Answer:
360∘
Step-by-step explanation:
(4−2) ⋅ 180 = 360
Correct answer is D.
During the first 150 miles, she drove 150 miles at a speed of x<span> miles per hour, so her time was
</span><span>
</span>where

<span>is the time she spent driving the first 150 miles.
</span>
On the second half of the trip, she drove at <span>1.25x</span> miles per hour. There, the equation would be

where

is the time she spent driving the second 150 miles.
Solve both of those equations for the t<span> variables, then add them together. Your answer will be
</span>

It's right
Answer:
0.03865
Step-by-step explanation:
Since the true density for the two types of trees are given, we would evaluate the average for both of them
Low percentage of juvenile wood density = 0.523 and 0.0543
Average density = 0.523 + 0.0543/2
Average density = 0.55015
Moderate percentage of juvenile wood density = 0.489 and 0.0450
Average density = 0.489 + 0.0450/2
Average density = 0.5115
Therefore, difference in true average density for the two woods are = 0.55015 - 0.51150
= 0.03865
