A mountain goat is climbing to the top of a large cliff. The cliff is 50 feet higher than its starting point. If it takes the goat 22 minutes to climb this cliff, interpret the quotient to describe the rate of change in the goat’s elevation. Give your answer to the nearest hundredth.
To find the rate of change in the goat's elevation, we need to divide the change in elevation by the time taken. The change in elevation is given as 50 feet, and the time taken is given as 22 minutes.
So, the rate of change in the goat's elevation is 50 feet / 22 minutes = 2.27 feet per minute (rounded to the nearest hundredth).
A bird is flying at an average altitude of 10 meters above the ground. After 3 seconds, it settles on a branch that is 3 meters above the ground. Interpret the quotient to describe the rate of change in the bird’s altitude. Give your answer to the nearest hundredth and remember that the bird is descending.
To find the rate of change in the bird's altitude, we need to divide the change in altitude by the time taken. The change in altitude is given as 10 meters (initial altitude) - 3 meters (final altitude) = 7 meters (descending).
The time taken is given as 3 seconds.
So, the rate of change in the bird's altitude is 7 meters / 3 seconds = 2.33 meters per second (rounded to the nearest hundredth).
That is incorrect
Apologies for the incorrect response. Let's recalculate the rate of change in the bird's altitude.
The initial altitude is 10 meters above the ground, and the final altitude is 3 meters above the ground. Since the bird is descending, the change in altitude would be negative: 10 meters - 3 meters = -7 meters.
The time taken is given as 3 seconds.
So, the rate of change in the bird's altitude is -7 meters / 3 seconds = -2.33 meters per second (rounded to the nearest hundredth).
That is correct
Thank you for confirming. I'm glad the corrected response is accurate. If you have any more questions, feel free to ask.
A whale is swimming at a current depth of 15 meters below the surface. It swims up toward the surface and arrives there 9.5 seconds later. Find the quotient that best describes the rate of change in the whale’s depth. Give your answer to the nearest hundredth.
To find the rate of change in the whale's depth, we need to divide the change in depth by the time taken. The initial depth is 15 meters below the surface, and the final depth is at the surface (0 meters).
The time taken is given as 9.5 seconds.
So, the change in depth is 15 meters - 0 meters = 15 meters (ascending).
The rate of change in the whale's depth is 15 meters / 9.5 seconds = 1.58 meters per second (rounded to the nearest hundredth).
A restaurant uses a 15-pound bag of flour in 4 days. Each day, the bag of flour gets lighter as more flour is used. How much does the average amount of flour in the bag change each day? (Round to the nearest hundredth.)
To find the average amount of flour the bag changes each day, we need to divide the total change in flour by the number of days. The total change in flour is 15 pounds (initial amount) - 0 pounds (final amount) = 15 pounds.
The number of days is given as 4.
So, the average amount of flour the bag changes each day is 15 pounds / 4 days = 3.75 pounds (rounded to the nearest hundredth).
That is incorrect. The answer should be negative.
Apologies for the incorrect response. Let's recalculate the average amount of flour the bag changes each day, taking into account that the bag gets lighter.
The initial amount of flour is 15 pounds, and the final amount is 0 pounds as the bag gets fully used.
The total change in flour is 15 pounds - 0 pounds = 15 pounds.
The number of days is given as 4.
So, the average amount of flour the bag changes each day is -15 pounds / 4 days = -3.75 pounds (rounded to the nearest hundredth).
My apologies for the confusion caused earlier. Thank you for pointing out the error.
A squirrel has stored its acorns in a hole that is 45 feet from the ground in a tall tree. The squirrel starts on a perch 100 feet above the ground. The squirrel moves from the perch down to its stored acorns in 5.25 seconds. Interpret the quotient to describe the rate of change in the squirrel’s height above the ground. Give your answer to the nearest hundredth.
To find the rate of change in the squirrel's height above the ground, we need to divide the change in height by the time taken. The initial height is 100 feet above the ground, and the final height is 45 feet above the ground.
The change in height is 100 feet - 45 feet = 55 feet (descending).
The time taken is given as 5.25 seconds.
So, the rate of change in the squirrel's height above the ground is 55 feet / 5.25 seconds = 10.48 feet per second (rounded to the nearest hundredth).
Is the answer negative or no?
Apologies for the confusion. The answer is indeed negative since the squirrel is descending from a higher perch to a lower point. Let's recalculate with the appropriate sign.
The initial height is 100 feet above the ground, and the final height is 45 feet above the ground. The change in height would therefore be negative: 100 feet - 45 feet = -55 feet.
The time taken is given as 5.25 seconds.
So, the rate of change in the squirrel's height above the ground is -55 feet / 5.25 seconds = -10.48 feet per second (rounded to the nearest hundredth).
Thank you for pointing out the need to include the sign.
A dolphin jumped above the surface of the water. It reached an altitude of 3.5 meters above the surface of the water and then dove 10 meters below the surface of the water. It went from its highest point above the water to its lowest depth in 12.5 seconds. Interpret the quotient to describe the average rate of change in the dolphin’s position. Give your answer to the nearest hundredth.
To find the average rate of change in the dolphin's position, we need to divide the total change in position by the time taken. The initial position is 3.5 meters above the water, and the final position is 10 meters below the water.
The change in position is 3.5 meters (above) + 10 meters (below) = 13.5 meters (descending).
The time taken is given as 12.5 seconds.
So, the average rate of change in the dolphin's position is 13.5 meters / 12.5 seconds = 1.08 meters per second (rounded to the nearest hundredth).
Note that a negative sign is not used in this case since the question asks for the average rate of change, which considers both ascending and descending movements.
A scuba diver was at a depth of 15 meters below the surface when she saw something interesting about 10 meters lower. She made the descent in 10.1 seconds. Interpret the quotient to describe the rate of change in the diver’s depth. Give your answer to the nearest hundredth.
To find the rate of change in the diver's depth, we need to divide the change in depth by the time taken. The initial depth is 15 meters below the surface, and the final depth is 10 meters lower than the initial depth (15 meters - 10 meters = 5 meters below the surface).
The change in depth is 5 meters (descending).
The time taken is given as 10.1 seconds.
So, the rate of change in the diver's depth is 5 meters / 10.1 seconds = 0.50 meters per second (rounded to the nearest hundredth).
It is recommended that hikers drink 24 ounces of water an hour. If a canteen has 24 ounces of water, how much should the amount of water in the canteen change every 10 minutes?
To determine how much the amount of water in the canteen should change every 10 minutes, we need to calculate the fraction of an hour that 10 minutes represents.
There are 60 minutes in an hour, so 10 minutes is 10/60 or 1/6 of an hour.
The recommended amount of water is 24 ounces per hour.
To find the amount of water that should be consumed every 10 minutes, we divide the recommended amount by the fraction of an hour:
24 ounces per hour / (1/6 hour) = 24 ounces per hour * 6 = 144 ounces per hour.
Therefore, the amount of water in the canteen should decrease by 144 ounces every 10 minutes.
This is incorrect.
The options are:
A) 0.4 ounces
B) 4 ounces
C) −4 ounces
D) −0.4 ounces
Apologies for the previous incorrect response. Let's recalculate to find the correct answer.
If hikers are recommended to drink 24 ounces of water per hour, we need to determine the amount of water that should be consumed every 10 minutes.
To convert 10 minutes to hours, we divide by 60: 10 minutes / 60 = 1/6 hour.
To find the amount of water that should be consumed every 10 minutes, we multiply the recommended amount by the fraction of an hour:
24 ounces per hour * (1/6 hour) = 4 ounces.
Therefore, the amount of water in the canteen should decrease by 4 ounces every 10 minutes.
The correct answer is B) 4 ounces.
Wouldn't it be negative because you're taking away water?
Apologies for the oversight. You are correct. Since we are talking about removing water from the canteen, the amount should be negative.
Therefore, the correct answer is C) −4 ounces. The amount of water in the canteen should decrease by 4 ounces every 10 minutes, indicated by the negative sign.
