Answer:
1
Step-by-step explanation:
note that
= 1 for any value of n, thus
= 1
If there are 45 beads, with a ratio of

Then,

Then if

Then

Therefore,

Meaning, there would be a ratio of 36 beads to 9 beads
All you do is use the a+b=c formula lets plug it in
15+b=35
15+20=35
35=35
The answer is 20
Yes I think it really is the correct answer
Answer:

Step-by-step explanation:
Given:
From the graph shown,
The broken line means that the inequality sign will be either < or >.
The shaded region is to the left of the broken line. This means that
.
Now, in order to find equation of line, we need slope and y-intercept.
From the graph, the y intercept is at
. So, y intercept is 1.
Also, if we consider two points
on the line, then slope is given as:
Therefore, the equation of the line is given as:

But as the shaded region is to the left of the line,
∴
is the correct answer.
