Answer: Benjamin's heart beats 85 times in 60 seconds.
Step-by-step explanation: For this problem we will be writing a ratio.
The ratio 17:12 represents this situation because the ratio states that Benjamin's heartbeat beats 17 times in 12 seconds. We want to know how many times his heart beats in 60 seconds.
Simply keep adding 17 to the left side of the ratio and 12 to the right side.
17:12
34:24
51:36
68:48
85:60
So, in 60 seconds Benjamin's heart will beat 85 times.

Answer:
200 students are neither in the band nor on any sports team
Step-by-step explanation:
To solve this problem we first have to calculate the students who play in the band and those who do sports
To calculate the students who play in the band we have to calculate 30% of the total number of students
30% = 30/100
400 * 30/100 = 120
120 students play in the band
To calculate the students who do sport we have to multiply 1/5 by the total number of students
400 * 1/5 = 80
Now we have to subtract from the total the amount that they do sports or play in the band
(400 - 80) - 120 = 200
This means that 200 students are neither in the band nor on any sports team
