Hey!!!

according to the question, there are 420 silver birch trees, 160 oak trees and 300 wild berry trees.

we have to find the percentage of the oak trees.

total number of trees = 420 + 160 + 300

= 880 trees

no. of oak trees is given = 160

therefore it's percentage = 160/880 × 100

= 16/88 × 100

= 2/11 × 100

= 200/11

= 18.18% (approx.)

cheers!!!

I would be happy to help!
First you need to find the total amount of trees by adding up all of the different trees:
420+160+300=880
Next you need to divide the amount of oak trees by the amount of trees in the woods:
160÷880=0.182 (rounded)
Finally to find the precentage we need to multiply the 0.182 by 100 to get the precentage of 18.2% oak trees.

The walls of a room are representations of what basic element of geometry? A. point B. line C. plane D. ray

kkurt [141]

In geometry,

A point represents a point

Two points define a line extended on both sides of the points.

Two points define a ray if it extends on only one side of either of the points.

Three or more than three points define a plane.

Now as far as a wall is considered, it is a flat surface on which we can plot infinite points.

Hence the wall represents a plane.

Option C) is the right answer.
