Hey 20 points for the first person to show work and answer this​

Mathematics
1 answer:
Harrizon [31]3 years ago
5 0

Step-by-step explanation:

First, the pizza is 18 inches in diameter, so

d = 18

and, because the radium is half of the diameter,

r = 9

<u>Note that the units are inches.</u>

Using the equation

a = \pi  r ^{2}

where a is the area of a circle, we know that the area of the whole pizza is approx.254.5 square inches. Divide by 8 to find the area of 1/8 of a pizza. Each slice will have an area of approx. 32 square inches. For a precise result, the answer is

a(s)=  \frac{(\pi  \times 9^{2})}{s}

where a(s) is the area of a slice of pizza, and s is the total number of slices, given they are equal in size.

ohaa [14]

Given :

On the first day of ticket sales the school sold 10 senior tickets and 1 child ticket for a total of $85 .

The school took in $75 on the second day by selling 5 senior citizens tickets and 7 child tickets.

To Find :

The price of a senior ticket and the price of a child ticket.

Solution :

Let, price of senior ticket and child ticket is x and y respectively.

Mathematical equation of condition 1 :

10x + y = 85    ...1)

Mathematical equation of condition 2 :

5x + 7y = 75    ...2)

Solving equation 1 and 2, we get :

2(2) - (1)   :

2( 5x + 7y - 75 ) - ( 10x +y - 85 ) = 0

10x + 14y - 150 - 10x - y + 85 = 0

13y = 65

y = 5

10x - 5 = 85

x = 8

Therefore, price of a senior ticket and the price of a child ticket $8 and $5.

Hence, this is the required solution.
