1. use the formula p = 2l + 2w to find l if p = 48 feet and w = 6 feet. p = 2l + 2w p = 2(48) + 2(6) p = 96 + 12 p = 108 feet true false 2. stress on a suspension cable on a bridge can be estimated using s = 7.2(weight)2 + 3480. find the stress if the weight is 8 tons. a. 3537.6 pascals b. 6797.76 pascals c. 3595.20 pascals d. 3940.8 pascals 3. find the sales revenue from selling 175 coffees at $3.25 each. round to the nearest cent if necessary. a. $0.02 b. $53.85 c. $568.75 d. $56,875

3):   3.25  Multiply by 175  >  $568.75, Letter Choice, (C), is your final answer.

                            (3.25)(175)

>      Answer  568.75,   Letter Choice, (C).      

1):   Let's solve your equation step-by-step.

p     =      (2)(48)     +      (2)(6)

Step 1: Simplify both sides of the equation.

p      =      (2)(48)     +      (2)(6)

p       =     96     +     12

p      =     (96      +     12)       (Combine Like Terms)

p      =       108

p      =      108

    >    p     =     108,   Your Answer would be TRUE

2):    Modulus / Stress: N/mm2 ( =  MPa)

Equation:   ===>   S   =   7.2(8)2  + 3480

Let's solve your equation step-by-step.

s     =      (7.2)(8)(2)     +     3480

Step 1: Simplify both sides of the equation.

s      =      (7.2)(8)(2)      +      3480

s      =       115.2      +      3480

s       =       (115.2       +   3480)         (Combine Like Terms)

s      =       3595.20

s       =       3595.20  

   >   S     =    3595.20   Pascals Letter Choice, (C); is your answer.

Answers:

1):   TRUE  >   P   >   108

2):  Letter Choice, (C);  S    >  3595.20  PASCALS

3):    Letter Choice, (C);   $568.75
