Range= 4
Range is the highest number minus the lowest number, 10-6=4
25% = 0.25
40 / 0.25 = 160
40 is 25% of 160.
There are 160 children in the club.
Write and solve the appropriate exponential equation:
228 = 16(r)^4, where r is the change per hour in the number of bacteria:
228
------ = r^4 = 14.25.
16
Taking the fourth root of both sides, we get: r = 1.94 (answer)
Well, for wheel 1, divide 1/3 to get .3333333333333333
for wheel 2, divide 1/4 to get .25
hope this helps
