Answer:
1 is allowed on the elevator.
2 is allowed on the elevator.
3 is allowed on the elevator.
4 is not allowed on the elevator.
5 is allowed on the elevator.
Step-by-step explanation:
If the maximum weight capacity of the elevator is 750 pounds, then that means every weight that is 750 pounds or less is allowed on the elevator.
1 is allowed because 700lbs is lower than 750lbs, therefore it is safe.
2 is allowed for the same reason, 620lbs is lower than 750lbs.
etc, etc.
So that's all you need to look for :)
Answer:
617 student tickets
Explanation:
Number of student tickets = x
Number of adult tickets = 920−x
Then
2⋅x+4⋅(920−x)=2446
2x+3680−4x=2446
−2x=2446−3680
−2x=−1234
x=617 tickets for students
920−617=303 tickets for adults
Answer:
100,000
Step-by-step explanation:
Investment ratio = 3 : 2
Rate = 5% and 4% simple interest
Total interest after 2 years = 9200
Let total investment = t
(3/5t * 0.05 * 2) + (2/5t * 0.04 * 2) = 9200
3/5t * 0.1 + 2/5t * 0.08 = 9200
0.06t + 0.032t = 9200
0.092t = 9200
t = 9200 / 0.092
t = 100,000
Answer:
A.) The red cylinder.
Step-by-step explanation:
For a cylinder:
V = (1/3)(pi)r^2h
Red:
V = (1/3)(pi)(2^2)(4) = 16pi/3
Blue:
V = (1/3)(pi)(1^1)(8) = 8pi/3
Since 16pi/3 is greater than 8pi/3, the red cylinder has a greater volume.
