Answer:
0
Step-by-step explanation:
Solution for cosx=-3/2 equation:
cos((3*pi)/5)*cos((3*pi)/20) = 0
(60*x^3)/(60*x^5) = 0
cos((3*pi)/5)*cos((3*pi)/20) = 0
cos((3*x)/5)*cos((3*x)/20) = 0
1.5/100 = 0
No. It means that you should find a integer to divide 32 47 80 , and the equals must be integer also. But the 3 numbers have no common factor
Answer: 540
Step-by-step explanation:
Given: A polling company reported that 53% of 1018 surveyed adults said that rising gas prices are "quite annoying."
To find: The exact value of 53% of 1018.
[we divide a percentage by 100 to convert it into a fraction of decimal]

Hence, the 540 adults said that rising gas prices are "quite annoying."
Thus, the exact value = 540
