The diameter of a volleyball is 15.5 find its radius and volume​

The Diameter Of A Volleyball Is 15.5 Find Its Radius And Volume

Answers

Answer 1

Step-by-step explanation:

diameter = 2 × radius.

15.5 = 2 × r.

r = 15.5 ÷ 2.

r = 7.75.

volume = πr²

v = π × 7.75².

v = 188.7.

I ain't confident about the volume answer but, the diameter answer is correct.

hope it helps. :)

Combine the like terms to create an equivalent expression:
-3.2 - 6+ (-1)

Answers

Answer:

-3x + (-7)

Step-by-step explanation:

First you want to find the like terms, in this case it is the numbers without a coefficient, (6 and -1). So you are then left with -6+(-1) which equals to -6-1 = -7. Finally, you combine the number with the coefficient (-3x) with the number without it (-7) and you get -3x-7

Answer:

-3x-7

The perimeter of the worksheet is 28 inches. The worksheet is 6 inches tall. How long is it?

Answers

Answer:

The anwser is that it's 8 inches

Step-by-step explanation:

How i figured this out is since it's a woksheet,

I can guess that its a rectangle or quadrtilateral. One side is 6 inches, so the exact opposite side is also the same size, so we would have to double the 6 to 12. We know that the perimeter is 28, we can subtract 28 from 12 so that we can find out how long it is. We get 16 from 28-12 and we need to half the amount to find out how long one side is. let me know if you have any more quesitons because i dont know if i explained it well

find the value of x.

Answers

Answer:

x = 4

Step-by-step explanation:

Given a line parallel to a side of the triangle and intersecting the other 2 sides then it divides those sides proportionally, that is

[tex]\frac{10-x}{x}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )

3x = 2(10 - x)

3x = 20 - 2x ( add 2x to both sides )

5x = 20 ( divide both sides by 5 )

x = 4

For an employee training, the employee to instructor ratio is 24 to 2. If there are 39 instructors for the training, how many employees participated in the training?

Answers

Answer:

468

Step-by-step explanation:

Employee : instructor = 24 : 2

If there are 39 instructors

Employee = x

Employee : instructor = x : 39

Equate both ratios

24 : 2 = x : 39

24/2 = x/39

Cross product

24 * 39 = 2 * x

936 = 2x

x = 936/2

x = 468

Employees = x = 468

If a penceil has 25 grams and a apple has 75 grams more then the penceil how many grams is the apple

Answers

Answer:

The answer is 100

Step-by-step explanation:

It's 100 because it's saying that the apples is 75 more grams than the pencil. So we do 25 grams plus 75 grams which gets us 100. If your wondering where I got the 25 from it's from the amount of the pencil.

100 because when you add 25 to 75 you get 100. You add these two together because the apple is 75 grams more than the pencil so you add to find the product of the apple.

What is the slope? What is the y-intercept? What is the equation of line (write is slope intercept form)?

Answers

Answer:

[tex]2x+1[/tex]

Step-by-step explanation:

Use the rise over run method.

[tex]\frac{rise}{run}[/tex] = [tex]\frac{2}{1}[/tex]

To find the y-intercept, look where the line crosses on the y-axis. In this case, the line crosses on 1.

Now plug in the numbers:

[tex]y=mx+b[/tex]

m = slope

b = y-intercept

[tex]y=2x+1[/tex]

[tex]2x+1[/tex]

Hence the equation of the line is, [tex]2x+1[/tex].

Answer: Figure A to Figure B is a scale factor of 0.5

Step-by-step explanation:

It's not too hard to figure out scale factor, since the two shapes are the same aside from their scale. Notice how Figure A is 4 units tall, and that Figure Bis 2 units tall. From one figure to another, use the equation Figure B/Figure A to find the scale factor. Although you won't really need to memorize all this, you can count the amount of units on your fingers and figure it out from there.

Let f() = 3x - 1 and g(x) = 2x + 3 and find f(g(3))

Select the correct

response

f(g(3)) = 21

f(g(3)) = 19

f(g(3)) = 26

f(g(3)) = 17

Answers

Answer:

f(g(3)) = 26

Step-by-step explanation:

f(g(3))

g(3) = 2x + 3

= 2(3) + 3

= 6 + 3

= 9

f(9) = 3x - 1

= 3(9) - 1

= 27 - 1

= 26

plug in 3 for g(x) which is 9 then plug in 9 for f(x) which is 26

Answers

Answer:

36

Step-by-step explanation:

The formula of LCM is LCM(a,b) = ( a × b) / GCF (a,b)

The Greatest Common Factor of (9,12) = 3

Therefore

LCM of 9 and 12 = (9 × 12) / 3

= 108/3 = 36

LCM of 9 and 12 = 36

Irrespective of the method, the solution to our question LCM of 9 and 12 is the same.

Therefore, LCM of 9 and 12 is 36
