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:

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]

Answer:

(Choice C) C \dfrac27 7 2 ​ start fraction, 2, divided by, 7, end fraction

Step-by-step explanation:

2÷7=2, divided by, 7, equals

(Choice A) A \dfrac97 7 9 ​ start fraction, 9, divided by, 7, end fraction

(Choice B) B \dfrac72 2 7 ​ start fraction, 7, divided by, 2, end fraction

(Choice C) C \dfrac27 7 2 ​ start fraction, 2, divided by, 7, end fraction

(Choice D) D \dfrac29 9 2 ​

2÷7=2, divided by, 7, equals (Choice C) C \dfrac27 7 2 ​ start fraction, 2, divided by, 7, end fraction

2 ÷ 7

= 2/7

= 0.2857142857142

= 0.29

Answer:

Step-by-step explanation:

9.3 times 7 equals 65.1

65.1 time the 5 sides equals 325.5

325.5 plus the 84 for the base equals 409.5 ft^2

Answer:

(-4, 2)

Step-by-step explanation:

5x + 15y = 10 ---› Eqn. 1

5x - 10y = -40 ---› Eqn. 2

Subtract the eqn 2 from 1 to eliminate the x variable

Thus:

25y = 50

Divide both sides by 25

y = 50/25

y = 2

Substitute y = 2 into eqn 1.

5x + 15y = 10 ---› Eqn. 1

5x + 15(2) = 10

5x + 30 = 10

Subtract 30 from each side

5x = 10 - 30

5x = -20

Divide both sides by 5

5x/5 = -20/5

x = -4

Solution would therefore be (-4, 2)

Answer:

4 more than the product of 9 and a number is 36. /// 9n + 4 = 36

9 times the sum of a number and 4 is 36. /// 9(n + 4) = 36

4 times the sum of a number and 9 is 36. /// 4(n + 9) = 36

9 subtracted from the product of 4 and a number is 36. /// 4n - 9 = 36

Answer:

the true statement is D. sin A = cos C

it's because,

statements A and B do not match and as for statement C, angle B is not included in trigonometric ratios

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.

Step-by-step explanation:

Answer:

question? lol

Step-by-step explanation:

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

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:

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.

Answer:

x = 54°

Step-by-step explanation:

(5-2)·180° = 540°, which is the total amount of degrees inside a pentagon

if it's regular then each angle is equal so m∡B = 540/5 or 108°

∠DBC ≅ ∠CDB because ΔCBD is isosceles

half of 108 is 54°

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

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

and

-b = -25 MBS(Multiply Both Side) by-1 ....>b=25
