To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.

Area = (8+12)/2 = 20/2 = 10

10 x 9 = 90 square centimeters.

The cost of a ticket to the circus is $14.00 for children and $32.00 for adults. On a certain day, attendance at the circus was

Evgesh-ka [11]

400 children and 600 adults bought tickets.

Step-by-step explanation:

Given,

Cost of one child ticket = $14

Cost of one adult ticket = $32

Total attendance = 1000

Revenue generated = $24800

Let,

x be the number of children.

y be the number of adults.

According to given statement;

x+y=1000 Eqn 1

14x+32y=24800 Eqn 2

Multiplying Eqn 1 by 14

$14(x+y=1000)\\14x+14y=14000\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(14x+32y)-(14x+14y)=24800-14000\\14x+32y-14x-14y=10800\\18y=10800\\$

Dividing both sides by 18

$\frac{18y}{18}=\frac{10800}{18}\\y=600$

Putting y=800 in Eqn 1

$x+600=1000\\x=1000-600\\x=400$

400 children and 600 adults bought tickets.

OLga [1]

Answer:

Each sweater costs $8.30

Step-by-step explanation:

j = jeans

s = sweater

3j + 3s = 105.69

3(26.93) + 3s = 105.69

80.79 + 3s = 105.69

-80.79 -80.79

3s = 24.9

/3 /3

s = 8.3 ($8.30)

Check:

3j + 3s = 105.69

3(26.93) + 3(8.3) = 105.69

80.79 + 24.9 = 105.69

105.69 = 105.69
