Two consecutive even positive integers have a product of 2,400. What is the smaller of the two numbers?
Flura [38]

Answer: <u>Option C; 48</u>

Explanation:

Let one number = x

Other number = x+2

According to question-

[x] [x+2] = 2400

x^{2} + 2x - 2400 = 0

Solving this equation, we get-

[x - 48] [x - 50 ] = 0

x = 48 or 50

Since 48 is the smaller number here, answer is option C

Select the correct the correct answer. The arrows indecate the direction of flow. Which place experiences monsoos?
enot [183]

Answer:

India experiences the monsoon season

Explanation:

From the picture, it can be seen that India experiences the monsoon season.

This is evident in that the southwestern summer monsoon is brought into a low-pressure area primarily as a result of great heat moving over the Thar Desert in places like Rajasthan and other nearby areas during summer.

This is illustrated in the picture as wind direction moves inwards at this period, making the moisture-rich wind blowing from the Indian Ocean moves to the low-pressure region, hitting the great Himalayas, and thereby leads to rainfall.

Jack was sick with a cold and fever. the doctor prescribed him erythromycin, an antibiotic. analyzing the process of translation
KatRina [158]

Answer:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore, humans or sick cells do not have the active site to which the drug binds.

Explanation:

This is because it is a selective antibiotic that, when entering the body, binds to the 50s subunit of bacterial ribosomes, thus causing the disruption of protein transcription of bacteria.

This drug does not stop the transcription of human proteins since bacteria and humans do not have the same ribosomes, therefore humans or host cells do not have the active site to which the drug binds.

Erythromycin falls into the macrolide family and is considered a drug that is bacteriostatic at low concentrations and bactericidal at very high concentrations.

The difference between these named terms is that one ends the life of the bacterium (bactericidal) and the other stops the bacterial metabolism preventing its possibility of increasing in number.
