Answer:
5/7
Step-by-step explanation:
3-1 2/7
3=21/7 (by multiplying denominator)
1 2/7=16/7 (by multiply 1 and 7. Then add to 2)
21/7 - 16/7 = 5/7
Step-by-step explanation:
Time for equipment elevator = 11 seconds + 27 seconds = 38
Time for elevator for miners = 27 seconds
Speed of equipment Elevator = 7 feet/ sec
Speed of Miner elevator = 16 feet/ sec
Distance traveled by Equipment Elevator = Speed * time
= 7 * 38 = 266
Distance traveled by Miner Elevator = Speed * time
= 16 * 11 = 176
266 > 176
Therefore, The Equipment Elevator is deeper than the Miner Elevator
Depth of Equipment Elevator = 266m
Depth of Miner Elevator = 176m

This solution only needs proper understanding of the word problem and identification of variables.
Let x = number of hours rental of the canoe
It costs $5 per hour for a canoe. However, for every rental of one canoe, there is a deposit of $15 regardless.
The expression is then 5x + 15.
This expression will solve how much it costs in total to rent one canoe for x hours.
Divide both length and width by the dialtion factor and that will be the dimensions of the new rectangle. 2.5714in by 3.4286in. Round as needed
Answer:
(a) 13536.10J
(b) 27072.20J
Step-by-step explanation:
(a) Height of tank (h) = 4 feet = 4/3.2808 = 1.22m
Volume of water in full tank = 4ft×5ft×4ft = 80ft^3
Volume of water in half tank = 1/2 × 80ft^3 = 40ft^3
Density of water = 62.4lb/ft^3
Mass of water = density × volume = 62.4 × 40 = 2496lb = 2496×0.45359kg = 1132.16kg
Work done to empty half of the tank = mgh = 1132.16×9.8×1.22 = 13536.10J
(b) Work done to empty all of the tank = 2 × work done to empty half of the tank= 2 × 13536.10J = 27072.20J
