Answer:
2.33*10^4
Step-by-step explanation:
Let's subtract the enrollment in 1900 from the enrollment in 1950.
2.7*10^4 - 3.7*10^3
= 27*10^3 - 3.7*10^3
= (27-3.7)*10^3
= 2.33*10^3
2.33*10^4 students.
The cost of packaging the box of chocolates per weight unit is; ¹/₄x²/(x + 2)
<h3>
</h3><h3>How to Solve Algebra problems?</h3>
We are given the cost of packing the box as;
C(x) = ¹/₄x²
where;
x is the number of chocolates
We are told that a box can never have fewer than 3 chocolates.
Now, the weight of a box of chocolates is given by; W(x) = x + 2
Thus, cost per unit weight is;
C(x)/W(x) = ¹/₄x²/(x + 2)

Answer:
A) 46 mph
Step-by-step explanation:
<em>Step 1: To find the speed, you need to find the distance and time to travel between Chicago and Cleveland.</em>
Distance = 354 miles
Time = 9: 50 am to 5: 30 pm
Time = 7 hours 40 minutes
<em>Step 2: Convert time to hours</em>
1 hour = 60 minutes
40 minutes = 60/40 = 2/3 hours
<em>Step 3: Find the speed</em>
Speed = Distance/Time
Speed = 354/7 + 2/3
Speed = 1062/23
Speed = 46.17 miles per hour rounded off to 46 mph
Therefore, A is the correct answer.
