Answer:
Equation:900/10=90
Each bag has 90 beads
90/10=9 9beads per chain
Step-by-step explanation:
Answer:
θ = 0°
θ = 30°
θ = 150°
θ = 180°
Step-by-step explanation:
2sin² θ = sin θ
Then
2sin² θ - sin θ = 0
Then
sin θ (2sin θ - 1) = 0
Then
sin θ = 0 or 2sin θ - 1 = 0
Then
sin θ = 0 or sin θ = 1/2
…………………………………………
We have sin θ = 0 and - 270° ≤ θ ≤180°
Then
θ = 0 or θ = π = 180°
On the other hand,
sin θ = 1/2 and - 270° ≤ θ ≤180°
Then
θ = π÷6 or θ = 5π÷6
π÷6 = 30° and 5π÷6 = 150°
Answer: y=0 and x=3
Step 1: Solve for x in 2x+9y=6.

(Subtract 9y from both sides)
( Divide both sides by 2)
Step 2: Replace x with 3-4.5y

Step 3: Solve for y
(By looking at this, we can determine that y=0)
Step 4: Replace y with 0

(Divide both sides 2)
Therefore, y=0 and x=3
