438 has a three in the tens place :)
Answer:
100, because 180 - 50 - 90 = 40
The vertical angles theorem is applied, so now angle DCE is 40
And since CE = ED, its isosceles triangle, so base angles are equal, so 40 and 40.
180 - 80 = 100 = Angle E.
Yes. You did it right. Most of the angles are corresponding, and once you found the measure of x, you could use the corresponding angles postulate.
Hello!

Answer:
6866, 71995
Step-by-step explanation:
I'm going to assume it has a growth rate of 160% per hour.
Anyways, since after four hours, there were 45,000 Bacteria X in the egg salad, we can write the following function:
, where P represents the initial amount, B(h) represents the total, and h represents the number of hours that has passed. The 1.6 represents the 160% growth rate per hour.
We already know that four hours has passed when the population is 45,000, thus:
So the initial population is around 6866.
After five hours, the number of bacteria will be:
