Answer:
59 bacteria would there be after 4 hours.
Step-by-step explanation:
Given:
Bacteria in the petri dish = 40
Time taken for the bacteria to be doubled =17 hours
To Find:
To Find the number bacteria left after 4 hours = ?
Solution:
By using the proportionality,
After 17 hours the number of bacteria will be 80.
Let the number of bacteria after 4 hours be x
then
Now by cross multiplication
x= 18. 82
So the number of bacteria after 4 hours will be
= 40 + 18.82
= 58.82
=59
Answer:
$5 and $3
Step-by-step explanation:
Cost of banana split = b
Cost of hot fudge sundae = s
<u>From the first equation we get: </u>
<u>Replacing in the second equation:</u>
- 4(11 - 2s) + 3s = 29
- 44 - 8s + 3s = 29
- 44 - 29 = 5s
- 15 = 5s
- s = 15/5
- s = 3
Then
- b = 11 - 2*3 = 11 - 6 = 5
So banana split costs $5 and hot fudge sundae costs $3
slope = 2 and y-intercept = 0
the equation of a line in ' slope- intercept form ' is
y = mx + c ( mis the slope and c the y-intercept )
given 2x - y = 0 ( add y to both sides )
2x = y or y = 2x + 0 ← in slope-intercept form
with slope m = 2 and y-intercept c = 0
