Holly can make 60 necklaces.
Edit: I read the problem wrong, check the other comment.
Answer:
pi or 1 pi
Step-by-step explanation:
Area = 1/4 * pi * r^2 (because it is 1/4 of a full circle)
1/4 * pi * 2^2 (the radius is 2 because it is given in the picture)
1/4 * pi * 4 = 1 pi
area = pi
hope this helps! <3
Answer:
16
Step-by-step explanation:
Step 1) Multiple 7 by w, which w is 10. So, you do 7 x 10.
Now, you should have 70 - 54.
Step 2) Do 70 - 54.
Your answer should be 16.
Hope this helps,

Answer:
The demonstration is showed below
Step-by-step explanation:
The distance betwenn two points is given by:
If the point is equidistant from a point and a line, the distance must be equal. For the line let's select the point (x,-4), because the distance will be ortogonal, and is the small distance between a point and a line. So:
Removing the squares:
(x-2)² + y² = (y+4)²
(x-2)² + y² = y² + 8y + 16
y² - y² - 8y = 16 - (x-2)²
8y = (x-2)² - 16
y = (1/8)*(x-2)² - 16/8
y = (1/8)*(x-2)² - 2
The first one sorry if wrong
