Answer:

Step-by-step explanation:
See attachment for complete question.
We start by solving for the equation of the graph (The graph shows a linear equation)
Represent pencils with x and pen with y
From the graph, we have that:


Solve for slope (m)




The equation is calculated using:

Where







Add 4 to both sides


Now, to the question.
When pencils is 15 implies that

Solving for x, we have:





i.e. Pen = 10
Ratio = x ; y

Convert to fraction

Simplify

Hence,

Answer:
8
Step-by-step explanation:
The property of the two chords intersecting each other within the circle is
AO.OB=CO.OD
Where AB and CD are two chords as shown in the image attached with this.
Hence
here we are given that
AO = 10 , OB=4
CO=5 , OD=X
Hence
10*4=5*x
5x=40
dividing both sides by 5 we get
x=8
Hence our answer is 8
Answer:
b = 1/3 a.
Step-by-step explanation:
The number in b = 1/3 of the number in a.
b = 1/3 a.
Answer:
it does not.
Step-by-step explanation:
3(5)-3(4)=15
15-12=15
3=15
