Answer: 110 in the presence of no antibiotic, 53 in the presence of an antibiotic
Step-by-step explanation:
So first we are told the growth rate of a bacteria culture is 15% and the number of bacteria in the culture is 24
So we find 15% of 24
15/100 x 24 = 18/5
So 18/5 bacteria is produced every hour, then for 24hours
18/5 x 24 = 86.4
The number of bacteria is already 24 as said
So altogether
86.4 + 24 = 110.4 approximately 110
Then, for the presence of antibiotic, the growth rate is 5%
So 5% of 24
5/100 x 24 = 6/5
So 6/5 bacteria is produced every hour
For 24hours
6/5 x 24 = 28.8
Initial culture = 24
Final culture = 24 + 38.8 = 52.8 approximately 53
Answer:
A. wind blowing from the south
D. Low air pressure
C. High humidity
Step-by-step explanation:
High humidity can cause the clouds to shower. When the humidity is reached to 100 percent the rain starts. For the raining system the air pressure should be low. The low air pressure often indicates the thunderstorm. Cloud are ready filled with water and when the air pressure is lowered the rain starts.
Answer:
B. 14 m sq.
Step-by-step explanation:
Area for a triangle
A = W times H times 1/2
4 times 7 = 28
28/2 = 14
The length of RP should be 3. Hope this helps
Rotation is a transformation where an object is rotated about a fixed point.
<h3>What is a transformation?</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
<em>Translation, reflection and rotation</em> are rigid transformations because they preserve the shape and size of the figure.
Rotation is a transformation where an object is rotated about a fixed point.
