suddenly the number of math problems mathletes had to solve increased by 60%! to keep on track the mathletes try to go faster bu
t only increase their speed by 25% By what percent must the number of mathletes on the team increase so they can solve all the problems on time?
1 answer:
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

Rectangular with whole numbers
perimiter=legnth+legnth+width+width=2l+2w
therefor
p=2l+2w=2(l+w)
p/2=l+w
perimiter=20
20=2l+2w
divide by 2 to make simpler
10=l+w
find all combos
l>w so
l=9 and w=1
l=8 and w=2
l=7 and w=3
l=6 and w=4
combos
Answer:
y=-1/5x-9/5
Step-by-step explanation:
y=-5x-9
x=-5y-9
-5y=x+9
y=-1/5x+9/-5
y=-1/5x-9/5
