Answer:

Step-by-step explanation:
To find : Convert 110 km/myr (kilometers per million years) to cm/yr (centimeters per year) ?
Solution :
Using metric conversions,
1 kilometer = 1000 meter
1 meter = 100 centimeter
So, 1 kilometer = 100,000 centimeter
and 1 million year = 1,000,000 year


So, 

Therefore, 
Patrick because he can run 1 lap in 90 seconds
Answer:
16x^4+32x^3+24x^2+8x+1
Step-by-step explanation:
(2x+1)^4
(2x+1)*(2x+1)*(2x+1)*(2x+1)
Answer:
lets use what we know.
given lengths are: 6, 3, 6, and 15.
We need to split the right triangle from the small little rectangle.
Now we add the lengths of the triangle to get the full length:
6 + 6 = 12
now we need to find the base:
15 - 3 = 12
Now we get our area of the triangle:
12 x 12 = 144
144 divided by 2 = 72
Now the small rectangle's area:
6 x 3 = 18
Add both of their areas to get:
72 + 18 = 90 ft2
