leq 75[/tex]
Solve the inequality for x
Subtract 25 both sides
[tex]10x\leq 75-25[/tex]
[tex]10x\leq 50[/tex]
Divide by 10 both sides
[tex]x\leq 5\ days[/tex]
therefore
The maximum number of days is 5

B. This is an exponential function because there is a common ratio of 2.
C. This is a linear function because there is a common difference of 3.
D. This is an exponential function because there is a common ratio of 3.
Answer:
A. This is a linear function because there is a common difference of 2
Step-by-step explanation:
Differences are ...
5 - 3 = 27 - 5 = 2The differences of 2 are common, so this is an arithmetic function.
Option: A is the correct answer.
A. This is a linear function because there is a common difference of 2.
Step-by-step explanation:Linear function--
A function is said to be linear if the rate of change is constant.
i.e. the function is increasing by a fixed constant.
Here the table is given by:
Hour (x) Number of Customers f(x)
1 3
2 5
3 7
From the table of values we observe that as the value of increasing by 1 the value of y is increasing by 2.
i.e. the rate of change is constant i.e. 2.
Also, the common difference is 2.
since,
5-3=2
and 7-5=2
Hence, the table represents a linear function.
Find the area of a regular hexagon with an apothem 11.4 yards long and a side 13 yards long. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
area=6×11.4×13÷2=444.6 yd²
Final answer:
The area of a regular hexagon with an apothem of 11.4 yards and a side of 13 yards is approximately 444.6 square yards when rounded to the nearest tenth.
Explanation:
To find the area of a regular hexagon with a given apothem and side length, you can use the formula for the area of a regular polygon:
Area = (1/2) × Perimeter × Apothem
In this case, the perimeter of the hexagon can be calculated by multiplying the length of one side by 6 (since a hexagon has 6 sides). Therefore, the Perimeter = 13 yards × 6 = 78 yards.
Now, plug the values into the area formula:
Area = (1/2) × 78 yards × 11.4 yards
Area = (1/2) × 889.2 square yards
Area = 444.6 square yards
So, the area of the regular hexagon is approximately 444.6 square yards, when rounded to the nearest tenth.

A woman has 14 different shirts: 10 white shirts and 4 red shirts. If she randomly chooses 2 shirts to take with her on vacation, then what is the probability that she will choose two white shirts? Show your answer in fraction and percent, round to the nearest whole percent.
Answer:
1/5; 20%
Step-by-step explanation:
If she is only choosing 2 shirts, and they both have to be white, the probability of choosing those 2 white shirts out of 10 white shirts is 2/10 or, equivalently, 1/5. In percent form, this is 20%
The probability of a woman randomly choosing two white shirts from a collection of 14 shirts (10 white and 4 red) is approximately 49%, derived through the process of combinations calculation in the field of probability.
Explanation:The question relates to the field of probability in mathematics. To calculate her probability of selecting two white shirts, we first need to understand the number of total possible outcomes when she is selecting 2 out of the 14 shirts. This is represented by the combination formula C(n, r) = n! / r!(n-r)!, where n is the total number of items to choose from and r is the number of items to choose. Using this combination formula, we find that there are C(14, 2) = 91 total possible combinations of shirts she could end up with.
Next, we need to find the number of combinations that involve her picking 2 white shirts. As there are 10 white shirts, this is represented by C(10, 2) = 45. So, the probability of her taking two white shirts is then the number of desired outcomes divided by the total number of outcomes, or 45 / 91 which simplifies to approximately 0.4945 or 49% when rounded to the nearest whole percent.

The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation. What is the equation?
Answer:
The equation is 5x + 10y = 800
Step-by-step explanation:
* Lets explain what is the equation and how can we make one
- The equation is a mathematical statement that two things are equal.
- It consists of two expressions, one on each side of an equal sign (=).
* Lets solve the problem
- There are two types of vehicles, large one and small one
- The cost of washing the small vehicle is $5
- The cost of washing the larger vehicle is $10
- They collected from washing both is $800
- To make an equation for the amount collected let the number of the
small vehicles is x and the number of the large vehicles is y
∵ x is the number of the small vehicles were washed
∵ y is the number of the large vehicles were washed
∵ The cost of washing the small vehicle is $5
∵ The cost of washing the larger vehicle is $10
∴ The money collected from the small vehicles = 5 × x = 5x
∴ The money collected from the large vehicles = 10 × y = 10y
- find the total money collected from both
∴ The amount of money collected from both = 5x + 10y
∵ The amount of money collected is $800
- Equate the two expressions above
∴ 5x + 10y = 800
* The equation is 5x + 10y = 800

3 h 2 min
2 h 42 min
3 h 12 min
2 h 52 min
Answer:
The answer is (D): 2 h 52 min
Step-by-step explanation:
write these equations separately as functions:
A(x)=15+0.02m
B(x)=4.69+0.08m
Since we want to find when they are equal, set them equal to each other:
15+0.02m=4.69+0.08m
simplifying this equation gives
10.31+0.02m=0.08m
subtract 0.02m from both sides
10.31=0.06m
divide both sides by 0.06
m=171.833 etc approximately equals 172 minutes
172 min/60=
2 hours and 52 min
Hope this helps!
Answer:
2 h 52 min
Step-by-step explanation:
Let m represent the number of minutes that will make the plans have equal cost. Equating the two plan costs, we have ...
15.00 + 0.02m = 4.69 + 0.08m
10.31 = 0.06 m . . . . . subtract 4.69+0.02m
10.31/0.06 = m = 171.8333... ≈ 172 . . . . minutes at equal cost
There are 60 minutes in an hour, so ...
172 minutes = 120 minutes + 52 minutes = 2 hours + 52 minutes
Plan A will cost the same as Plan B for 2 h 52 min of usage.

x=7
Step-by-step explanation:
Equate the angles 7x-7 and 4x+14 and solve:
7x-7 = 4x+14
7x-4x = 14+7
3x = 21
x = 7
Answer:
x = 7
Step-by-step explanation:
Alternate interior angles are equal. Alternate interior angles look like these two angles.
7x - 7 = 4x + 14 Add 7 to both sides
7x - 7 + 7 = 4x + 14+7 Combine
7x = 4x + 21 Subract 4x from both sides
7x-4x = 4x - 4x + 21 Combine
3x = 21 Divide by 3
3x/3 = 21/3 Do the division

Genet multiplied a 3-digit number by 1002 and got AB007C, where A, B, and C stand for digits. What was Genet's original 3-digit number?
Answer:
539
Step-by-step explanation:
The 007C requires the least significant two digits be in the range 35-39. In order for the 10-thousands digit to be zero, the sum of 1000 times the least digit of Genet's number and 2 times the hundreds digit must result in a sum with no thousands. About the only way to do that is to make the least digit 9 and the hundreds digit 5.
Then you have ...
539 × 1002 = 540078 . . . . . ABC =548
