Answer:

9. y = 8

10. n = 21

11. 44 = v

12. c = 35

Step-by-step explanation:

9. 9y = 72

Divide each side by 9

9y/9 = 72/9

y = 8

10. 3n = 63

Divide each side by 3

3n/3 = 63/3

n = 21

11. 4 = v/11

Multiply each side by 11

4*11 = v/11*11

44 = v

12. c/7 = 5

Multiply each side by 7

c/7*7 = 5*7

c = 35

y=8
n=21

Question:
A running club keeps track of the number of hours each person has trained for a race and the length of time it takes the person to run the race. A scatter plot is graphed with the x-axis indicating the number of hours a runner has trained and the y-axis indicating the time, in minutes, it took to run the race. The equation y = 60 - 0.5x is used as the line of best fit of the data. What does the slope of the equation represent?

options:

a
Runners will decrease their race time by 2 minutes for every 1 hour they have trained.
b
Runners will increase their race time by 2 minutes for every 1 hour they have trained.
c
Runners will increase their race time by 1 minute for every 2 hours they have trained.
d
Runners will decrease their race time by 1 minute for every 2 hours they have traine

The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

What is scatter plot?

A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.

Here, we have,

We are given the scatter plot which shows the distance he has run and the time it took for each run.

We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?

One way to predict the time is by drawing a line that best fits the given data.

As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.

Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

A coffee grinder uses a current of 1.20 A and has a resistance of 100 ohms. Calculate the voltage explain

Answers

Answer:

Step-by-step explanation:

I = V / R

Current = (voltage) / (resistance)

Current = (500 V) / (250 ohms)

Current = (500/250) Amperes

Current = 2 Amperes

120V

VOLTAGE = CURRENT * RESISTANCE

1.20A * 100ohms

What is the area of the figure below?

Answers

answer: 88in^2
explanation: by separating the figure into easier pieces, simple triangles and rectangles, this problem becomes much easier.
by looking the overall length of the figure, we get 7, if you cut off the big rectangle in the middle from that seven, you end up with a diamond with a height of 10 and a length of 4. multiply those together to get the area of the points on either side.
10 x 4 = 40
now looking back at the rectangle, by adding up the heights, you get a height of 16. multiply this with the length of 3 and you get 48.
add the two and you get the total area.
40 + 48 = 88

Answer:

68 in

Step-by-step explanation:

Because the area of the squares is 3 x 3 = 9 and because there are two squares it is 18. The area of the central figure is 50 because i divided it into 4 triangles and 2 rectangles, each rectangle is 15 in and each triangle is 5 in so 15 x 2 = 30, 5 x 4 = 20 and 30 + 20 + 18 = 68

What is the Golden Rule for solving equations?

Answers

Answer:

Do unto one side of the equation, what you do to the other!

Step-by-step explanation:

An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the 'scale' (or equation) balanced so that both sides are ALWAYS equal.

Answer:

Keeping the equation balanced.

Step-by-step explanation:

You need to keep the equation balanced on both sides of the equal sign, like when you need to get rid of the number 4 on one side you have to do the same thing on the other side.

Ahmad’s goal is to exercise for a mean of 45 minutes per day for one week. For the first six days of the week, he exercised 35, 40, 37, 42, 45, and 50 minutes. What is the number of minutes Ahmad must exercise on the 7th day to meet his goal for the week?

Answers

Answer:

41.5

Step-by-step explanation:

To find the mean, your supposed to add all the numbers you have and divide by how many numbers there are. In this question your numbers are 35, 40,37,42,45, and 50.

If you add them all up you get 249. Your next step is to divide by how many numbers there are. Since there are 6, your equation will now be 249 divided by 6. Your answer is now 41.5

So on the 7th day Ahmad exercised for 41.5 minutes. If you need to round then maybe 41 minutes.

Answer:

41.5

Step-by-step explanation:

On the 7th day Ahmad exercised for 41.5 minutes and if you want to put it simply its 41 minutes.

The display at an aquarium has sea stars and eels in a ratio of 4:5. It also has 5/8 as many rockfish as sea stars. There are 40 more wolf eels than rockfish. How many Sea stars are there?

Answers

4.8 sea stars were there

64 sea stars in the aquarium.

What is Ratio?

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

Ratio of see stars to eels = S : E = 4:5

E = 5/4(S)

Ratio of rockfish to sea strars = R : S = 5:8

R = 5/8(S)

E = R + 40

5/4(S) = 5/8(S) + 40

Multiply by 8 both the sides

10S = 5S + 320

5S = 320

S = 320/5

S = 64

Hence, 64 sea stars in the aquarium
