Since the deepest point of Death Valley is below sea level, its altitude is negative. So, the difference between the altitudes is
Subtracting a negative means to add, so we have
So we want to know what percentage of bees would survive a virus after 19 days of decay if the bee population has a half life of 5 days. So every 5 days 50% of bees die. Lets say that N is the number of bees before the virus. So after 5 days is 50% less bees, so 50% of N remains. After another 5 days again, 50% bees die, and 50% out of 50% is 25%. So after 10 days, 25% of bees remain or 25%N or 0.25*N. After another 5 days its 12.5 % of bees remain or 0.125*N. And after 4 days 40% more bees die. And that is 0.4*0.125*N = 0.05N. 0.05*100% is 5%. So after 19 days, 5% of bees remain and 95% of bees is dead.
I THINK this may be the answer not 100% sure tho!
1. Two forces equal and acting in opposite direction result in zero force.
2.Sum of two moment of forces acting in opposite sense produce zero resultant.
Any two equal and opposite vectors produce zero net effect
Answer:
z=2
Step-by-step explanation:
5/20=z/8
Rewrite the equation as z/8=5/20
z/8=5/20
Multiply both sides of the equation by 8.
8⋅z8=8⋅520
Simplify both sides of the equation.
z=2
Hope this helps! Plz mark as brainliest! :)
