ABCD∼EFGH AD=45 in. , EH=75 in. , and AB=30 in. What is EF ? Enter your answer in the box. EF = in.
Helen [10]
The ~ symbol means that the 2 shapes are similar, meaning the same shape but not the same size.

To determine the measure of side length EF, you must find the relationship between the 2 side lengths.

You should set these up as ratios of the length to the width. So, for ABCD, it is 30/45. Make this equal to x/75. If you simplify the first ratio to 2:3, you can then multiply by both numerator and denominator by 25 to get x = 25 in/ 75 in.

Another way is to use cross products with you proportion. 75 x 30 = 45x. Solve for x to get 50 inches.

A company pays its commercial agents 5% of any deal. What should the value of a deal be for the agent to earn $2000?
Nataly_w [17]
The value of the deal should be $40,000.


remember that 5% as a decimal is .05.Let x = value of deal
The equation would be .05x = $2000 
Divide both sides by 0.05.
x=40,000
