A perfect situation to use a proportion:
(3.9 x 10³³) / 1 = X / (2.45 x 10⁵) .
Solve that proportion for ' X ' in the usual way.
If you can't remember how to solve a proportion, then
THAT's what you have to go look up. It's much more
important to you right now than how much energy the
sun is putting out.
7.4 x 10⁴ mm is the same size as about 243 feet !
If the tracks on a DVD were that far apart, there would not be
room for very many tracks on a DVD. That's not reasonable.
If the tracks are 7.4 x 10⁻⁴ mm apart, then there are about
34,000 tracks in a stripe that's 1-inch wide. I have no idea
how they do this, but it's certainly more reasonable than the
other choice.
Answer:
C. 2 hours
Step-by-step explanation:
50h= 190-45h
50h + 45h = 190
95h = 190.
190÷95= 2h
You would do vide the numbers
Ex: a sloth travels 5 ft every 10 minutes. you would divide the numbers and the answer would be 2ft/min
which would be 2 feet per minute
<span>5(912−14)+0.5
= </span><span>5(898) +0.5
= 4490 + 0.5
= 4490.5</span>
The slope is the change in Y over the change in X.
(-9,6) is X1 and Y1.
(-3,9) is X2 and Y2.
Slope = Y2-Y1 / X2-X1
Slope = 9 - 6 / -3 - (-9)
Slope = 3/6 = 1/2
The slope = 1/2
