Answer: 110 in the presence of no antibiotic, 53 in the presence of an antibiotic
Step-by-step explanation:
So first we are told the growth rate of a bacteria culture is 15% and the number of bacteria in the culture is 24
So we find 15% of 24
15/100 x 24 = 18/5
So 18/5 bacteria is produced every hour, then for 24hours
18/5 x 24 = 86.4
The number of bacteria is already 24 as said
So altogether
86.4 + 24 = 110.4 approximately 110
Then, for the presence of antibiotic, the growth rate is 5%
So 5% of 24
5/100 x 24 = 6/5
So 6/5 bacteria is produced every hour
For 24hours
6/5 x 24 = 28.8
Initial culture = 24
Final culture = 24 + 38.8 = 52.8 approximately 53
I think so yes because 10 is a whole number
Answer:
x = 147/5 and y = 78
Step-by-step explanation:
First solve by substitution and put 78 into y in -5x + 2y = 9 so you get 147/5
then plug 147/5 into x and find y
Answer:
Missing number is 1
Step-by-step explanation:
3(2x+1)
Using distributive property,
=>3(2x)+2(1)
=>6x+2
He pays $86.70 for the carpet. 8 time 10.2 equals 81.6.
10.2 divided by 2 equals 5.1. you will use 5.1 later.
81.6 + 5.1 = 86.7
