Answer:
[tex]Total\ Rent = 49 + 5m[/tex]
Step-by-step explanation:
Given
Rent per day = $49
Addition = 5 cents per mile
Required
Determine the rent for a day and m miles
First, we need to generate a formula from the given parameters;
Let d represent number of days and m represent additional miles;
[tex]Total\ Rent = 49 * d + 5 * m[/tex]
[tex]Total\ Rent = 49 d + 5 m[/tex]
Solving for the rent for a day and m miles
We have that: d = 1 and m = m
Substitute these in the formula above
[tex]Total\ Rent = 49 * 1 + 5 * m[/tex]
[tex]Total\ Rent = 49 + 5m[/tex]
Hence, the total rent is
[tex]Total\ Rent = 49 + 5m[/tex]
Select the statement that accurately describes the following pair of
triangles
Answer:
5. Triangle UVT ~ ∆RSQ by SSS
Step-by-step explanation:
The ratios of side lengths, shortest to longest are ...
VT : TU : UV = 42 : 70 : 84 = 3 : 5 : 6
SQ : QR : RS = 15 : 25 : 30 = 3 : 5 : 6
Side lengths are proportional, so ∆UVT ~ ∆RSQ.
__
The triangle names need to be chosen so the sides are in the same order. Here UV and RS correspond, as do VT and SQ. That eliminates all but one answer choice.

This is the square root of 6 over 3. The 3 is not inside the square root.
========================================================
Explanation:
sqrt = square root
We have sqrt(6) in the denominator. Your teacher wants you to rationalize the denominator, which means to take out the square root and instead have an integer here.
To achieve this, we multiply top and bottom of the fraction by sqrt(6) like so
[tex]\frac{2}{\sqrt{6}}\\\\\frac{2*\sqrt{6}}{\sqrt{6}*\sqrt{6}}\\\\\frac{2\sqrt{6}}{\sqrt{6*6}}\\\\\frac{2\sqrt{6}}{\sqrt{36}}\\\\\frac{2\sqrt{6}}{6}\\\\\frac{2\sqrt{6}}{2*3}\\\\\frac{\sqrt{6}}{3}\\\\[/tex]
Therefore,
[tex]\frac{2}{\sqrt{6}}=\frac{\sqrt{6}}{3}\\\\[/tex]

how do you solve this system of equation?
2x+4y=-4
3x + 5y =-3
Answer:
x = 4
y = -3
Step-by-step explanation:
We can use substitution, elimination, or graphically.
Step 1: Rearrange first equation
2x + 4y = -4
2x = -4 - 4y
x = -2 - 2y
Step 2: Rewrite systems of equations
x = -2 - 2y
3x + 5y = -3
Step 3: Substitution
3(-2 - 2y) + 5y = -3
-6 - 6y + 5y = -3
-6 - y = -3
-y = 3
y = -3
Step 4: Find x using y
2x + 4(-3) = -4
2x - 12 = -4
2x = 8
x = 4
Graphically:
Use a graphing calc and analyze where the 2 lines intersect.

Answer:
[tex]x = \frac{40}{6} [/tex]Step-by-step explanation:
To solve the equation
(2x - 1) + (4x + 9) = 32
First of all remove the parenthesis
That's
2x - 1 + 4x + 9 = 32
Simplify
We have
6x - 8 = 32
Add 8 to both sides
Thats
6x - 8 + 8 = 32 + 8
6x = 40
Divide both sides by 6
That's
[tex] \frac{6x}{6} = \frac{40}{6} [/tex]
We have the final answer as
[tex]x = \frac{40}{6} [/tex]

Scientists believe there is a link between ambient temperature and damage to a head gasket on a car. Using the provided information, draw a scatterplot of the data. Based on the information, what might the approximate damage index be if the temperature was 10° Celsius? A) 5 B) 7 C) 10 D) 13
Answer:
D) 13
Step-by-step explanation:
The lower temperatures have a negative correlation so the lower the temperature the higher the damage index. Therefore a temperature of 10° Celsius should have a damage index higher than that of 12° Celsius so the only option is 13.

What are the solutions of |3x + 2| > 9?
Absolute value means the distance the number zero.
(3x+2) is (3x+2) from 0.
So right now, 3x+2>9, you have to get rid of the 2 on the left side (because you don't want the variable and the constant on the same side) .
Subtract 2 from the left side and 2 from the right.
Now it is 3x > 9-2
9-2=7

There are 7 students in a class. If there are 3 seats in the front row, how many ways can the students sit in the front row, assuming there are no empty seats?
Answer:
35 different waysStep-by-step explanation:
Since there are 7 students in a classroom to fill a front row containing 3 seats, we will apply the combination rule since we are to select 3 students from the total number of 7 students in the class.
In combination, if r objects are to be selected from a pool of n objects, this can be done in nCr number of ways.
nCr = n!/(n-r!)r!
Selecting 3 students from 7 students to fill the seats can therefore be done in 7C3 number of ways.
7C3 = 7!/(7-3)!3!
7C3 = 7!/(4)!3!
7C3 = 7*6*5*4!/4!*3*2
7C3 = 7*6*5/6
7C3 = 7*5
7C3 = 35
Hence there are 35 different ways that the student can sit in the front assuming there are no empty seats.

