birr 300 is invested at 6% simple interest per annum. how long will it take for the interest to amount birr 180?​

10 years

Step-by-step explanation:

We are to calculate the Time(T)

The formula for Simple Interest is given as:

I = PRT

I = Interest = birr 180

P = Principal = birr 300

R = Interest rate = 6%

T = Time in years =??

T = I/ PR

T = 180/300 × 6%

T = 180/300 × 0.06

T = 180/18

T = 10 years

Therefore, it will take 10 years for the interest to amount to birr 180

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

answer: 5
