Answer:
9
Step-by-step explanation:
14) The answer is a) y = 2x. 2 is the slope and the line does not cross over the Y axis in this picture so there is not a Y-intercept you can see.
15) You pretty much just estimate. On the graph when you find 50 minutes and go up its around 140. 50 x 2 is 100 minutes. so just multiply 140 by 2 and its 280 so just round to the closest one.
The perpendicular bisector theorem gives the statements that ensures
that 
and 
are perpendicular.
The two statements if true that guarantee is perpendicular to line are;
Reasons:
The given diagram is the construction of the line 
perpendicular to line 
.
Required:
The two statements that guarantee that is perpendicular to line .
Solution:
From the point <em>C</em> arcs <em>E</em> and <em>D</em> are drawn to cross line , therefore;
arcs drawn from the same radius.
is perpendicular to line , given.
Therefore;
by perpendicular bisector theorem.

The estimate for the total number of bees in her hive is 190 bees
<h3>How to find the total estimate of the bees ?</h3>
She catches 90 of the bees on Monday and she puts mark on each bees and return them to her hive.
On Tuesday she catches 120 of the bees. She find out that 20 of the bees has been marked.
This means only 100 bees have not been marked on Tuesday.
Therefore, the total number of bee in her hives is as follows:
total number = 90 + (120 - 20)
total number = 90 + 100
total number = 190 bees