Answer:
D) 10000 feet
Step-by-step explanation:
We are told that for some actual altitude, the reading is ...
30,000 ft = (1 -25%)altitude = 0.75×altitude
Multiplying by 4/3, we have ...
(4/3)(30,000 ft) = altitude = 40,000 ft
To get to 30,000 ft, the plane must descend ...
40,000 ft -30,000 ft = 10,000 ft

What is the equation for the line through P that is parallel to L and perpendicular to L. P(0,0), L:y=-x+2
Answer:
A. The equation of the line parallel to line L is y = – x
B. The equation of the line perpendicular to line L is y = x
Step-by-step explanation:
We'll begin by calculating the slope of line L.
This can be obtained as follow:
y = –x + 2
Comparing the above equation with:
y = mx + c
We can see that the slope (m) = –1.
Therefore, the slope of line L is –1
A. Determination of the equation of the line parallel to line L. This is illustrated below:
When two lines are parallel, their slope (m) is equal i.e
m1 = m2
m1 = – 1
– 1 = m2
This means that the slope of the line parallel to line L is –1
Now we shall determine the equation of the line parallel to line L as follow:
Coordinate = (0, 0)
x1 coordinate = 0
y1 coordinate = 0
Slope (m) = –1
y – y1 = m(x – x1)
y – 0 = –1 (x – 0)
y = – x
Therefore, the equation of the line parallel to line L is y = – x
B. Determination of the equation of the line perpendicular to line L. This is illustrated below:
When two lines are perpendicular, the product of their slope (m) is –1 i.e
m1 • m2 = – 1
but m1 = –1
–1 x m2 = – 1
Divide both side by – 1
m2 = –1/–1
m2 = 1
Now, we shall determine the equation of the line perpendicular to line L as follow:
Coordinate = (0, 0)
x1 coordinate = 0
y1 coordinate = 0
Slope (m) = 1
y – y1 = m(x – x1)
y – 0 = 1 (x – 0)
y = x
Therefore, the equation of the line perpendicular to line L is y = x

She gained weight in fourth week = [tex]\dfrac34[/tex] pounds
She lost weight in fifth week = [tex]\dfrac38[/tex] pounds
Now, net weight she gained= [tex]\dfrac{5}{6}+\dfrac34+\dfrac34+\dfrac34-\dfrac{3}{8}[/tex]
[tex]=\dfrac{20+18+18+18-9}{24}\\\\=\dfrac{65}{24}\\\\=2\dfrac{17}{65}\text{ pounds}[/tex]

Andy painted 400 square feet in 3 hours.how long will it take him to paint 720 square feet
Answer:
324 minutes or 5.4 hours
Step-by-step explanation:
400/3 = 133.333
133.333/60 = 2.2222
It took him one minute to paint 2.2222 square feet
720/2.2222 = 324 minutes
324/60 = 5.4 hours
Answer:
It will take Andy 5 hours and 24 minutes to paint 720 sq. ft.
Step-by-step explanation:
Since he painted 400 sq. ft. in 3 hours, then do 400/3 to get 133.33... sq. ft per hour. Then, do 720 / 133.33... to get 5.40000000001 hours taken. The 5 represents 5 hours, and the .4 represents 24 minutes (because 60 x .4 = 24).
Overall, you get 5 hours and 24 minutes of time to pain 720 sq. ft.
Line g passes through the points (-2.6,1) and (-1.4,2.5), as shown. Find the equation of the line that passes through (0,-b) and (c,0).
Answer:
y=-1.25x-4.25
Step-by-step explanation:
I had the same assignment.
The equation of the line that passes through (0,-b) and (c,0) is
7y - 8x = 28
The formula for calculating the equation of a line in point-slope form is expressed as:
[tex]y-y_0=m(x-x_0)[/tex]
m is the slope of the line
(x0, y0) is any point on the line
Given the coordinate points (0, -b) and (c, 0)
Since b = -4 and c = -3.5
The required coordinate points will be (0, 4) and (-3.5, 0)
Substitute the given parameters into the given formula for calculating the slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{0-4}{-3.5-0} \\m = \frac{4}{3.5}\\m = 8/7[/tex]
Substitute m = 8/7 and the point (0, 4) into the expression [tex]y-y_0=m(x-x_0)[/tex]
[tex]y-4=\frac{8}{7} (x-0)\\7(y-4)=8x\\7y-28=8x\\7y-8x=28[/tex]
Hence the equation of the line that passes through (0,-b) and (c,0) is
7y - 8x = 28
