Summer and Autumn are friends who live 25 miles apart and they are training for a long race. On wednesday after school, they ran toward each other’s houses to meet up. They left their houses at 4pm and met at 6 pm. Summer ran an average rate of 8 ½ miles per hour faster than autumn. What is the average speed of each?
Answer:
Autumn's average speed is 1.3158 mph
Summer's average speed is 11.1843 mph
Step-by-step explanation:
We are told that they live 25 miles from each other.
They left their houses at 4pm and met at 6 pm. This means they met 2 hours later.
Now, summer ran 8.5 mph faster than autumn.
This means if autumn's speed is "x", then summer ran 8.5x mph
Thus, total distance covered by summer is; d_summer = 8.5x * 2 = 17x
Total distance by autumn is; x * 2 = 2x
Since their houses are 25 miles apart.
Thus;
17x + 2x = 25
19x = 25
x = 25/19
x = 1.3158 mph
Thus, autumn's speed is 1.3158 mph
Summer's speed is 1.3158 × 8.5 = 11.1843 mph

Write the slope of a line that is parallel to the following line:
y =1/3x *+1
Answer: -3
y = -3x+1 has a slope of -3. Since parallel lines have equal slopes, the new line will also have a slope of -3
Step-by-step explanation:
Answer:
Slope = 1/3
Step-by-step explanation:
[tex]y =1/3x +1\\\\y=\frac{1}{3} x+1[/tex]
The equation is arranged in slope-intercept form :
[tex]y=mx+b[/tex]
Where m = slope

What are coordinates?A pair of numbers called coordinates are used to locate a point or a form in a two-dimensional plane. The x-coordinate and the y-coordinate are two numbers that define a point's location on a 2D plane.
Given, Russell conducted an experiment where he collected snow in a container, measured it, and then measured the amount of water in the container after the snow had melted.
D is wrong and C is wrong Because they're asking us what does the point (0,0) represents.
Obvious X is the independent variable So 0 inches of snow in no water So we should choose Option A.
Therefore, we can say that the graph represents that The collection of 0 inches of snow results in no water.

If m\displaystyle \angle∠F = (6x + 7) and m\displaystyle \angle∠H = (9x - 14), then solve for m\displaystyle \angle∠F if the two angles are Alternate Interior Angles.
Answer:
m<F = [tex]49^{o}[/tex]
Step-by-step explanation:
Alternate interior angles have equal values. So that;
m<F = m<H
Given that: m<F = (6x + 7) and m<H = (9x - 14).
Then,
(6x + 7) = (9x - 14)
6x + 7 = 9x - 14
collecting like terms, we have
6x - 9x = -7 - 14
-3x = -21
3x = 21
Divide both sides by 3, to have;
x = [tex]\frac{21}{3}[/tex]
= 7
therefore,
m<F = (6x + 7)
= 6 x 7 + 7
= 42 + 7
= [tex]49^{o}[/tex]
m<H = (9x - 14)
= 9 x 7 - 14
= 63 - 14
= [tex]49^{o}[/tex]

Morgan won 7 blue ribbons and 4 red ribbons at her horse shows. What is the ratio of red ribbons to blue ribbons she won?
a. 4/11
b. 4/7
c. 7/11
d. 7/4
Answer:
b 4 red ribbons/7 blue ribbons
The required ratio of red ribbons to blue ribbons is 4/7 which is the correct answer would be an option (A).
What is the Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that Morgan won 7 blue ribbons and 4 red ribbons at her horse shows.
We have to determine the ratio of red ribbons to blue ribbons she won
The ratio of red ribbons to blue ribbons is equal to the number of blue ribbons divided by the number of red ribbons.
The ratio of red ribbons to blue ribbons = the number of red ribbons /the number of blue ribbons.
The ratio of red ribbons to blue ribbons = 4 / 7
Thus, the required ratio of red ribbons to blue ribbons is 4/7.

The function $y=2x+8$y=2x+8 represents the cost $y$y (in dollars) of a large pizza with $x$x toppings, where $x$x is equal to 0, 1, 2, or 3. Identify the independent and dependent variables, the domain, and the range.
Step-by-step explanation:
The function that represents the cost of pizza with toppings as follows :
y = 2x+8 ...(1)
Where x = 0,1,2 and 3
Here, y depends on x it means y depends on x. y is a dependent variable and x is independent variable.
Domain is the set of input values and range is the output values.
Domain = 0,1,2 and 3
Now, put x = 0 in function (1)
y = 2(0)+8 = 8
Put x = 1 in function (1)
y = 2(1)+8 = 10
Put x = 2 in function (1)
y = 2(2)+8 = 12
Put x = 3 in function (1)
y = 2(3)+8 = 14
So, the range of the function is 8,10,12,14.

Answer: 30 kids.
Step-by-step explanation:
Since Mrs. Cunningham's ratio from boys to girls is 2:3 ( with girls being 3) you just need to multiply 6 to 3 to get 18. But you also need to multiply 6 and 2 then add both numbers together, which gets you to 12.
Answer:
30
Step-by-step explanation:
because if ratio 3 is girls and there are 18 of them if you divide that by 3 you get 6 than multiply 6 time the ratio of boys 2 to get 12 then add 18+12

On average it takes 20 gallons of gas for a school but to travel 298 miles create an equation that describes the distance traveled, d, in relation to the number of gallons used, g.
Answer:
d = 14.9(g)
Step-by-step explanation:
Given:
Amount of gas used = 20 gallons
Distance traveled = 298 miles
Find:
Equation
Computation:
Distance travel in 1 gallon = 288 / 20
Distance travel in 1 gallon = 14.9 miles
Distance traveled = 14.9(Amount of gas used)
d = 14.9(g)
