Answer:
A) 2 miles, 5 miles, 8 miles
Step-by-step explanation:
Let's get some details cleared.
We're interested in finding how many miles he walked at the end of each hour in a period of 3 hours.
We know what is, so we can use that as our starting point.
Your answer is A.
Answer:
I believe it should be
4 : 1 : 200
Step-by-step explanation:
Answer:
15°
Step-by-step explanation:
If CB is a diameter, the arc BKAC is a semicircle and has a degree measure of 180. If the measure of angle BCK is 20 and it is an inscribed angle, then the measure of the arc it intercepts is twice that. So arc BK measures 40 degrees. That means that arc KA has a measure that is found by subtracting arc AC and arc BK from 180. 180 - 40 - 110 = 30. If that arc is 30 and the angle that intercepts it is inscribed, then the angle measure is half the measure of the arc. So the angle is 15°
F=ar^t if the half-life is 96 years...
.5=r^96
ln(.5)=96lnr
ln(.5)/96=lnr
r=e^((ln.5)/96)
f=800e^(336(ln.5)/96)
f=70.71
So about 71mg will remain after 336 years.
