Answer:
90minutes
Step-by-step explanation:
Let the time taken for passengers to be checked-in be t
Let the number of staff working be w;.
If the time taken for passengers to be checked-in for a flight is inversely proportional to the number of staff working then;
t = kw
when t = 30, w = 5
30 = 5k
k = 30/5
k = 6
to get t when w = 15
t = kw
t = 6(15)
t = 90minutes
Hence it will take 90minutes long
Answer:
1.6
Step-by-step explanation:
Lets count how many points are x and y away from each other since we dont have a graph.
X and Y points:
35-15=20
56-24=32
Use the formula:
32/20 = 1.6
Answer:
3
Step-by-step explanation:
Answer:
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
Step-by-step explanation:
We are told she would like to have at least 40 cupcakes and cookies combined.
If a is number of cupcakes and b is number of cookies, then this inequality is;
a + b ≥ 40
Secondly, we are told she would like to have at most 5 more cupcakes than cookies.
Thus, the inequality is;
a + 5 ≤ b
Lastly, we are told that cupcakes sell for $2.50 and cookies for $1.50
Thus, the inequality is;
2.50a + 1.50b ≤ 105
Finally, the 3 inequalities are;
a + b ≥ 40
a + 5 ≤ b
2.50a + 1.50b ≤ 105
