A hot air balloon descends at a rate of 320 feet per minute for 3 minutes. Use integers to calculate and represent the balloon's total change in altitude.
The volume of water in a reservoir decreases 21,000 cubic yards over a 3-month period. What is the average change in volume per month?
From midnight to 6:00 am, the temperature rose 8°C. At 6:00 am, the temperature was
-20 °C. What was the temperature at midnight?
Please and thank you!
noooo
? help ? how do I solve this no answers plz just tell me how I do it myself
To calculate the balloon's total change in altitude, we can multiply the descent rate by the time it descends. Since the balloon descends at a rate of 320 feet per minute, and it descends for 3 minutes, the total change in altitude is:
320 feet/minute * 3 minutes = 960 feet
So, the balloon's total change in altitude is 960 feet.
To find the average change in volume per month, we divide the total change in volume (21,000 cubic yards) by the number of months (3 months).
Average change in volume per month = Total change in volume / Number of months
= 21,000 cubic yards / 3 months
= 7,000 cubic yards per month
Therefore, the average change in volume per month is 7,000 cubic yards.
To determine the temperature at midnight, we need to subtract the temperature rise from 6:00 am (8°C) from the temperature at 6:00 am (-20°C).
Temperature at midnight = Temperature at 6:00 am - Temperature rise
= -20°C - 8°C
= -28°C
Hence, the temperature at midnight was -28°C.
