Answer:
300 / 2 = 450 / x
x = 900 / 300
x = 3 inches
Step-by-step explanation:
The equation is the given one:

Which is the same as:

And the interval of the angle θ must be (0°,90°) so, 2θ must be (0°,180°).
So the statement is True.
If 9/10 tons of gravel got spread over 3 feet, then how much gravel is on each foot? Well, it's a ratio.
9/10 tons : 3 ft
So, we divide each side of the ratio by 3.
3/10 tons : 1 ft.
So, that 3/10 tons of gravel on each foot of road.
Answer=10 10gram weights
10*10grams=100grams
therefore the weight would be even on both sides
