PLEASE HELP!!!! While observing the fare meter in a taxi, a student records the following data:
Reading on Taxi Fare Meter
Time (minutes) Meter Reading
0 $7.75
10 $13.25
20 $18.75
30 $24.25
What is the equation that relates the cost, C(t), of the taxi ride and time, t, in minutes? What is the cost of a 42-minute taxi ride? (7 points)
C(t) = 0.55t + 7.75, $30.85
C(t) = 1.71t + 7.75, $79.57
C(t) = 0.775t + 5.50, $38.05
C(t) = 5.5t + 0.775, $231.78
Answer:
C(t) = 0.55t + 7.75, $30.85
Step-by-step explanation:
the fixed cost is $7.75. this is the cost incurred at zero minutes of the taxi ride
the variable cost or the cost per minutes driven =
(13.25 - 7.77) / (10 - 0) = 0.55
total cost = 7.75 + 0.55t
cost of 42 minutes = 7.75 + 0.55(42) = $30.85

Find the ordered pair that is a member of both -2x + 6y = 34 and
2x + 2y = 14 or indicate if it does not exist or there are infinite
possibilities.
Answer:
(1, 6) is the solution
Step-by-step explanation:
-2x + 6y = 34
2x + 2y = 14; divide by 2
x + y = 7; subtract x
y = 7 - x
let's substitute y with 7 - x in first equation
-2x + 6*(7 - x) = 34; expand multiplication
-2x + 6*7 - 6*x = 34; group
-8x + 42 = 34; subtract 42
-8x = 34 - 42 = -8; divide by -8
x = 1
y = 7 - 1 = 6
It is the only solution, as we've arrived at exact numbers.

Can someone please help me with this....im stuck.
Answer:
Step-by-step explanation:
One clue about where to start is this: the sentence describes the length by referring to the width. "The LENGTH is blah, blah, blah, the WIDTH. When that happens, choose a variable to represent the width (the quantity being referred to).
Width = w
Length IS three more than (added to) 4 times (multiplied by) the width
Length = 4w + 3
Area of a rectangle is the width multiplied by the length.
Equation: w(4w + 3) = 24
Solve.
Multiply out the left side.
4w^2 + 3w = 24
Subtract 24.
4w^2 + 3w -24 =0
This equation does not factor. Use the Quadratic Formula. One of the solutions is a negative number, so that should be rejected (width can't be a negative number).
[tex]w=\frac{-3+\sqrt{393}}{8}[/tex]
Substitute this into the expression 4w + 3 to find the length. A calculator can give you decimals for both dimensions.

Suppose you'd like to save enough money to pay cash for your next car. The goal is to save an extra $26,000 over the next 3 years. What amount must be deposited
quarterly into an account that earns 4.4% interest in order to reach your goal? Round your answer to the nearest cent, if necessary.
you would have to deposit approximately $22,807 quarterly into the account to reach your goal of saving $26,000 over the next 3 years at an interest rate of 4.4%.
Use the concept of compound interest defined as:
The interest that is computed using both the principal and the interest that has accrued during the previous period is called compound interest.
The compound interest formula is:
[tex]A = P(1 + r/n)^{(nt)}[/tex]
Where,
A is compounded amount
P is the principal amount
r is the rate of interest
n is the number of times compounding
t is time.
Given that,
Goal: Save enough money to pay cash for the next car.
Target amount: $26,000.
Timeframe: Over the next 3 years.
Interest rate: 4.4%.
Deposit frequency: Quarterly.
To calculate the amount you need to deposit quarterly to reach $26,000 over the next 3 years with an interest rate of 4.4%,
Use the formula of compound interest described above:
Where,
A = $26000
P =?
r = 4.4% or 0.044 as a decimal
n = 4
t = 3 years
Substituting the given values, we get:
[tex]26,000 = P(1 + 0.044/4)^{4\times3}[/tex]
Simplifying further:
[tex]26,000 = P(1 + 0.011)^{12 }[/tex]
[tex]26,000 = P(1.011)^{12}\\\\26,000 = P(1.1402)[/tex]
To solve for P, divide both sides of the equation by 1.1402:
P = 26,000 / 1.1402
P ≈ 22,807
Hence, you would have to deposit approximately $22,807 quarterly into the account.

