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
480 gallons
80 gallons
-480 gallons
-80 gallons
The tank decreases by 10 gallons every 3 hours. There are 24 hours in a day, so the tank decreases by 10 * (24/3) = 10 * 8 = <<10*(24/3)=80>>80 gallons per day.
After 6 days, the total change in the amount of water in the tank will be 80 * 6 = <<80*6=480>>480 gallons.
Therefore, the correct answer is 480 gallons. Answer: \boxed{480\text{ gallons}}.
A recipe calls for 1/3 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
1/3 x 150x4
1/3 ÷150÷4
1/3x150÷1/4
1/3x150÷4
To find the number of calories per serving, we need to determine the amount of yogurt used in the recipe and divide it by the number of servings.
The recipe calls for 1/3 of a container of yogurt. Since each container has 150 calories, the amount of yogurt used in the recipe is (1/3) x 150 = 50 calories.
The recipe makes 4 servings, so the number of calories per serving is 50 / 4 = 12.5 calories per serving.
Therefore, the correct set of calculations to find the number of calories per serving is 1/3 x 150 ÷ 4. Answer: 1/3 x 150 ÷ 4.
To find the total change in the amount of water in the tank after 6 days, we need to determine the change in the amount of water per day and then multiply it by the number of days.
Given that the water tank decreases by 10 gallons every 3 hours, we can calculate the amount it decreases in one day as follows:
In 24 hours, there are 8 sets of 3 hours (24 divided by 3), which means the water tank decreases by 10 gallons x 8 sets = 80 gallons in one day.
Therefore, the total change in the amount of water in the tank after 6 days is 80 gallons x 6 days = 480 gallons.
So, the correct answer is 480 gallons.
