Answer:
85 tickets where sold
Step-by-step explanation:
Which equals 85 tickets
17.5 (Or 1/2) divided by 3 = 5.833333333, or just 5.8. So each piece would be 5 4/5 in long.
Sorry if it's a little confusing. Hope it helped! :)
tan 45 = 1 ===》 Sin 45 = √2 / 2
and also
tan 225 = 1 ===》Sin 225 = - √2 / 2
Sam can his job in 20 min. So he can do the whole job at the rate of 1 job in 20 minutes.
So he does 1/20 of the job per minute.
Rob can do the job in 30 min. His rate is 1/30 of the job per minute.
.
Working together how long does it take?
.
1/20*x + 1/30*x = 1 job done
, where x = minutes.
Multiply everything by 60 to get rid of the fractions.
3x + 2x = 60
5x = 60
.
Divide both sides by 12
x = 12
.
So the answer for working together it will take them 12 minutes.
