18. A guy wire for a radio antenna tower runs from the ground diagonally to the top of the closest eye bolt to make a triangle. We can use the Pythagorean theorem to find the length of guy wire needed. The square of the distance between the wire on the ground and the eye bolt on the ground is 1,600 feet. The square of the height of the pylon is 6,400 feet. What is the length, c, of the guy wire

step-by-step explanation:

44

step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
