A study show that there are 16 vehicles for every 10 households how many vehicles are there for 107 million households

1 answer:

6 0

$\bf \begin{array}{ccll}
vehicles&households\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
16&10\\
v&107E6
\end{array}\implies \cfrac{16}{v}=\cfrac{10}{17E6}\implies \cfrac{17E6\cdot 16}{10}=v$

just to clarify the engineering notation, E6 is just 1 and 6 zeros, or a million, thus, 107,000,000 is just 107E6.

Use intercepts to graph the line described by each equation. -6y=-4x+24

Aloiza [94]

First, you have to get the equation to the normal form of a line. To do this, you divide both sides by -6 to get $\frac{2}{3} x-4$ . The y-intercept is at -4 and your slope is 2/3. Use this to graph the equation.

The area of a square mat is 125 square inches. The best approximation of its length is inches. If the length of each side is inc

gtnhenbr [62]

The area of a square is simply the side length squared and we are given that the area is 125 so:

s^2=125

s=√125

s=5√5

Now using the area equation again, and adding 1 inch to s we have:

A=(s+1)^2, and using s found above we have:

A=(5√5+1)^2

A=125+10√5+1

A=126+10√5 in^2

A≈148.36 in^2 (to nearest hundredth of a square inch)

An image of a book shown on a website is 3 inches wide and 4.5 inches tall on a computer monitor. The actual book is 9 inches wi

Drupady [299]

Answer:

It Depends

Step-by-step explanation:

If the image is the scale, the answer is 1/3, since its width of 3 is 1/3 the width of the actual book.

If the book is the scale, the answer is 3, since its width of 9 is 3 times the width of the image.
