You are trying to decide whether to use Uber or Lyft during a vacation. Uber charges $3 to pick up plus an additional $0.25 for each mile driven. Lyft does not charge to pick up but they have a rate of $0.75 for each mile driven.
Let x = the number of miles traveled and y = the total cost for the trip.
Will the cost of the two companies ever be the same? If so, at how many miles and what is that cost? If not, explain your reasoning. Show all work that leads to your answer.
Answer:
6 Miles and the cost is $4.50
Step-by-step explanation:
3+0.25=0.75x
3+0.50x
6=x
0.75x+?
0.75 x 6= 4.50

Whats the surface area?
Answer:
Total Area = 1070 m^2
Step-by-step explanation:
we have 4 different surfaces
the "ramp" the triangles (2) one for each sidethe bottom rectanglethe back rectangle1. the ramp
[tex]A_r = 15\times 30\\\\A_r = 450[/tex]
2. the triangles
since they are the same we just multiply by two
[tex]A_t = \frac{8\times 10}{2}\\\\A_t = \frac{80}{2}\\\\A_t = 40[/tex]
so the areas of the two triangles is
[tex]2A_t = 2(40)\\\\2A_t = 80[/tex]
3. the bottom rectangle
[tex]A_{bot} = 10\times 30\\\\A_{bot} = 300[/tex]
4. the back rectangle
[tex]A_{back} = 8\times 30\\\\A_{back} = 240[/tex]
now add them together
[tex]A_T=A_r+2A_t+A_{bot}+A_{back}\\\\A_T = 450+80+300+240\\\\A_T = 1070\: m^2[/tex]
I need 4 1/2 teaspoons of butter but i only have 1/8 measuring cup how many 1/8 of butter do i need?
Answer:
2 1/2
Step-by-step explanation:
Answer:
36 cups
Step-by-step explanation:
You only have ⅛ measuring cup. Now, since you need 4½ teaspoons of butter, the number of ⅛ measuring cups needed to achieve that will be;
4½ ÷ ⅛ = 9/2 × 8/1 = 36 cups
Thus, you will need 36 number of ⅛ cups

What is probability?Probability is the measure of the likelihood that an event will occur in a Random Experiment. Probability is quantified as a number between 0 and 1, where, loosely speaking, 0 indicates impossibility and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur.
Given:
Joe is shown 3 cards marked 2, 5 and 9.
we have write all the possible 3digit numbers
First taking 2 at hundred place value
259
295
Now, taking 5 at hundred place value

Reasoning How would the graph of y = - 3x + 2 change if - 3 were replaced by 4? How would it change if were replaced by 0? Explain.
Answer:
Please check the attached diagram.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptAnalysis of y = - 3x + 2
Given the linear function
y = - 3x + 2
comparing with the slope-intercept form y = mx+b
The slope m = -3
The negative slope indicates that as the line on the line graph moves from left to right, the line falls.
In other words, the negative slope indicates that when x increases, y decrease, and vise versa.
Please check the attached graph of the function y = - 3x + 2. It is clear that when x increases, y decreases, hence the line falls when the graph of the line moves from left to right.
The red line graph represents the linear function y = - 3x + 2.
Analysis of y = 4x + 2 (When -3 is replaced by 4)
Now, when we replace -3 by 4 in the equation y = - 3x + 2, the equation becomes
y = 4x + 2
comparing with the slope-intercept form y = mx+b
The slope m = 4
The positive slope indicates that as the line on the line graph moves from left to right, the line rises.
In other words, the positive slope indicates that when x increases, y also increases, and vise versa.
Please check the attached graph of the function y = 4x + 2. It is clear that when x increases, y increases, hence the line rises when the graph of the line moves from left to right.
The blue line graph represents the linear function y = 4x + 2.
Analysis of y = 2 (When -3 is replaced by 0)
Given the equation
y = - 3x + 2
If we replace -3 by 0, the equation becomes
y = 0x + 2
y = 2
In other words, y = 2 represents a horizontal line because the horizontal line is of the form
y = k
where k is the y-intercept
here k = 2 is the y-intercept of the line y = 2.
Thus, slope zero means the value of y does not change no matter what we take or change the x-value.
The graph of line y = 2 is also attached which represents a horizontal line with slope 0 and y-intercept 2.
The green line graph represents the linear function y = 2.
Please check the graphs of all the lines.

