A = 30,000 - 2000m where A=altitude and m = number of minutes
After 5 minutes A ( altitude) = 30,000 - 2000(5) = 20,000 feet
Answer: v = 3/7
Step-by-step explanation:
5 ( 6 - 4v ) = v + 21
30 - 20v = v + 21
30 - 20v - v = 21
30 - 21v = 21
-21v = -30 + 21
-21v = -9
v = -9/-21
v = 3/7
The answer is the temperature goes down 2.8° every hour and the expression is x=-11.2/4 because 4 is how many hours between 6pm and 10pm and its -11.2 because that was how much the temperature dropped from 6pm to 10pm
Answer:
7mm
Step-by-step explanation:
Area=l*b
35cm²=l*50mm
350mm²/50mm=l
7mm=l
