21:50
50:7
75:21
50:21
Answer:
50:21
Step-by-step explanation:
150:63
Divide both by 3:
150/3 = 50
63/3 = 21
so 50:21 is the correct answer (last option)
(Note that the first option is WRONG bc it's reversing the order.)
b . two
c . one
d . zero
The correct answer is B.Two

Step-by-step explanation:
B. 3 to 20
C.1 to 5
D.3 to 5
Answer: The correct option is (D) 3 to 5.
Step-by-step explanation: Given that a youth ice hockey game has 3 periods that are each 20 minutes long. Colin plays 12 minutes each period.
We are to select the correct ratio that shows Colin's playing time compared to the total number of minutes of playing time possible.
Since there are three periods, so Colin's total playing time is given by
And each period is 20 minutes long, so total number of minutes playing time possible will be
Therefore, the ratio that shows Colin's playing time compared to the total number of minutes of playing time possible is given by
Thus, the required ratio is 3 to 5.
Option (D) is CORRECT.
Answer:
Step-by-step explanation:
We have the following expression:
In order to work in a better way this expression, let's call and and rewrite:
Now, we know . Let's apply it here:
Simplifying:
According these trigonometric identities, we have:
Then:
Writing again the actual values:
Finally:
