Jay spent 3/8ths of his life working for a company, if jay has been working for his current company for 15 years, how old is he ?

answer:

40

step-by-step explanation:

if 3/8 equals 15 that means 1/8 equals 5 because 15/3=5. now if we multiply 5 by 8 then we get 40 years

answer:

$3.82

step-by-step explanation:

400/10=40

40 cents.

4.00-0.40=3.60

6 percent of 3.60 is 21.6

360+21.6=381.6

rounded=382

3.82

answer:

a(p(t))     =113.04 t^2

a (p(8))   =7234.56

step-by-step explanation:

p(t) = 6t

a (p) = 3.14 p^2

so a(p(t)) = means we   put p(t) in the function for a

                = 3.14 p^2

                = 3.14 (6t) ^2

                  = 3.14 (36t^2)

    a(p(t))     =113.04 t^2

let t=8    

a (p(8)) = 113.04 (8)^2

            = 113.04(64)

              =7234.56
