To solve the expression (-2)×(15)÷(23)×(-56)÷(34), we'll apply the properties of operations and rules for multiplication and division step by step:
First, we'll solve the multiplication part: (-2) × (15) = -30.
Next, we'll divide -30 by 23: -30 ÷ 23 ≈ -1.304347826087.
Then, we'll multiply -1.304347826087 by -56: -1.304347826087 × -56 ≈ 73.043478260872.
Finally, we'll divide 73.043478260872 by 34: 73.043478260872 ÷ 34 ≈ 2.150455062961.
Therefore, the solution to the expression (-2)×(15)÷(23)×(-56)÷(34) is approximately 2.150455062961.

To solve this multi-step problem, we'll use the information given that the runner completes 1/4 of a 5-mile race every 8 minutes.
First, we'll find the distance the runner can cover in 1 minute by dividing 1/4 mile by 8 minutes: (1/4) ÷ 8 = 1/32 mile per minute.
Next, we'll find the distance the runner can cover in 16 minutes by multiplying the distance covered in 1 minute by 16: (1/32) × 16 = 16/32 = 1/2 mile.
Therefore, the runner can go 1/2 mile in 16 minutes. The answer is 2 1/2 miles.
First, we'll find the distance the runner can cover in 1 minute by dividing 1/4 mile by 8 minutes: (1/4) ÷ 8 = 1/32 mile per minute.
Next, we'll find the distance the runner can cover in 16 minutes by multiplying the distance covered in 1 minute by 16: (1/32) × 16 = 16/32 = 1/2 mile.
Therefore, the runner can go 1/2 mile in 16 minutes. The answer is 2 1/2 miles.

To find the total change in the amount of water in the tank after 6 days, we need to determine the change in gallons each 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 change in gallons each day as follows:
10 gallons/hour x 24 hours/day = 240 gallons/day.
Therefore, the tank decreases by 240 gallons each day.
To find the total change in the amount of water after 6 days, we multiply the daily change by the number of days:
240 gallons/day x 6 days = 1440 gallons.
Therefore, the total change in the amount of water in the tank after 6 days is 1440 gallons.
Given that the water tank decreases by 10 gallons every 3 hours, we can calculate the change in gallons each day as follows:
10 gallons/hour x 24 hours/day = 240 gallons/day.
Therefore, the tank decreases by 240 gallons each day.
To find the total change in the amount of water after 6 days, we multiply the daily change by the number of days:
240 gallons/day x 6 days = 1440 gallons.
Therefore, the total change in the amount of water in the tank after 6 days is 1440 gallons.
thats not hwat i asked
Apologies for the misunderstanding. Let's solve the problem correctly this time.
Given that the water tank decreases by 10 gallons every 3 hours every day, we need to calculate the total change in the amount of water in the tank after 6 days.
In 1 day (24 hours), the tank decreases by 10 gallons every 3 hours. Therefore, the tank will decrease by (10 gallons/3 hours) x 8 hours = 80 gallons in 1 day.
So, in 6 days, the total change in the amount of water in the tank will be 80 gallons/day x 6 days = 480 gallons.
Therefore, the total change in the amount of water in the tank after 6 days is 480 gallons.
Given that the water tank decreases by 10 gallons every 3 hours every day, we need to calculate the total change in the amount of water in the tank after 6 days.
In 1 day (24 hours), the tank decreases by 10 gallons every 3 hours. Therefore, the tank will decrease by (10 gallons/3 hours) x 8 hours = 80 gallons in 1 day.
So, in 6 days, the total change in the amount of water in the tank will be 80 gallons/day x 6 days = 480 gallons.
Therefore, the total change in the amount of water in the tank after 6 days is 480 gallons.

To find the correct number of calories per serving, we need to divide the total calories by the number of servings.
The recipe calls for 1/3 of a container of yogurt, which has 150 calories. To calculate the number of calories for 1 serving, we need to multiply 1/3 by 150 and then divide by the number of servings, which is 4.
The correct set of calculations to find the number of calories per serving is: 1/3 × 150 ÷ 4.
Therefore, the correct option is: 1/3 × 150 ÷ 4.
