Answer:
A building is 35 feet tall
35
The scuba diver is 35 feet below sea level
-35
The basement is 7.6 feet below ground
-7.6
Oliver owes his sister $23
-23
Erika jumped 2.3 feet above the ground
2.3
Step-by-step explanation:
You have to look at the word choice, like below or tall. If they are describing something below something else they generally want it to be negative, or if they are talking about how much you owe. Otherwise it will be positive. Then just match the numbers.
You basically just have to do . . .
257/54
4.759 . . .
≈ 4.76 hours
Answer: 4.76 hours
The formula for that area would be A=1/2xbxh so you would do A=1/2x3.5x3 and that equals 5.25
Correct question:
Jada walks up to a tank that can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water. At what rate is the amount of water in the tank changing? use a signed number, and include the unit of measurement in your answer.
Answer: - 2/3
Step-by-step explanation:
Given the following :
Amount of gallon tank can hold = 10
tank drains at a constant rate :
First look tank contains 7 gallons
After 3 minute,
Tank contains 5 gallons
Thus signifies a 2 gallon decrease in volume of water after 3 minutes
Therefore, the rate of change =( change in volume) / time
Rate of change = (final volume - initial volume ) / 3
(5 - 7)/ 3 = - 2/3
