The Graph Models The Linear Relationship Between The Temperature Of Earth's Atmosphere And The Altitude

Answers

Answer 1

Answer:

A. -6.5°C/km

Step-by-step explanation:

It's easier to find slope if we can locate two points.

Looking at the graph, it looks like it passes through the points (4, -10) and (7,-30).

To find the slope, we divide the difference of the y-coordinates by the difference of the x-coordinates. Here, the difference in the y-coordinates is:

-10 - (-30) = -10 + 30 = 20

The difference in the x-coordinates is:

4 - 7 = -3

So, the slope is:

20/(-3) = -20/3 ≈ -6.67

This is the closest to the first answer choice, -6.5°C/km, so that is the answer.

d. (15 + 9) ÷ 3 − 2

Answers

Answer:

The answer is A. 15+(9÷3)-2

Step-by-step explanation:

Well first we need to solve the current equation

15+9÷3-2

We should use PEMDAS. Since we do not need to do any parentheses, exponents, or multiplying. So we need to move onto division. 9÷3 would equal 3 so not the original equation looks like...

15+3-2

Now we will move on to adding and add 15 and 3 which equals 18. This leaves us with our last step....

18-2

We need to subtract 2 from 18 which will leave us at 16. Now that we have solved the original equation we can solve the others to find the answer using PEMDAS

A. 15+(9÷3)-2

15+3-2

One brother says of his younger brother: “Two years ago, I was three times as old as my brother was. In three years’ time, I will be twice as old as my brother.” How old are they each now?

Good Luck!!

Answers

Answer:

17

Step-by-step explanation:

Let us suppose two years ago my brother's age was x years

Then, my age was 3x

Three years from now, my brother's age will be (x +2+3) = (x+5) years

And my age will be (3x+2+3) = (3x+5) years

But it is given that i will be twice as old as my brother.

So, 2(x+5)= (3x+5)

or, x= 5 years

So my brother's present age is 5+2= 7 years

And my age is 5*3+2= 17 years

Pretty sure that the answer is 17

D

Step-by-step explanation:

If the minimum amount you can spend is $37 then that is 6 rides.

37-25=12$
With 12$ you can go on only 6 rides

53$-25&=28
28/2 equals 14 rides which is the maximum

Answer:

x = 34

Step-by-step explanation:

90° + 42° = 132°

180° - 132° = 48°

m∠DFE = 48°

2x + 48 + 64 = 180

2x + 112 = 180

2x = 68

x = 34

Answer:

FIrst, lets set up some rules to keep in mind:

The interior angles of any triangle will add up to 180°

Therefore, m<FED + m<FDE + m<DEF or in other words 64 + 2x+ m<DFE=180

Next, lets note that there are supplementary angles in this problem which are a set of angles that add to 180°. For example, m<HFC + m<EFH + m<DFE = 180.

With those in mind lets solve:

If we find the m<DFE then we can find the value of x since the interior angles of any triangle add to 180.

to find f we can use supplementary angles.

42°+90°+m<DFE=180

132+m<DFE=180

m<DFE=48°

Therefore,

64+48+2x=180

112+2x=180

2x=68

x=34

To check our answer we can plug in 34 for x and the 3 interior angles of that triangle should add to 180

2(34)+64+48=180?

68+64+48=180?

180=180

x=34 is valid
