Explanation:
Building the rule
The trick with algebra is to think what you would do with numbers, then substitute letters.
Mile number 1 costs
$
4.25
The rest of the miles
⇒
(
total miles

$
1.50
Putting this all together we have:
$
4.25

(
total miles

1.50
The question instructs that we are to use the letter m for the total miles so we now have:
$

Answer:
133 miles
Step-by-step explanation:
3.75 + 3 = 6.75
round to 6.80
20 - 6.80 = 13.2
13.2 / 0.1 = 132
132 + 1 the first mile that you payed $3.75
At 9:00 a.m., the wind speed at Harbor Bay was recorded. After that, the wind speed was recorded every hour. Each measurement showed an increase in wind speed of 3 miles per hour. The strongest wind was recorded at 4:00 p.m., and measured 52 miles per hour. After that, the wind speeds started to decrease. How windy was it when the experiment began?
Answer:
The wind speed was 31 miles per hour when the experiment began.
Step-by-step explanation:
Linear Dependency
The wind speed is known to increase at a rate of 3 miles per hour every hour.
From 9:00 a.m. to 4:00 p.m. there are 7 hours.
Thus, the speed increased by 7 * 3 = 21 miles per hour during that period of time.
Assuming the wind increased linearly, and its speed was measured at 52 miles per hour at 4:00 p.m., then the initial speed at 9:00 a.m. is calculated by subtracting:
52 miles / hour - 21 miles / hour = 31 miles / hour
The wind speed was 31 miles per hour when the experiment began.
Answer:
The wind speed was 31 miles per hour when the experiment began.

2. Suppose there are 6 million people in New York City that walk an average of 2.5 miles per day. If we add up all the miles walked by these 6 million how many times around the Earth would these walkers have gone? Assume the distance around the Earth is 2.5 * 10 ^ 4 miles. Write your result in scientific notation.
Answer:
600 timesStep-by-step explanation:
GivenNumber of people:
6 million = 6*10^6Distance to walk:
2.5 miles per day per personDistance around the Earth
2.5*10^4SolutionTotal distance walked:
6*10^6*2.5 = 15*10^6The ratio of total distance to the distance around the Earth:
15*10^6 / 2.5*10^4 = 6*10^2 = 600 timesNumber of people:
6 million = [tex]6[/tex] × [tex]10^{6}[/tex]
Distance to walk:
2.5 miles every day per person
Distance around the Earth
[tex]2.5[/tex] ×[tex]10^{4}[/tex]
Total distance walked:
[tex]6[/tex] × [tex]10^{6}[/tex] × [tex]2.5[/tex] [tex]= 15[/tex] × [tex]10^{6}[/tex]
The ratio of total distance to the distance around the Earth:
[tex]15[/tex] × [tex]10^{6}[/tex] / [tex]2.5[/tex] × [tex]10^{4}[/tex] = [tex]6[/tex] × [tex]10^{2}[/tex] = [tex]600[/tex]

The rental rate for a cement mixer has a flat rate of $40 plus $20 for each day of the rental. The graph shows points representing the total cost of the rental. Which linear equation, in slope-intercept form, that models the total cost of the rental over time? y = 20x +40 y = x + 50 y = 50x + 25 y = 25x y = 75x
Answer:
Step-by-step explanation:
y= 20x+40
y- is the cost of rental
x-number of days
20 is the slope
40-flat rate and the y-intercept is at (0,40)

When two parallel lines are intersected by a transversal, the same-side exterior angles are supplementary. That means that their sum is 180.
Using that logic, if the two roads were parallel, then the sum of their same-side exterior angles will add up to 180. Yet their same-side exterior angles add up to 170 (130 + 40 = 170), hence they can't be parallel.
See the drawing attached below.
Using supplmenatry angles (two angles whose sum of measures add up to 180 or a straight line), we can say that:
m<DIE + m<HID = 18
40 + m<HID = 180
m<HID = 140
Similarly:
m<BHC + m<CHI = 180
130 + m<CHI = 180
m<CHI = 50
Using verticle angles therome, (when two lines intersect, the angles opposite to eachother are congruent, or have the same measure), we can say that:
m<DIE = m<GIH = 40
m<GIE = m<HID = 140
m<CHI = m<AHB = 50
m<BHC = m<AHI = 130

