C. y= [25,100]
you need brackets because the points actually touch the number
Answer:
4√5
Step-by-step explanation:
c = √a² + b²
c = √4² + 8²
c = √(16 + 64)
c = √80
c = 8.94427 (rounded to nearest 1/100000)
c = 4√5
Answer:
81.25
Step-by-step explanation:
Answer:
28%
Step-by-step explanation:
Lets say the fraction of speed and problem solved is 100/100
the number of problems solved increases by 60%
so now it is 160/100, also the speed increases by 25%
so now we do 160/125=1.28
finaly we do 1.28-1 = 28%
Therefore the answer is 28%.
hope this helps
