Answer:
B. Associative Property of Addition
Step-by-step explanation:
-2(4w-1)=3(4w+2)
-8w+2=12w+6
-20w=4
w=-0.2
Answer:
Let x=sinθ
2sin²θ = 5sinθ - 3
2x²=5x-3
2x²-5x+3=0
(2x-3)(x-1)=0
2x-3=0 or x-1=0
x=3/2 or x=1
sinθ=2/3 or sinθ=1
θ=arcsin(2/3) or θ=arcsin(1)
θ=0.729727656 or θ=1.57079633=π/2
11 and 2/11 because 46 divided by 11 is 44 plus 2 is 46
Answer:
1750 trees
Step-by-step explanation:
Scale :
1 inch² = 1 mile²
Number of pine trees per square inch = 35
Area of model = 50 inch²
Hence,
Since scale factor is ; 1 inch² = 1 mile²
Area of forest will also be 50 mile²
Approximate number of trees on forest ;
Area * number of trees per square inch
50 * 35
= 1750 pine trees
