Answer: B. Mantle

Step-by-step explanation:

I just couldn't pass up answering this question. I think the earth is very interesting.

The Earth's mantle is a thick layer of hot, flowing rock that lies beneath the crust. Convection currents within the mantle are responsible for the movement of the Earth's tectonic plates, which make up the continents and the ocean floor. As the mantle convects, it drags the plates along with it, causing them to move and interact with each other at their boundaries. This movement is responsible for many geological phenomena, including earthquakes, volcanoes, and the formation of mountain ranges.

Answer:

d =5400 ft

Step-by-step explanation:

d = rt

where d is distance r is rate and t is time

d = 60 ft/ min * 90 min

d =5400 ft

Answer:

5400ft

Step-by-step explanation:

If you are travelling 60ft/min or 60 feet in one minute, you can multiply by 90 minutes to find the number of feet you will travel in that time.

60ft/min * 90min = 5400ft

If they want an approximate mileage, it is just above 1 mile. (1.022727miles)

Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.

So basically the units are counting up by 5.

The x axis is age in years and y axis is the number of US states named in 60 seconds.

Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.

(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

Step-by-step explanation:

THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!

The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.

The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Answer:

1a)81 b)54 c)27 d)0

Step-by-step explanation:

for number one the answer is 27 x what is given

Answer:

Step-by-step explanation:

You want the number of small cubes painted on 3, 2, 1, and 0 faces if the outside surface of a cube comprised of 27 small cubes is painted. You also want the height of 200 L of water in a tank of 50 cm radius with a 20 cm radius hole in the middle.

The number of cubes painted on 3 faces is the number of corner cubes: 8.

The number of cubes painted on 2 faces is the number of center-edge cubes, 12.

The number of cubes painted on one face is the number of center-face cubes, 6.

The number of cubes with no painted faces is the number of cubes buried inside, 1.

The painting is ...

The total is 27, as it should be.

The area of the base of the part holding water is ...

  π(50² -20²) = π(2500 -400) = 2100π cm²

The height of 200 L of water will be h, where the volume of the figure is ...

  V = Bh

  V = (2100π cm²)h = 200·1000 cm³

  h = 200/(2.1π) cm ≈ 30.3 cm

The height of the water in the tank will be about 30.3 cm.

__

Additional comment

When working with volumes in liters, it is often convenient to work with dimensions in decimeters (dm), where 1 dm = 10 cm. This is because 1 dm³ = 1 L.

Here, the area is π(5² -2²) = 21π dm², so the height is (200 dm³)/(21π dm²) ≈ 3.03 dm = 30.3 cm.

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Hope you understood the answer and I hope it helps you :)

Step-by-step explanation:

0.5% of w is 12 is what they are asking

0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is

\(12 = 0.005 \times w\)

Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite

\(w = \frac{12}{0.005} = 2400\)

  Michael is wrong

Step-by-step explanation:

You want to know which student has misunderstood their grade computation, given the mean and median scores shown.

The mean of the test grades is their sum, divided by their number. The values shown for the mean grades are correct.

"Average" is another name for "mean." Thus the students' grade average will be the value of their mean grade, not their median grade.

Answer: 5400

Step-by-step explanation: image attached

Answer:

5400

Step-by-step explanation:

we need to calculate the area of big box (prism).

volume = 4 1/2 X 5 X 3 3/4

= 84.375 in³.

volume of small cube = 1/4 X 1/4 X 1/4

= 0.015625 in³.

now we need to find how many of the small ones go into the big one.

84.375/0.015625

= 5400.

Answer:

1. 158 degrees

2. 36 degrees

3. 150 degrees

4. 80 degrees

Step-by-step explanation:

1. angle x and the given angle are supplementary angles because they add up to form a straight line. This means the two angle measures add up to 180 degrees, so angle x + 22 = 180, and angle x = 180 - 22 = 158 degrees

2. angle x and the given angle are supplementary angles so angle x = 180 - 144 = 36 degrees

3. angle x and the given angle are supplementary angles, so angle x = 180 - 30 = 150 degrees.

4. angle a is just the sum of the two angles: a = 30 + 50 = 80 degrees

Answer and Step-by-step explanation:

For the first question (#4) we can simply add the two angles together:

50+30=80

For the second picture (#3) we can see that the angles are adjacent, and therefore add up to 180 degrees. Since we know that, we can subtract 30 from 180 to find x:

180-30=150

We can use the same rule for the third picture (#1), and subtract 22 from 180:

180-22=158

And one last time, we can subtract 144 from 180 for the fourth picture (#2) since they are also adjacent:

180-144=36

or, (2m/2)>(14/2)             [also dividing both sides by a non-negative number     doesn't change the inequality sign]

or, m>7.

Hence, m>7 is the correct answer to the given question.

Answer:

x=9

Step-by-step explanation:

x + x - 4 + x - 4 = 19

3x - 8 = 19

3x = 19 + 8

3x = 27

x = 9

Answer: x=9

Step-by-step explanation:

There are three sides 2 that are x-4 and 1 that is x. The equation would be

x+2(x-4)= 19 so you would simplify to get

X+2x-8=19 then 3x=27 then divide by three to get x=9

Answer: 780 Sheets of paper.

Step-by-step explanation:60/5=12, 12x65=780

{11, 14, 22}

     Triangle Inequality Theorem states that two sides of a triangle must be greater than the third side.

     Using this method, the answer is {11, 14, 22} because 11+14>22, 11+22>14, and 14+22>11

x = 67°

Same-side interior angles are supplementary.

     x° + 113° = 180°

     x° = 180° - 113°

     x = 67°

r = 2°

     The little box represents 90 degrees, meaning that these angles are complementary.

     9r + 2° + 70° = 90°

     9r + 72° = 90°

     9r = 18°

     r = 2°

Thats really hard but I think its C

Step-by-step explanation:

The product of these dimensions rounded to the nearest whole number of centimeters option is D) 13 cm x 9 cm.

That parallelogram in which adjacent sides are perpendicular to each other is called a rectangle.

A rectangle is always a parallelogram and a quadrilateral but the reverse statement may or may not be true.

The size of a rectangular photo frame is 12 11/16 cm by 8 3/4 cm.

So, the product of these dimensions

12 11/16 cm x 8 3/4

12.68 x 8.75

So, the rounded to the nearest whole number of centimeters

13cm x 9 cm

Thus, the correct option is D) 13 cm x 9 cm
