Answer: There were 525 pine trees.
Step-by-step explanation:
Given: Total trees = 1250
Percentage of oak trees = 32%
Percentage of birch trees = 26%
Since remaining trees are pine trees.
Percentage of pine trees = 100% - 32% - 26%
=42%
The number of pine trees = 42% of 1250
= 0.42 ×1250
= 525
Hence, there were 525 pine trees.
Answer:
449.65
391x.15=58.65
$58.65+$391= 449.65
The second one and the fourth one :)
LCM(2x² , 3y) = 6x²y
these two expressions 2x²and 3y have no common factor
Then
LCM(2x² , 3y) = 2x² × 3y
= (2×3)x²y
= 6x²y
y=11.142857
Simplify 5.2/3.5 to 1.485714
1.485714=y/7.5
Multiply both sides by 7.5
1.485714× 7.5=y
Simplify 1.485714×7.5 to 11.142857
11.142857=y
Switch sides
