2 hours.
Step-by-step explanation:
Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9
= $297 but he wants to work a minimum of hours for a minimum of 270.
Thus we have the inequality:
252 + 9x ≤ 270
9x ≤ 18
x ≤ 2.
So the number of hours he must do clearing tables = 2.
Answer:
5) n * n * n * n * 6 * 6 * 6
6) 9 * 9 * x * x * x
7) 3 * 3 * 3 * y * y
Step-by-step explanation:
Answer:
x=vel of d
y=vel oh h
t1=time taken by d
t2=time taken by h
we have 4t1=5t2..............(1)
also
3xt1=4yt2....................(2)
comparing 1 and 2
x/y=16/15
