To find the quotient that represents the rate of change in the airplane's altitude, we divide the change in altitude by the time it took to make the adjustment.
The change in altitude is 4,000 feet (since the pilot decided to fly 4,000 feet lower).
The time it took to make the adjustment is 3.5 minutes.
Therefore, the quotient that represents the rate of change in the airplane's altitude is 4000 feet / 3.5 minutes.
Calculating this quotient, we find that the rate of change in the airplane's altitude is approximately 1142.86 feet/minute to the nearest hundredth.
A pilot is flying an airplane. Due to strong winds, the pilot decides to fly 4,000 feet lower to avoid excessive turbulence. It takes the pilot 3.5 minutes to make this adjustment. Interpret the quotient to describe the rate of change in the plane’s altitude. Give your answer to the nearest hundredth, and remember the plane is descending.
The quotient the best represents the rate of change in the air plane's altitude is ____ feet/minute.

To find the change in the amount of water in gallons in 1 minute, we need to divide the amount of water removed in 5 minutes by 5.
The amount of water being removed in 5 minutes is 250 gallons.
Therefore, the change in the amount of water in 1 minute is 250 gallons / 5 minutes = 50 gallons.
Therefore, the correct answer is 1. 50 gallons.
The amount of water being removed in 5 minutes is 250 gallons.
Therefore, the change in the amount of water in 1 minute is 250 gallons / 5 minutes = 50 gallons.
Therefore, the correct answer is 1. 50 gallons.

To find the change in the amount of water in gallons in 1 minute, we can determine the rate at which water is being removed by dividing the amount of water removed in 5 minutes by 5.
The amount of water being removed in 5 minutes is 250 gallons.
Therefore, the rate of water removal is 250 gallons / 5 minutes = 50 gallons/minute.
Because the question is asking for the change in the amount of water in gallons in 1 minute, the correct answer is 1. 50 gallons.
The amount of water being removed in 5 minutes is 250 gallons.
Therefore, the rate of water removal is 250 gallons / 5 minutes = 50 gallons/minute.
Because the question is asking for the change in the amount of water in gallons in 1 minute, the correct answer is 1. 50 gallons.
negative or positive 50?
Apologies for the confusion. The change in the amount of water in gallons in 1 minute would be -50 gallons, as the pump removes water from the tank.
Use the order of operation to solve:
(-4) x (7/5) x (-3/4) / (7/15)
A) 9
B) -9
C) 147/75
D) -147/75
(-4) x (7/5) x (-3/4) / (7/15)
A) 9
B) -9
C) 147/75
D) -147/75
To solve this expression using the order of operations, we follow the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
First, let's simplify the expression inside the parentheses:
(-4) x (7/5) x (-3/4) / (7/15)
= (-28/5) x (-3/4) / (7/15)
Next, let's perform the multiplication:
= (28/5) x (3/4) / (7/15)
= (84/20) / (7/15)
Now, let's perform the division:
= (84/20) x (15/7)
= (12/5) x (15/7)
= 180/35
Finally, let's simplify the fraction:
= 36/7
The simplified expression is 36/7, which is not one of the given answer choices. Therefore, none of the provided answer choices is correct.
