Answer:
The rule could be an = 6*2^(n-1)
Step-by-step explanation:
If it is a geometric sequence
Fifth term a5 = a1 r^4 where a1 is the first term
a1 r^4 = 96
r^4 = 96/a1
2^4 = 16 and 96/16 = 6 so a1 could be 6
Check: 6*2^(5-1) = 6*2^4 = 96.
Assuming you mean flutes 5: clarinets 4: trumpets 3...
Question 1 Answer: There are <u>36 trumpets</u>
Question 1 Explanation: 60/5=12 (the amount it went up in ratio), then multiply 12 by each of the other ratios. If there are 60 flutes then there are 48 clarinets (4*12) and 36 trumpets (3*12). If you want to check work, you can then divide answer back by 12 and get the ratio again.
Assuming there are no other type of band instruments in Carver's band then...
Question 2 Answer:There are 50 flutes, <u>40 </u>clarinets, and 30 trumpets.
Question 2 Explanation: add the ratio then divide it by the number of band people (5+4+3=12: 120/12=10) this answer is then what you multiply for each ratio. So, flutes 5*10=50, clarinets 4*10=40, trumpets 3*10=30. 50+40+30=120. Therefore, if there are no other type of band instruments in Carver's band there are 40 people who play the clarinet (unless of course some are played by computers/robots or an amazing person can play multiple at a time.
Answer:
2.2
Step-by-step explanation:
2+0+1+4+4=11
count all of the numbers
11/5=2.2
The writing is confusing, but as I understand it 21 is about 20% of 104 (21x100/104). The same prosentage of 500 equals 100,96 and I would round it to 101 (the answer of the first equasion x 500/100).
I think it would be 4? cause then it would give you .25
