Y° = y₁° (opposite or Vertical angles), but y₁ = 45° corresponding angles,
then y = 45°
18 per adult, 9 per child total equals 2,475,00 and the hold of guest is 150
Answer:
a)
b) 334,858 bacteria
c) 4.67 hours
d) 2 hours
Step-by-step explanation:
a) Initial number of bacteria is the coefficient, that is, 250. And the growth rate is the coefficient besides “t”: 0.15. It’s rate of growth because of its positive sign; when it’s negative, it’s taken as rate of decay.
Another way to see that is the following:
Initial number of bacteria is N(0), which implies . And . The process is:
b) After 2 days means . So, we just replace and operate:
c)
d)
The length of the room is 156 sq in
This appears to be just an expression we are simplifying, not an equation we are solving. I THINK you are saying that the expression looks like this:
If you rationalize the denominator, you would get this expression:
which, after simplifying, looks like this:
and that's as simple as I can see that one getting. You can't factor anything out of the denominator to cancel with the numerator, so I think you're as simple as you can get there!
