I don't understand this. Please explain the answer. I have a final exam coming up.

Answer: 3/5

Step-by-step explanation: y2-y1/x-x1 is the formula for slope so you plug in. 2-(-1)=3 and 3-(-2)=5 and since you can't simplify anymore your answer is 3/5.

Hope this helps and I did not use the picture but here is what I know

Answer: Mercury's average distance from the sun is 5.791 x10e9 km. about how many times farther from the sun is Neptune than mercury? On average, Mercury is about 57,000,000 km from the sun , whereas Neptune is about 4.5*10^9 km from the sun.

Answer:

76%

Step-by-step explanation:

For the definition of mean we can write this equation

(75 + 86 + 83 + x)/4 = 80

(244 + x)/4 = 80

244 + x = 320

x =76 %

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

D, 70 to 72 seconds

Step-by-step explanation:

The function increasing in the interval,

70 to 72 seconds.

The function decreasing in the interval,

64 to 66 seconds.

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

Given:

Kyle went to the state fair and rode the Ferris wheel.

The graph represents the last 40 seconds of Kyle's Ferris wheel ride.

From the graph:

The function increasing in the interval,

40 to 44 seconds, 50 to 52 seconds, 56 to 60 seconds and 70 to 72 seconds.

The function decreasing in the interval,

44 to 48 seconds, 52 to 56 seconds, 64 to 66 seconds.

Therefore, the intervals are given above.

Answer:

36.8/2.8 = 16

Expression 1 = 368/28

Expression 2 = 3.68/.28

Step-by-step explanation:

If you move the decimal the same on both numbers of a division problem the answer stays the same.

Answer:

1. 32÷2, 64÷4

2. 16

Step-by-step explanation:

Expression 1:

32÷2=16, and 64÷4=16.

Expression 2:

Change the divisor 2.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

368 ÷ 23 = 16

and therefore:

36.8 ÷ 2.3 = 16

Both calculated to 0 decimal places.

Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

8: 73.2

10: 738

Step-by-step explanation:

Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]

where a and b = base lengths and h = height

For #8

These are the given dimensions

Base 1 = 4.5

Base 2 = 7.5

Height = 12.2

All we have to do is plug in the values into the formula

So....

[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]

Hence the answer is 73.2cm²

For #10

Once again all we have to do is plug in the values into the formula

[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]

Hence the answer is 738

Answer:

the answer is A

Step-by-step explanation:

[tex]x + 10 = 2x - 4 \\ 10 + 4 = 2x - x \\ x = 10 + 4 \\ x = 14[/tex]

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.  

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.
