Answer:
46.07
Step-by-step explanation:
CAH (cosine=adjacent/hypotenuse)
cos (71)=15 (adjacent)/x (hypotenuse)
x=15/cos(71)
x=46.07
Original is the whole = 5/5
After reduction is 2/5
2/5 =0.4 = 40%
Draw a rectangle.
Divide it in 5 parts
Shade 2 parts.
This is the new dimension 2/5 or 40%
Answer:
B. Combination: Number of ways = 15
Step-by-step explanation:
2 winners are to be chosen out of 6 people participating in the raffle drawing. In this case the order of selection does not matter, therefore, this situation involves combinations
So, we have to find combinations of 6 people taken 2 at a time. This can be represented by 6C2. The general formula for combinations is:

In this case n = 6 and r = 2. Using these values, we get:

Thus, there are 15 ways to chose the winners. So, option B gives the correct answer.
