Tyrell is traveling to Chicago, Illinois. He takes a cab service from the airport to his hotel. The table shows the linear relationship between the number of miles the cab travels, x, and the total fee, y.
Cab Fare
Number of Miles Total Fee
2 $13.00
5 $17.50
7 $20.50
10 $25.00
15 $32.50
What does the y-intercept mean in this situation?
For every additional mile the cab travels, the total fee increases by $10.00.
For every additional mile the cab travels, the total fee increases by $1.50.
When the cab travels 0 miles, the total fee will be $1.50.
When the cab travels 0 miles, the total fee will be $10.00.
Answer:
When the cab travels 0 miles, the total fee will be $10.00.
Step-by-step explanation:
We Know
2 miles = $13.00
5 miles = $17.50
3 miles = 17.50 - 13.00 = $4.50
1 mile = 4.50 / 3 = $1.50
So, for every 1-mile go, the cost is increasing by $1.50; this is the slope.
What does the y-intercept mean in this situation?
It is the total fee that Tyrell pays when the cab goes 0 miles (when he first steps in the cap).
So, the answer is D. When the cab travels 0 miles, the total fee will be $10.00.

Answer:
B) 16.47
Step-by-step explanation:
In order to find the mean of grouped data with intervals, we use the formula
(∑f * m) / (∑f)
where (∑f * m) is the sum of the product of each frequency (f) and the corresponding midpoint (m) for its interval and (∑f is the sum of each frequencyStep 1: First, we need to find the sum of the frequencies: ∑f = 2 + 3 + 8 + 4 = 17
Step 2: Next, we need to find the midpoint (m) of each interval. We do this by averaging the end points of each interval
m of first interval: (9.5 + 12.5) / 2 = 11
m of second interval: (12,5 + 15.5) / 2 = 14
m of third interval: (15.5 + 18.5) / 2 = 17
m of fourth interval: (18.5 + 21.5) / 2 = 20
Step 3: Now, we multiply the frequency for each interval by its corresponding midpoint and add them together to find the sum
f * m for first interval: (2 * 11) = 22
f * m for second interval: (3 * 14) = 42
f * m for third interval: (8 * 17) = 136
f * m for fourth interval: (4 * 20) = 80
Sum of f * m for each interval: 22 + 42 + 136 + 80 = 280
Step 4: Finally, we divide the sum of f * m for each interval by the sum of f to find the mean:
280 / 17 = 16.47058824 = 16.47

O is the center of the regular nonagon below. Find its area. Round to the nearest tenth if necessary.
Answer:
471.1 square units
Step-by-step explanation:
A regular nonagon is a 9-sided polygon with sides of equal length.
The apothem of a regular polygon is the distance from the center of the polygon to the midpoint of one of its sides.
Therefore, the given diagram shows a regular nonagon with an apothem of 12 units.
The side length (s) of a regular polygon can be calculated using the apothem formula:
[tex]\boxed{\begin{minipage}{5.5cm}\underline{Apothem of a regular polygon}\\\\$a=\dfrac{s}{2 \tan\left(\dfrac{180^{\circ}}{n}\right)}$\\\\where:\\\phantom{ww}$\bullet$ $s$ is the side length.\\ \phantom{ww}$\bullet$ $n$ is the number of sides.\\\end{minipage}}[/tex]
Given values:
a = 12n = 9Substitute the given values into the formula to create an expression for the side length (s):
[tex]12=\dfrac{s}{2 \tan\left(\dfrac{180^{\circ}}{9}\right)}[/tex]
[tex]12=\dfrac{s}{2 \tan\left(20^{\circ}\right)}[/tex]
[tex]s=24 \tan\left(20^{\circ}\right)[/tex]
The standard formula for an area of a regular polygon is:
[tex]\boxed{\begin{minipage}{6cm}\underline{Area of a regular polygon}\\\\$A=\dfrac{n\cdot s\cdot a}{2}$\\\\where:\\\phantom{ww}$\bullet$ $n$ is the number of sides.\\ \phantom{ww}$\bullet$ $s$ is the length of one side.\\ \phantom{ww}$\bullet$ $a$ is the apothem.\\\end{minipage}}[/tex]
Substitute the found expression for s together with n = 9 and a = 12 into the formula and solve for A:
[tex]A=\dfrac{9 \cdot 24 \tan(20^{\circ}) \cdot 12}{2}[/tex]
[tex]A=1296\tan(20^{\circ})[/tex]
[tex]A=471.705423...[/tex]
[tex]A=471.7\; \sf square\;units\;(nearest\;tenth)[/tex]
Therefore, the area of a regular nonagon with an apothem of 12 units is 471.1 square units, rounded to the nearest tenth.

