To find the rate of change in the goat's elevation, we divide the change in elevation (50 feet) by the time taken (22 minutes).
Rate of change = change in elevation / time taken
= 50 feet / 22 minutes
To give the answer to the nearest hundredth, we divide 50 by 22 and round to the nearest hundredth:
Rate of change = 50 / 22 ≈ 2.27
The quotient that best represents the rate of change in the goat's elevation is 2.27 feet/minute.

-$ _____
hundredth.) (1 point)
-$ _____
To find out how much the car's value decreases per month, we divide the decrease in value ($2,500) by the number of months (6).
Value decrease per month = decrease in value / number of months
= $2,500 / 6
To give the answer to the nearest hundredth, we divide 2,500 by 6 and round to the nearest hundredth:
Value decrease per month = $2,500 / 6 ≈ -$416.67
The car's value decreases approximately by $416.67 per month. Note that the negative sign denotes a decrease in value.
Value decrease per month = decrease in value / number of months
= $2,500 / 6
To give the answer to the nearest hundredth, we divide 2,500 by 6 and round to the nearest hundredth:
Value decrease per month = $2,500 / 6 ≈ -$416.67

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)
____ pounds
____ pounds
To find the average amount of flour the bag changes each day, we divide the total change in the bag's weight (15 pounds) by the number of days (4).
Average change per day = total change / number of days
= 15 pounds / 4
To give the answer to the nearest hundredth, we divide 15 by 4 and round to the nearest hundredth:
Average change per day = 15 / 4 ≈ 3.75
Therefore, the average amount of flour in the bag changes by approximately 3.75 pounds each day.
Average change per day = total change / number of days
= 15 pounds / 4
To give the answer to the nearest hundredth, we divide 15 by 4 and round to the nearest hundredth:
Average change per day = 15 / 4 ≈ 3.75
Therefore, the average amount of flour in the bag changes by approximately 3.75 pounds each day.

Solve using division of rational numbers. if a car's value decreases by $4,000 in the first 12 months, how much does the value decrease per month? ( Round to the nearest hundredth.) ( 1 point)
Answer:
-0.003
0.003
$333.33
-$333.33
Answer:
-0.003
0.003
$333.33
-$333.33
To find out how much the car's value decreases per month, we divide the decrease in value ($4,000) by the number of months (12).
Value decrease per month = decrease in value / number of months
= $4,000 / 12
To give the answer to the nearest hundredth, we divide 4,000 by 12 and round to the nearest hundredth:
Value decrease per month = $4,000 / 12 ≈ -$333.33
Therefore, the car's value decreases by approximately $333.33 per month. Note that the negative sign denotes a decrease in value.
Value decrease per month = decrease in value / number of months
= $4,000 / 12
To give the answer to the nearest hundredth, we divide 4,000 by 12 and round to the nearest hundredth:
Value decrease per month = $4,000 / 12 ≈ -$333.33
Therefore, the car's value decreases by approximately $333.33 per month. Note that the negative sign denotes a decrease in value.
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)
4 ounces
0.4 ounces
-0.4 ounces
-4 ounces
4 ounces
0.4 ounces
-0.4 ounces
-4 ounces
To find out how much the amount of water in the canteen should change every 10 minutes, we divide the recommended amount of water per hour (24 ounces) by the number of 10-minute intervals in an hour (6, as there are 60 minutes in an hour divided by 10 minutes).
Change in water amount every 10 minutes = recommended amount per hour / number of intervals in an hour
= 24 ounces / 6 intervals
Change in water amount every 10 minutes = 4 ounces
Therefore, the amount of water in the canteen should decrease by 4 ounces every 10 minutes.
Change in water amount every 10 minutes = recommended amount per hour / number of intervals in an hour
= 24 ounces / 6 intervals
Change in water amount every 10 minutes = 4 ounces
Therefore, the amount of water in the canteen should decrease by 4 ounces every 10 minutes.
