Answer:
square kilometers
Step-by-step explanation:
The surface area of a sphere can be found using the formula 
. Since the diameter is 3500 km then its radius is half of this. 3500 divided in two is 1,750 units. Substitute r=1,750.
The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base.
The general term is obtained by starting with the initial value 5 and then subtracting 4 each time you wish to generate a new term:
a2 = second term = 5+(2-1)(-4) = 5+(-4) = 1
General term:
an = nth term = 5+(n-1)(-4)
Thus, the 21st term is 5+(21-1)(-4) = 5 + (20)(-4) = -75 (answer)
Answer:
3
Step-by-step explanation:
slope is rise over run
6/2 simplifyed is 3/1 or just 3
Interestingly enough, the line x=8 is parallel to the y axis. The line x=8 means that x=8 no matter what y equals.
So any line that is parallel to the y axis could be the answer.
x=4
x=12
x=-17
x=-2.5 are all examples of lines that are parallel to x=8. Perhaps that will answer your question.
Answer:
97 1/2 miles in 1 hour and 30 minutes.
Step-by-step explanation:
I think your asking how many miles he travels in 3/2 of an hour.
He travels 65 miles in 1 hour but because he's been traveling 3/2 of an(=1 hour and 30 minutes because 2 is 1 hour so he has 1 whole or one hour and still has 1/2 so 1/2 of an hour=30 minutes.
He travels 32.5 miles in 30 minutes. And that should be your answer he travels 32.5 miles every 30 minutes.
Here's calculations.
32.5 x 1(30 minutes)=32.5
32.5 x 2(1 hour)=65
32.5 x 3(1 hour and 30 minutes)=97.5
Hope it helps have a great day:)
