Answer:</h2>
The number of trees which are less than 20 meters are:
9
<h2>
Step-by-step explanation:</h2>
Based on the histogram we are asked to find the number of trees which are less than 20 meters in height.
Class interval Frequency
4-8 1
8-12 2
12-16 2
16-20 4
20-24 6
24-28 4
28-32 2
i.e. we are asked to find the total number of tress that lie in the class interval 4-20.
i.e. we add the frequencies that lie in the interval 4-20
i.e. Number of trees= 1+2+2+4=9 trees.
2x + 7y + 3x - 4y
Collect all the like terms:
2x + 3x = 5x
7y - 4y = 3y
And you end up with 5x + 3y as your final answer :)
First, change the fractions to a common denominator, which is 21.
so 3/7 * 3/3 = 9/21
1/3 * 7/7 = 7/21
Add the two together
9/21 + 7/21 = 16/21
Then take 21/21 - 16/21 = 5/21
There is 5/21 of the pizza left.
Step-by-step explanation: A coordinate grid has two perpendicular lines, or axes (pronounced AX-eez), labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin
