Answer:8 and 12
Step-by-step explanation: 8 is 4 less than 12 and 12 and 8 equals 20
Answer: 20 names from each grade
Step-by-step explanation:
The two answers it comes down to are between every student from all of her classes and 20 students from each grade, however since the poll wants to determine how many people across the entire student body would attend, pulling from just Miranda's classes would add a grade level bias to the dance and would not be entirely random. 20 students from each grade is completely unbiased and properly represents the entire student body.
<u>Answer: </u><em><u>h=80 is the final answer. *The answer must be have a positive sign.*</u></em>
Explanation:
<em><u>Switch sides of an equation.</u></em>
<em><u>3/4h=60</u></em>
<em><u>multiply by 4 both sides of an equation.</u></em>
<em><u>4*3/4h=60*4</u></em>
<em><u>simplify.</u></em>
<em><u>3h=240</u></em>
<em><u>divide by 3 both sides of an equation.</u></em>
<em><u>3h/3=240/3</u></em>
<em><u>simplify.</u></em>
<em><u>240/3=80</u></em>
<em><u>80*3=240</u></em>
<em><u>3*80=240</u></em>
<em><u>240/80=3</u></em>
<em><u>h=80</u></em>
<em><u>Hope this helps!</u></em>
<em><u>Thanks!</u></em>
<em><u>Have a great day!</u></em>
Cosine 65 = 12 / x

So, I'd say you are correct.
Hello!
The answer is 20/60 simplest form is 1/3
To get 20/60 you must multiply the Numerator by Numerator (4*5) and Denominator by Denominator (5*12). Your answer will be 20/60.
To get 1/3 you must simplify a number that can go into 20 and 60 (which is 10). Divide 20/10 and 60/10 and get 2/6. Simplify 2/6 by 2 and get 1/3.
