Answer:

40% of the band members are eighth graders.

Step-by-step explanation:

There can only be a total of 100%.  The problem already gives us the percentages of sixth graders and seventh graders, and it tells us that there are only eighth graders left.  Subtract the sum of 40 and 20 from 100 to get your answer.

100% - (40% + 20%) = 40%

If a wagon wheel has a diameter of 70cm, how many revolutions would it take to travel 66 METERS?
ddd [48]

Answer:

30 revolutions

Step-by-step explanation:

to calculate the revolution of the wheels in 66 metres we need to get the circumference

circumference = 2πr, r = radius (diameter divided by 2) but from the formula of circumference we ca rewrite it as πd= 3.14 x 70 = 219.8cm

next convert 66 metres to cm

100cm = 1m

x= 66m

cross multiply

x= 66m x100cm/1m= 6600cm

revolutions in 66metres = 6600cm/219.8cm = 30.0272975 ≅30 revolutions
