Answer:
D
Step-by-step explanation:
10/2 + 5.2/2 = 7.6
N = 75,000*(1/2)^(h/4) . . . . N = number alive; h = hours
3000 = 75000*(1/2)^(h/4) . . . . . substitute given numbers
1/25 = (1/2)^(h/4) . . . . . . . . . . . . . .divide by 75000
log(1/25) = (h/4)*log(1/2) . . . . . . . take the log, then divide by the coefficient of x
h = 4*log(1/25)/log(1/2) ≈ 18.6 . . . . hours
___
Of course log(1/25) = -log(25) = -2log(5), so the expression for h can be written as h = 8log(5)/log(2)
Alright so you have $24 dollars. 1/6 of 24 is 4 so now you have $20 dollars left. 2/3 of 20 is 13.333. So you subtract 13.333 from 20 to get a final anwser of 6.6666666667 dollars that roger saved. Hope i could help.
With questions like these, I like to use a system of operations my teacher told me.
First, we have to identify what the question is asking us to find. The question is asking us to find how many bouquets a florist makes per day (which is in one day).
Then, we have to find information that will help us answer the question. She makes 215 bouquets is 5 days.
Now, you put it together!
If she makes 215 bouquets in 5 days, and we need to find out how many she makes in 1 day, we need to divide 215 by 5!
215 / 5 = 43.
The florist makes 43 bouquets per day!
