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.
To find the balloon's total change in altitude, we need to multiply the descent rate by the amount of time it descends.
Change in altitude = Descent rate x Time descended
Descent rate = 320 feet per minute
Time descended = 3 minutes
Change in altitude = 320 x 3
Change in altitude = 960 feet
Therefore, the balloon's total change in altitude is 960 feet.
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?
To find the average change in volume per month, we need to divide the total change in volume by the number of months.
Total change in volume = 21,000 cubic yards
Number of months = 3
Average change in volume per month = Total change in volume / Number of months
Average change in volume per month = 21,000 / 3
Average change in volume per month = 7,000 cubic yards
Therefore, the average change in volume per month is 7,000 cubic yards.
Write and solve an algebraic equation to find the answer.
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?
Let's call the temperature at midnight "x".
From midnight to 6:00 am, the temperature rose 8°C, so at 6:00 am, the temperature was x + 8.
We're also given that at 6:00 am, the temperature was -20°C.
So we can set up an equation:
x + 8 = -20
To solve for x, we can subtract 8 from both sides:
x = -28
Therefore, the temperature at midnight was -28°C.
