Answer: 97.7 in
Step-by-step explanation: The perimeter is another name for circumference. Since we know that the formula for circumference is 2(pi)r, but we only want half of that.
Note that 2r is another way of writing the diameter (d).
In this case, we can use the formula d(pi)/2 + d (we’re adding d because d(pi)/2 will only give us the perimeter of the arch.
38(pi)/2 = 59.66
59.66 + 38 = 97.66
Rounded, that would be 97.7 in

Step-by-step explanation:
<u>Step 1: Define Inequality</u>
3x + 1 < 10
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 1 on both sides: 3x < 9
- Divide 3 on both sides: x < 3
Here we see that any value <em>x</em> smaller than 3 would work as a solution to the inequality.
I think it's true because its the same data set just put in order backwards.
Hope this helps!! :-)
