Your baby brother has an ear infection. The doctor said there are probably 50,000 bacteria in his left ear. The penicillin the d
octor prescribed will kill 7% of the bacteria every hour. About how long will it take for there to be less than 25,000 bacteria?

Answer:
Step-by-step explanation:
-The volume of a cone is given by the formula:
Where:
- r is the cone's radius.
- h is the cone's height.
#We substitute for r and h in the formula to solve for V:
Hence, the each cone's volume is
The length of GE is 10 units
Explanation:
Given that the length of XY = 5 units and YZ = 4.6 units
<u>The length of GE:</u>
We need to determine the length of GE
From the figure, we can see that ZY bisects GE and XY bisects EF.
The lines ZY and XY both bisect GF.
The midpoint theorem states that "the line segment connecting the midpoints of two sides of a triangle is parallel to the third side and is congruent to one half of the third side".
Since, we have,
EX = XF and X is the midpoint of EF
GY = YF and Y is the midpoint of GF
Since, XY is the line segment that connects the midpoints of the two sides of the triangle.
Applying the midpoint theorem, we have,
Thus, the length of GE is 10 units.
