Paul paid $10 for a ticket to the fair and then another $2 per ride. Write an equation to show how many rides x, Paul can take if he has $40.
2x = 40
2x - 10 = 40
10x + 2 = 40
2x + 10 = 40
Answer:
D) 2x+10=40, x= 15 rides
Step-by-step explanation:
Since Paul only bought one ticket, then $10 is the constant of the equation. Since Paul pays $2 per ride, $2 will be the rate/coefficient of the equation.
Since we are solving for x, $40 will be on the right side of the equation
Putting these three facts together, we can make the equation 2x+10=40 which means D is correct
Evaluate [(40 + 5) - 3^2] divided by 9 times 2
Landon hands out 120 flyers in 2 hours. Fernando hands out 29 flysers in 30 minutes. Which equation can be used to determine the number of flyers Fernando handed out in 2 hours?
Answer:
0.5x = 48
96 flyers
Step-by-step explanation:
Given that:
Fernando hands out 29 flyers in 30 minutes ;
Number of flyers he hands out in 2 hours ;
29 flyers = 0.5 hours
Let number of flyers he hands out in 2 hours = x
Hence,
29 flyers = 0.5 hours
x = 2
0.5x = 48 flyers
x = 48 / 0.5
x = 96 flyers
A car rental agency charges 150 per week +0.45 per mile to rent car express the weekly cost to rent a car if as a function of the number of miles driven during week X
Answer:
The required function is:
[tex]C(x) = 150+0.45x[/tex]
Step-by-step explanation:
We have to represent the given scenario as an equation or function
Let x be the number of miles driven in a week
Let C(x) be the function of the number of miles driven
As it is given that charges are 150 per week, these charges are constant so they will be used as it is.
It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:
0.45x
Combining both terms, we get
[tex]C(x) = 150+0.45x[/tex]
Hence,
The required function is:
[tex]C(x) = 150+0.45x[/tex]
The cost of a car battery costs $35 wholesale for the automotive store to buy, but they need to markup the cost 40% for the retail price. How much is the markup amount? And how much is the retail price?
Answer:
The markup amount is $14 and the retail price is $49.
Step-by-step explanation:
You can use the following formula to find the retail price with the information provided:
Retail price=Cost*(100%+markup %)
Cost=35
Markup %= 40%
Now, you can replace the values in the formula:
Retail price=35*(140%)
Retail price=49
Now, you can subtract the cost from the retail price to find the markup amount:
49-35=14
According to this, the answer is that the markup amount is $14 and the retail price is $49.

5 x 28 = 140
1 week = 7 days
4 x 7 = 28
140 + 28 = 168
In order for hector to sell more than Danielle he has to sell a # of tickets that is greater then 168.
Evaluate 5 + 3x for (a) x= -2 and (b)x= 3. Write your answers in simplest form.
Answer:

Step-by-step explanation:
a.
5 + 3(-2)=
5 + (-6)=
-1
b.
5 + 3(3)=
5 + 9=
14
When x = -2, the value of 5 + 3x is -1,
and when x = 3, the value of 5 + 3x is 14.
Here, we have,
given equation is: 5 + 3x
To evaluate the expression 5 + 3x for the given values of x:
(a) When x = -2:
5 + 3(-2)
= 5 - 6
= -1
(b) When x = 3:
5 + 3(3)
= 5 + 9
= 14
Therefore, when x = -2, the value of 5 + 3x is -1,
and when x = 3, the value of 5 + 3x is 14.

