140 = 10x + 5y
24 = x + y

x = 4
y = 20

x is the number of $10 bills   (So 4 $10 bills)
y is the number of $5 bills     (So 20 $5 bills)

Answer:

please mark me as brainlist please

Step-by-step explanation:

Correct option is B)

The circumference of the circle is 96 units.

Therefore, 2π×r=96

⇒r=

2×22

96×7

=15.27 units

Now, in the quadrilateral OLMN,∠OLM+∠LMN+∠MNO+∠NOL=360

o

Given that LM and MN are tangents to the circle, ∠OLM=∠ONM=90

o

∴∠NOL=360−90−90−60=120

o

The length of arc is given by rθ where θ is the angle made by the arc at the centre in radian.

Thus, arc length LN=15.27×

180

120π

=31.98
