PLEASE ANSWER ASPif The Volume Of The Cylinder Is 141.3 In^ 3 , What Is The Radius Of The Base Of The

Answers

Answer 1

Answer:

r = 3 in.

Step-by-step explanation:

vol = Bh   where B is the area of the base and h is the height of the cylinder

The base is a circle so

B = [tex]\pi r^{2}[/tex]    h = 5

141.3 = 3.14(5)[tex]r^{2}[/tex]

        = 15.7[tex]r^{2}[/tex]

[tex]r^{2}[/tex] = 141.3/15.7 = 9

r = 3 in.

Explanation:
#1 : I eliminated the x value which will leave me with the y value.

#2: now that you have the y value,, to look for the x value, pick one equation from the equations given. (I used 2x + 4y = 5)

#3: now put your y value into the equation in order to get the x value. (2x + 4(3) = 5)

#4: now just solve for x.

Answer:

9a^4b^10 ( 4 - 9a^12b^20)

Step-by-step explanation:

The greatest common factor of the two terms is 9a^4b^10

You can now remove the greatest common factor outside the brackets.

Inside the brackets, you place the value obtained by dividing 36a^4b^10- 81a^16b^20 by 9a^4b^10

That is = 4 - 9a^12b^20

Please note that the laws of indices i used for the above division is: n^a divided by n^b = n^(a-b)

Now, the factorised answer for your question =  9a^4b^10 ( 4 - 9a^12b^20)

Which numbers are solutions to the equation 30=x2

x is equal to square root of 30
x=900
x is equal to 900
x=−15
x is equal to negative 15
x=−30−−√
x is equal to negative square root of 30
x=−900

Answers

Answer:

x = +√30

Step-by-step explanation:

Please write 30 = x squared as 30 = x^2.

If x^2 = 30, there are two solutions:  x = +√30 and x = -√30.

Several possible answers are given.    x=30−−√ is closest to the correct one, but must be written as x = √30.  Please ask someone how to find the "√" operator in Brainly.  Or, just write "sqrt(      )" instead.

The equation 3x – 2y = 18 is in slope intercept
form.
If the y variable was isolated, it would be in
1
form.
(Use all lowercase letters when writing the answers)

Answers

Given:

The equation is:

[tex]3x-2y=18[/tex]

To find:

The slope intercept form of the given equation.

Solution:

Slope intercept form of a line is:

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

Where, m is slope and b is y-intercept.

We have,

[tex]3x-2y=18[/tex]

It is not in the slope intercept form.

We need to isolate variable y to get the slope intercept form.

The given equation can be rewritten as:

[tex]-2y=-3x+18[/tex]

[tex]y=\dfrac{-3x+18}{-2}[/tex]

[tex]y=\dfrac{-3x}{-2}+\dfrac{18}{-2}[/tex]

[tex]y=\dfrac{3}{2}x-9[/tex]

Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{3}{2}x-9[/tex].

For which of the following is x = -5 a solution? Select all that apply.

Answers

Answer:

Options 2, 3, 4, 5 are the solutions.

Step-by-step explanation:

Option 1).

x + 10 = -5

x = -10 - 5

x = -15

Therefore, x = -5 is not the solution.

Option 2).

-x² + 50 = 25

-x² = 25 - 50

-x² = -25

x² = 25

x = ±5

Therefore, x = -5 is a solution

Option (3)

|2x| = 10

2x = ± 10

x = ± 5

Therefore, x = -5 is a solution.

Option (4)

x < 0

Since, -5 < 0

Therefore, x = -5 is a solution.

Option (5)

2x < 10

x < 5

Since, -5 < 5

Therefore, x = -5 is a solution.

Options 2, 3, 4, 5 are the solutions.
