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

In 2010 the population of Brazil was about 1.907×10 to the 8 power. The population of Mexico is about 1.123×10 to the 8 power. A
Romashka [77]

Brazil population: 1.907×10^{8}

Mexico population 1.123×10^{8}

To find how much more the population was in Brazil than in mexico, you would subtract the Brazil population to Mexico's population:

The 10^{8}'s would not cancel out because they are representing further decimal places that aren't written, so you would subtract 1.907 and 1.123.

1.907 - 1.123= 0.78410^{8}

Brazil's population is 0.784×10^{8} larger than Mexico.
