Find how many half lives have passed
seems we are measuring in days
half life formula is as follows
A=final amount
P=initial amount
t=time in a certain units (this time, it's days)
h=time of half life
so
we are given that P=1, A=0.6, t=3
find h
subsitute
take ln of both sides
multiply both sides by h
divide both sides by ln(0.6)
use your calculator
h≈4.07075
so about 4 days is the half life
According to AAA Chicago, 58 percentage of crashes involving teen drivers are instigated by distracted driving.
What does AAA study tell about the distracted driving of teens?
According to the AAA Foundation for Traffic Safety's review of over 1,700 crash films, distracted driving causes 58 percent of car accidents involving juvenile drivers. According to the foundation, this figure is four times higher than earlier projections derived from police records.
The investigation identified 12 different kinds of distracted driving that contributed to collisions, with passenger interaction accounting for 15% of crashes. Twelve percent of the collisions were caused by using a cellphone, which was followed by reaching for something, looking inside the vehicle, gazing outside while not paying attention to the road, singing or dancing, and looking at something outdoors.
According to the study, young drivers were prey to distracted driving by calls, texts, or other mobile device use for an average of 4.1 seconds in the final six seconds before a catastrophic crash.

Answer:
56,250
Step-by-step explanation:
First e turn the persentage into a decimal so we can multiply the 45,000 by it
45,000 x 0.25 = 11,250
Now we ad the total from last month to the amount we got in the last step to figure out how much the company earned this month
11,250 + 45,000 = 56,250
The company earned 56,250 this month :)
Hope this helped!
Have a good day!

26)In order to calculate the mean, the average must be determined. In this scenario, the mean is determined by dividing 60 by 5.
alligator population is 12.
27) you just divided 105/7 the answer is 15
Answer:
Step-by-step explanation:
we know that
In a rhombus the diagonals are perpendicular
so
The triangle ABE is a right triangle
see the attached figure to better understand the problem
Applying the Pythagoras Theorem to the right triangle ABE
where
AB is the hypotenuse of the right triangle (greater side)
AE and BE are the legs of the right triangle
we have
substitute
solve for BE
