The rate is given as a percent (%). Before using it in the simple interest formula, you must first convert it to a______.

Back

decimal

Back

slope

Front

If the principal amount is $3000, the interest rate is 5%, and the time period is 4 years, what is the simple interest?

Back

$600

Front

Triangle HJK and triangle PMK are similar right triangles. The slope of HK is equal to the slope of PK because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for HK as it is for PK.

Back

True

Front

What is the formula for calculating simple interest?

Back

Simple Interest = Principal × Rate × Time

Front

How do you convert a fraction to a decimal?

Back

Divide the numerator by the denominator.

Front

What is the slope of a line?

Back

The slope is the ratio of the rise (change in y) over the run (change in x).

Front

If a line has a slope of 2, what does this mean?

Back

For every 2 units it rises, it moves 1 unit to the right.

Front

What is the relationship between similar triangles and their slopes?

Back

Similar triangles have proportional sides and equal slopes.
