8 meters increased by 25 : (8 + 25) = <em>33 meters</em>
=========================================
If you really meant to say "increased by <u><em>25 percent</em></u>" . . .
25 percent means 0.25
0.25 x 8 = 2 <== that's the increase
8 + 2 = <em>10 meters</em>

Answer:
B
Step-by-step explanation:
So remember that a quarter of a circle is 90 degrees, a half of a circle is 180 degrees, and a whole circle is 360 degrees.
Looking at the image shown, it must be half a circle, whihc is 180 degrees. The image tells us that the 1st angle is 7 degrees. Now, we must find the 2nd angle.
Heres what we know however:
angle 1 + angle 2 = 180 degrees.
How do we know this?
Well, there are only 2 angles in this 180 degrees. We know that the first one is 7 degrees.
Lets input that into our nice lil equation to get an answer:
7 degrees+angle 2 = 180 degrees
Now lets solve.
Subtract 7 on both sides, and your left with:
angle 2 = 173 degrees.
So the answer must be:
<u>173 degrees</u>
Hope this helps! ;)
Use inverse proportion ratio: xy=k
(124)(7)=k
k=868 (this is our constant)
now substitute the constant into the inverse proportion ratio knowing the number of workers
28x=868
solve for x by dividing both sides by 28 to find the time it takes to build the house
x=31 days
so it will take 31 days for 28 workers to build the house
