Answer:
4/12 = 1/3
8/12 = 2/3
Step-by-step explanation:
answer 1: 12 divided by 3 equals 4
answer 2: that number (4) multiplied by 2 equals 8
therefore four twelfths equal one third and eight twelfths equal two thirds
The 23 <em>exterior</em> angles add to 360. The interior angles are supplements of the exterior angles.
180 - 360/23 = 3780 / 23 = 164.3478...
Answer: a
f(x)=(x+4) ^2 −25
to solve set equal to zero
0 =(x+4) ^2 −25
add 25 to each side
25 = (x+4) ^2
take the square root of each side
square root (25) =(x+4)
+- 5 = (x+4)
5 = x+4 -5 = x+4
subtract 4 from each side
1 =x -9 =x
We already know that the box has an area of 100 sq. inches. All we have to do now is subtract the area of the 4 circles from the area of the box.
The formula for a circle's area is 
. We already know the radius, so one circle has an area of 12.56 units (4π in terms of pi). There are 4 circles, making your final equation 
.
