Answer:
It's 0.5x10^3
Step-by-step explanation: A number in scientific notation has to be between 1 an 10. It can't be less than one or 10.
You are NOT using scientific notation correctly. When you say 22^4 you are saying 22*22*22*22 which equals 234,256. What you should say is Earth to Moon distance = 22 * 10^4 miles. (To be really precise, it should be expressed as 2.2 * 10^5 miles).
Earth to Neptune distance = 2.2 * 10^8 miles.
2.2 * 10^8 / 2.2 * 10^5 = 1,000. So the Earth to Neptune distance is 1,000 times greater than the Earth to Moon distance.
Answer:
Can you add an image of the points on a graph so I can help?
3{-1 + 3 [ 7 - 2(-10 + 8)]} Work out ' inside' parentheses first:-
= 3{-1 + 3 [7 - 2*-2]}
= 3 { -1 + 3 [7 + 4]}
= 3 { -1 + 3*11}
= 3 * 32
= 96 answer
15 is the width because 30 times 2 equals 60 and 60 plus 30 equals 90 so 30/2 equals fifteen.
In short-30*2+w2=90
w=15
Hope this helps!
