Answer

Step-by-step explanation:

Answer:

B. 56π

Step-by-step explanation:

Circumfrance = 2πr OR πd(r*2)

C = 2π(28) -> C = 56π

OR

C = π(28*2) -> C = 56π

Answer:

B (56π)

Step-by-step explanation:

Circumference = 2πr or πd

C = 2π(28) (after completing this step:) C = 56π

Thus, C = 56π

Answer:

10π

Step-by-step explanation:

Since ME is the diameter of the circle,

angle MTE = 90° (∠ in semicircle)

By pyth. theorem we can obtain,

ME = √8² + 6²

ME = 10

The diameter of the circle is 10

The circumference of circle D is 10π

Answer:

<MTE =90°

the inscribed angle from the diameter is 90°

in triangle MTE

MT=8 unit

TE=6unit

by using Pythagoras law

D=ME=√(8²+6²)=10 unit

radius =D/2=10/2=5unit

circumference of circle D=2πr=2π×5=10π or31.4unit

Answer:

580 cm

Step-by-step explanation:

To find the surface area you just need to find the area of every side of the box and add them together.

SO- the equation for this would be

SA (Surface Area) = 2(20 x 10) + 2(20 x 3) + 2(10 x 3)

SA = 2(200) + 2(60) + 2(30)

SA = 400 + 120 + 60

SA = 520 + 60

SA = 580

Step-by-step explanation:

Answer:

Step-by-step explanation:

so this question is about perpendicular lines.    keep in mind that a perpendicular line has a reciprocal slope of opposite sign, from the line it's perpendicular to .  :)  okay so what is that line the robot is on, let's first  

find the slope  , m

m = (y2 - y1)  / ( x2 - x1)  

P1 = (8,6)  in the form ( x1,y1)

P2= (-10,-5) in the form (x2,y2)

then

m = (-5-6) / (-10-8)

m = -11 / -18

m = 11/ 18

and then lets use the point-slope formula with the slope we just found and one of the given points, let's pick  P1

y-6 = 11/18(x-8)

y = 11/18x - 88/18 + 6

y = 11/18x -88/18 + 108/18

y = 11/18x + 20/18

now let's take the reciprocal of the slope and change the sign,  then we have

y = - 18/11x +20/18  ( coordinates robot can move on )

on the graph I'm attaching the green line is the one where the robot first moves, then the purple one.. is the one it turns 90 ° on to .

Gillmans

Step-by-step explanation:

I feel like gillmans class did better cuz their class didnt have anyone get a score less than 60 but mr athens class had people who got below 50. Although athens class has people over 95 the most were 60-90 while gillmans was 70-90

Answer:

1%

Step-by-step explanation:

24(400) = 9600 = total amt paid

9600 - 8000 = 1600 = amt of interest paid

I = PRT         T = 2 yr

1600 = 8000(2)R

1600 = 16000R

1600/16000 = 1/10 = .01 = 1%

Answer:

This is a ratio table,so therefore there is always a pattern.

Step-by-step explanation:

In order to solve,you have to find the constant in the question,such as 30,40,50,and 60.The constant in this example is 10.When the constant is not even,or the numbers are not even,that's the time you pull out your notebook multiplication chart.Look at the numbers,and see if those numbers are on the chart.If all of them are on the chart,then see if one or both of the multiplicable numbers fall under the category of your variables.If all are under one number,then that number is your answer.

Answer:

[tex]Volume = 960in^3[/tex]

Step-by-step explanation:

Given

Empty Tank

[tex]Length = 24in; Width=10in; Height = 12in[/tex]

When filled with water, the height is:

[tex]Height = 8in[/tex]

Required

Determine how many more cubic inches needed

First, we calculate the difference between the height of the tank and the height of the water.

[tex]H = 12in - 8in[/tex]

[tex]H = 4in[/tex]

The volume of water to full the tank is then calculated as:

[tex]Volume = Length * Width * H[/tex]

[tex]Volume = 24in * 10in * 4in[/tex]

[tex]Volume = 960in^3[/tex]

Answer:

Radius -  4

Apothem -  2

Area - [tex]12\sqrt{3}[/tex] or 20.8

Step-by-step explanation:

Try to draw out my explanation so you know what this looks like.

~~~~

This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...

[tex]12\sqrt{3} \div3 = 4\sqrt{3}[/tex]

Now that we know the side lengths, we can get this started!

~~~~

Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.

4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.

[tex]Small=2\sqrt{3} \\Hypotenuse = 4\sqrt{3} \\Long =6[/tex]

By the way, the formula for the area can be either of the two:

[tex]A= \frac{1}{2} bh\\or\\A = \frac{1}{2} NAS[/tex]

we can easily find the area using the first formula.

[tex]A= \frac{1}{2} (4\sqrt{3} )(6)\\A=12\sqrt{3}[/tex]

The radius is the distance from the center to the corners & the apothem is the distance from the center to a side...

So we can divide the big triangle into a mini triangle at the bottom left/right

The height (small leg) of that triangle would be the apothem

The hypotenuse of that triangle would be the radius.

I did the math really quick because this is getting long. Anyhow, the small leg is 2 so is the apothem, and the hypotenus is 4, so is the radius

Answer:

25 servings

Step-by-step explanation:

to fill one cup, 5 servings would have to be, um... served.

for 5 cups, it would have to be 5 cups in each of the 5 cups, so 5 * 5, which makes 25 servings
