Answer:
Step-by-step explanation:
<u>Given:</u>
- Initial amount of bacteria = 50000
- Growth rate = 2 times a day
<u>Required equation:</u>
<u>Solve for x:</u>
- 400000 = 50000*2^x
- 2^x = 400000/50000
- 2^x = 8
- 2^x = 2^3
- x = 3
After 3 days bacteria numbers will reach 400000
First you have to divide 165 by 3, which is 55. and then 55 multiplied by 8 is 440. so in 8 hours, they could travel 440 miles.
Answer:
that x is represented by 3 as the value
Step-by-step explanation:
Convert 10 ft to inches by multiplying it by 12. That’s 120 inches. Divide this number by 20 inches per strip to get 6 strips needed.
Answer:
[3x + (y/2)]
Step-by-step explanation:
English Translation
Suppose we have x confirmed cases of coronavirus and y suspected cases. A - If the confirmed cases triple and half of the suspects fall, we will have the following expression to represent the total number of cases:
Solution
Number of confirmed cases = x
Number of suspected cases = y
Number of confirmed cases triples and becomes 3x
Half of the suspected cases fall and becomes (y/2)
Total number of cases then becomes
[3x + (y/2)]
In Portugese/Em português
Número de casos confirmados = x
Número de casos suspeitos = y
O número de casos confirmados triplica e se torna 3x
Metade dos casos suspeitos cai e se torna (y / 2)
O número total de casos passa a ser
[3x + (y / 2)]
