Answer:
<em>Diameter= 11.27 feet</em>
Step-by-step explanation:
<em>Circle = 2πr</em>
<em>or, 11.27π = 2πr</em>
<em>or, 11.27π/2π = r</em>
<em>r = 5.635 ft</em>
<em>diameter = 2r</em>
<em>= 2 x 5.635</em>
<em>= 11.27 feet</em>

Answer:
x = 2
Step-by-step explanation:
From the question we are given the algebraic sign with the Inequality sign
95 - 2x < 7 (15x - 17)
In order to find all the possible values of x that makes the algebraic expression true ,
We solve for this by convert the less than(<) sign to =
A true statement or algebraic expression is when both values on the left hand side and right hand side of and algebraic expression is the same of equal to each other.
Therefore:
95 - 2x = 7 (15x - 17)
95 - 2x = 105x - 119
Collect like terms
95 + 119 = 105x + 2x
214 = 107x
x = 214/107
x = 2
In other to confirm if x = 2 makes the expression true
95 - 2x = 7 (15x - 17)
95 - 2x = 105x - 119
95 - 2 × 2 = 105 × 2 - 119
95 - 4 = 210 - 119
91 = 91
Therefore, the possible values for x that make the statement true is x = 2

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>
