Answer:
0.286
Hope that helps!
Step-by-step explanation:
Rate = (150 miles)/(3 hrs) = 50 mph
so . . .
(50 mph)*(time) = 400 miles
*divide both sides by 50 mph
time = (400 miles)/(50 mph) = 8 hrs
time = 8 hrs
74 acres of old-growth are there in the forest
Step-by-step explanation:
To answer the question, we need to calculate the 0.2% of 37,000.We can calculate this stating that exists a linear relationship between the percentage and the number of acres. We also need to state that 37,000 acres are the 100% of the acres.

We find that if 37,000 acres are the 100% of the acres ⇒ The 0.2% of the acres are 74 acres (in which there are old-growth trees).
Ok, sin = prep / hyp
so, perpendicular = 1 , and hypo = 4
so, base = sq. root ( 16-1 ) = root 15
and tan = prep / base = 1 / root (15)
