Answer:
C. 2
Step-by-step explanation:
If the discriminant is >0 we have 2 real solutions
If the discriminant is =0 we have 1 real solutions
If the discriminant is <0 we have 2 complex solutions (no real solutions)
since 10>0 we have 2 real solutions
1) (576*3/128) minutes
2) 81 men, 19 women. Total 100. 81/100 men. With 250 members, (250*81/100) men
3) (240*7/3) books in total

I believe that answer is C
What percent of $68.73 is $12? We can find out what we have to multiply to $68.73 to get $12. We can substitute this with "x". So then, our equation becomes 68.73x = 12. From there, you just do basic algebra.
You should get <span>17.4596246% which can then be rounded down to 17% depending on which place you're rounding it by.</span>
That's the exact answer; they usually want a calculator approximation at this point,
