Denali, north america's highest peak, is 20,310 feet above sea level. death valley is 282 feet below
sea level. what is the difference between their two positions?

The difference between the two position = 20,028 feet

Step-by-step explanation:

North America highest peak distance above sea level = 20,310 feet

Death valley distance below the sea level  = 282 feet

Let the sea level be = X

Highest peak point = Y

Death valley point = Z

So As per question

Distance from X to Y = 20,310 feet

Distance from X to Z = 282 feet

So, difference between two points = (X + Y )  - (X + Z ) = Y - Z

So , Y - Z = (20,310) - (282) = 20,028 feet

Hence the difference between the two position = 20,028 feet  Answer

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
