Answer:
Step-by-step explanation:
10^4 = 10000
1.7 × 10^4 = 1.7 × 10000
= 17000
10^-2 = 1/10^2= 1/100
8.5 × 10^-2 = 8.5 × 1/100
= 17/200
Final answer = 17000 × 17 / 200
= 1445
Plz mark it as brainliest
Simple, first change the 4.5% into 0.045
Thus,
900=0.045*n
900/0.045=0.045n/0.045
20,000=n
Thus, your answer is 20,000.
Astronomers deal with objects in space, so it's most likely they would use geometry to determine how far they are, how big they are, etc.
Have a nice day! :)
Answer:
The first one
Step-by-step explanation:
An easy way is SOH CAH TOA
SOH is that you use sine if you there is the opposite (in this case the question mark) and hypotenuse (the diagonal line)
CAH is that you use cosine for the adjacent side (1100) and the hypotenuse.
TOA is using tangent for the opposite and adjacent side.
To fine the question mark, you would use tangent. And plug in the given (1100 for the adjacent). So tan45 = x/1100.
