You decided to gather some information for how many days it rained over a period of time. You observed that it rained on 17 days
1 answer:
The correct answer is 17: 30
Explanation:
The purpose of a ratio is to express the relationship between two elements in terms of quantities. For example, if there are 5 oranges and 4 lemons the ratio is 5 to 4. Additionally, this relationship between the quantities of two different things can be expressed as a fraction, by using a colon (:) or by using the word "to." In the last two cases, the colon or word "to" separate the two amounts compared.
In the case presented, the total of days observed was 30 days (17 days with rain + 13 days with no rain) and the ratio of rainy days to the total of days can be expressed as 17:30, or as 17 to 30, considering there were 17 rainy days out of a total of 30 days.

Sine and cosine are co-function complements which means that value of sine of an angle is equal to the value of cosine of the complementary angles.
This can be represented by:
Given statement:
Applying co-function complements
Since, we can represent 70° = 90°-20°
So
Thus, makes the statement true.
