9 because 9x3=27 or 27/3=9
Answer:
after 60 seconds = 1 minute ,they will together for the first time.
Step-by-step explanation:
Three bells toll at an interval of 4,5 and 6 second.
They will ring together at the time which will be the multiple of all the three time interval (i.e 4,5,6)
4 = 2*2
5= 5*1
6 = 2*3
LCM of these three number will be multiple of highest power of each prime number
highest power of 2 in the above problem 2^2
3 = 3
5 = 5
Thus, LCM 2^2 * 3*5 = 60
Thus, after 60 seconds they will together for the first time.
Then they will toll together after each interval of 60 seconds together.
Bookworm:
y = 14x
Star Readers:
y = 80 + 8x
IF you want to see when you pay the same amount, then we set up a system of equations:
14x = 80 + 8x
6x = 80
x = 40/3, so when you buy 13 or less books is the Bookworm bookstore better. Star Readers is better when you have 14 or more books.
I think answer should be what the other person said okay thanks have a great day
Given:initial investment = $60.increase in value by 15% each year
The function that best represents the above problem is: f(x) = 60 * (1.15)^x
f(4) = 60 * (1.15)⁴ = 60 * 1.75 = 105.00f(6) = 60 * (1.15)⁶ = 60 * 2.31 = 138.60f(7.86) = 60 * (1.15)⁷.⁸⁶ = 60 * 3 = 180After 7.86 years the value of the investment will be 3 times the initial valuef(8) = 60 * (1.15)⁸ = 60 * 3.06 = 183.60 After 8 years the value of the investment will be $184.00