Two buildings are 30 m apart. The angle from the top of the shorter building to the top of the taller building is. The angle from the top of the shorter building to the base of the taller building is. What is the height of the taller building?
Answer:
The height of the taller building is: 51.345m
Step-by-step explanation:
Given
The question has missing details (See attachment for the illustration of the complete question)
Required
The height of the tall building
The height, a, is calculated as:
[tex]a = b +c[/tex]
To solve for b, we consider the upper half of the attached image
The upper half is a right triangle.
Using tan formula, we have:
[tex]tan(31) = \frac{b}{30}[/tex]
Solve for b
[tex]b = 30 * tan(31)[/tex]
To solve for c, we consider the lower half of the attached image
Using tan formula, we have:
[tex]tan(48) = \frac{c}{30}[/tex]
Solve for c
[tex]c = 30 * tan(48)[/tex]
Recall that: [tex]a = b +c[/tex]
So:
[tex]a = 30 * tan(31) + 30 * tan(48)[/tex]
[tex]a = 30 * 0.6009 + 30 * 1.1106[/tex]
[tex]a = 18.027 + 33.318[/tex]
[tex]a = 51.345[/tex]
The coordinates of the vertices of triangle ABC are 1 -1 B 1, 4 and C 8, 4. WHat is the length in units of the line segment that connects vertex A and vertex B
Answer:
[tex]AB = 5[/tex]
Step-by-step explanation:
Given
[tex]A =(1,-1)[/tex]
[tex]B = (1,4)[/tex]
[tex]C = (8,4)[/tex]
Required
Distance between vertices A and B
To do this, we simply calculate distance AB using distance formula.
[tex]d = \sqrt{(x_1-x_2)^2 + (y_1 - y_2)^2}[/tex]
So, we have:
[tex]AB = \sqrt{(1-1)^2 + (4 - -1)^2}[/tex]
Simplify the expression the bracket
[tex]AB = \sqrt{0^2 + 5^2}[/tex]
Evaluate all squares
[tex]AB = \sqrt{0 + 25}[/tex]
[tex]AB = \sqrt{25}[/tex]
Take positive square root
[tex]AB = 5[/tex]
Hence, the line segment that connects A and B is 5 units long.
Billy Bob has 23 coins that total $1.70. He found some nickels and dimes in the couch.
How many nickels and dimes did he find?
Answer:
12 nickels
11 dimes
Step-by-step explanation:
Let n = no. of nickels
d = no. of dimes
5n = value of nickels in cents
10d = value of dimes in cents
170 = total value in cents
(1) n + d = 23 (2) 5n + 10d = 170
d = 23 - n 5n + 10(23 - n) = 170
5n + 230 - 10n = 170
- 5n = - 60
n = 12 nickels
d = 23 - 12 = 11 dimes
Check: 12(5) + 11(10) = 60 + 110 = 170 cents or $1.70

Step-by-step explanation:
The system of linear equations in two variables is ,
[tex]\begin{cases} x = 9y \cdots (i)\\ x - 5y = 20\cdots (ii) \end{cases}[/tex]
We can easily solve out this Question using substitution method . For that , substituting x = 9y from equation (i) to equation (ii) , we have ,
[tex]\implies x - 5y = 20 \\\\\implies 9y - 5y = 20 \\\\\implies 4y = 20 \\\\\implies y =\dfrac{20}{4}\\\\\implies\boxed{\boxed{ y = 5 }}[/tex]
Substituting this value in (i) ,
[tex]\implies x = 9y \\\\\implies x = 9\times 5 \\\\\implies \boxed{\boxed{ x = 45 }}[/tex]
Answer: (45,5)
Step-by-step explanation:
You're given what x equals: 9y. Substitute that into the equation x - 5y = 20. Your equation should look like this: 9y - 5y = 20. From there, solve for y. 9y subtracted by 5y is 4y. Then, solve 4y = 20. Divide both sides of the equation by 4. The result is y = 5. We now know the y-coordinate in the ordered pair. Substitute this y-value into the first equation: x = 9y. 9(5) = 45. x = 45.
Plug these two values into the ordered pair (x,y).

What is the difference between the cost of 15 visits with and without a membership? Show your work swimming
Question is incomplete :
It costs $4 to go to the swimming pool
The cost of n visits =
Membership at the pool costs $21. Members pay $3 each time. WHAT is The cost for a member to swim including membership fee?
What is the difference between the cost of 15 visits with and without a membership?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Swimming cost = $4
Cost of swimming n Times = cost per swim * number of swims
= $4 * n
= $4n
Membership cost = $21
Cost per swim for members = $3
Swimming cost including membership fee :
21 + 3n ; n = number of visits
For 15 visits ; n = 15
Amount paid :
Members = 21 + 3(15) = 21 + 45 = $66
Non - Member = 4(15) = 60
Difference :
$66 - 60 = 6
Members incur $6 more than non - members
ms. van rock's favourite part of pizza is the crust. which size pizza should she get to get 37.68 inches of crust?
Answer:
The 12'' one.
Step-by-step explanation:
The crust is at the perimeter of the pizza, and the pizza is a circle, so we just need to calculate the perimeter of the different pizza sizes, and see which one has a perimeter of 37.68 in.
First, you should remember that for a circle of radius R, the perimeter is:
P = 2*3.14*R
(notice that the measures in the image are the diameters of the pizzas, and the radius is half of the diameter)
The radius that we need to have if we want a perimeter of 37.68 in is given by:
P = 37.68 in = 2*3.14*R
(37.68 in)/(2*3.14) = R = 6 inches.
Then we need a pizza of 6 inches (or a diameter of 2*6 inches = 12 inches)
Then the pizza that Ms. Van Rock should get is the 12 inch one.

The required value of the missing sides with the help of trig ratios we have x = 19.9.
What are trig ratios?If you know the lengths of two sides of a right triangle, you can use trigonometric ratios to calculate the measures of one (or both) of the acute angles.
Here,
To find the missing side in the given right triangle, we can use trigonometric ratios. Specifically, we can use the tangent ratio:
Cosine of an angle = opposite side / adjacent side
In this case, we know the measure of one acute angle (19 degrees) and the length of the adjacent side (21). We want to find the length of the opposite side, which we can represent as x.
cos(19°) = x / 21
Multiplying both sides by 21, we get:
x = 21 cos(19°)
Using a calculator, we can evaluate the right-hand side to get:
x ≈ 19.85
Rounding to the nearest tenth, the missing side is approximately 19.9 units long.
