Determine operating cost per mile. Choose the right answer.
SVETLANKA909090 [29]

Answer: $0.1428/mi or about 14 cents per mile

Steps:

While the cost of car = $5,000.00 is not an operating cost, the annual decrease of value is. So, given that the market value after 1 year = $3,800, the value loss is 5000-3800=$1200 for the year.

Add cost of gas and oil = $750.00, Repairs/Maintenance = $250.00, Insurance = $300.00, to get $2500 total operating cost.

The cost per mile is $2500/17500 miles = $0.1428/mi or about 14 cents per mile

What is the pressure difference Δp=pinside−poutside? Use 1.28 kg/m3 for the density of air. Treat the air as an ideal fluid obey
Sidana [21]

This is an incomplete question, here is a complete question.

A hurricane wind blows across a 7.00 m × 12.0 m flat roof at a speed of 150 km/h.

What is the pressure difference Δp = p(inside)-p(outside)? Use 1.28 kg/m³ for the density of air. Treat the air as an ideal fluid obeying Bernoulli's equation.

Answer : The pressure difference will be, 1.11\times 10^3Pa

Step-by-step explanation :

As we are given:

Speed = 150 km/h = 41.66 m/s

Density = \rho=1.28kg/m^3

Area = A = 7.00 m × 12.0 m

Formula used :

\Delta P=\frac{1}{2}\times \rho \times v^2

Now put all the given values in this formula, we get:

\Delta P=\frac{1}{2}\times (1.28kg/m^3)\times (41.66m/s)^2

\Delta P=1.11\times 10^3Pa

Thus, the pressure difference will be, 1.11\times 10^3Pa

Two less than the sum of twice a number and forty
DiKsa [7]

Answer: 2-(2x+40) or (2x+40)-2

Step-by-step explanation: If you wanted to solve the problem, you have to do the stuff in the parentheses before you do the stuff out of the parentheses. In the parentheses, you will have to solve 2x before you do anything else. When you solve 2x, the answer to that, add it to 40. Then the answer in the parentheses, subtract it by 2 and you can get the answer.
