If you want it estimated it would be .55 which would be 55/100 which would simplify to 11/20
Answer:
12. 6.4
13. 20
Step-by-step explanation:
This is the Pythagorean theorem, which says a^2+b^2=c^2. So for problem 12 we have 4^2+5^2=c^2. Since, 16+25=41, c=sqrt41 which is about 6.4. For problem 13 we have 15^2+b^2=25^2. Since 25^2-15^2=400, b=sqrt400 which is 20. Hope this helps!

Answer:
8
Step-by-step explanation:
Note that √ signifies "square root."
If you're unsure of what √64 is, then make a short table of perfect squares until 64 comes up:
1 1
2 4
3 9
4 16
5 25
6 36
7 49
8 64
Thus, the square of 8 is 64 and so √64 = 8
