Mathematics
1 answer:
Alika [10]3 years ago
5 0

Answer:

b = 55°

Step-by-step explanation:

The angle at the centre is twice the angle on the circle subtended by the same arc, then

a = 0.5 × 110° = 55°

Angles on the circumference subtended by the same arc are congruent, so

b = a = 55°

A new car is purchased for 15500 dollars. The value of the car depreciates at 7.5% per year. What will the value of the car be,
mixer [17]

Answer:

\$9,709.17  

Step-by-step explanation:

we know that

The  formula to calculate the depreciated value  is equal to  

V=P(1-r)^{x}  

where  

V is the depreciated value  

P is the original value  

r is the rate of depreciation  in decimal  

x  is Number of Time Periods  

in this problem we have  

P=\$15,500\\r=7.5\%=0.075\\x=6\ years

substitute

V=\$15,500(1-0.075)^{6}=\$9,709.17
