Answer:
6.5 inches
Step-by-step explanation:
Finding the height of the cylinder
Volume = 936 π in³
diameter = 24 inches
r = 24 ÷ 2
r = 12 inches
Volume = 936π
πr²h = 936π

Write the equation of the circle below to complete the square. Also determine the area of the circle.
Answer: [tex](x-7)^2+(y+2)^2=11^2[/tex] ; [tex]A=121\pi[/tex]
Step-by-step explanation:
I have never done a problem like this, so this is my first time attempting it.
The standard form for the equation of a circle is:
[tex](x-a)^2+(y-b)^2=r^2[/tex]
Begin by grouping the 'x' terms and 'y' terms:
[tex](x^2-14x)+(y^2+4y-68)=0[/tex]
Complete the square for the second polynomial:
[tex](\frac{b}{2} )^2=(\frac{4}{2} )^2=4[/tex]
[tex](x^2-14x)+(y^2+4y+4-4-68)=0[/tex]
[tex](x^2-14x)+(y^2+4y+4)-4-68=0[/tex]
[tex](x^2-14x)+(y^2+4y+4)-72=0[/tex]
[tex](x^2-14x)+(y+2)^2-72=0[/tex]
Do the exact same process with the other polynomial:
[tex](x^2-14x-72)+(y+2)^2=0[/tex]
Complete the square:
[tex](\frac{14}{2} )^2=49[/tex]
[tex](x^2-14x+49-49-72)+(y+2)^2=0[/tex]
[tex](x^2-14x+49)-49-72+(y+2)^2=0[/tex]
[tex](x^2-14x+49)-121+(y+2)^2=0[/tex]
[tex](x-7)^2-121+(y+2)^2=0[/tex]
Bring the 121 to the other side to get:
[tex](x-7)^2+(y+2)^2=121[/tex]
[tex](x-7)^2+(y+2)^2=11^2[/tex]
The above expression is the equation of our circle in standard form. It is centered at the coordinates (7, -2) and has a radius of 11 units. The area of a circle if given by:
[tex]A=\pi r^2=121\pi[/tex]

For A: The options are between 0.40 and 0.45. A is plotted on the 3rd line from 0.40. That makes the answer 0.43.
For B: It is in the middle of 0.45 and 0.50. It is plotted on the 4th line from 0.45, which is 0.49.
A = 0.43; B = 0.49
Breanna and Courtney kept track of the total distance they rode their blcycles over the summer. With one week remaining in the summer, Breanna had ridden her blcycle b miles, and Courtney had ridden her bicycle c miles. During the last week of summer Breanna rode her bicycle 200 miles and Courtney rode her bicycle 500 miles. . For the entire summer, Courtney recorded 180 mlles more than Breanna recorded. Enter an equation that can be used to show that Courtney rode her bicycle 180 mlles more than Breanna rode her bicycle
The equation that shows Courtney rode 180 mlles more than Breanna rode is c = b + 180
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let b represent the number of miles rode by Breanna and c represent that of Courtney.
c = b + 180
The equation that shows Courtney rode 180 mlles more than Breanna rode is c = b + 180

I need this by today please explain it clearly and also say the equation, Thank you (:
Answer:
1. x - 12 = 14 {brother's age minus 12 equals sister's age}
x = 26 {added 12 to each side}
Your brother is 26.
2. x+8.95=21.35
now you must subtract 8.95 by both sides which equals x =12.4
3. 29 compact cars.
The total number of vehicle is 37. So you can just subtract 37 by 8 which gives 29.
4. x +73=95
subtract both sides by 73. which equals 22
5. $160 He originally spent $123.45 and was left with $36.55 you just add both numbers and that's what you get altogether.
6. X-225=548
Solve for x
Add 225 to both sides. So x - 753

only one question, correct answer gets brainliest
Answer:
CA ≈ 10 cm
Step-by-step explanation:
Since we know 2 sides and 1 angle we can use the Law of Cosine to find the third side.
CA = √(AB²+CB²- 2· AB· CB· cos 50°)
CA = √(7² +13² -2·7·13· cos 50°)
CA = √(49 +169 -116.987345)
CA = √101.012655
CA = 10.0505
CA ≈ 10 cm
1. Mrs. Rodger got a weekly raise of $145. If she gets paid every other week, write an integer describing how the raise will affect her paycheck.
weekly raise= $145
to find:an integer describing how the raise will affect her paycheck.
solution:Let the 1st paycheck be x (integer).
Mrs. Rodger got a weekly raise of $ 145.
So after completing the 1st week she will get $ (x+145).
Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.
= $ (x + 145 + 145)
= $ (x + 290)
therefore, in this way end of every week her salary will increase by $ 145.

Step-by-step explanation:
The price of a bus ticket to Saskatoon is $180. This bus has 56 seats. The bus company is considering dropping this bus fare as part of a promotion to increase the ridership on that route.
The buses has only been at half capacity lately. The companies research shows that for every 5$ decreases they will gain 2 more riders.
1. Define variable and set up an equation to represent his scenario
2. What is the maximum revenue the bus company can earn and what will be the cost of a ticket when the revenue is at a maximum
The bus tickets and price are illustrations of a quadratic function, and the maximum revenue the bus company can earn is $5107.6
The variables of the scenarioThe variable representation used in this scenario are:
Let x represents the number of seatsLet y represents the total amountThe maximum revenueThe price is given as:
Price = $156
The number of seats is given as:
Seats = 56
When the bus is at half capacity, we have:
Seats = 28
As the price decreases by $5, the rider gains 2 more.
So, the revenue equation is:
y = (156 - 5x)(28 + 2x)
Expand
y = 4368 - 140x + 312x - 10x²
Differentiate
y' = 0 - 140 + 312 - 20x
Evaluate the sum
y' = 172 - 20x
Equate to 0
172 - 20x =0
Add 20x to both sides
20x = 172
Divide both sides by 20
x = 8.6
Substitute x = 8.6 in y = (156 - 5x)(28 + 2x)
y = (156 - 5 * 8.6)(28 + 2 * 8.6)
Evaluate
y = 5107.6
Hence, the maximum revenue the bus company can earn is $5107.6
