1.) top row: 100 200 300 400 500 600. Bottom row: 5 10 15 20 25 30
2. Each ratio is just the top row divided by the bottom row. So the second thing in the ratio would be 200/10, the third one 300/15, etc. Each ratio is equal to 20.
3.) if x is gallons of gas used, y is distance driven. the equation that describes this relationship is y=20x.

What is 98.704 in expanded using powers of ten

Tomtit [17]

Answer:

$9.8704 * 10^1$

Step-by-step explanation:

The standard form is called the scientific notation expressed generally as;

$A * 10^n$

A is an integer between 1 and 10

n is ant integer or fraction

Given the decimal value 98.704, we ill shift the decimal point to the back once to have;

98.704 = $9.8704 * 10^1$

<u>Note the when the decimal point is shifted backwards the value of n is always positive</u>. Hence the expansion in power of 10 is $9.8704 * 10^1$
