Answer: A. divided the difference of the two quantities by the sum of the two quantities.
===================================================
Explanation:
The difference of the quantities is 20-15 = 5
The sum of the quantities is 20+15 = 35
Dividing those results leads to 5/35 = 0.142857 which rounds to 0.1429
That converts to 14.29%
This is likely the path Adam took. This path is incorrect. The correct steps are shown below
---------------------
Difference = 20-15 = 5
Divide the difference over the original quantity
5/20 = 1/4 = 0.25 = 25%
We have a 25% decrease because the new quantity (15) is smaller than the old quantity (20)
----------------------
Here's another way to approach the problem
A = old value = 20
B = new value = 15
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (15-20)/20 ] * 100%
C = (-5/20)*100%
C = -0.25*100%
C = -25%
The negative C value means we have a negative percent change, ie we have a percent decrease. So this is another way to get a 25% decrease.
Answer:
Predicting the next item in a pattern is an example of inductive reasoning.
A. (True)
Step-by-step explanation:
With compass setting the same as PA. place the compass at P and draw an arc above the diameter.
<h3>What is a Hexagon?</h3>
This is a polygon which has a total number of six sides and internal angle which is 720 degrees.
The compass should be placed at P and an arc above the diameter after which they are joined to form a hexagon.

Answer:
This question is incomplete
Step-by-step explanation:
This question is incomplete. However, there are mainly four types of graphical representations in mathematics; line graph, bar graph (and histogram), pie chart and cartesian graph. The most suitable representation for fluctuating data sets of the same variables on each of the y and x-axis is the line graph. Since download speed will fluctuate during the course of a download, the correct type of graph to be used here will be the line graph. And the exact type of line graph that will be used here is a simple line graph. A simple line graph is a type of line graph in which one line is drawn on the graph. A simple line graph is usually used to represent two variables (in this case data downloaded per time).
Ah clever. So you need two formulas.
1) Volume of the marble.
4(pi)r^3/3
= 4(pi)(1.4)^3/3
<span>= 11.49 (approx)
</span>
2) Formula for density.
D = M / V
= 9 / 11.49
= 0.78
0.78 < 1
Therefore the marble will float.
