The answer is 81.1 because since the 9 place value above 5, you round the number in front of it to 1. so the answer is 81.1. I hope that helps.
Answer:
720º
Step-by-step explanation:
We can use vertical angles to figure this out. We can see that each of the unmarked angles in the triangles is a vertical angle to an empty space. A full circle has the measure of 360º. We need half of that which is 180º.
The sum of the angle measures of a triangle is 180º. We have five triangles so the total angle meaure is 900º.
However, we need to subtract the 180º to get 720º.

To solve this problem we can use simple proportion
If
270$ -------------------------3000 pesos
x $ ---------------------------100 pesos (x$ means that we dont know how much)
Now we crossmultiplying to get proportion
x*3000=270*100
Now we just to solve eq
3000x=27000 /:3000
x=27000:3000
x=9$ - its the result
63 = 9k
divide by 9 on each side to get k by itself
k = 7
