Answer:
20%
Step-by-step explanation:
Mr. Vella can build the wall in 4 days, however only works on it for 3 days. That means that he has completed 75% of the and is leaving 25% for his apprentice.
We need to figure out how long it takes the apprentice to build 25% of a wall. We know he can build 100% of a wall in 6 days, so dividing 6 days by 4 will give us our answer.
6/4 = 3/2 = 1.5 days
It took the apprentice 1.5 days to finish the wall.
Answer: 
Each term is half of the previous one, so the common ratio is 1/2. Then to get from the first term to the nth term, you have to take n - 1 steps, multiplying by 1/2 each time and by 6000 to account for the first term.

Dowloand mw it help you you can do it there 13.50*23
Rectangle perimeter is 53 meters.
L = W + 2.3
To find the options of a perimeter, divide by 4.
= 13.25
So if this was a square, it would be 13.25 for both L and W but it's not.
Since the W has 2.3 meters more then the L, we do this.
13.25 + 2.3 = 15.55
13.25 - 2.3 = 10.95
Two of your sides equal 15.55, and the other two equal 10.95.
Hope this helps!
