Question

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

Answer 1

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

Answer: ======> 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

Answer: ======> 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

Hope that helps!!! : )
