Hi there!
Since we know that half of the circle is 180 degrees, we start with that. Then, we need to add 40 degrees because of arc DCE. So, the measure of major arc ABD is 220 degrees.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
For this question, just multiply the number (300) by the percent (.95)
Your answer is 285 women

Answer:
There is obviously only 1 10x10 square. If we start with a 9x9 square in the top left corner, we can move it down 1, across 1 and back up 1, so there are 4 possible 9x9 squares.
For 8x8 we can move down 1, then 2 and we can move across 1 or 2 so that's 9 possible 8x8 squares.
For 7x7 we can go down 3 and across 3, so that's 4x4=16 possible squares.
The pattern is now clear the total number if squares is 1+4+9+16+…+100.
There's a formula for this, which I had to look up, but any the sum of the first n squared is 1/6n(n+1)(2n+1)1/6n(n+1)(2n+1), so the total number of squares is 10x11x21/6=5x11x7=385.
Negative number because of minus sign next to it
