Integers can be whole numbers
Let the third side be x :
( 3√5 )^2 = 6^2 + x^2
45 = 36 + x^2
x^2 = 45 - 36
x^2 = 9
x = 3
Answer:
good
Step-by-step explanation:
<h2>
Answer:</h2>
<em>The course costs, approximately, </em><u><em>$0.16 per hour</em></u><em>.</em>
<h2>
Step-by-step explanation:</h2>
<h3>1. Convert the 10 weeks to hours.</h3>
10 weeks * 7= 70 days
70 days * 24= 1680 hours
<h3>2. Calculate cost/hour.</h3>
<em>Establish a rule of 3.</em>
<em>1680 hours -----> $275</em>
<em>1 hour -----> x</em>
<em>x= (1 hour * $275) / 1680 hours</em>
<em>x= 0.1636904762 ---> Round to the nearest cent.</em>
<em>x= 0.16 ---> Final result.</em>
