A missile was fired from a submarine from 220 feet below sea level. If the missile reached a height of 10400 feet before exploding, what was the change in the altitude of the missile?

10,620

Step-by-step explanation:

Since it reached a height of 10,400 before exploding and was 220 feet below sea level we need to add the two numbers together to get the total change in altitude.

You can think of it as sea level = 0 so 220 feet below sea level is -220 and 10,400 above sea level is +10,400 so what's the difference between the two.

Finding the Difference

10400 - (-220)

=  10400 + 220

=  10620

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
