Answer:
I think it is the fourth one
Step-by-step explanation:
I hope that is useful for you :)
Angle 5 is 90 and because all the angles should add to 360 degrees, angle 4 is 20, and angles 3 and 6 are 70 and 70. 90+90+20+20+70+70= 360
Suppose that the population of NYC is 10,000,000, and there're average of 3 people per household
= 3.3 million HHs
and 1 in 10 HHs has a piano
= 330,000 pianos
on average, a piano is tuned once a year
= 330,000 tuning per year
= 6,000 tunings per week
suppose a piano tuner works 5 days a week and handling 5 pianos a day. That will be 25 pianos a week
hence, you need 6,000/25 = 240 tuners
hope this helps
$55. Multiply 15 by 20 to find out exactly how much he needs for 20 weeks, which is $300. subtract 245 from 300 to find out how much more money he needs to add to his account.