Maria deposited $5,700 in an account that earns 8% simple interest. Maria made no withdrawals or deposits. What will be the total amount of money in her account after 6 years?
Answer:
FV= $8,436
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $5,700
Simple interest (i)= 8% = 0.08
Number of periods (n)= 6 years
To calculate the future value (FV), we need to use the following formula:
FV= PV*i*n + PV
FV= 5,700*0.08*6 + 5,700
FV= $8,436
4x-2=x+13
Solve for X
Show all steps
Answer:
x=5
Step-by-step explanation:
isolate the x on one side of the equal sign so move the 2 over by adding 2
4x=x+15 ( add 2 to both sides )
then move the x over
3x=15 ( subtract x from both sides )
then divide by 3
x=5
Answer: Hope it helps, have a nice day :)
x=5
Step-by-step explanation:
So you can only have x on one side, so first you move an x to the other side of the equal sign.
so, 4x-2=x+13, you can move either x, but I'm moving x instead of 4x
-x -x
Your new equation is 3x-2=13, because the x's cancel out
Then you add 2 on both sides 3x-2=13
+2 +2
___________
3x=15
then you divide by 3 on both sides
3x divided by three leaves x by itself, and 15 divided by three is 5.
3x=15
3 3
x=5
Rebecca is distributing fidget spinners as part of her campaign for school president. she has 500 fridge my spinners to distribute in packs of 25 per teacher. write a function modeling this situation. define all unknown variables
Answer:
Y= 20
Step-by-step explanation:
From the question, Rebecca has 500 fridge my spinners to distribute in packs of 25 per teacher, we can denote the number of this teacher with "Y" then for her to distribute those 500 fridge in packs of 25 per teacher, then we can say (25× Y)= 25Y ,since she has 500 fridge in total to distribute then we can write a write a function modeling this situation as
25Y=500
where Y is the number of teacher
Make Y subject of the formula we have
Y= 500/25
Y=20
Answer:
25x=500 or x=20
Step-by-step explanation:
__
Well Rebecca have 500 fidget spinners so you put that on one end and let x be the number of teachers if you have 25 fidget spinners per teacher you need to multiply 25 by the number of teachers or x to find out so the equation will look like this: 25x=500
If you want to simplify you divide by 25 into both sides which are 20
For each set of measurements, decide whether or not it is possible to draw a triangle with those measurements. If it is possible, draw the triangle. Side lengths 2 cm, 3 cm, and 4 cm Side lengths 2 cm, 3 cm, and 6 cm Angles 90 degrees, 45 degrees, and 45 degrees Angles 90 degrees , 60 degrees, and 60 degrees
Answer:
1. Triangle
2. Not a triangle
3. Triangle
4. Not a triangle
Step-by-step explanation:
Required
Check for valid triangles
Given 3 sides of a triangle: A triangle is valid If the sum of any two sides is greater than the third
1. Sides: 2cm, 3cm and 4cm
To check:
2cm + 3cm > 4cm --- True
2cm + 4cm > 3cm ---- True
3cm + 4cm > 2cm ----- True
The above conditions are true, hence the input values form a triangle.
2. Sides: 2cm, 3cm and 6cm
To check:
2cm + 3cm > 6cm --- False
2cm + 6cm > 3cm ---- True
3cm + 6cm > 2cm ----- True
One of the above conditions is false. Hence, the input values do not form a triangle.
Given the angles of a triangle, their sum must be equal to 180°
3. Angles: 90°, 45° and 45°
Sum = 90° + 45° + 45°
Sum = 180°
This is a valid triangle because the sum equals 180°
4. Angles: 90°, 60° and 60°
Sum = 90° + 60° + 60°
Sum = 210°
This is not a valid triangle because the sum does not equal to 180°
The above conditions are true, hence the input values form a triangle.

Find coordinates of the image of the point A(3,9) for a dilation with the scale factor of 2/3
Answer:
The coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)
Step-by-step explanation:
Given the point A with the vertices (3, 9) i.e. A(3,9)
As we know that If the scale factor is between 0 and 1, the image gets shrunk.
In order to dilation with a scale factor of 2/3, just multiply the x and y coordinates of the original point (3, 9) by 2/3.
i.e.
(x, y) → (2/3 x, 2/3 y)
so, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be:
A (x, y) → (2/3 x, 2/3 y) = A (2/3 (3), 2/3 (9)) = A'(2, 6)
Therefore, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)
Find X if m/angle UVY=84 degrees.
Answer:
x = 42º
Step-by-step explanation:
We know that m < UVY is equal to 84º (Given)
We know that < UVY = < SVW (Vertical Angles Theorem)
By substituting in the known values for the anges, we know that:
< UVY = < SVW
84º = 2x
Simplify the equation by dividing by 2 on both sides.
x = 42º
Hope this helps! Let me know if you have any questions!
Solution given:
<UVY=2x[vertically oppisite anglle]
