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
Answer:
18 miles per gallon
90/5=18
Step-by-step explanation:
Answer:
875
Step-by-step explanation:
lets assume the original amount X
the new amount = X - ( X × 40% )
525 = (60 × X) ÷ 100
X = ( 525 × 100 ) ÷ 60
<u>X = 875</u>
7+14g because your multiplying seven by the parenthesis and because you don’t know the value of g you have to keep it as 2g times 7 which would be 14g
