Answer:

BDCEA

Step-by-step explanation:

A: area of the triangle = \frac{1}{2}bh = \frac{1}{2}(10)(4) = \frac{1}{2}(40) = 20  ft^{2} \\

B: area of the rectangle + area of the triangle =(5*6) + \frac{1}{2}(5)(6) = 30+15=45 ft^{2}

C: area of the rectangle + area of the trapezoid = (6*2) + \frac{1}{2}(b_{1} +b_{2})(h) = (6*2)+ \frac{1}{2}(2+5)(5) = 12+\frac{1}{2}(35) = 29.5 ft^2

E: area of the triangle = \frac{1}{2}bh = \frac{1}{2}(14)(4) = \frac{1}{2}(56) = 28  ft^{2} \\

D: area of the rectangle + area of the triangle = (8*3) + \frac{1}{2}(8)(2) = 24+8=32 ft^{2}

Tickets for a school carnival cost 10$ for adult and 5 for children. last Saturday carnival sold 170 tickets worth a total of $1
riadik2000 [5.3K]

70 adults and 100 children attended the carnival.

Step-by-step explanation:

Given,

Cost of each adult ticket = $10

Cost of each child ticket = $5

Total tickets sold = 170

Total revenue generated = $1200

Let,

Number of adults = x

Number of children = y

According to given statement;

x+y=170      Eqn 1

10x+5y=1200    Eqn 2

Multiplying Eqn 1 by 10

10(x+y=170)\\10x+10y=1700\ \ \ Eqn\ 3

Subtracting Eqn 2 from Eqn 3

(10x+10y)-(10x+5y)=1700-1200\\10x+10y-10x-5y=500\\5y=500

Dividing both sides by 5

\frac{5y}{5}=\frac{500}{5}\\y=100

Putting y=100 in Eqn 1

x+100=170\\x=170-100\\x=70

70 adults and 100 children attended the carnival.
