Answer:
if the only choices were pepperoni and cheese then 590 students were surveyed. I think there may be more to the question that you left out by accident
12/25 * 100 = 48%
Amount/Whole Amount * 100
I'm not sure how you obtained -5 as your answer but this is the mathematical explanation. hope this helps!
Jeb took 1/4 of 100 minutes(1 hour 40 minutes) =25 minutes for the first lap. . so the rest 75 minutes , Jeb took 1/3 time so 25 minutes for the second lap , the third lap Jeb took 100-50 = 50 minutes .
1) the square root of 64=8
2) The square root of a^4=a^2
3) b^5=b√b
so the first amount simplifies to 8a²b²√b
4) ∛64=4, as 4×4×4=64
5) ∛a^5=a√a²
6)∛b^4=b√b
so...the second amount is equal to 4ab∛a²b
The last one should be correct
Hope this helped :)
