Answer:

Letter D is the correct answer.

Step-by-step explanation:

In the graph, the first line is an increasing diagonal and it stops in 10, meaning that John travelled 10 miles in 10 minutes.

After that, there is a horizontal line that indicates how much time he spent at the restaurant.

Finally, the last diagonal shows the distance travelled (5 miles) and the time it took (10 minutes.)

Security A rounds every 2 minutes and 20 seconds in the gate 1. Security B
JulsSmile [24]

Answer:

They will do rounds together again in 11 minutes and 40 seconds.

Step-by-step explanation:

Security A rounds every 2 minutes and 20 seconds in the gate 1.

That is, after 2*60 + 20 = 120 + 20 = 140 seconds.

Security B rounds every 1 minute and 40 seconds in the gate 2.

That is, after 1*60 + 40 = 60 + 40 = 100 seconds.

After how many minutes they will rounds together again?

First, we find this is seconds, which is the least common multiple between 140 and 100. Factoring them by prime factors:

140 - 100|2

70 - 50|2

35 - 25|5

7 - 5|5

7 - 1|7

1 - 1

lcm(140,100) = 2*2*5*5*7 = 700 seconds

They will do rounds together again in 700 seconds, which is 11 minutes and 40 seconds.

Answer:

\frac{ {11}^{56} }{ {5}^{18} }

Step-by-step explanation:

{55}^{56}  \times  {5}^{22}  \times  {5}^{ - 96}

=  {55}^{56}  \times  {5}^{ - 74}

=  {11}^{56}  \times  {5}^{56}  \times  \frac{1}{ {5}^{74} }

=  {11}^{56}  \times  \frac{1}{ {5}^{18} }

=  \frac{ {11}^{56} }{ {5}^{18} }
