A semicircle's perimeter is half the perimeter of the complete circle.
The perimeter of the complete circle is its circumference which is found by the equation: πD.
Then the equation of the perimeter of the semicircle is πD/2
In this case D = 24 in, then the perimeteir is π (24in/2) = 12π in ≈ 37.7 in
Answer: The exact length is 12π inches and the approximate length is 37.7 inches
Number of swings = x
Number of slides = y
First condition:
number of slides must be more than 3 times number of swings
This means that: y > 3x
Second condition:
each swing cost 275$ and each slide costs 168$. They cannot spend more than 1250$. This means that the sum of costs of swings and slides should not exceed 1250$ (should be less than or equal to 1250$)
This means that: <span>275x+168y ≤ 1250
Based on this:
The correct choices are: b and d</span>
<h3><u>
Answer:</u></h3>
- The equation is y = -x/2 - 3
<h3><u>
Step-by-step explanation:</u></h3>
<u>We know the equation.</u>
<u>We also know the y-intercept, which is -3.</u>
<u>All we need to find is the slope. Once the slope is found, our equation is set.</u>
- => Slope = Rise/Run
- => -1/2 = Slope
<h3><u>Conclusion:</u></h3>
<u>Since the slope has been found, </u><u>the equation is y = -x/2 - 3.</u>
