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:
30%
Step-by-step explanation:
24/80 = 0.3
move the decimal over 2 times and you'll get your answer
As all real number I think
So add
1/5+3/8
convert bottom number to same number
5 times 8=40
bottom mub be 40
1/5 times 8/8=8/40
3/8 times 5/5=15/40
add
1/5+3/8=8/40+15/40=(8+15)/40=23/40
so completed 23/40 total
