Answer:
A
Step-by-step explanation:
Hey There!
To find the amount of area she is painting we have to find the area of one side and multiply that by 4 ( because there are 4 walls)
8x10=80
80x32=320
so Betsy will be painting 320ft²
Answer:
4(2x-3)(2x+3)
Step-by-step explanation:
The first thing you would do is find the greatest common factor (the biggest number that goes into both of them.
Common factors
1,2,4
So the greatest common factor would be 4 so then you would divide both numbers by 4 and bring it to the outside like so.
4(4x2 - 9)
then you would take it out to where it would multiple to get the same number, like this.
4(2x-3)(2x+3)
Answer:
A = 81.681409 (81.64 for 3.14 as pi) B = 4.65222141 (4.65458109 as 3.14 for pi) rotations
Step-by-step explanation:
To figure out how far one full rotation is (which is the circumference) you do the circumference formula: C = 2 pi r
C = 2 pi 13
C = 26pi
C = 81.681409
To figure out how many rotations C can fit into 380, divide 380 by C
380 / 81.681409 = 4.65222141
Answer: 5/10 or 1/2
Step-by-step explanation:
They are because if two angles that have a side of one triangle that is congruent to the corresponding parts of another triangle, the triangles are congruent to the corresponding altitudes in triangles.
