Answer:
8 %
Step-by-step explanation:
To find the percent of trees that are over 30 ft tall, take the number of trees that are over 30 ft tall over the number of tree
Percent = trees over 30 ft tall/ total number of trees
= 6/75
=.08
Change this to a percent by multiply by 100%
.08 * 100%
8 %
Explanation
The shaded area represents a segment. This can be solved with the formula below;
![\mleft(\frac{\theta}{360}\mright)\times\pi r^2-\frac{1}{2}r^2sin\theta](https://tex.z-dn.net/?f=%5Cmleft%28%5Cfrac%7B%5Ctheta%7D%7B360%7D%5Cmright%29%5Ctimes%5Cpi%20r%5E2-%5Cfrac%7B1%7D%7B2%7Dr%5E2sin%5Ctheta)
Since the triangle is an equilateral triangle, it implies that the angle subtended at the centre is 60 degrees. Also, the given radius is 7 cm

Answer:
2 balloons = h/4 15 balloons = a/30 10 balloons = c/20 21 balloons = i/42 3 balloons = f/6 4 balloons = k/8 5 balloons = j/10
Step-by-step explanation:
Every time you have a number of balloons, since each costs 2 dollars, you would double the number of balloons to get the price of all of the balloons! Hope this helps! Have a great day!
