how do I solve the value of this​

The value of the given expression of subtraction 0.75–0.5, in simplest fractional form is 1/4.

Use the concept of subtraction defined as:

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

The given expression is:

0.75–0.5

After removing the decimal it can be written as,

75/100 - 5/10

Now simplifying it, we get

(75-50)/100 = 25/100

Now convert 25/100 in their simplest form:

Since 25x4 = 100

Therefore,

25/100 = 1/4

Hence,

The simplest fractional value of 0.75–0.5 is 1/4.

Thus the area of shaded region is 301.5 cm^2.

"The collection of all points equidistant from a fixed point in a plane is called a circle".

For the given situation,

The radius of the inner circle be r = 8 cm and

the radius of the outer circle be R = 16 cm

The formula to find area of the circle, [tex]A=\pi r^{2}[/tex]

Area of inner circle, [tex]A_{1} =\pi r^{2}[/tex]

⇒[tex]3.14[/tex] × [tex]8[/tex] × [tex]8[/tex]

⇒[tex]200.96[/tex]

≈[tex]201[/tex]

Area of outer circle, [tex]A_{2} =\pi R^{2}[/tex]

⇒[tex]3.14[/tex] × [tex]16[/tex] × [tex]16[/tex]

⇒[tex]803.84[/tex]

≈[tex]804[/tex]

The shaded region replicates the semicircle. So,

Area of the shaded region [tex]=\frac{A_{2} }{2} -\frac{A_{1} }{2}[/tex]

⇒[tex]\frac{804}{2} -\frac{201}{2}[/tex]

⇒[tex]402-100.5[/tex]

⇒[tex]301.5 cm^{2}[/tex]

Hence we can conclude that the area of shaded region is [tex]301.5 cm^{2}[/tex]

Answer:

about 21.9 ft²

Step-by-step explanation:

area of a half circle = [tex]\frac{\pi r ^{2} }{2}[/tex]

so [tex]\frac{\pi 3^{2} }{2} = 14.13716694[/tex] ft²

are of a square is [tex]bh\\[/tex]

so 6 x 6 = 36 ft²

so the area of the figure would equal the area of the square minus the area of the half-circle

36 ft² - 14.13716694 ft² = 21.86283306 ft² ≈ 21.9 ft²

Answer:

Assuming π is represented by 3.14, the correct answer is [tex]50.24m^2[/tex].

Step-by-step explanation:

Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is [tex]\pi r^2[/tex], where r is the radius of the circle. Since the radius of the shaded circle is [tex]4m[/tex], you can infer that the area of the shaded region would be [tex]4^2 * 3.14[/tex] = [tex]16*3.14[/tex] = [tex]50.24m^2[/tex].

To prove that EFGH is a parallelogram, the missing reasons are:

1. Alternate interior angles theorem

2. Reflexive property

3. SAS

4. CPCTC

5. Both pairs of quadrilateral EFGH are congruent, hence, EFGH is a parallelogram.

A parallelogram is a quadrilateral that has: two pairs of opposite sides that are parallel and congruent

To prove that EFGH is a parallelogram, we have the following proof which consists of the reasons that jsutifes each given statement:

1. ∠FGE and ∠HEG are alternate interior angles, therefore, ∠FGE ≅ ∠HEG based on the alternate interior angles theorem.

2. EG ≅ EG based on the reflexive property of congruence.

3. ΔFGE and ΔHEG have:

two pairs of corresponding congruent sides - EG ≅ EG, and FG ≅ EH

one pair of included congruent angles - ∠FGE ≅ ∠HEG

Therefore, ΔFGE ≅ ΔHEG by SAS.

4. Since ΔFGE ≅ ΔHEG, therefore, FE ≅ HG by CPCTC.

5. In conclusion, since both pairs of quadrilateral EFGH are congruent, then EFGH is a parallelogram.

Answer:

The equation to find [tex]x[/tex] is [tex](5\cdot x - 2)^{\circ} + (2\cdot x -2)^{\circ} + x^{\circ} = 180^{\circ}[/tex].

The degree measure of each angle is: [tex]m\angle J = 113^{\circ}[/tex], [tex]m\angle K = 44^{\circ}[/tex] and [tex]m\angle L = 23^{\circ}[/tex].

Step-by-step explanation:

From Euclidean Geometry we remember that the sum of internal angles in triangles equals 180°. If we know that [tex]m\angle J = (5\cdot x -2)^{\circ}[/tex], [tex]m \angle K = (2\cdot x - 2)^{\circ}[/tex] and [tex]m\angle L = x^{\circ}[/tex], then we construct the following equation of the triangle JKL in function of [tex]x[/tex]:

[tex]m\angle J + m\angle K + m\angle L = 180^{\circ}[/tex] (1)

[tex](5\cdot x - 2)^{\circ} + (2\cdot x -2)^{\circ} + x^{\circ} = 180^{\circ}[/tex]

[tex]8\cdot x -4 = 180^{\circ}[/tex]

[tex]8\cdot x = 184[/tex]

[tex]x = 23[/tex]

Finally, the measure of each angle is, respectively:

[tex]m\angle J = (5\cdot x -2)^{\circ}[/tex]

[tex]m\angle J = 113^{\circ}[/tex]

[tex]m \angle K = (2\cdot x - 2)^{\circ}[/tex]

[tex]m\angle K = 44^{\circ}[/tex]

[tex]m\angle L = x^{\circ}[/tex]

[tex]m\angle L = 23^{\circ}[/tex]
