Answer:

5/4

Step-by-step explanation:

First plot any2 points. Next count how many units it is High and Left/Right to get to the second point!

(Added your graph for further explaination :)

First, determine 2 points on the graph. I'd recommend to choose 2 points that are next to each other to make it easier.

Second, see how many units higher the first point you chose (on the left) is than the second point you chose (on the right). Say it is 3 units, then you mark a points 3 units above the first point.

Third, see how many units to the right the second point is to the first. If it is 5 units, you would go to the point you marked on the previous step, and move 5 units to the right. If you did it correctly, it should end up on the second point you chose. The segment you drew should kind of look like a box.

Now, make a proportion. Put how many units you rose in the second step at the top, and how many you ran at the bottom. Treat this like a fraction and simplify. You have your slope!

Going higher and to the right is the formula rise/run. How many units do you rise, how many do you go right? I recommend doing this when finding slope on a graph

Hope I helped!!!!!!!!!!!!! :)

Solve the percent change . state if increase or decrease.

Dmitry [639]

Answer:

1.) 18 is decreasing by 83%

2.) 16 is decreasing by 12.5%

Step-by-step explanation:

Part ÷ Whole = Percent (decimal form)

1.) First, you subtract the smaller number from the larger number: 18 - 3 = 15. Then you find the percent of the part: 15 ÷ 18 = 0.833333333333. This can be rounded to 0.83. Multiply 0.83 by 100 to get the percentage: 0.83 • 100 = 83%. To check your answer, multiply 0.83 by 18. It checks out. 18 is being decreased by 83%.

2.) Subtract 14 from 16 to get 2. Then divide 2 by 16: 2 ÷ 16 = 0.125. Multiply that by 100: 0.125 • 100 = 12.5%. To check this, we multiply 0.125 • 16 = 2. It works. So, 16 is being decreased by 2%.

Hope this helps,

Two urns contain white balls and yellow balls. The first urn contains 3 white balls and 6 yellow balls and the second urn contai

astra-53 [7]

A = event that the ball drawn from urn #1 is white
B = event that the ball drawn from urn #2 is white

P(A) = probability of event A
P(A) = (number of white in urn #1)/(number total in urn #1)
P(A) = 3/(3+6)
P(A) = 3/9
P(A) = 1/3

P(B) = probability of event B
P(B) = (number of white in urn #2)/(number total in urn #2)
P(B) = 3/(3+8)
P(B) = 3/11

Because A and B are independent events, we can multiply the probabilities
P(A and B) = P(A)*P(B)
P(A and B) = (1/3)*(3/11)
P(A and B) = (1*3)/(3*11)
P(A and B) = 1/11

Answer: Choice A) 1/11

Theo has $5 more than Denise and Denise has $11 more than Rudy. Together they have $45. How much money does Denise have?

Blizzard [7]

Let
x------> amount of money Theo has
y------> amount of money Denise has
z------> amount of money Rudy has

we know that
x+y+z=$45-----> equation 1
x=5+y-----> equation 2
y=11+z----> equation 3

substitute equation 2 in equation 1
[5+y]+y+z=45-------> 2y+z=40-----> equation 4

y=11+z----> equation 3
2y+z=40-----> equation 4

resolves the equations system
using a graph tool
see the attached figure

the solution is
y=17
z=6
x=5+y----> x=5+17----> x=22

the answer is
Denise has $17

How do I find the area of the circular racetrack?

BabaBlast [244]

Answer:

8483 ft²

Step-by-step explanation:

Subtract the area of the smaller circle from the area of the greater circle

Greater Circle area:

πr² = π × 140²

= 61583.2 ft²

Smaller Circle area:

= π × 130²

= 53099.8 ft²

Area of track:

61583.2 - 53099.8 = 8483.4ft²

= 8483ft² (to the nearest ft²)
