Answer:
[tex]h = \frac{S - 2\pi r ^{2} }{2\pi r} [/tex]Step-by-step explanation:
S = 2πr² + 2πrh
To solve for h move 2πr² to the other side of the equation
That's
2πrh = S - 2πr²
Next divide both sides by 2πr in order to isolate h
That's
[tex] \frac{2\pi rh}{2\pi r} = \frac{S - 2\pi r ^{2} }{2\pi r} [/tex]We have the final answer as
[tex]h = \frac{S - 2\pi r ^{2} }{2\pi r} [/tex]Hope this helps you

A cell phone beeps every 4 minutes. Another cell phone beeps every 5 minutes. What are the first three times that the cell phones beep at the same time?
Answer:
20, 40, 60
Step-by-step explanation:
We can find the LCM by making a list which is my favorite way.
Cell phone number 1: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60
Cell phone number 2: 5, 10, 15, 20, 25, 30, 35 40, 45, 50, 55, 60
Answer:
The first three times that the cell phones beep at the same time are the 20th, 40th and 60th minutes.
Step-by-step explanation:
Let the first cell phone be A, that is, A beeps every 4 minutes
and let the other cell phone be B, that is, B beeps every 5 minutes.
Cell phone A will be at the 4th, 8th, 12th, 16th and 20th minutes while cell phone B will beep at the 5th, 10th, 15th and 20th minutes. Hence, the first time the cell phones will beep together is the 20th minute.
Cell phone A will then beep at the 24th, 28th, 32nd, 36th and 40th minutes while cell phone B will beep at the 25th, 30th, 35th and 40th minutes. The second time the cell phones will beep together is the 40th minute.
Cell phone A will beep at the 44th, 48th, 52nd, 56th and 60th minutes while cell phone B will beep at the 45th, 50th, 55th and 60th minutes. The third time the cell phones will beep together is the 60th minute.
Hence, the first three times that the cell phones beep at the same time are the 20th, 40th and 60th minutes.
how do you dilate a point on a graph?
Answer:
If the point that you are dilating is directly above the point of dilation and you are dilating by 3, you take the distance from the point of dilation and the point you are dilating and you multiply it by 3. That is where you put your new point.

Answer: 2n + 8 = n -3
Step-by-step explanation:
In this scenario we will represent that number by the variable n.
So two times the number will be 2n plus 8 is 2n +8 and it has to equal 3 less that number so it will be n-3.
if there is a strong correlation between two variables the correlation coefficient will be close to -1 or 1 true or false
=================================================
Explanation:
r = correlation coefficient
If r is close to -1, then the points are close to (or some fall on) the same straight line that has a negative slope. We consider this be a strong negative linear correlation.
If r is close to +1 or just 1, then the points are close to the same straight line that has a positive slope. These points would be considered to have strong positive linear correlation.
By "same straight line", I mean the regression line or line of best fit.

If k is a positive integer and n = k(k + 7), is n divisible by 6 ? (1) k is odd. (2) When k is divided by 3, the remainder is 2.
Answer:
1.) Yes
2.) Yes
Step-by-step explanation:
Given that
n = k(k + 7)
If k is a positive integer and n = k(k + 7), is n divisible by 6 ?
(1) k is odd. Yes.
Let assume that k = 3
Then, n = 3(3 + 7)
n = 3 × 10
n = 30.
30 is divisible by 6.
(2) When k is divided by 3, the remainder is 2. That is,
Let k = 5
Then,
5/3 = 1 remainder 2
Substitute k into the equation
n = k(k + 7)
n = 5(5 + 7)
n = 5 × 12
n = 60
And 60 is divisible by 6.
Therefore, the answer to both questions is Yes.

What would be the answer for -2 -12n=-303
Answer:
25.08
Step-by-step explanation:
-12n - 2 = -303
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, n. Do the opposite of PEMDAS.
First, add 2 to both sides:
-12n - 2 (+2) = -303 (+2)
-12n = -303 + 2
-12n = -301
Next, divide -12 from both sides:
(-12n)/-12 = (-301)/-12
n = -301/-12 = 301/12
n = 25.08 (rounded).

A) Kershaw pitched in 32 games in 2011. What was his salary per game in 2011?
B) He pitched in 28 games in 2019. What was his salary per game in 2019? Round to the nearest cent.
C) Did he earn more per game in 2019 than he did for the entire 2011 season?
Answer:
A. $15,625 per game
B. $1,107,142.86 per game
C. he earned $607,142.86 more per game in 2019 than he did for the entire 2011 season
Step-by-step explanation:
His salary in 2011 = $500,000
His salary in 2019 = $31,000,000
A) Kershaw pitched in 32 games in 2011. What was his salary per game in 2011?
Kershaw's salary per game = Total salary / Total number of games
= $500,000 / 32 games
= $15,625 per game
B) He pitched in 28 games in 2019. What was his salary per game in 2019? Round to the nearest cent.
Kershaw's salary per game = Total salary / Total number of games
= $31,000,000 / 28 games
= $1,107,142.8571428
To the nearest cents
= $1,107,142.86 per game
C) Did he earn more per game in 2019 than he did for the entire 2011 season?
$1,107,142.86 per game - $500,000
= $607,142.86
Yes, he earned $607,142.86 more per game in 2019 than he did for the entire 2011 season
Answer:
A. $15,625 - game
B. $1,107,142.86 - game

The traffic lights at three different road crossings change after every 48 seconds 72 seconds and 108 seconds respectivily.If they changed simultaneously at 7:00 am.,at what time will they change simultaneously again
Answer:
07:43: 12 AM
Step-by-step explanation:
Given that:
Traffic lights change after every 48, 72 and 108 seconds.
They changed simultaneously at 7:00 AM.
To find:
At what time, they will change simultaneously again ?
Solution:
For this, we need to find LCM(Least Common Multiple) of the three numbers and then add it to 7:00 AM to find the time they will change together again.
Because LCM of 3 numbers is the least number which is divisible by all 3 numbers.
Let us factorize the numbers and underline the common part:
[tex]48 = \underline{12}\times 4\\72 = \underline{12}\times 6\\108 = \underline{12}\times 9[/tex]
Common part is taken only once and the remaining part is multiplied to it to find the LCM.
So, LCM = [tex]12 \times 4\times 6 \times 9 = 2592[/tex]
In 2592 seconds, they will change together again.
Changing 2592 seconds in minutes:
Let us divide it by 60:
We get 43 minutes 12 seconds.
Let us add it to 7:00AM, we get the following:
So, the time at which they will change simultaneously = 07:43: 12 AM

So keep [tex]\frac{1}{4}[/tex] change your division sign to a multiplication sign, and flip [tex]\frac{9}{10}[/tex] so it becomes [tex]\frac{10}{9}[/tex].
[tex]\frac{1}{4}[/tex]·[tex]\frac{10}{9}[/tex]=[tex]\frac{10}{36}[/tex]
Then you need to reduce your fraction to simplest form.
[tex]\frac{5}{18}[/tex]
Evaluate this expression: 3x + 9x -5
Answer:
12x - 5
Step-by-step explanation:
3x + 9x - 5 can be easily simplified by combining like terms.
3x and 9x are like terms because they both contain the same variable and the same exponent (understood to be 1).
Therefore, because an addition sign separates the two terms, it is expected of you to add the two together. To do this, just add the terms together as you would any other terms.
3x + 9x = 12x
Because the 5 is the only constant in the equation, it cannot be combined with anything else.
The simplified expression is 12x - 5.
