Answer:
20
Step-by-step explanation:
sin(28) sin(x)
---------- = -----------
7 5
sin(28)* 5 = 7sin(x)
---------------------------
7
sin(28) * 5
---------------- = sin(x)
7
You have to seperate sin from (x). When you do that, it becomes inverse (sin^-1).
sin(28) * 5
sin^-1 (------------------) = x
7
Imput that into you calculator, and you should get 19.59302173 (20 to the nearest degree)
Hope this helps.

Answer:
15 + 5w ≥ 75
Step-by-step explanation:
Let the number of weeks be represented as w.
We are told from the question that:
Charles is saving $5 each week from his allowance. He already saved $15 from the money he earned from mowing his neighbor's lawn.
The word "at least" in mathematics means equal to or greater than and it is represented by the sign ≥
Therefore, our inequality equation is written as:
15 + 5w ≥ 75
According to time, texting speed is a two-variable type of data that's represented by a scatterplot. This is because a scatterplot helps graph the data points, so that you can figure out and interpret the relationship.
The other answer is the sample response, so it's better to put it in your own words. :)
