Answer:
Least to greatest
0.623
5/8
65%
2/3
Step-by-step explanation:
Converting to %s
5/8 = 62.5%
0.623 = 62.3%
2/3 = 66.67%
First let's find the angles a and b.
We have then:
sin a = 4/5
a = Asin (4/5)
a = 53.13 degrees.
cos b = 5/13
b = Acos5 / 13
b = 67.38 degrees.
We now calculate cos (a + b). To do this, we replace the previously found values:
cos ((53.13) + (67.38)) = - 0.507688738
Answer:
-0.507688738
Note: there is another way to solve the problem using trigonometric identities.
Hello! And thank you for your question!
To get a improper fraction:
times the denominator by the whole number. Then add the numerator.
5*5=25+4=29.
Final Answer:
29/5
If they are 36 together, and Marsha is twice Mary then do 2x+x=36
Saying that Marsha is twice Mary.
