Answer:

  2.4

Step-by-step explanation:

We can see that this is a 3-4-5 right triangle, so side AB is 5 units long.

The area of the triangle is ...

  A = 1/2bh = 1/2(3 units)(4 units) = 6 units

This is true also when side AB is the base and CD is the height.

 A = 1/2(AB)(CD)

  6 = 1/2(5 units)(CD) . . . . . substitute given information

  6/2.5 = CD = 2.4 . . . . . . . divide by the coefficient of CD

The length of side CD is 2.4 units.

In the attached, the height to vertex C is given on the bottom line.

Answer:

answer: its c 108

Step-by-step explanation:

for the rectangles I just did base x height for all of them and got 24, 32, and 40 then I do the two triangles for those its just base x height ÷ 2 So 4 x 3 = 12 then I divide that by 2 and get 6 but since there's two of those triangles I multiply by 2 and end up with twelve again then I add all of these numbers up so...

24 + 32 + 40 + 12 = 108 Hope this makes sense to you!

Answer:

B is the correct answer..

Answer:

The first one

Step-by-step explanation:

when you are doing work with decimals the less numbers behind the decimal the bigger the decimal the more numbers the smaller the decimal based on that, 3550 is the biggest so that would go first. 13 is the next biggest and 0.3 is the same as 0.30 and there are less numbers after the decimal so that is the next biggest. 0.35 would go next because there are more numbers behind the decimal which makes it the smallest. I hope this helps :P

Answer:

56π units²

Step-by-step explanation:

area of entire circle = πr² = π8² = 64π

360° - 45° = 315°

(315/360)(64π) = 56π units²

Answer:56 square Units

Step-by-step explanation:

Answer:

2 1/6

Step-by-step explanation:

Given equation of the Circle is ,

[tex]\sf\implies x^2 + y^2 = 25 [/tex]

And we need to tell that whether the point (-4,2) lies inside or outside the circle. On converting the equation into Standard form and determinimg the centre of the circle as ,

[tex]\sf\implies (x-0)^2 +( y-0)^2 = 5 ^2[/tex]

Here we can say that ,

• Radius = 5 units

• Centre = (0,0)

Finding distance between the two points :-

[tex]\sf\implies Distance = \sqrt{ (0+4)^2+(2-0)^2} \\\\\sf\implies Distance = \sqrt{ 16 + 4 } \\\\\sf\implies Distance =\sqrt{20}\\\\\sf\implies\red{ Distance = 4.47 }[/tex]

Hence the point lies within the circle .

Answer:

inside the circle

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

x² + y² = 25 ← is in this form

with r = [tex]\sqrt{25[/tex] = 5

Calculate the distance d from the centre to the point (- 4, 2 ) using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (- 4, 2)

d= [tex]\sqrt{(-4-0)^2+(2-0)^2}[/tex]

   = [tex]\sqrt{(-4)^2+2^2}[/tex]

   = [tex]\sqrt{16+4}[/tex]

    = [tex]\sqrt{20}[/tex]

    ≈ 4.5 ( to 1 dec. place )

Since 4.5 is less than the radius of 5

Then (- 4, 2 ) lies inside the circle

All you need to do is find the frequency of the Science Test Scores. For Example, there are 6 students that made a 90%. So, you put 6 dots on the graph where it says 90. For the rest of the numbers, you do the same thing. 3 students made a 50, 2 students made a 60, 7 students made a 70, 5 students made an 80, and like I said 6 students made a 90. Add 0 dots to 40% and 100%, as you can see no students made a 40 or a 100 :(

Answer:

9 shirts

Step-by-step explanation:

20% of the shirts were blue

20% of 30 is 6

6 shirts were blue

1/2 of the shirts were black

1/2 = 50%

50% of 30 is 15

15 shirts are black

15 + 6 = 21

30 - 21 = 9

(or you could add the percentages to get 70%, and get 30%. 30% of 30 is 9.)

Answer:

The volume of prism B is 490 cubic inches.

Step-by-step explanation:

To determine what is the volume of prism B if the volume of Prism A is 367.5 inches, and the scale factor is 3: 4, the following calculation must be performed:

3 = 367.5

4 = X

4 x 367.5 / 3 = X

1,470 / 3 = X

490 = X

Therefore, the volume of prism B is 490 cubic inches.

Answer:

13.4%

Explanation:

So the change in population is 9,000. The percentage of population loss is just the change in population divided by the original population.

x=9,00067,000=0.134

Turn 0.134 into a percent so that we get 13.4%. So the percent of population loss is 13.4%.

Answer:

Sum of Interior Angles = 900°

One Interior Angle = 128.57°

Step-by-step explanation:

We know that the figure is a Heptagon (a 7 sided polygon), therefore;

→ As by the formula of (n - 2) * 180° we can find the sum of the interior angles;

=> (n - 2) * 180 = Sum of Interior Angles

=> (7 - 2) * 180 = Sum of Interior Angles

=> 5 * 180 = Sum of Interior Angles

=> 900° = Sum of Interior Angles

Now that we know the sum of interior angles,

→ We can find 1 interior angle by dividing the sum by the number of sides in the polygon.

=> Sum of Interior Angles / n = One Interior Angle

=> 900 / 7 = One Interior Angle

=> 128.57° = One Interior Angle
