model aeroplane is made to a scale of 1 by two of the size of the real plane the area of the wings of the real plane are 40 m sq

4vir4ik [10]

The area of the wings of the model is 100000 square centimeters

<h3>How to determine the model area of the wings?</h3>

The given parameters are:

Scale factor, k = 1/2

Actual area of wings, A = 40 square meters

The model area is calculated as

Model area = Actual area * k^2

This gives

Model area = 40 * (1/2)^2

Evaluate

Model area = 10 square meters

Convert square meters to square centimeters

Model area = 10 * 10000 square centimeters

Evaluate

Model area = 100000 square centimeters

Hence, the area of the wings of the model is 100000 square centimeters

A truck company charged $40 for one day truck rental +0.85 per mile formulate a linear equation to model the cost c(d) Of one da

liubo4ka [24]

For this case we have to:

d: Let the variable representing the number of miles traveled per day

Then, the cost will be given by the following equation:

$C (d) = 0.85d + 40$

If we have the cost $C (d) = 91$ , then the number of miles traveled is:

$91 = 0.85d + 40\\91-40 = 0.85d\\51 = 0.85d\\d = \frac {51} {0.85}\\d = 60$

Thus, the number of miles traveled is 60.

Answer:

$C (d) = 0.85d + 40$

For a $C (d) = 91$ , the number of miles traveled is 60
