A. t=13 B. K= 23 C. t= 1 3/8

Step-by-step explanation:

A. 2t-30m=20

30 x 1/5= 6

2t-6+6=20+6

2t/2=26/2

t=13

B. 14+m=2k

14+12=2k

14+12=46

46/2=23

k=23

C. 1/8r+t=1

1/8 x (-3)= -3/8

1 - (-3/8)= 1 3/8

t= 1 3/8

Hope it helps!

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
