Answer:
P = 321.3m
Step-by-step explanation:
To help simplify the process of solving this problem, first break it up into different shapes. Here, you have two shapes: a rectangle and a circle (1 semi-circle + 1 semi-circle = 1 circle).
Next, use the equation for circumference of a circle to find the first part of the perimeter (C = πd). In this case, the diameter would be 45m.
- C = πd
- C = 3.14 × 45
- C = 141.3 m
This is the first part of the circumference. Now, you must consider the rectangle. (Because the two shorter sides of the rectangle are not part of the perimeter, do not include these in your final answer.) The length of the rectangle is 90 meters, and since both sides that measure to 90m are part of what makes up the perimeter, lastly add these to the circumference you calculated earlier.
- (90 + 90) or (90 × 2) = 180
- P = 141.3 + 180
- P = 321.3m

Answer:
y=41
Step-by-step explanation:
Let us start by writing an equation. <em>4 plus y divided by 5 equals to 9</em> :
Great! Now let us solve for the variable, <em>y</em>, by isolating the terms:
<em>I hope this helps! Let me know if you have any questions :)</em>
I don't think you need to do anything special for this question. But do be careful how you read it.
Total number of instruments = 63
Number of woodwinds = 21
Number of non woodwinds = 63 - 21 = 42 non woodwinds.
What you have to be careful about is that this is not the answer.
It says how many more .... So now you have to do another subtraction.
Total number more = Number of non woodwinds - woodwinds.
Total number more = 42 - 21
Total number more = 21 <<<< Answer
