Hope it helps.
Answer:
23 or more chairs.
Step-by-step explanation:
There are 5 tables to start. Each tables is 450 dollars.
5x450=2250
4500-2250=2250
2250(money still need to be made) divided by 100(the price of a chair)=22.5
Since you can't have a half of a chair but you cant have any less, you round it up to 23 chairs. The answer is 23 or more chairs.
I dont know what the images are but scale factor is <span>is a number which </span>scales<span>, or multiplies, some quantity. Technically it is the number you have to multiply on each side that will get you the sides on the smaller or larger rectangle!!!
I hope it helps!!!

.we can call segment "a" the radius, and if we do that, we calculate the area of the triangle as follows:
Look at the vertical line bisecting the triangle, made up of segments of length "a" and "h"
Now look at the smaller, right triangle towards the bottom left of the equilateral triangle, with sides "a", "h", and "S/2".
If we're taking "a" to be the radius (in our case 6 inches), then
h
a
=
sin
30
degrees, so
h
6
=
0.5
, so h = 3 inches. Therefore the height of the equilateral triangle is
6
+
3
=
9
inches.
The original equilateral triangle in the figure is bisected by the vertical line, making 2 right triangles of height 9 inches and a base of length S/2.
S
2
a
=
cos
30
, so
S
2
=
0.866
⋅
6
=
5.196
inches (rounding).
So, the original equilateral triangle in the figure is twice the area of this larger right triangle. A right triangle's area is
1
2
b
⋅
h
. We have TWO of them, so the total area is
2
⋅

b
⋅
h
=
5.196
⋅

...which works out to:
46.77 square inches (rounding)
GOOD LUCK
