Answer:
69cm squared
Step-by-step explanation:
Area of the rectangle: 8*6= 48
Area of the semicircle: 1/2*6*3=9
Area of triangle: (12-8)*6*1/2=
4*6= 24
24*1/2=12
Area of figure: 48+9+12=69
To set this up you need to create the equation, the total cost is $22.69, so that will be on one side of the equation. The other side will be the flat rate 3, plus the 11 cents per minute.
22.69 = 0.11x +3
To solve this we need to subtract 3 from both sides, and then divide the total by 0.11 to get x alone:
22.69 = 0.11x +3
19.69 = 0.11x
x =179
So David rode the ride for 179 minutes. (Dividing by 60 will give you the number of hours since there is 60 minutes in 1 hour. So it’s about 3 hours.)

Answer:
x=3
Step-by-step explanation:
Equation: x/10=30/100
Simplify 30/100 to make things easier.
x/10=3/10
Since the denominators are already the same, x has to be 3.
Hope this helps!! :D
