1+5(divided by)5
Since the problem asks to use PEMDAS, you divide 5 by 5 FIRST:
1+1
Then add:
2
Your answer is 2.
m∠3 = 180 - m∠8 = 180 - 123 = 57
m∠1 = m∠3 = 57°
Answer:
100
Step-by-step explanation:
160 * (5/8) = 100
Answer:

The doubling time is of 27.65 minutes.
Step-by-step explanation:
Exponential equation of growth:
The exponential equation for population growth is given by:

In which P(0) is the initial value and k is the growth rate.
A freshly inoculated bacterial culture of Streptococcus contains 100 cells.
This means that
. So

When the culture is checked 60 minutes later, it is determined that there are 450 cells present.
This means that
, and we use this to find k. So






So

Doubling time:
This is t for which P(t) = 2P(0) = 200. So






The doubling time is of 27.65 minutes.
Answer: Choice C) y = 30/x
Inverse variation equations are of the form y = k/x. In this case, k = 30. We can rearrange the format to get x*y = k after multiplying both sides by x. So y = 30/x can be turned into x*y = 30.
