somehow i got 146.729521 inches...

Answer:127.5in

Step-by-step explanation:

use V=2/3(pi)r^2

863=2/3(pi)(r^2)

isolate the radius

then you get r=63.8

63.8*2= 127.5in

Answer:

192.4 m^2

Step-by-step explanation:

See the attached image.

The area of a regular polygon is  [tex]A=\frac{1}{2}ap[/tex]  where p is the perimeter and  a  is the apothem (the distance from the center to the midpoint of a side).

The perimeter is  p = 10(5) = 50m.  This is a huge decagon!

Calculate the measure of angle KGL.  In a decagon, the total of all interior angles is 180(10-2) = 1440 degrees.  That makes one of the interior angles 1440 / 10 = 144, and angle KGL is half of that, 72 degrees.

To find  a, use a trigonometric ratio in right triangle GKL.  GL = 2.5, half the length of side GH.

[tex]\tan{72^\circ} = a/2.5\\\\a=2.5\tan{72^\circ} \approx 7.6942[/tex]

The area of the decagon is

[tex]A=\frac{1}{2}(7.7.6942)(50) \approx 192.4[/tex]

32 students on the fifth bus, 192 students in total, 24 teachers in total.

Step-by-step explanation:

40 × 4 = 160

4/5 of 40 = 32

1/8 of 192 (the total number of students) = 24

the answer of this question is 24

Answer:

$61.20

Step-by-step explanation:

15% of 72 is 10.8 (because 72 x 0.15 = 10.8)

So, the markdown is $10.80 off of $72.00

To get the new sale price, we just subtract the markdown ($10.80) from the original price ($72.00)

$72.00 - $10.80 = $61.20

So, the answer is $61.20

I hope this helps! :)

Answer:

y=-5/4x-4.

Step-by-step explanation:

parallel lines have to have the same slope so they don't intersect each other

original equation with the same slope and rewrite it using point slope form:

y-y1=-5/4(x-x1) now Substitute the point(-4,1)

y-1=-5/4(x-(-4))

y-1=-5/4(x+4)

Now we can distribute the -5/4 and add 1 to the right to get our final slope-intercept form:

y-1=-5/4x-5

y=-5/4x-4.

The parallel line of y=-5/4x+7 that passes through point (-4,1) is y=-5/4x-4.

Answer: y=-5/4x-4.

Answer:

the surface area is not equal to 296 sq ft.

Step-by-step explanation:

There are total six faces of the given rectangular prism

Area of the top and bottom face is equal to 288 Sq ft

Area front face and the face at the back = 2 * 2 * 144 = 576 Sq. ft.  

Area of the other two sides is  = 2 * 2 * 144 = 576 Sq. ft.

The total surface area of the prism is 576 +576 + 288 = 1440 Sqft

No, the surface area is not equal to 296 sq ft.

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

Explanation:

We have 9 men and we want to select 2 of them. The order doesn't matter. If order did matter, then we would have 9*8 = 72 permutations. Since order doesn't matter, we have instead 72/2 = 36 combinations. The reason why order doesn't matter is because no person outranks another on a committee. Any given seat is the same as anyone else. This is excluding any chairperson of course.

So we have 36 ways to select the men. There are also 36 ways to select the women as well for the exact same steps as listed above. This is due to there being 9 women total and we're selecting 2 of them.

Since there are 36 ways to select the two men, and 36 ways to select the two women, this leads to a total of 36*36 = 1296 different committees

It might help to think of a table that has 36 rows and 36 columns. Each row could represent a different two-person group of men while each column represents a different two-person group of women. The intersection of a given row and column would then form a unique four-person committee. So that may help visually show why there are 36*36 = 1296 different committees (each committee is an inner cell).

Answer:

f(5) = 2

Step-by-step explanation:

it says to use the function (-x+3) for when x is bigger than 2

f(x) = (-x) + 3 replace x with 5

f(5) = (-5) + 3 and f(5) = 2

Answer:

[tex]f(5)=-2[/tex]

Step-by-step explanation:

In piecewise functions, we need to find the applicable equation to use based on our value of [tex]x[/tex]. [tex]f(5)[/tex] denotes [tex]x[/tex] as 5. Since [tex]5>2[/tex], we will use the equation that corresponds to [tex]x>2[/tex], which is [tex]-x+3[/tex].

Substituting [tex]x=5[/tex], we have:

[tex]x=-(5)+3,\\x=-5+3,\\x=\boxed{-2}[/tex]

Step-by-step explanation:

x = √(100+66)

=√(166)

Answer:

y=2x

Step-by-step explanation:

slope = rise/run = 2/1 = 2

The solution is, y = -1/3 x + 5 this equation represents the given graph.

In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.

here, we have,

The horizontal axis is called the x-axis.

And the vertical one is the y-axis.

Points are written as xy pairs in parentheses, like so: (x, y).

Now, just locate the position on x-axis as well as in y-axis and finally plot where these points meet.

Proof :

(0, 5) and ( 15, 0) these are the points where the graph is plotted.

y = -1/3 x + 5

put x= 0 and find y

y = 0 + 5

y = 5

put y = 0 and find x

0 = -1/3 x + 5

-5 = -1/3 x

x = 15

So, now we get the same points i.e, (0, 5) and ( 15, 0) as plotted in the given graph.

Hence, we can say that  y = -1/3 x + 5 this equation represents the given graph.

Answer:

b= 25

Step-by-step explanation:

a+b =72

a-b = 22

2a = 94

DBS(Divide Both Side) by 2

a = 47

=47 +b =72

and:

47 -b =22

subtract 47 from both sides:

b=25
