Chapter 2: Problem 90

A scale model of a car is constructed so that its length, width, and height are each \(\frac{1}{10}\) the length, width, and height of the actual car. By how many times does the volume of the car exceed its scale model?

Short Answer

Expert verified
The volume of the car is 1000 times larger than its scale model.

Step by step solution

01

Calculation of scale factor

The problem imposes that each of the dimensions (length, width, height) of the car model are one tenth of the equivalent dimensions of the real car, implying the scale factor is 1 / 10 or 0.1
02

Understanding volume property

The volume of three-dimensional objects is a property which scales with the cube of the scale factor. This means that you need to cube the scaling factor to compare the volumes.
03

Compute the volume scale

We will now cubing the scale factor to find how many times the actual car's volume is larger than the model's volume: \((\frac{1}{10})^3 = \frac{1}{1000}\). This indicates that the volume of the real car is 1000 times larger than the model.

Write as an algebraic expression in which \(x\) represents the number: the quotient of 9 and a number, decreased by 4 times the number. (Section 1.1, Example 3)

Solve each inequality. $$2(x+3)>2 x+1$$

On two examinations, you have grades of 86 and 88 . There is an optional final examination, which counts as one grade. You decide to take the final in order to get a course grade of \(\mathrm{A}\), meaning a final average of at least 90 . a. What must you get on the final to earn an A in the course? b. By taking the final, if you do poorly, you might risk the \(B\) that you have in the course based on the first two exam grades. If your final average is less than \(80,\) you will lose your \(B\) in the course. Describe the grades on the final that will cause this to happen.

Is \(x-4 y=14\) a true statement for \(x=2\) and \(y=-3 ?\)
