Answer:
2100
Step-by-step explanation:
28.34 rounds to 30
We look at the 8 which is greater than 5 and rounds the 2 to 3
69.72 rounds to 70
We look at the 9 which is greater than 5 and rounds the 6 to 7
30*70

Step-by-step explanation:
Answer: Fish A: 9 inches ; Fish B: 6 inches
Step-by-step explanation:
This can be turned into a systems of equation, where x equals the length of fish A and y equals the length of fish B:
3x + 2y = 39 → -3x - 2y = -39
3x + 4y = 51 → 3x +4y = 51
Combine: 0 + 2y = 12 → y = 6 inches.
Plug back in: 3x + 2(6) = 39 → 3x = 27 → x = 9 inches.
Answer:
0.2 or 20%
Step-by-step explanation:
If the times of arrival vary uniformly, there is an equal chance of an employee reporting at any given time between 8:40 and 9:30.
The range between 8:40 and 9:30 is 50 minutes.
The range between 9:00 and 9:10 is 10 minutes.
Therefore, the probability that a randomly chosen employee reports to work between 9:00 and 9:10 is:

The probability is 0.2 or 20%.
500m:2km (change km to m)
500m:2000m (divide by 100)
5m:20m (divide by 5)
1m:4m