connect a cable between chairs B and J, and then
continue that cable to chair G. What is the angle
formed by the cable?
The angle formed by the cable between chairs B and J, and then
continue chair G is
75 degrees
How to determine the angleThe angle is determined with the knowledge of the total angle in a circle which is 360 degrees. Also, intercepted arc = 2 * inscribed angle
Assuming each chair is equal distance apart, then they will subtend equal angle.
The number of chairs for A to L is 12
angle per chair = 360 / 12 = 30 degrees
number of chairs from B to G = 5 and angle intercepted arc = 30 * 5 = 150 degrees
Inscribed angle = 1/2 * intercepted arc
Inscribed angle = 1/2 * 150

2√12
The value of sinθ is √24/7 meanwhile the correct answer is not in the option provided or perhaps option (b) is meant to be √24/7 instead.
Understanding Quadrant in TrigonometryIn the third quadrant, both the x-coordinate (cosine) and the y-coordinate (sine) of the angle are negative.
Given that
cosθ = 5/7
we can determine the value of sinθ using the Pythagorean identity:
sin²θ + cos²θ = 1
sin²θ + (5/7)² = 1
sin²θ + 25/49 = 1
Now, let's solve for sinθ:
sin²θ = 1 - 25/49
sin²θ = 49/49 - 25/49
sin²θ = 24/49
Taking the square root of both sides, we find:
sinθ = √(24/49)
Simplifying further:
sinθ = √24 / √49
sinθ = √24 / 7

Idaho gets out and closes the door behind her. She is in a room with one exit, and the lock requires a key. There's a table with a briefcase that is also locked. It has a three-digit combination. The first part of the combination is on a wheel with all 10 digits. The second wheel has only 5 digits, and the third has 3 digits. How many combinations are possible?
Answer:
150
Step-by-step explanation:
To determine the number of possible combinations for the briefcase, we need to multiply the number of options for each wheel.
The first wheel has 10 digits, so there are 10 possibilities.
The second wheel has 5 digits, so there are 5 possibilities.
The third wheel has 3 digits, so there are 3 possibilities.
To calculate the total number of combinations, we multiply the possibilities for each wheel:
10 × 5 × 3 = 150
Therefore, there are 150 possible combinations for the briefcase.
Answer: 150
Step-by-step explanation:
I’m not completely sure, but this is going by my logic. The first one has ten digits and any of those ten digits could go with 1 digit from the 5 wheel, and 1 digit from the 3 wheel, so (I think) you have to multiply 10x5x3 to get the amount of possible combinations.

The formula for the surface area of a cylinder SA= 2mth + 2rr² is 525 cm².
To find the surface area of the cylindrical can, we need to use the formula:
SA = 2π[tex]r^2[/tex]+ 2πrh
where r is the radius of the circular base of the can, h is the height of the can, and π is a mathematical constant approximately equal to 3.14.
From the given dimensions, we know that the radius of the can is 4 cm. However, we do not have the height of the can. Therefore, we cannot accurately calculate the surface area of the can.
Based on the answer choices provided, we can approximate the surface area of the can by using the given value of r = 4 cm and an estimated value for the height.
For example, if we assume the height of the can is approximately 10 cm, then we can use the formula to calculate the surface area:

