The cost of a taxi ride can be modeled as a function of the number miles traveled. There is a base charge of $3.50 and also a charge of $0.10 per mile. A- Write an equation to describe this scenario B- What does the independent variable represent? C- What does the dependent variable represent? D- What is the rate of change in this scenario?
Answer:
a. C(x) = $3.50 + $0.10x. b. distance traveled c. cost of the taxi ride d. $0.10 per mile
Step-by-step explanation:
A. Let C be the cost of the taxi ride and x be the distance traveled in miles. Since there is a base charge of $3.50 and a charge of $0.10 per mile, the cost of the ride is thus
C(x) = $3.50 + $0.10x.
B. The independent variable represents the distance traveled in miles since it is the parameter being measured.
C. The dependent variable represents the cost of the taxi ride, since it is value depends on the parameter (the distance) being measured.
D. The rate of change in this scenario is the $0.10 per mile
Carson runs a farm stand that sells strawberries and bananas. Each pound of
strawberries sells for $3 and each pound of bananas sells for $1.50. Carson sold 4
times as many pounds of strawberries as pounds of bananas and he made $135
altogether. Graphically solve a system of equations in order to determine the number
of pounds of strawberries sold, 2, and the number of pounds of bananas sold, y.

Answer:
40 lb strawberries10 lb bananasStep-by-step explanation:
See below for the graph of the equations ...
3x +1.50y = 135 . . . . total from sales
x = 4y . . . . . . . . . . . . strawberry pounds are 4 times banana pounds
The solution is ...
(x, y) = (40, 10)
40 pounds of strawberries and 10 pounds of bananas were sold
Answer: There were 40 pounds of strawberries sold and 10 pounds of bananas sold.
Step-by-step explanation:
x=the number of pounds of strawberries sold
y=the number of pounds of bananas sold
3x+1.50y=135 (0,90) (45,0)
x=4y (20,5) (40,10)
(40,10)

Appreciate all the support.
(Explanation would be thankful A LOT )
Answer:
[tex]f(n) = 3n[/tex]
Step-by-step explanation:
Given
f(n) --- yards
n --- feet
Required
Write the function rule
From conversion from yard to feet...
We have:
[tex]1\ yard = 3\ feet[/tex]
Multiply both sides by n
[tex]n * 1\ yard = 3\ feet * n[/tex]
[tex]n\ yard = 3n\ feet[/tex]
Replace n yard with f(n)
[tex]f(n) = 3n[/tex]

Whats a good explanation for a bag contains 120 marbles. Some are red and the rest are black. There are 19 red marbles for every black marble. How many red marbles are in the bag?
Answer: 114 marbles
Step-by-step explanation:
From the question, we are told that a bag contains red and black marbles which are 120 marbles in total. We are further told that there are 19 red marbles for every black marble.
Let the number of black marbles be represented by a.
The red marbles will be: = 19 × a = 19a
Based on the information given in the question,
Black marbles + Red marbles = 120
a + 19a = 120
20a = 120
a = 120/20
a = 6
Black marbles = 6
Red marbles = 19a = 19 × 6 = 114 marbles

Question Help Use the GCF and the Distributive Property to find the sum. 42 + 66 Write each number as a product using the GCF as a factor, and apply the Distributive Property. 42 + 66 = (Use the operation symbols in the math palette as needed. Do not simplify.)
Answer:
40 plus (2)42 plus 6x11
Step-by-step explanation:
Multiply
Using GCF and Distributive property on the sum of 42 and 66 gives us;
((6 * 7) + (6 * 11) = 6(7 + 11)
GCF simply means the greatest common factor. Now, to find the GCF of 42 and 66, let us state their factors;
Factors of 42 = 1, 2, 3, 6, 7, 14, 21, 42
Factors of 66 = 1, 2, 3, 6, 11, 22, 33, 66
The highest factor common to 42 and 66 is 6. Thus, we can say that the GCF of 42 and 66 is 6.
We want to add 42 to 66.42 + 66
The distributive property states that;
a(b + c) = ab + ac
Thus;
Since GCF of 42 and 66 is 6, then we have;
42 + 66 = ((6 * 7) + (6 * 11)
Using distributive property;
((6 * 7) + (6 * 11) = 6(7 + 11)

what does Instantenous Rate Of Change find
Answer:
The instantaneous rate of change is the change in the rate at a particular instant, and it is same as the change in the derivative value at a specific point. For a graph, the instantaneous rate of change at a specific point is the same as the tangent line slope.

Answer:
6,300,000,000,000,000
Step-by-step explanation:
First, you want to find out much the answer will be for the powers. That means doing 10 to the 8th power and 10 to the 6th power. Once you get that, put it aside. Next, you want to go ahead and multiply 7 and 9. After you do that all you will have left is 100000000 x 1000000 x 63. Last, all you have to do is multiply 100000000 by 1000000 and that's easy because all you have to do is add the 0's and end up getting 100000000000000. Now, all you do is multiply that by 63 and you get 6,300,000,000,000,000. Hope this was helpful.

Casey went to the store and purchase case 12 pairs of socks.And 3 pairs of shoes for 18.20 each. She spent a total of 81.60. How much did she pay for each sock
Answer:
Casey paid 2.25 in the required currency for each pair of socks.
Step-by-step explanation:
Casey spent a total of $81.60 on both 12 pairs of socks and 3 pairs of shoes.
A pair of shoe = 18.20, then;
3 pairs of shoe = 3 x 18.20
= 54.60
The amount spent on socks = total amount - amount spent on shoes
= 81.60 - 54.60
= 27.00
So that,
The price of each pair of socks = [tex]\frac{amount spent on socks}{number of pairs}[/tex]
= [tex]\frac{27}{12}[/tex]
= 2.25
Casey paid 2.25 in the required currency for each pair of socks.

Customers at the gym pay a membership fee to join and then a fee for each class they attend. Here is a graph that represents the situation.
•what does the slope of the line shown by the points mean in this situation?____
•what does the vertical intercept mean in this situation?_____
Answer:
Step-by-step explanation:
Customers at the gym pay a membership fee and fee for each class they attend.
From the graph attached,
- Slope of the line shown by the points means, fee per class paid by the customers.
- Vertical intercept means the membership fee to join the gym.
The slope means that each class cost $20, while the vertical intercept mean that the membership fee is $60.
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the rate of change and b is the y intercept.
Let y represent the total fee paid for undergoing x classes.
The graph passes through the point (0, 60) and (6, 180). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-60=\frac{180-60}{6-0}(x-0)\\\\y=20x+60[/tex]
The slope means that each class cost $20, while the vertical intercept mean that the membership fee is $60.

from her monthly paycheck for Social Security and Medicare
taxes. What is her monthly salary?
Solution
Step-by step
Answer: $6500
Step-by-step explanation:
An employee pays 6.2% as social security and 1.45% as Medicare and the company pays the remaining 7.65%.
Therefore, a total of (6.2% + 1.45%) = 7.65% is deducted from the person income.
Let the monthly salary of Nancy be a
7.65% × a = $497.25
