aye so the unit rate of the buttons and bows is .25 so if you go through the answers 7 and 28 is equal to .25
When you divide 287 by 68, when it is not rounded, you will get 4.22058823529... (repeated decimal), but when you round it, you can either get the following: 4.22, 4.2, or 4 (choose which ever you want to pick out of these rounded forms.)
Hope this helped!

Answer:
solution is attached in the picture below
Step-by-step explanation:
Answer:
383 students
Step-by-step explanation:
Average IQ = 115
So for IQ of 145 it's not average again.
So , 145 IQ should be 1/4 of the total number because it's no longer average .
So 1/4 of 1531 = 382.75 students approximately = 383 students
This answer is based on the assumption that average IQ is around 115.
So any one with IQ of 145 is not longer an average person concerning IQ.
If the height Ration is a/b, then
The ration of the arias S₁ & S₂==> S₁/S₂ = a²/b² and
The ration of the volumes V₁ & V₂==> V₁/V₂ =a₃/b₃
V₁ =135 cm³ the ration of the heights = 3/2, Calculate V₂
V₁/V₂ =3³/2³ = 27/8===> 135/V₂ = 27/8==> V₂=(135x8)/27 = 40cm³
