Hope this helps!
It would be: 31/2 / 3/4
we can write it as 31/2 * 4/3 = 62/3
So, your answer is 62/3
Answer:
LCM = 117
Step-by-step explanation:1. Find the prime factorization of 9. 9 = 3 x 3 2. find the prime factorization of 13. 13 = 13 3. Multiply each factor the greater number of times it occurs in steps 1) or 2) above to find the lcm: 3 x 3 x 13 = 117. Hope it helped.
Answer:
- c(n) = 320·0.96^n
- 28 years
Step-by-step explanation:
Each year, the class size is multiplied by 1 - 4% = 96% = 0.96. After n years, it has been multiplied by that number n times. Repeated multiplication is signified using an exponent.
Class size (c) can be modeled by ...
c(n) = 320·0.96^n
__
You want to find n such that c(n) = 100. Put in that value and solve.
100 = 320·0.96^n
100/320 = 0.96^n . . . . . . . divide by 320
log(100/320) = n·log(0.96) . . . . . . . take logs
log(100/320)/log(0.96) = n ≈ 28.4932
In about 28 years, the class will have 100 students.
