The answer is D Cause the amount of money they make per car plus the amount of money they make from tips times the amount of cars they wash and add them together should give you how much total money they made.
<u><em>Answer:</em></u>
<u><em>Explanation:</em></u>
<u>The given equation is:</u>
To get the value of B, we will need to isolate it on one side of the equation
<u>This is done as follows:</u>
<u>1- Multiply both sides by to get rid of the fraction:</u>
<u>2- Add 25 to both sides of the equation:</u>
Based on the above:
Hope this helps :)
Consider the right triangle ABC with sides a, b, and c as shown in the figure.
Let
, and
.
, so angles A and B are complementary.
According to the definition of sine, and cosine:
, and
Answer: they are equal.
-2 7/12 ... decimal form -2.583 ... exact form -31/12
Answer:
w = π/2
Step-by-step explanation:
I used trig identities (double angle) to solve this problem.
Step 1: Rearrange problem
2cos²(w) - cos(w) - 1 = 0
2cos²(w) - 1 - cos(w) = 0
Step 2: Trig Identity
cos2w - cos(w) = 0
Step 3: Combine like terms
cosw = 0
Step 4: Solve
w = cos^-1(0)
w = π/2
I may have done it wrong so don't rely too much on me
