only 6 of the 75 trees in the park are at least 30 feet tall. what percentage of the trees are under 30 feet tall?

Answers

Answer 1
Answer: Total number of trees in the park = 75
Number of trees that are at least 30 feet tall = 6
Then
Number of tress that are less than 30 feet tall = 75 - 6
                                                                          = 69
So
Percentage of trees that are less than 30 feet tall = (69/75) * 100
                                                                                = (69 * 4)/3
                                                                                 = 276/3
                                                                                 = 92 percent
So the percentage of trees that are below 30 feet is 92%. I hope the procedure is clear enough for you to understand.
Answer 2
Answer: Hi

75-6 = 69 trees

69/3 = 23
75/3 = 25

69/75 = 23/25 = 0,92 = 92% are under 30 feet tall

    23 |_25_
- 230  0,92
  225 
 -------
   050
 - 050 
   ------
      0

the triangle on the left area is 18 because the area of a triangle is 1/2 b times h so 12 times 3 times 1/2 equals 18.you then cut a triangle from the quadrilateral to make into a triangle.The triangle is the same height has other triangle so its area is 18.Since you took three for base of left and right triangle you subtract 6 from 1 to make it your base of 8 and your height is 12 and 12 tikmes  8 is 96 so 18+18+96=132 so our answer is 132.

Games at the carnival cost $3 each. The prizes awarded to winners cost the owner $145.65. How many games must be played for the owner of the game to make at least $50?

Answers

Profit is the financial benefit relied when revenue generated from a business activity. The number of the games must be played for the owner of the game to make at least $50 is 63.

Given information-

The cost of the games at the carnival is $3 each.

The prizes awarded to winners cost the owner $145.65.

Profit of the owner is $50.

Profit

Profit is the financial benefit relied when revenue generated from a business activity.

As the winning amount of the game is $145.65 and the owner has to earn the $50. Therefore the amount of the game should be the sum of winning price and the profit. Suppose x is the total money of the game played. Therefore,

x=145.65+50\nx=195.65

Hence the total price is $195.65. The cost of the each game is $3. Thus the number of game n to be played are,

n=(195.65)/(3) \nn=65.21667

Hence the number of the games must be played for the owner of the game to make at least $50 is 63.
