<h3>Question:</h3>

<em>Jon is selling tickets for the school talent show. On the 1st day, he sold 3 senior tickets and 12 child tickets for $195. On the 2nd day he sold 13 senior tickets for $299. Find the price of a senior citizen ticket.</em>

<h3>Answer:</h3>

$23

Create a system of equations to help you solve this problem. The system of equations will look like: 3s + 12c = 195 and 13s = 299. The variable s represents the cost of senior tickets and the variable c represents the cost of children tickets.

$\left \{ {{3s~+~12c~=~195} \atop {13s~=~299}} \right.$

Solve the second equation for the variable s as this is the easiest way to solve the problem. Solve the second equation for s by dividing both sides of the equation by 13 to isolate the variable s.

s = 23

Since the question was only asking for the price of a senior citizen ticket, you are technically done. The first equation was only put there to confuse you or allow you to check your work if you needed to. The price of a senior citizen ticket (variable s) is $23.

Gianni says the lateral area of the square pyramid is 624 in2 Do you agree or disagree with gianni?Use numbers and words to supp

aliina [53]

Answer:

Agree: if lateral area of the square pyramid after calculating the formula:

1/2(Perimeter * slant height) = 624in^2

Disagree if answer is different

Step-by-step explanation:

The question is incomplete without the diagram or the values of the lateral area of the square pyramid.

I would explain how to find it, that way you would be able to know if the area is 624 in^2 or not. I have attached a diagram of a square pyramid.

To know if the Lateral area of the square pyramid that you were given is 624inches square, we would use the formula for the area to determine if it's correct.

Lateral area of the square pyramid formula= 1/2(Perimeter * slant height)

We would first find the perimeter of the base by multiplying the length(l) of one edge by four.

Reason: a square has four equal sides.

P = 4L

Then multiply the lateral slant height (h) by the perimeter = P * h

Then divide your answer by 2

=1/2(P*h)

The lateral slant height is the distance from the top of the pyramid to the edge of the base that bisects one of the triangle faces.

If after calculating the area your answer is 624in^2 you would state you agree with Gianni but if the answer you got is different, you would state you disagree.

Then you provide the correct answer.