−4x−24x+24=10(12−2x) explain how you sloved it...i rllly need this!!!!
Answer:
x=-12
Step-by-step explanation:
first collect all the like terms -28x + 24 = 120-20x
then move variables and constants to the correct side -28x + 20x = 120-24
collect like terms again -8x = 96
divide both side by -8 so -8x/-x n 96/-8 you get x=-12 bc -8 time -12 = 96
Answer:
x = -12
Step-by-step explanation:
First, combine like terms
[tex]-4x-24x+24 = 10(12-2x)\\-28x+24 = 10(12-2x)[/tex]
Then, use the distributive property on the right side
[tex]-28x + 24 = 120 - 20x[/tex]
Now, add 28x to both sides to get the Xs all together
[tex]24 = 120 + 8x[/tex]
Next, subtract 120 from both sides:
[tex]-96 = 8x[/tex]
divide both sides by 8:
[tex]-12 = x[/tex]
This means the answer is x = -12

or X
Step-by-step explanation:
4x³ = 36x
4x³ - 36x = 0

Multiply: (7y^3/5)(6x+5/21y)
Answer:
y²(6x+5)/15Step-by-step explanation:
We are to multiply the expression (7y^3/5)(6x+5/21y)
(7y^3/5)(6x+5/21y) = 7 * y * y * y/5 * 6x+5/21y
(7y^3/5)(6x+5/21y) = y²/5 * 6x+5/3
(7y^3/5)(6x+5/21y) = y²(6x+5)/5*3
(7y^3/5)(6x+5/21y) = y²(6x+5)/15
Hence the product is y²(6x+5)/15

Given
y = 2x + 1 .....i)
y = 3x +2 .....ii)
Putting equation II in equation i
3x + 2 = 2x + 1
3x - 2x = 1 - 2
x = -1
Now putting x = -1 in equation i
y = 2* (-1) + 1
= -2 + 1
= - 1
Therefore x = -1 and y = -1

The sum of the measures of three adjacent angles is 150' The measures of the angles are in the ratio of 1:2:3. What is the measure, in degrees of the
largest angle?
The measure of the largest angle is
degrees
Answer:
It is a 30, 60, 90 triangle.
Step-by-step explanation:
Hence, the measure of the largest angle is degrees is [tex]5[/tex] degree, [tex]10[/tex] degree and [tex]15[/tex] degree and the largest angle is [tex]15[/tex] degree.
What are the angles?
Angles are formed by two rays (or lines) that begin at the same point or share the same endpoint. The point at which the two rays meet (intersect) is called the vertex.
Here given that,
The sum of the measures of three adjacent angles is [tex]150[/tex] degree. The measures of the angles are in the ratio of [tex]1:2:3.[/tex]
Let one angle is [tex]x[/tex], second is [tex]2x[/tex] and the thirs one is [tex]3x[/tex].
As given that the sum of three angles is [tex]150[/tex] degree but we know that the sum of three angles is [tex]180[/tex] degree then,
[tex]x+2x+3x=180-150\\\\x+2x+3x=30\\\\6x=30\\\\x=\frac{30}{6}\\\\x=5[/tex]
when
[tex]x=5\\\\2x=2(5)\\\\2x=10[/tex]
when
[tex]x=5\\\\3x=3(5)\\\\3x=15[/tex]
Hence, the measure of the largest angle is degrees is [tex]5[/tex] degree, [tex]10[/tex] degree and [tex]15[/tex] degree and the largest angle is [tex]15[/tex] degree.

1) A triangular prism has a base measuring 8 inches and a side measuring 5
inches. It has a depth of 3 inches. What is the volume?*
O
40 cubic inches
O 20 cubic inches
O 24 cubic inches
60 cubic inches
Answer:
24 cubic inches
Step-by-step explanation:
Whenever you are finding the volume you have to multiply by two plus a number times two. For example, since there is two depths, you have to multiply 3 by 2 plus the next number. Then, since there is two sides, you multiply 5 by 2 plus the next number. Finally, since there is only one base, you don't have to multiply by two.
(3×2)+(5×2)+8=24
