Fofino [41]

Answer:

Raisins : Pretzels = 1 : 2

Almonds: Raisins = 3 : 1

Step-by-step explanation:

Given

Raisins = 2

Pretzels = 4

Almonds = 6

Solving (a):

Ratio of Raisins to Pretzels

Raisins : Pretzels = 2 : 4

Divide 2 and 4 by 2

Raisins : Pretzels = 2/2 : 4/2

Raisins : Pretzels = 1 : 2

Solving (b):

Ratio of Almonds to Raisins

Almonds: Raisins = 6 : 2

Divide 2 and 6 by 2

Almonds: Raisins = 6/2 : 2/2

Almonds: Raisins = 3 : 1

Solve equation for 0
ludmilkaskok [199]

Answer:

60° or 120°

Step-by-step explanation:

You can solve the equation by combining like terms across the equal sign and using inverse operations. Since there are two terms with cos²∅, you can combine them.

6cos²∅ + 3 = 4 + 2cos²∅         Subtract 2cos²∅

4cos²∅ + 3 = 4                         Subtract 3 from both sides

4cos²∅ = 1                                Divide by 4 on both sides

cos²∅ = 1/4                               Square root both sides

cos ∅ = ± 1/2

Solve by identifying which angles have a cosine value of 1/2 and -1/2. These angles are 60° and 120°