Answer:
(b) $3564.54
Step-by-step explanation:
You want the new balance showing on a credit card statement if the APR is 27.99%, the old balance is $3109.87, a payment of $159 was made, and purchases were made totaling $532.42.
SubtotalApparently, the new balance is computed by subtracting payments, and adding new charges to the old balance, then computing and adding the finance charge on this sum.
balance before finance charge: $3109.87 -159.00 +532.42 = $3483.29
Finance chargeThe finance charge is 1 month's interest at the annual rate:
I = Prt = $3483.29×0.2799×(1/12) = $81.25
New BalanceThe new balance is the subtotal above, with the finance charge added:
new balance = $3483.29 +81.25 = $3564.54
Kyle's new balance will be $3564.54.
__
Additional comment
This is a very expensive credit card. Not only is the interest rate of 27.99% very high, but also finance charges are charged on new purchase in the month they are purchased.
Some cards these days have interest rates of 12.75% or lower, with no finance charge for purchases made during the month. Some cards offer a rebate of up to 1.5% of purchases, so a net "negative" finance charge if you pay off the card every month.

$16,000 is deposited into a savings account with an annual interest rate of 2% compounded continuously. How much will be in the account after 4 years? Round to the nearest cent.
The amount in the account after 4 years, rounded to the nearest cent, will be approximately $17,332.8.
Understanding Compound InterestRecall the compounding formula:
A = P * [tex]e^{rt}[/tex]
Where:
A = Final amount in the account
P = Initial principal (deposit)
e = Euler's number (approximately 2.71828)
r = Annual interest rate (as a decimal)
t = Time in years
Given:
Initial principal (P) = $16,000
Annual interest rate (r) = 2% = 0.02
time (t) = 4 years.
Substitute these values into the formula, we get:
A = $16,000 * [tex]e^{0.02 * 4}[/tex]
Using a calculator, we can calculate:
A = $16,000 * [tex]e^{0.08}[/tex]
A = $16,000 * 1.0833
A = $17,332.8
Therefore, the amount in the account after 4 years, rounded to the nearest cent, will be approximately $17,332.8.

side length of titles are 2ft. Rachel tiled the whole floor with 6 rows of 4 tiles
what is the area of the kitchen floor
The area of the rectangular shaped kitchen floor is A = 96 feet²
Given data ,
The side length of each tile is 2ft, then the area of each tile is:
Area of a tile = side x side = 2ft x 2ft = 4 sq ft
Since there are 6 rows of tiles, each row has 4 tiles, therefore the total number of tiles is:
Total number of tiles = 6 x 4 = 24 tiles
So, the total area covered by the tiles is:
Total area covered by tiles = Area of a tile x Total number of tiles
= 4 sq ft/tile x 24 tiles
= 96 sq ft
Hence , the area of the kitchen floor is 96 feet²

A bag consists of 5 marbles. There is 1 yellow, 1 red marble, 1 clear marble, 1 green marble, and 1 blue marble. Which table shows the sample space for choosing 2 marbles from the bag with replacement? Answer by looking at the images below!
Table C shows the sample space for choosing 2 marbles from the bag with replacement. The probabity and there are 25 possible pairs.
The sample space for choosing 2 marbles from the bag with replacement consists of all possible pairs of marbles that can be chosen, where the order in which they are chosen does not matter.
Since there are 5 marbles in the bag and we are choosing 2 of them, there are 5 choices for the first marble and 5 choices for the second marble, for a total of [tex]5*5 = 25[/tex] possible pairs.
Table C shows the sample space for choosing 2 marbles from the bag with replacement. Each row and column in the table represents a different marble that can be chosen, and each cell represents a pair of marbles that can be chosen.
For example, the cell in row 2 and column 3 represents the pair of marbles consisting of the red marble and the clear marble. Tables A and B show the sample space for choosing 2 marbles from the bag without replacement. In this case, the order in which the marbles are chosen does matter, and each marble can only be chosen once.
Therefore, there are only 5 choices for the first marble, but only 4 choices for the second marble (since one marble has already been chosen), for a total of[tex]5 * 4 = 20[/tex] possible pairs.
