Answer:
216
Step-by-step explanation:
the area is ((B + b) x h) / 2
which is ((22 + 14) x 12) / 2
make a proportion
<span>Let x = the amount of feet descended in 3 minutes (thus the total change of altitude of the balloon)
</span><span> 320 (feet per minute) / 1 (minute) = x (feet per minute) / 3 (minutes)
</span><span> 1) Divide: 320/1 = 320.
</span><span> 2) Multiply: 320 x 3= 960.
</span><span> The balloon that descends at a rate of 320 feet/minute (so, every minute, it descends 320 feet) descends a total of 960 feet in 3 minutes.
</span><span> The balloon's total change in altitude is -960 feet. </span>
