Recall that 
Pressure = Force ÷ Area

In this context we have,
Pressure = 24,000 ÷ (16 × 12)
               = 24,000 ÷ 192
               = 125 Pa

Answer:

125 N/m^2

Step-by-step explanation:

To calculate the the pressure(P) we need area(A) and force(F) because pressure is a function of force and area:

P=F/A (N/m^2)

We can calculate the Area as:

A=16*12=192 m^2

Therefore we can calculate pressure per square meter:

P=24000*(192)=4608000 N/m^2

There are 2820 cars in Farmington. The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size ca
oee [108]

Answer:

Number of full size cars = 900

Step-by-step explanation:

The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size cars is 8 to 9. Since compact cars are  there in both ratios , we need to  make the number in the ratio for compact cars to be the same.

\frac{medium}{compact} = \frac{7}{5}

Multiply by 8 on numerator and denominator

\frac{medium}{compact} = \frac{56}{40}

\frac{compact}{full size} = \frac{8}{9}

Multiply numerator and denominator by 5.

\frac{compact}{full size} = \frac{40}{45}

Ratio of medium, compact and full size are in ratio 56,40,45.

Total number of cars =2820.

(56 + 40 + 45)x = 2820

x = \frac{2820}{141}

x = 20

Number of full size cars = 20\times 45 =900
