Step-by-step explanation:
You know that he can run 5 miles in one hour, but want to know how long it takes him to run a mile. We will need to divide 1 hour (60) by 5 (total amount of miles he ran) to get 12.
i need to find the slopes from two points!show work.i don’t know how to do this
Answer:
4
Step-by-step explanation:
Ok.....Since I can't graph it, we can make a table
x y
3 9
1 1
From 9 to 1, you subtract 8 (this is for the y section)
From 3 to 1, you subtract 2 (this is for the x section)
Now all you have to do is divide the y with the x
y/x = 8/2 = 4
And 4 will be your slope for these two points.
Hope this helped!

Answer:
y = 42°
Step-by-step explanation:
The third vertex in the triangle with y is adjacent to a right angle, thus is right.
The sum of the 3 angles in a triangle = 180°, then
y = 180° - (90 + 48)° = 180° - 138° = 42°

3:4 3:1 2:3 1:3 9:7 6:7A pair of shoes that normally cost $30 have their price reduced by 25%. What is the sale price of the shoes?
Answer:$22.50
Step-by-step explanation: you save $7.50
Sale price of shoes = $22.5
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, we have to divide the given number by the whole number and multiply by 100.
Given,
Cost of shoes = $30
Discount on shoes = 25%
Discount = (25/100) × 30
Discount = 750/100
Discount = $7.5
Sale price = Cost - discount
Sale price = $30 - $7.5
Sale price = $22.5
Hence, $22.5 is the sale price of shoes.

Answer:
She will save [tex]\$24.44[/tex] by driving.
Step-by-step explanation:
Given: Jocelyn lives in Granite Falls. She wants to visit Megan in Spokane Valley. She can fly from Seattle to Spokane for [tex]\$96.20[/tex] round trip or she can drive a total of [tex]650[/tex] miles round trip. If her car gets [tex]25[/tex] miles per gallon, and gas costs [tex]\$2.76[/tex]/gallon.
To find: how much money will she save by driving?
Solution:
The total cost for flying Seattle to Spokane is [tex]\$96.20[/tex].
Now, in order to find how much money will she save by driving, we need to first find the total cost for driving a total of [tex]650[/tex] miles round trip.
So, total distance [tex]=650[/tex] miles.
Car covers [tex]25[/tex] miles per gallon.
So, to cover [tex]650[/tex] miles, [tex]\frac{650}{25} =26[/tex] gallons of gas is required.
Now, gas costs [tex]\$2.76[/tex]/gallon.
Therefore, total charge [tex]=26\times2.76=\$71.76[/tex].
So, total money saved[tex]=\$96.20-\$71.76=\$24.44[/tex]
Hence, she will save [tex]\$24.44[/tex] by driving.

Consider segment CD with coordinates C(7, -1) and D(-1, -6). Give the x coordinate of the midpoint of the segment?
===========================================================
Explanation:
The x coordinate of point C is x = 7
The x coordinate of point D is x = -1
Add up these x coordinates to get 7+(-1) = 6
Then cut that result in half: 6/2 = 3
The x coordinate of the midpoint is 3
The y coordinate of the midpoint is found in a similar fashion. You should find the midpoint is located at (3, -3.5) which is the same as saying (3, -7/2) since -7/2 = -3.5

Reflect this figure across the y-axis:
Answer:
The coordinates of the image triangle will be:
A'(-1, 1)B'(-1, 3)C'(-3, 3)Please also check the attached figure.
The green triangle represents the image triangle.
Step-by-step explanation:
We know that when we reflect a point across the y-axis, the y-coordinate remains the same but the x-coordinate reveres its sign.
Thus,
The rule of reflection of the point P(x, y) across the y-axis is:
P(x, y) → P'(-x, y)
In the attached figure, let the coordinates of the triangle are:
A(1, 1)B(1, 3)C(3, 3)Using the rule of reflection across the y-axis:
P(x, y) → P'(-x, y)
Thus, the coordinates of the image triangle will be:
A(1, 1) → A'(-1, 1)
B(1, 3) → B'(-1, 3)
C(3, 3) → C'(-3, 3)
Therefore, the coordinates of the image triangle will be:
A'(-1, 1)B'(-1, 3)C'(-3, 3)Please also check the attached figure.
The green triangle represents the image triangle.
The radius of the moon is approximately 1,350,000 m. What is the radius in centimeters? (1m=100 cm)
Answer:
[tex]1350000m = 135000000cm[/tex]
Step-by-step explanation:
Given
[tex]Radius = 1,350,000m[/tex]
Required
Convert to centimetres
In standard unit of conversion
[tex]1m = 100cm[/tex]
Multiply both sides by 1350000
[tex]1350000 * 1m = 1350000 * 100cm[/tex]
[tex]1350000m = 135000000cm[/tex]
Are the graph of 4x-3y=9 and y=3/4x+7 parallel, perpendicular, or neither? Explain.
Answer:
Neither
Step-by-step explanation:
In this question, we have to verify if the equations are parallel, perpendicular, or neither to each other.
Turn the first equation into slope-intercept form so we can get a better understanding:
4x - 3y = 9
Subtract 4x from both sides.
-3y = -4x + 9
Divide both sides by -3.
y = 4/3x - 3
Now lets compare both lines:
y = 4/3x - 3
y = 3/4x + 7
Since the slopes have to be the same in order for the lines to be parallel, we can see that the lines are NOT parallel.
We also know that in order for the lines to be perpendicular, one has to be positive and the other has to be negative. In this case, they both are positive. This means that the lines are NOT perpendicular.
This means that our answer would be neither.
The graph shows the motion of a car driving on a highway.
Enter a value to complete the statement.
Answer:
Car A's speed is 75 miles per hour
Step-by-step explanation:
As the distance-time graph represents the straight line. Thus, the slope of any line would remain constant along the line.
We also know that in a distance-time graph, the slope of the line would be equal to the speed of the object.
Taking two points from the graph
(0, 25)(1, 100)Determining the slope
Slope = [y₂-y₁] / [x₂-x₁]
= [100 - 25] / [1 - 0]
= 75 / 1
= 75 miles per hour
Therefore, Car A's speed is 75 miles per hour

Find the area of each figure. Round to the nearest hundredth where necessary.
The area of the first figure is 629.86 sq. meters and for the second figure, the combined area would be 430.18 629.86 sq. meters.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
For the first figure, we need to find the area of the semicircles and the area of the rectangle, then we get the combined area that gives the area of the figure.
The length of the rectangle is 28m. we can see that the diameter of the semicircle is equal to half of the length of the rectangle.
So. D = 14m and radius = 7m
The area of the 2 semicircles = [tex]\pi r^2[/tex]
= π x 7 x 7
= 49π sq. meter
The breadth of the rectangle = 24 - r
= 24 - 7
= 17m
The area of the rectangle = length × Width
= 28 x 17
= 476 sq. meter
The combined area = 629.86 sq. meter
B. The area of the 2 semicircles = [tex]\pi R^2[/tex] + [tex]\pi r^2[/tex]
= π ( 11 x 11 + 4 x 4)
= 3.14 x (121 + 16)
= 430.18 sq. meter
