A water tank decreases by 10 gallons every 3 hours every day. What is the total change in the amount of water in the tank after 6 days?(1 point)
Since the water tank decreases by 10 gallons every 3 hours and there are 24 hours in a day, the tank decreases by 10/3 = <<10/3=3.33>>3.33 gallons per day.
After 6 days, the total change in the amount of water in the tank is 6 * 3.33 = <<6*3.33=19.98>>19.98 gallons. Answer: \boxed{19.98}.
A water tank decreases by 10 gallons every 3 hours every day. What is the total change in the amount of water in the tank after 6 days?(1 point)
−80 gallons
negative 80 gallons
−480 gallons
negative 480 gallons
480 gallons
480 gallons
80 gallons
The water tank decreases by 10 gallons every 3 hours, so in 24 hours (1 day), it will decrease by 10 gallons every 24/3 = 8 times.
Therefore, in 1 day, the water tank will decrease by 8 * 10 = 80 gallons.
After 6 days, the total change in the amount of water in the tank will be 6 * 80 = 480 gallons.
So, the correct answer is 480 gallons. Answer: \boxed{480}.

Question
A recipe calls for 13 of a container of yogurt. Each container of yogurt has 150 calories. The recipe makes 4 servings. Which set of calculations would give the correct number of calories per serving?(1 point)
Responses
13×150÷14
Start Fraction 1 over 3 End Fraction times 150 divided by Start Fraction 1 over 4 End Fraction
13×150÷4
Start Fraction 1 over 3 End Fraction times 150 divided by 4
13÷150÷4
Start Fraction 1 over 3 End Fraction divided by 150 divided by 4
13×150×4
The correct set of calculations to find the number of calories per serving is: 13 × 150 ÷ 4.
This is because the recipe calls for 13 of a container of yogurt, which has 150 calories. Since there are 4 servings made from the recipe, we need to divide the total number of calories (13 × 150) by the number of servings (4) to find the number of calories per serving.
So, the correct set of calculations is 13 × 150 ÷ 4. Answer: \boxed{13 \times 150 \div 4}.
To find the total change in the amount of water in the tank after 6 days, we first need to calculate the change in the amount of water each day.
Since the water tank decreases by 10 gallons every 3 hours, we can calculate the decrease in gallons per day as follows:
Number of 3-hour intervals in a day = 24 hours / 3 hours = 8 intervals
Decrease per day = 10 gallons * 8 intervals = 80 gallons
Now, we can calculate the total change in the amount of water in the tank after 6 days:
Total change = Decrease per day * Number of days
= 80 gallons * 6 days
= 480 gallons
Therefore, the total change in the amount of water in the tank after 6 days is 480 gallons.
To compute the total change in the amount of water in the tank after 6 days, we first need to determine the change in the amount of water that occurs in a single day.
Given that the water tank decreases by 10 gallons every 3 hours, we can compute the change in gallons per hour by dividing the decrease by the time interval:
Change in gallons per hour = 10 gallons / 3 hours
Next, we need to determine the number of hours in a day. Since there are 24 hours in a day, we can calculate the total change in the amount of water in a single day by multiplying the change in gallons per hour by the number of hours in a day:
Change in gallons per day = (10 gallons / 3 hours) * 24 hours
Finally, to find the total change in the amount of water in the tank after 6 days, we multiply the change in gallons per day by the number of days:
Total change in amount of water = Change in gallons per day * 6 days
By plugging in the values, we can compute the total change in the amount of water in the tank.
