Answer:
A
Step-by-step explanation:


Remember that
x^(b-c)
Using that
=3^(1/2x-1/2)=3^((x-1)/2)

So we can say:
, because the bases are the same
We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.

Now we calculate the length of arc by arc formula
So, The length of steel that must be replaced is 4.708 ft.
Answer:
356.53
Step-by-step explanation:
Calculate the semicircle and square areas separately. For the semicircle, A = πr²/2, so 100.53
And for the square, A = a², so 256
Hope this helps
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.
