5h + 9 = 10h + 6 - 5h + 3
20 + 1.5 = 21.5
- 2 = 19.5
so hourly he gets paid $19.50
Answer:
6 ounces of water
Step-by-step explanation:
In this question, we are asked to calculate the amount in ounce that would be added to the recipe.
From the question, we can see that the recipe requires 3/4 cups of water.
From the question also, we can also see that one cup equals 8 ounces.
Now to know the amount of water that is to be added, what we need to do is to simply multiply the fraction of water in the recipe by 8 ounces
This is equal to 3/4 * 8 = 6 ounces
Hence, she needs to add a total of 6 ounces of water to the recipe
Given that there were 30 bacteria present originally.
a=30
Also given that the number doubles every one hour.
After one hour the count =2×30=60
Since the count doubles every hour it forms a G.P. with r=2
a,ar,ar2........
The count at the end of 2nd hour=ar^2=30×2^2=120
The count at the end of 4th hour=ar^4=30×2^4=480
The count at the end of 8th hour=ar^8n=30×2^8=7680
etc.
The count at the end of n^th hour=ar^n=30×2^n
Also, the equation y=30*(2)^8/1 give the same result y= 7680
