Answer:
Assuming each class is filled to capacity, the average class size is 70.
Step-by-step explanation:
We have to find the weighted average of the number of students.
The weights are the number of classes.
We have that:
One class of 20 students
Eight classes of 60 students.
One class of 80 students.
Four classes of 100 students.
So
Assuming each class is filled to capacity, the average class size is 70.
Answer:
Option B
Step-by-step explanation:
Speed is distance moved per unit tine and is expressed as s=d/t
Making d the subject then
d=st
Where d is distance, s is speed and t is time taken in time.
Conversion
1 hour has 60 minutes hence 45 mins converted to hours will be 45/60=0.75
Substituting 0.75 hours for t and 170 mph for s then
d=0.75*170=127.5 miles due North
However, tge plane had initially moved 12.5 miles hence the relative distance due North will be 127.5-12.5=115 miles due North
Answer:
π·6^2
Step-by-step explanation:
Profit = revenue - expenses
12000 = 12x - (7.50x + 10,000)
12,000 = 12x - 7.50x - 10,000
12,000 + 10,000 = 4.5x
22,000 = 4.5x
22,000 / 4.5 = x
4888.88 rounds to 4889 = x......4889 baseballs
