In a particular​ year, a total of 40 comma 285 students studied in two of the most popular host countries when traveling abroad.
klasskru [66]

Answer: 2nd most popular country =  15895 students

most popular country = 24390 students

Step-by-step explanation:

Total students: 40,285

2nd most popular country = x students

most popular country = x + 8,495 students

x + x + 8495 = 40285

2x + 8495 = 40285

2x = 40285 - 8495

2x = 31790

x = 15895

2nd most popular country = x = 15895 students

most popular country = x + 8,495 = 15895 + 8,495 = 24390 students

when the temperature is 68 F, the speed of sound in air is approximately 343 meters per second. Approximately how many kilometer
Digiron [165]

Hello!

Since we are given that the speed of sound in the air travels about 343 meters per second, we can multiply 343 meters per second by 5, and then we convert the meters to kilometers.

343 · 5 = 1715 meters per 5 seconds.

1000 meters are equal to 1 kilometer. So, we can divide 1715 by 1000 to convert meters to kilometers.

1715 / 1000 = 1.715

Therefore, the speed of sound in air is about 1.715 kilometers per 5 seconds.

A car passes a landmark traveling at a constant rate of 55 kilometers per hour. One hour later, a second car passes the same lan
yarga [219]
Recall your d = rt, distance = rate * time

one car is going at 55kph, at say hmmm "t" time
the second car zooms by at 75kph, an hour later, thus " t + 1 "

notice, overtaking the 1st car, simply means, the second car comes from behind approaches the first car from behind and "gets there", at that very second, both cars have travelled a distance, say "d"

if the first car travelled "d" kilometers
for the second car to "get there" has to had travelled "d" distance as well

\bf \begin{array}{lccclll}
&distance&rate&time\\
&-----&-----&-----\\
\textit{first car}&d&55&t\\
\textit{second car}&d&75&t+1
\end{array}
\\\\\\
\begin{cases}
d=55t\\
d=75(t+1)\\
-------\\
55t=75(t+1)
\end{cases}

solve for "t"

STatiana [176]

Answer:

C. 3 Pencils Per Bag

Step-by-step explanation:

The Greatest Common Factor is 16, meaning Sarah has 16 friends.

She needs to distribute the pencils and erasers evenly.

16 friends x 3 pencils per bag = 48 pencils in total.

16 friends x 5 erasers per bag = 80 erasers in total.
