Let 32% of x = 56
32%*x = 56
32/100 *x = 56
x = 56*100/32
x = 5600/32 = 175
hence, 32% of 175 is 56.
A polygon inscribed in a circle, luckily, has a derived formula already. It is:
A = (nr²/2)[sin (360/n)]
where n is the number of sides of the polygon and r is the radius of the circle. For this problem, n = 100 and r = 1. Substituting this to the equation,
A = (100(1)²/2)[sin (360/100)]
A = 3.14 square units
Thus, the 100-gon has an area of 3.14 square units.
Answer:
4/15xy
step-by-step explanation:
2(1/3x) (2/5y)
= 2/3x × (2/5)y
= 2×2
xy
3×5
= 4/15xy
Hope this answer helps you :)

Answer:
B. 15.4 ft
Step-by-step explanation:
this answer, without any formulas used, can be answered correctly and logically.
answer c, d and e are eliminated as the opposite side cant be greater than the hypotenuse.
now we have to find which is correct between a and b
the answer will be 'B' as the value of sine of an angle keeps increasing as the angle itself increases. thus, giving a bigger value of the opposite side (required height). as 15.4 ft.
mathematically,
sin65° = x/17
17 × sin65° = x
where x is height of the side of the building.

Answer:
(2x +y)(2x -y +6)
Step-by-step explanation:
The shaded area is the difference of the areas of the outer square and the inner square. In turn, those areas are the square of the edge dimension of the square. So, the shaded area is the difference of squares:
area = (2x +3)² -(y -3)²
The difference of squares is a "special product" in that it has a factored form that is worth remembering.
a² -b² = (a -b)(a +b)
Using this form for our area, we have ...
area = ((2x +3) -(y -3))((2x +3) +(y -3))
area = (2x -y +6)(2x +y)
