If every over you climb 2 feet out, but then slip down 1, that means you technically only go up the well 1 ft/per hour. Then, if its 10 ft deep, then it would take you 10 hours.
Answer:
12^4/5
Step-by-step explanation:
When doing this you put the number the base is raised to on top of the fraction and the root number on the bottom
Based on the options given above, the answers that are true are: a correlation of r = .92 indicates a strong, positive correlation. a correlation of r = .01 means there is no significant correlation. a correlation of r = .01 means there is no significant correlation.
This statement is true. "Correlation is a numeric measure of the strength and the direction between two categorical variables."

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
Answer:
15.38 feets
Step-by-step explanation:
Using Pythagoras rule :
Sinθ = opposite / hypotenus
Sin 74 = h / 16
0.9612616 = h / 16
h = 0.9612616 * 16
h = 15.38 feets
