Answer:

441 [tex]inches^{2}[/tex]

Step-by-step explanation:

If this is a rectangle, meaning the width and the legnth is different, there is no way in solving this.

However, if it is a square, meaning all the sides are the same,

we can know that every side is 21 inches long.

An area is the width times the length, which is both 21 in this case.

21 times 21 = 441.

441 inches squared.

Answer:

y=1/2x+8

Step-by-step explanation:

grab 2 points in this case (4,10) and (0,8)

use rise over run formula so it rises 2 and goes over 4

so 2/4 then simplify and you get 1/2

and the y intercept is 8 because thats when the slope touches the y line

so using the equation y=mx+b when m is slope and b is y interecpt

the answer should be y=1/2x+8

Answer:

y=2x+8

Step-by-step explanation:

8=b m=y_ý/x_x`=2

y=ax+b

y=2x+8

Answer:

12 cm^2

Step-by-step explanation:

The area of the rhombus is 12 cm².

Given that, a rhombus has a side length of 6 centimetres, and a height of 2 centimetres.

We need to find the area of the rhombus, in centimetres.

The formula for the area of the rhombus when base and height are known.

The rhombus is a parallelogram. We know that the area of a parallelogram is given by multiplying base and height sq units. The same is applied to the rhombus as well. Area of a rhombus = Base × Height sq units.

Now, the area of a rhombus= 6×2=12 cm²

Therefore, the area of the rhombus is 12 cm².

Answer:1. The coordinates of Jo’s house are (-4,-2).

Step-by-step explanation:

1. Since Jo’s house is reflected across both axes, we must reflect the coordinates two times. So we can reflect the coordinates of Kianna’s house across the x-axis first, which would give you the coordinates (4,-2). Then we reflect (4,-2) across the y axis, giving us the coordinates (-4,-2). So Jo’s house has the coordinates (-4,-2).

Answer:

  Y = 62°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

  W + X + Y = 180°

  (4n -9°) + (7n -16°) +(6n -16°) = 180°

  17n -41° = 180° . . . . . . . . . . simplify

  17n = 221° . . . . . . . . . . add 41°

  n = 13° . . . . . . . . . . divide by 17

Then the measure of Y is ...

  Y = 6n -16° = 6(13°) -16° = 78° -16°

  Y = 62°

_____

The other angles are W = 43°, X = 75°.

Angles of a triangle adds to 180° .

=> W + X + Y = 180°

=> (4n-9°) + (7n-16°) + (6n-16°) = 180°

=> 17n-41° = 180°

=> 17n = 180° + 41°

=> 17n = 221°

=> n = 221/17

=> n = 13°

=> 6n-16° = 6(13°) -16° = 62°

Y = 62°

Step-by-step explanation:

150 mph is equal to 2.5 miles per minutes divide miles by 2.5

Remember that a system of equations (two lines) only has solutions if the lines cross. In this case, the lines are parallel, which means that they will never cross. Therefore, there are no solutions.

========================================================

Explanation:

Check out the diagram below.

We have the following points

Let x be the length of segments DE and EC. Note how segment AB bisects segment DC. Whenever the radius is perpendicular to the chord like this, the radius will bisect the chord.

We're told that the chord length CD is the same as the radius AD, since CD = CE+ED = x+x = 2x, this means AD = 2x as well.

At this point, you probably can recognize we have a 30-60-90 triangle. One useful property of such triangles is that the hypotenuse is double the length of the short leg. The long leg is [tex]x\sqrt{3}[/tex] which is the length of segment EA. You can use the pythagorean theorem to confirm this.

----------------------------------

To summarize that last section, we formed triangle DAE and this triangle is a 30-60-90 triangle as shown in the diagram below.

Notice how the segments EA and FA span the entire width of the square. That width being [tex]EA+FA = x\sqrt{3}+x\sqrt{3} = 2x\sqrt{3} = EF[/tex]

The square has side lengths of [tex]2x\sqrt{3}[/tex] while the circle has radius 2x.

Use these two facts to find the area of each in terms of x.

[tex]A_1 = \text{area of square} = (\text{side})^2 = (2x\sqrt{3})^2 = 12x^2[/tex]

[tex]A_2 = \text{area of circle} = \pi*r^2 = \pi*(2x)^2 = 4\pi x^2[/tex]

-----------------------------------

The last step is to divide the two results. The x^2 terms cancel out.

We'll be left with...

[tex]\frac{A_1}{A_2} = \frac{12x^2}{4\pi x^2} = \frac{12}{4\pi} = \frac{3}{\pi} \approx 0.9549[/tex]

There are many ways to express this ratio. One way we could write it is to say 3:pi to indicate that if the area of the square is 3, then the circle has area of pi (approximately 3.14). No matter what the square's area is, the circle is always slightly larger in area.

Explanation:

There are 4 jacks (one of each suit) and 13 clubs. This gives 4+13 = 17 cards that are either jack or club. However, we double-counted the jack of clubs which means there are really 17-1 = 16 cards that are one or the other or both.

This is out of the 52 total mentioned. So we end up with the probability:

16/52 = (4*4)/(4*13) = 4/13

Graph C

Step-by-step explanation:

The life expectancies of residents of a country for which the average annual income is $80,000 for the three models are 12309.9352, 172.2436 and 4828.1393

The life expectancies of the models are given as:

[tex]y =69.9352 + 0.1530\times (income)[/tex] --- model 1

[tex]y =4.2436 + 0.0021\times (income)[/tex] --- model 2

[tex]y =4.1393 + 0.0603\times (income)[/tex] --- model 3

Given that the average annual income is $80,000;

We simply substitute 80000 for income in the equations of the three models.

So, we have:

Model 1

[tex]y =69.9352 + 0.1530\times (income)[/tex]

[tex]y =69.9352 + 0.1530\times 80000[/tex]

[tex]y =12309.9352[/tex]

Model 2

[tex]y =4.2436 + 0.0021\times (income)[/tex]

[tex]y =4.2436 + 0.0021\times 80000[/tex]

[tex]y =172.2436[/tex]

Model 3

[tex]y =4.1393 + 0.0603\times (income)[/tex]

[tex]y =4.1393 + 0.0603\times 80000[/tex]

[tex]y =4828.1393[/tex]

Hence, the life expectancies are 12309.9352, 172.2436 and 4828.1393

Answer:

  3.006, 3.06, 3.066, 3.6, 10

Step-by-step explanation:

Numbers written in a place-value system are compared left-to-right. If the digits with the same place-value multiplier being compared are the same, then the next digits to the right need to be compared.

The number 10 is the greatest. (None of the others have a digit in the 10s place.)

The number 3.6 is the next greatest. (6 in the tenths place is the largest digit there.)

The number 3.066 follows that, then 3.06.

3.006 is the least.

In order from least to greatest, the numbers are ...

  3.006, 3.06, 3.066, 3.6, 10