Find the sum of 2√5 and 3√16 in simplest form. Also, determine whether the result is rational or irrational and explain your answer
Answer:
2√5 +12 or 16.47213595....
Step-by-step explanation:
Part A - The sum of 2√5 and 3√16 in its simplest form is 2(√5 + 6).
The given numbers are surds.
To find the sum of 2√5 and 3√16, we perform the arithmetic operation of addition on the surds.
So, 2√5 + 3√16 = 2√5 + 3 × 4 (√16 = 4)
2√5 + 3√16 = 2√5 + 12
Factorizing out the factor 2 from both expressions, we have
2√5 + 3√16 = 2√5 + 6 × 2
2√5 + 3√16 = 2(√5 + 6)
So, the sum of 2√5 and 3√16 in its simplest form is 2(√5 + 6).
Part B - The result is irrational.
The result is irrational because 2(√5 + 6) cannot be expressed as a ratio of two integers since √5 is irrational and √5 + 6 is irrational and thus 2(√5 + 6) is also irrational since it cannot be expressed as a ratio of two integers. Also, its decimal representation is non-terminating or repeating.
Thus, the result is irrational.

You set up a hot chocolate stand at a football game. The cost of your supplies is $75. You charge $0.50 for each cup of hot chocolate. Write a function that represents the profit P for selling c cups of hot chocolate.
Answer:
P = 0.5c - 75
Step-by-step explanation:
Profit is = selling price. - cost price
Cost price is the amount the supplies were bought = $75
The cost of c cups at $0.5 per cup will be
0.5 * c = $0.5c
The profit here is thus;

A rectangular box has its length and width doubled and its height tripled. The volume of the new box will be
Answer:
volume of the new box = 12 x volume of the initial rectangular box
Step-by-step explanation:
Let the length, width and height of the rectangle be represented by l, w and h respectively.
The volume of a rectangle is given as;
volume = l x w x h
= lwh
From the given question, the dimension of the rectangle are:
new length = l + l = 2l
new width = w + w = 2w
new height = h + h + h = 3h
So that, the volume of the new box is given as;
volume of the new box = 2l x 2w x 3h
= 12 (lwh)
Therefore,
volume of the new box = 12 x volume of the initial rectangular box

So for dilation when it says to dilate 1/3 how do I solve that (ex. 18, 9)
Answer:
The image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).
Step-by-step explanation:
Let suppose the given point is A(18, 9)
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruentRule to calculate the dilation by a scale factor 1/3 centered at the origin
P(x, y) → P'(1/3x, 1/3y)
Here, P'(1/3, 1/3y) is the image of P(x, y).
It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 1/3.Thus,
A(18, 9) → A'(1/3(18), 1/3(9)) = A'(6, 3)
Therefore, the image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).

Find the surface area of the prism.
The surface area is square millimeters.
Answer:
57.1mm^2
Step-by-step explanation:
4*4=16
16/2=8mm^2 cross section
(4*3) + (4*3) + (5.7*3) = 41.1mm
8*2=16
41.1+16=57.1mm^2
The surface area of the prism is S = 57.1 mm²
What is the surface area of the prism?The surface area of the prism is calculated as
The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism
Surface Area of the prism = 2B + ph
The area of the triangular prism is A = ph + ( 1/2 ) bh
Given data ,
Let the area of the 2 triangles be T
Let the area of the 2 rectangles be R
Let the area of the third side be U
Now , the total surface area of the prism = T + R + U
where T = 2 x ( 1/2 ) ( 4 x 4 )
T = 16 mm²
R = 2 x ( 3 x 4 )
R = 24 mm²
And , U = 5.7 x 3
U = 17.1 mm²
Therefore , the total surface area of prism S = 16 mm² + 24 mm² + 17.1 mm²
S = 57.1 mm²
Hence , the surface area of prism is S = 57.1 mm²

Footlocker has sale ln any three shirts for $55.50 meanwhile nike is having their own sale ln any five sale shirts for $79.99 which store offers the best deal what is your saving per shirt
Answer:
The nike store offers the best deal
The saving per shirt is $2.50
Step-by-step explanation:
Here, we want to compare the prices offered in the two stores
In footlocker, you can get 3 shirts for $55.50
The sales per shirt is thus;
55.5/3 = $18.50
For Nike,
5 shirts for $79.99 which is almost $80
So the price per shirt is $80/5 = $16
We can see that the price at the nike store is better
The difference leading to the savings is;
18.5-16 = $2.50
So you save $2.50 buying from the nike store
