Answer:

126 parts in 9 and a half hours

you can work this out by doing 540 divided by 240

now, multiply 56 by 2.25.

the answer is 126 parts

Answer:

x = 5

Step-by-step explanation:

using the sine or cosine ratio in the right triangle and the exact value

sin30° = \frac{1}{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{x}{10} = \frac{1}{2} ( cross- multiply )

2x = 10 ( divide both sides by 2 )

x = 5
