Given that,
In the picture, there is a square and a shaded region inside the square.
We have to find the shaded portion area.
The side of the square is 8cm.
Now,
First we see the unshaded region on the square is there are 4 unshaded regions.
In the figure u can see there is a unshaded region we named that has tile 1, tile2, tile 3, and tile 4.
If we restock them we can see that we got a circle with that 4 tiles.
Now, the side is 8 cm then the 1 tile will be of 4 cm.
So, the radius of the circle is 4 cm.
In the other picture we can see that the area of the shaded region is equal to area of square- area of circle.
Area of the shaded region =s²-πr²
Area of the shaded region =8²-π(4)²
Area of the shaded region =64-π(16)
Area of the shaded region =64-16π
Area of the shaded region =64-16(3.14)
Area of the shaded region =64-50.24
Area of the shaded region =13.76
Therefore, The shaded portion has a 13.76 square metre area.

Hence proved that triangle AB = 3(3) - 1 = 9 - 1 = 8.
What is triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the display style for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except when otherwise specified, this article discusses triangles in Euclidean geometry, namely the Euclidean plane.
Given that,
AB + AC = AC
3y - 1 + 7y = 29
10y = 29 + 1 = 30
y = 30/10 = 3
Therefore, AB = 3(3) - 1 = 9 - 1 = 8.

What are the diameter and the radius of a circle?The radius of a circle is given by the length of the line segment from the center of the circle towards an edge of the circle.The diameter of a circle is given by the length of the segment between two opposite edges of the circle, passing through the center, hence it is twice the radius.In the context of the circle given in this problem, we have that:
The center is of A.The radius is of AD.The diameter is of EF.hence:

the sum of simple interest and compound interest of a certain interest on a sum of money for 2 years at the rate of 7% p.a is Rs 85470. by how much percent the compound interest is more than the simple interest?
Answers
Answer: 3.3%
Step-by-step explanation:
Principal not given.
SI = PRT/100
CI = P(1+R/100)^T -
SI + CI = 85470
[P×7×2]//100 + P [1+ (7/100)]^2 = 85470
on solving: P = 3,00,000
P = 300000 SI for 2 years = 42000
CI = Rs 43470
The difference= Rs 1470

Slope of AB = 2; Slope of DC = 2

Both pairs of opposite sides are parallel because they have the same slope, therefore, quadrilateral ABCD is a parallelogram.
What is a Parallelogram?A parallelogram is a quadrilateral that has two pairs of opposite sides that have the same lengths and are parallel to each other.
Since the opposite sides of a parallelogram are parallel, therefore, they have the same slope value.
Slope = change in y / change in x.
Find the slope of AB and DC. then AD and BC:
Slope of AB = (-2 - 2)/(-3 -(-1)) = -4/-2
Slope of AB = 2
Slope of DC = (-3 - 1)/(-1 - 1) = -4/-2
Slope of DC = 2
Slope of AD = (-3 -(-2))/(-1 -(-3)) = -1/2
Slope of AD = -1/2
Slope of BC = (2 - 1)/(-1 - 1) = 1/-2
Slope of BC = -1/2
Therefore, since AB and DC have the same slope, they are parallel, so also is AD and BC parallel because they have the same slope, therefore, quadrilateral ABCD is a parallelogram.

Kevin has x dollars in an account that pays 2.2% interest, compounds quarterly. Express his balance after one quarter algebraically
Answers
Balance of Kevin after 1 quarter will be 1.0055(x)
What is quarterly compounded compound interest?Compound interest is interest that is calculated using both the starting amount and the interest that has accrued over time.
Interest is considered to be compounded quarterly if it is compounded four times each year.
If interest is compounded four times or quarterly each year, the formula for the amount at time t is as follows.
A = P( ( 1 + (r/4))⁴ⁿ
A = Accumulated amount
P= Principal amount
r = interest rate
n = time
Given that Kevin has x dollars in an account that pays 2.2% interest, compounds quarterly
∴ P = x
r = 2.2% = 2.2/100
To find balance after one quarter , i.e. time n = 1/4 year
⇒ Balance = accumulated amount =$ x(1 + 2.2/400)¹ = $ 1.0055(x)
Therefore, Balance of Kevin after 1 quarter will be 1.0055(x)

Answer: G=62, I = 62, H =54
Step-by-step explanation:
3x+26=4x+14
x=12
G=36+26 = 62
180-62-62=54
We know that
G= (3x+26)°
I= (4x+14)°
Since G°=I°,
4x+14=3x+26
4x-3x=26-14
X= 12
Now, angle G=(3x+26)°
Since X=12,
G= (3(12)+26)°
G=62°
Since G=I, I would also be 62°
We know that all angles in a triangle must add up to 180°,
Therefore
angle H = 180-(2(62))
H= 180-124
H = 56°
And therefore we know that
Angle G = angle I = 62°
Angle H = 180-(Angle G + Angle I) = 56°

A triangle has three sides: AB, BC, CA. We know that angle A is greater than angle C. Find the range for side AC.
A) AB< CA< BC
B) BC- AB < CA < AB + BC
C) BC< CA< AB
D) AB + BC < CA < BC- AB
Answers
Answer:
BC- AB < CA < AB + BC
Step-by-step explanation:
The sides opposite the larger angles are longer than the sides opposite smaller angles.
So, BC (opposite < A) is longer than AB (opposite < C) so,
BC > AB
The other side AC cannot be greater than AB + BC, otherwise the triangle would not exist, so,
AC < AB + BC
Also, CA > BC - AB
