Pen=x
Pencil=y
y+0.15=x
y+x=0.69
y+y+0.15=0.69
2y=0.69-0.15
2y=0.54
y=0.54/2
y=0.27 pencils
y+0.15=x
0.27+0.15=x
0x=0.42 pen
150 pencils x0.27=40.5$
225 pens x 0.42=94.5$
Total 40.5$ + 94.50$=135 $

Step-by-step explanation:
A circle is characterized by radius, arc, sectors and circumference
- The length of the major arc is

- The radius of the circle is 15
- The area of the shaded sector is

<h3>Length of the major arc</h3>
The given parameters are:
--- the circumference
-- the center angle
The length of the major arc is calculated using:

So, we have:

Evaluate

Hence, the length of the major arc is 
<h3>The radius of the circle</h3>
The circumference is given as:

So, we have:

Divide through by 2pi

Hence, the radius of the circle is 15
<h3>The area of the shaded sector</h3>
The area of a sector is:

So, we have:

Evaluate

Hence, the area of the shaded sector is

Step-by-step explanation:
Answer:
Step-by-step explanation:
Step 3:
Let LM = x
OK = KP = 12 units [Radii of circle K]
LN = LP = 8 units [Radii of circle L]
Therefore, KL = KP + PL
KL = 12 + 8
= 20 units
Step 4:
Since, ΔKOM and ΔLNM are the similar triangles,
By the property of two similar triangles, corresponding sides of these similar triangles will be proportional.


12x = 8(x + 20) [By cross multiplication]
12x = 8x + 160
12x - 8x = 160
4x = 160
x = 40
