only 6 of the 75 trees in the park are at leat 30 feet tall. what percent of the trees are over 30 feet?

Answers

Answer 1
Answer:

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 %

use pythagorean theorem to find the height as in diagram atachmetn
4^2+h^2=8^2
16+h^2=64
minus 16
h^2=48
sqrt both sides
h=4√3

multiply by 4

that way you can figure out how many pages per hour were read. so 98 times 4 is 392. so it is 392 pages per hour

The denominator says (1)/(4) of an hour. We know that an hour lasts 60 minutes, which means 1/4 hour can simplify into 60 * (1)/(4), which is (60)/(4) which simplifies into 15 minutes. This means that the simplified fraction is (98 pages)/(15 minutes).

Divide 36 in the ratio of 2 4 how do I divide a quantity into a ratio

Answers

Add up the 2 sides of the ratio. In a ratio of 2:4, one will get 2 shares and the other will get 4 shares. There are 2+4= 6 shares all together. The 6 shares add up to 36, so how much is each share ? It's. 36/6 = 6 in a share.<br />So the small side of the ratio gets 2 shares = 12, and the big side gets 4 shares = 24. The split is 12:24. Those numbers are in the ratio of 2:4 and they add up to 36. ====> Add the sides of the ratio to find the total number of 'shares'.

Answer:

12

What can be added to -1 so it can be a positive 1?

Answers

so represent missing number with x
x means unknown so
x+-1=+1
adding a negative means subtraction
x-1=1
you can do anything to an equation as long as you do it to both sides
add 1 to both sides
x+1-1=1+1
x+0=2
x=2

the number is 2
