Answer:
40units²
Step-by-step explanation:
find the shapes you know the formula of. There's two shapes a rectangle and a trapezoid.
do the formula for rectangle
A = bh
A = 8×2
A = 16
Now the formula for Trapezoid
A = 1/2h(b+b)
A = 1/2×4(4+8)
A = 1/2×4(12)
A = 1/2(48)
A = 24
16+24 = 40
Given, y varies directly as x
So,

Where c is a constant
When y equals 5 when x is 8
So,

So, the relation between y and x

now , when x = 9
Substitute with x to find y

So, the answer is option 2. y = 45/8
Answer:
There were 423 adult tickets sold.
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 65 = the number of student tickets sold
x + x + 65 = 715
2x = 715
x = 357.5
x + 65 = 422.5 (round up)
Answer:
4.4
Step-by-step explanation:
16.8 was for 4 hour
divide 4 by 16.8
you get 4.2 per hour
so you need 1 hour
1 hour would be 4.2
temp would be -4.2 at 9pm
Area of rectangle is 7x9 which is 63
Area of the square=5x5 which is 25
So area is: 63-25=38
