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

Answer:
X=4
Step-by-step explanation:
30x+5=31x+1
x=4
B. You have to solve for X, and graph using whatever is less than or greater than. 4x + 12 < 4 to 4x < -8 to x < -2.
Yes, I can solve that inequality.
Any value of ' r ' that's less than 1/3 is a solution.
The area of the trapezoid is given by the formula A= (a+b)/ 2 * h
in this question a= 8, b= 10, A= 108 inches², and h is what we have to find, substitute what we have got into the formula and you will have:
108= (8+10) /2 *h
108= 9 *h
h= 108/9
h= 12 inches
Find the numbers and place them in for the letters
