Answer:
the option are A.
92.4%
B.
7.6%
C.
91.8%
D.
8.2%
Step-by-step explanation:
Think of it what times 61 will equal 66....
61 () = 66
(?%) = 66 /61
(?) = 1.08196
so now it gets tricky get the percentage increase correct
based on the given answer choices I'ld say it is D
% increase = (1.08196 - 1) (100) Why the subtraction of one? ?
= 8.196%
= 8.2 %

Answer:
6x-18
Step-by-step explanation:
First we multiply everything in the parentheses by 3
3×2x=6x
3×(-6)=-18
And now we put it together-
6x-18
Answer:
x = 3 and y = 2
Step-by-step explanation:
For the triangles to be congruent.
The hypotenuse and a leg of one triangle and the hypotenuse and a corresponding leg of the other triangle must be congruent, that is
x = y + 1 → (1) congruent legs
3y = x + 3 → (2) congruent hypotenuse
Substitute x = y + 1 into (2)
3y = y + 1 + 3, that is
3y = y + 4 ( subtract y from both sides )
2y = 4 ( divide both sides by 2 )
y = 2
Substitute y = 2 into (1)
x = 2 + 1 = 3
Answer:

Step-by-step explanation:
1. Approach
The easiest way to solve this problem is to find the area of the triangle and the area of the inscribed circle. Then subtract the area of the inscribed circle from the area of the triangle.
2. Find the area of the triangle,
The area of the triangle can be found using the following formula,

Where (b) represents the base of the triangle, and (h) represents the height.
Substitute in the given values and solve,

3. Find the area of the inscribed circle,
The formula to find the area of a circle is the following,

Where (pi) represents the numerical value (3.1415...) and (r) represents the radius of the circle. By its definition, the radius of a circle is always half of the diameter, thus the radius of the given circle is (3).
Substitute in the given values and solve,

4. Find the area of the shaded region,
To accomplish this task, subtract the area of the circle from the area of the triangle,
