THE SUBJECT IS SCIENCE.

Answers

When warm moist air meets colder drier air, the warm air rises, the water vapor condenses in the air, and forms a cloud. As the water vapor condenses it releases heat, which is a form of energy.

Answer:

Kinetic energy is present.

Step-by-step explanation:

It's present by the moving winds in the storm, and by the winds moving things such as trees, branches, or plants.

which of these would be a helpful first step in solving the equation? check all that apply. 7x - 9 = 2x + 21

Answers

Answer: E. Subtract 2x

Step-by-step explanation:

Subtracting 2x would remove a bit from both equations, giving us 5x - 9 = 12. This would make it easier now that we only have one number on a side.

Hope this helps!

Subtract 2x because you need to get the x value on one side and number on the other

You are standing at the top of the mountain 1,500 feet above sea level and your brother is a scuba diving in the ocean 10 feet below sea level. Write an expression using absolute values to determine the difference between the 2 positions.

Answers

Answer:

To find the absolute value remove abt negative sign in front of a number and to think of all numbers as a positive

Step-by-step explanation:

The expression using absolute values to determine the difference between the two positions is → d = x + |y| , where : x = +1500 and y = -10.

What are expressions?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators

Given is that you are standing at the top of the mountain 1,500 feet above sea level and your brother is a scuba diving in the ocean 10 feet below sea level.

For 1500 feet above the sea level, we can write -

{x} = + 1500 ft

For 10 feet below the sea level, we can write -

{y} = - 10

Assume the difference between the two positions is equal to {d}. So, we can write -

d = x + |y|

d = 1500 + |- 10|

d = 1500 + 10

d = 1510 ft

Therefore, the expression using absolute values to determine the difference between the two positions is → d = x + |y| , where : x = +1500 and y = -10.

Answers

Answer:

1.) Mean= 136

Median=133

2.) Mean=136

Median=133

Answer: Landers

Mean = 136

Median = 133

Skakalski

Mean = 130

Median = 133

Step-by-step explanation: to find the mean add all the numbers then divide it by how many numbers there are.

To find the median write all the numbers from smallest to largest then cancel the number at the end until you reach the “middle” number.

a 4000 pound car driving at 40 miles/hour has how many times the kinetic energy of another 4000 pound car driving at 10 miles/hour.

Answers

Answer = 400 I think
Explain = do 4,000 five by 40 then get a answer of 100 and then do 4,000 divid by 10 and get 400 do you see the similarities of both of these question they are the same question but just written in different ways just by adding a zero.

The comparison of the kinetic energy of the given bodies is required.

The first car has 16 times more the kinetic energy of the second car.

Kinetic energy

m = Mass of car = 4000 pound

[tex]v_1[/tex] = Initial velocity of car = 40 miles/hour

[tex]v_2[/tex] = Final velocity of car = 10 miles/hour

The mass of the car is constant so we have the relation

[tex]K\propto v^2[/tex]

Thus,

[tex]\dfrac{K_1}{K_2}=\dfrac{v_1^2}{v_2^2}\\\Rightarrow K_1=K_2\dfrac{40^2}{10^2}\\\Rightarrow K_1=16K_2[/tex]

What is 2.75 years in months?

Answers

Answer:

About 33.

Step-by-step explanation:

In 1 year, there are 12 months. We have 2 years here, so we do 12x2, which is 24. We also have .75.

Well, .5 (half) of the year would be 6. A quarter of the year would be 3.

.75 is equal to 3 quarters, so we do 3x3, getting 9.  

24+9=33

the cost of 2 quesadillas and 3 burritos at a local mexican restaurant is $32. The cost of 4 quesadillas and 2 burritos at the same restaurant is $34. what is the cost of one quesadilla and 1 burrito?

Answers

It’s 7 each quesdilla and 6 burrito

Answer:

1 quesadillas is $4.75 and 1 Burrito is $7.50

Step-by-step explanation:

This question is a form of simultaneous equation

1. Quesadillas represents x and Burrito represents y

2. Form an equation base on the problem, hence as written below.

2x+3y=32

4x+2y=34

3. Use the elimination method by minusing the first equation from the second equation to give y=2x-2

4. Then you substitute the y=2x-2 into one of the equations above to find the x value. Eg y value substituted which is 2x+3(2x-2)=32. Therefore x=4.75

5. To find y substitute x value into either of the equation to find the y value.

Eg: 2(4.75)+3y=32. Therefore, make Y the subject to find Y value. Y= 7.50

Answer: The y-intercept (b) is 10.

Step-by-step explanation:

Use the slope and the point to help you. Plot the point (-3,4) on graphing paper or use geometry software. I use geometry software, it's easier.

You'll need to understand that the slope 2 can also be written as 2/1 (rise/run). Go up 2 units and go to the right 1 unit, then plot a point. Keep going until one of the points lies on the y-axis. The y-coordinate of that point is the y-intercept. So, the y-intercept (aka "b") is 10.

Answer:

(12, 0) & (3, -1) & (0, -3/4)

Step-by-step explanation:

x - 9y = 12

Plug in the point and solve:

12 - 9(0) = 12

12 = 12

3 - 9(-1) = 12

3 + 9 = 12

12 = 12

0 - 9(-3/4) = 12

12 = 12

Answer:

(12,0), (3,-1), and (0,-4/3)

Step-by-step explanation:

Just replace x and y in the equation with the coordinates.

12-9(0)=12

solve to see if it is true. First solve 9(0) which is 0. Which leaves us with        12-0=12 and this is true because it fits.

Now with (3,-1)

3-9(-1)=12

Solve to see if true. First solve 9(-1) which is -9. this leaves us with 3-(-9)=12

3-(-9) does equal 12 so this one is true as well.

Same thing with (0,-4/3)
