Determine the value of the variables when simplifying and evaluating the expression (302)0 . What is the value of m in the simpl
maria [59]
Answers:
___________________________
1)    302⁰ = 1 .
___________________________
2)         (302)⁰ = 30m ;   Solve for "m" ;

          →   Replace:  "(302)⁰ " ;  with "1" and rewrite:

          →   1 = 30m ;

     <span>     ↔</span>   30m = 1 ;

      → Divide EACH SIDE of the equation by "30" ; to isolate "m" on one side of the equation; and to solve for "m" ;

      →   30m / 30 = 1 / 30  ;

      →    m = 1/30 ;  or, write as:  0.303333333333333333....  ; 
           →  round to:  0.3033 .
________________________________________________
3)   Again: 

           →  (302)⁰ = 1 .

Juno ams Akima are training for a blathlon together. They are going to jog for the same amount of time as each other every day w
alexgriva [62]

Answer:3 hours

Step-by-step explanation:

Juno jogs at rate of 6 miles and bikes at rate of 14 miles covering total of 48 miles.

Akima jogs at rate of 8 miles and bikes at rate of 12 miles covering total of 44 miles.

Let jogging be represented by j

Let biking be represented by b

For Juno, 6j + 14b = 48 ......... i

For Akima, 8j + 12b = 44.......... ii

Multiply equation I by 8

Multiply equation ii by 6

48j + 112b = 384 ........... iii

48j + 72b = 264 ............. iv

Subtract equation iv from iii

48j + 112b = 384

- 48j + 72b = 264

40b = 120

b = 120/40

b = 3

Number of hours spent biking is 3 hours.
