The volume of the given hemisphere is 59131.7 inches³.

What is a hemisphere?

Hemisphere is the exact one-half of the sphere.

given, diameter of the hemisphere is = d = 60.9 inches

Therefore, radius = d/2 = 60.9/2 inches = 30.45 inches.

Hence, the volume = (2/3) × π × r³ =  (2/3) × π × (30.45)³ inches³ = 59131.7 inches³.

Answer:

15

Step-by-step explanation:

The x-intercepts -3 and -5 are also "roots" of the polynomial.  The corresponding factors are (x + 3) and (x + 5).  Multiply the constants together:  3*5 = 15.  This is the desired constant term.

Note that your f(x) = x2 + 8x +   should be written   f(x) = x^2 + 8x +       ...    The " ^ " denotes exponentiation.

Check:  Multiply (x + 3) and (x + 5) together and compare the result to the given polynomial with constant term 15:

f(x) = (x + 3)(x + 5) = x^2 + 3x + 5x + 15 = x^2 + 8x + 15.  This matches!

The sum of the numbers 13 + 13 + 13 is 39.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given expression is,

13 + 13 + 13

Here 13 is added to itself three times.

When 13 added to 13, we get 13 + 13 = 26

Again if we add the number 13 to 26, we get 13 + 26 = 39

13 + 13 + 13

= 26 + 13

= 39

This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.

Hence the number 13 added to itself three times gives 39.

Answer:

h = 72

Step-by-step explanation:

Given that h varies inversely with g then the equation relating them is

h = [tex]\frac{k}{g}[/tex] ← k is the constant of variation

To find k use the condition h = - 24 when g = 3 , then

- 24 = [tex]\frac{k}{3}[/tex] ( multiply both sides by 3 )

- 72 = k

h = - [tex]\frac{72}{g}[/tex] ← equation of variation

When g = - 1 , then

h = - [tex]\frac{72}{-1}[/tex] = 72

4) H

Step-by-step explanation:

Perimeter of a triangle formula:

P = a + b + c

1)

P = x + 6 + 3x + 2 + 2x + 4

P = 6x + 12

2)

P = 6x + 4 + 7x + 1 + 5x + 7

P = 18x + 12

3)

P = 4x - 3 + 3x + 5x - 6

P = 12x - 9

4)

P = 6x - 8 + 3x + 7 + 5x - 3

P = 14x - 4

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{2}{3}[/tex] , then

y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation

To find c substitute (3, - 4) into the partial equation

- 4 = 2 + c ⇒ c = - 4 - 2 = - 6

y = [tex]\frac{2}{3}[/tex] x - 6 ← in slope- intercept form

Multiply through by 3 to clear the fraction

3y = 2x - 18 ( subtract 2x from both sides )

- 2x + 3y = - 18 ( multiply through by - 1 )

2x - 3y = 18 ← in standard form → D

Answer:

16 is the median

Step-by-step explanation:

By definition, the median is the mid value or the middle number of a given data set

Firstly, we have to arrange the numbers in ascending or descending order

What we have as the count of the numbers here is 9

So the middle number is the 5th term counting from either sides

As we can see, the fifth term here is the number 16

Answer:

a. x = 22

b. Perimeter = 100

Step-by-step explanation:

a. Based on the proportionality theorem, we have the following:

(2x - 4)/8 = (36 - 6)/6

(2x - 4)/8 = 30/6

(2x - 4)/8 = 5

Cross multiply

2x - 4 = 8*5

2x - 4 = 40

2x = 40 + 4

2x = 44

x = 44/2

x = 22

b. Perimeter of ∆JKL = KJ + KL + JL

KJ = 2x - 4 + 8

Plug in the value of x

KJ = 2(22) - 4 + 8

KJ = 44 - 4 + 8 = 48

KL = 36

JL = 16

Perimeter = 48 + 36 + 16

Perimeter = 100
