Answer:
4*(Q+25) Q=2
Step-by-step explanation:
4*(2+25) = 4*27 = 108
19/20 is the simplest form
Answer:
year 2139
Step-by-step explanation:
The population will double when the factor e^(.005t) is 2.
e^(.005t) = 2
.005t = ln(2)
t = ln(2)/0.005 = 138.6
The population will be double its size at t=0 when t=138.6. That is the population will be about 5.2 million in the year 2139.
In order to find the number of hours it takes to do the full rotation we separate into pieces the days, hours, and minutes and convert each of them separately.
using the conversion factor from days to hours we get that

then we get that

hours does not need a conversion factor, meaning that

continue by converting the minutes using the following conversion factor

then,

To complete add all the results together

It takes mercury 922.5 hours to complete a full rotation.
Answer:
y = 
Step-by-step explanation:
Given
ya + yv = t ← factor out y from each term on the left side
y(a + v) = t ( divide both sides by a + v )
y =
