Answer:
2
Step-by-step explanation:
Vertical angles have equal measure so:-
9x + 12 = 3x + 24
6x = 12
x = 2
Answer:
<u>39.28cm^2 </u>
Step-by-step explanation:
Simple work out the area of a circle and halve it.
3.142xr^2
3.142x5^2 = 78.55 cm^2 (Full circle area)
Now we must halve that answer to get the semicircle.
78.55/2 = 39.275 cm^2
However, we need it to 2dp. Therefore the answer is 39.28cm^2
Answer:

Answer:
4.5 hours
Step-by-step explanation:
let t be the time elapsed
Therefore, we can set up a system of equations and solve accordingly
2t + 16.5 = 4t + 7.5
2t = 9
t = 4.5 hours more till they paint the same amount in square feet
