If they are growing 80% for every twodays, it would be 40% for every one day.
Bacteria after 9 days = 212 * 9 * 40 / 100
= 763.2
To round up, the population of bacteria after 9 days would be 763, with a growth rate of 80% for every two days.
Answer:
Edger needs 15 cookies and 5 brownies.
Step-By-Step:
6 + 6 + 3 = 15
2 + 2 + 1 = 5
4 can go into 10, 2.5 times
Answer:
m∠ACD = 40°
Step-by-step explanation:
(4x + 2) + (6x - 12) = 8x,
10x - 10 = 8x,
2x = 10,
x = 5
8(5) = 40°
Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:

Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that
is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find
:

This is given in radians, so
is 4 radians
D is the correct answer choice.
