Step-by-step explanation:
Given : When students at Luray Middle School were surveyed, 22% said they would like hamburgers at lunch rather than hotdogs.
We know that to convert a percent into a fraction , we need to divide the percent by 100 , we get
Which can be written as :
Cancel out 2 from the numerator and the denominator , we get
Hence, 22% rounded to the nearest compatible fraction

Answer:
a) For this case we can use the fact that
And for this case since we ar einterested on and we know that the if we are below the y axis the sine would be negative then:
b) From definition we can use the fact that and we got this:
We can use the notabl angle and we know that :
Then we know that correspond to 225 degrees and that correspond to the III quadrant, and we know that the sine and cosine are negative on this quadrant. So then we have this:
Step-by-step explanation:
For this case we can use the notable angls given on the picture attached.
Part a
For this case we can use the fact that
And for this case since we ar einterested on and we know that the if we are below the y axis the sine would be negative then:
Part b
From definition we can use the fact that and we got this:
We can use the notabl angle and we know that :
