Answer: 5.6 N/cm^2
============================================
Work Shown:
Pressure = (Force)/(Area)
P = F/A
P = (84 N)/(15 cm^2)
P = (84/15) (N/cm^2)
P = 5.6 N/cm^2
For every square cm, 5.6 newtons of force is applied.
-------------
Extra info:
If you wanted to convert this to pascals, then you would need to convert 15 cm^2 to 0.0015 square meters. Then apply the formula above to get 56,000 pascals. 1 pascal is equivalent to 1 N/m^2.
If pounds was x
a. 0.65x is the equation.
2 pounds would cost $1.30
b. 0.65x-0.05x is the equation.
Answer:
A
Step-by-step explanation:
To convert mixed number as improper fractions, use this rule:

<u>For Juan:</u> (
)

<u>For Antonio:</u> (
)

Answer choice A is correct.
So 280=1.4x so 280/1.4 is 200 .7*200 is 140 so $140
