Answer:
-19+-25f≤-144
Step-by-step explanation:
The problem says that you descended 19 below sea level. Below makes 19 into a negative. It also says that it descends 25 feet per minute. If it says per you put a variable by that number. It also says descends which means going down so that would be a negative. The problem says Lainey does not want to go over 144 feet(144 is also negative because it is below sea level) so 144 would be greater than or equal to because she does not wan to go over that amount.
Hope this helps!
Using the concept of probability, the probability of not landing on <em>yellow or red at all</em> is 1/4.

- <em>Probability</em><em> </em><em>=</em><em> </em><em>required</em><em> </em><em>outcome</em><em> </em><em>/</em><em> </em><em>Total possible</em><em> </em><em>outcomes</em><em> </em>
P(without Red or Yellow) = 4/16 = 1/4
Hence, the probability of not landing on <em>yellow</em><em> </em><em>or</em><em> </em><em>red</em><em> </em><em>at</em><em> </em><em>all</em><em> </em>is 1/4.

Answer:
127 square ft
Explanation:
The formula to find the area of a circle with a know circumference is: C^2/4 π.
40^2 is 1600 and 4 times pi is 12.56. Divide 1600 by the 12.56 and you will get your area of 127.39. The answer is 127 square ft after rounding to the nearest square foot.
Nicks rate is 7 yards per second.
