Answer:
28.57 m²
Step-by-step explanation:
Use rational terms.
Cross multiply:
7/9 · x = 1/9 · 200
7/9x = 200/9
x = 200/9 ÷ 7/9
x = 200/9 × 9/7
x = 200 · 9 / 9 · 7
x = 200 / 7
x = 28.57 m

Answer:
Option d
Step-by-step explanation:
We need 2 fundamental data to solve this problem.
1.- Average number of clients attended in 1 hour.
2.- Time in which it is expected that a client will be attended.
They tell us that the average number of clients served in an hour is m = 8
They tell us to calculate the probability that the client will be seen in less than 15 minutes.
But the time t in the formula is given in hours.
Therefore we must write 15 minutes according to hours.
We know that .
So:
.
Now we substitute in the formula and to find P.
Solution:
6 tickets = $42
1 ticket = $42 ÷ 6
= $7
Therefore,
Number of tickets = $77 ÷ $7
= 11 tickets
