Find the surface area of the cylinder in terms of ​.

Answers

Answer 1
Answer:

The surface area of the cylinder=  2 π * r^2

Step-by-step explanation:

The surface area of each end and the surface area of the side of the cylinder are added to get surface area of a cylinder.

We know that each end of the cylinder is a circle.

So the surface area of each end of the cylinder is π * r^2

Here, r is the radius of the end

There are two ends, so their combined surface area= 2 π * r^2

The surface area of the cylinder=  2 π * r^2

Albert is organizing an end of term party. The cost of renting a hall for an evening is $100. The cost of food is $8 per person. How much will the party cost if 20 people attend? 50 people attend? Write an algebraic expression for the cost of the party if n people attend. Suppose Albert decides to hire a DJ for the party. The DJ charges $250 for the evening. What is the new cost of the party when n people attend? Suppose the cost of food increases by $2 per person. Write an expression for the total cost of the party with a DJ for n people. The new food price is in effect. How much will the party with a DJ cost for 40 people? Show your work.

Answers

Algebraic expression: 100+8n=x
cost if 20 people attend: 100+8*20 = 100+160
cost if 50 people attend: 100+8*50 = 100+400
New cost of the party when 'n' people attend:100+250+8n=x
Cost for party with 40 people and dj:100+250+n(8+2)=x

Solve 5x - 3y = 9 for y.

Answers

5x - 3y = 9
5x = 9 + 3y
5x - 9 = 3y 
( 5x - 9 ) / 3 = y
y = ( 5 / 3x ) - ( 9 / 3 ) ( I just split the common denominator to individual parts ) 
y = 5 / 3x - 3

The solution is y = (5x - 9) / 3

To solve the equation 5x - 3y = 9 for y, we need to isolate the variable y on one side of the equation.

Step 1: Move the term with y to the other side of the equation.

Subtract 5x from both sides of the equation:

5x - 3y - 5x = 9 - 5x

This simplifies to:

-3y = 9 - 5x

Step 2: Divide both sides by -3 to solve for y:

y = (9 - 5x) / -3

Therefore, the solution for y is:

y = (-9 + 5x) / 3

You can also express the solution as:

y = (5x - 9) / 3

Either form represents the solution for y in terms of x for the given equation.

What is 22/55 in simplest form

Answers

your answer would be 2/5 because u divide both number by 11.
the answer is 2/5 because you can divide the top and the bottom by 11 and get 2 for the top and 5 for the bottom, but you can't divide any number to the fraction any more making it in the simplest form.
