Answer:
400 ping pong balls
Step-by-step explanation:
Let the total number of ping pong balls =x
Out of x ping pong balls, 80 are marked with a blue dot
Out of 80 ping pong balls, 16 are marked with a blue dot.
Expressing it as a ratio:
x:80=80:16
There are an estimate of 400 ping pong balls in the container.
The slope of the line that passes through the points, (3, 4) and (-4, -5) is: A. 9/7.
<h3>How to Determine the Slope of a Line?</h3>
The slope of a line can be calculated by using the slope formula, which is given as:
Slope (m) = change in y / change in x or rise / run.
Given that the following points lie on a line:
The slope of the line would be solved using the slope formula as explained below:
Slope (m) = change in y / change in x = (-5 - 4) / (-4 - 3)
m = -9 / -7
Slope (m) = 9/7.
Therefore, the slope is identified as:
a. 9/7.
