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.(1 point)
The quotient that best represents the rate of change in the whale’s depth is______meters/second.
To find the rate of change in the whale's depth, we can calculate the difference in depth and divide it by the time taken.
Depth difference = 0 meters - (-15 meters) = 15 meters
Time taken = 9.5 seconds
Rate of change in depth = Depth difference / Time taken
Rate of change in depth = 15 meters / 9.5 seconds ≈ 1.58 meters/second
The quotient that best represents the rate of change in the whale's depth is 1.58 meters/second.
Solve using division of rational numbers. If a car’s value decreases by $2,500 in the first 6 months, how much does the value decrease per month? (Round to the nearest hundredth.) (1 point)
To find the value decrease per month, we divide the total value decrease by the number of months.
Value decrease = $2,500
Number of months = 6
Value decrease per month = Value decrease / Number of months
Value decrease per month = $2,500 / 6 ≈ $416.67
The value decreases by approximately $416.67 per month.
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.)(1 point)
To find the average amount of flour the bag changes each day, we divide the total amount of flour used by the number of days.
Amount of flour used = 15 pounds
Number of days = 4
Average amount of flour change per day = Amount of flour used / Number of days
Average amount of flour change per day = 15 pounds / 4 ≈ 3.75 pounds
The average amount of flour in the bag changes by approximately 3.75 pounds each day.
Wrong
Apologies for the mistake. Let's recalculate.
The average amount of flour in the bag changes each day can be found by dividing the total amount of flour used by the number of days.
Amount of flour used = 15 pounds
Number of days = 4
Average amount of flour change per day = Amount of flour used / Number of days
Average amount of flour change per day = 15 pounds / 4 days = 3.75 pounds/day
Therefore, the average amount of flour in the bag changes by 3.75 pounds per day.

To find the value decrease per month, we divide the total value decrease by the number of months.
Value decrease = $4,000
Number of months = 12
Value decrease per month = Value decrease / Number of months
Value decrease per month = $4,000 / 12 ≈ -$333.33
The value of the car decreases by approximately -$333.33 per month.
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?(1 point)
Responses
4 ounces
4 ounces
−0.4 ounces
negative 0.4 ounces
0.4 ounces
0.4 ounces
−4 ounces
To find the amount of water that should change in the canteen every 10 minutes, we need to find the proportion of the recommended water intake.
Recommended water intake per hour = 24 ounces
Recommended water intake per minute = 24 ounces / 60 minutes = 0.4 ounces
Therefore, the amount of water in the canteen should change by 0.4 ounces every 10 minutes.
