Answer:

  3) ? = 21

  4) ? = 6

Step-by-step explanation:

3) The given ratio is ...

  A : B = 2 : 7

You want to find ? such that ...

  2 : 7 = 6 : ?

The ratio is equivalent when both numbers are multiplied by the same value.

From your knowledge of multiplication tables, you know that 2×3 = 6. then 7×3 = ? = 21.

__

4) For this one, you need to recognize that the given number corresponds to B.

  A : B = 2 : 3

  2 : 3 = ? : 9

Again, you know that 3×3 = 9, so 3×2 = ? = 6.

Given:

Two secants intersecting each other outside the side the circle.

To find:

The value of x.

Solution:

Using Intersecting Secant Theorem, we get

[tex]x(x+8)=4(4+8)[/tex]

[tex]x^2+8x=4(12)[/tex]

[tex]x^2+8x=48[/tex]

[tex]x^2+8x-48=0[/tex]

Using splitting the middle terms, we get

[tex]x^2+12x-4x-48=0[/tex]

[tex]x(x+12)-4(x+12)=0[/tex]

[tex](x+12)(x-4)=0[/tex]

Using zero product property, we get

[tex](x+12)=0\text{ and }(x-4)=0[/tex]

[tex]x=-12\text{ and }x=4[/tex]

Side length cannot be negative, i.e., [tex]x\neq -12[/tex].

Therefore, the only value of x is 4.

The whole question didn’t fit so it said “ determine if it can be proven that the triangles are congruent. If they are congruent select the theorem that proves they are congruent”

Answers

The triangles are congruent. The theorem that proves this is SAS, which stands for side and side. As seen in the picture the red marks indicate that these triangles have two congruent sides. And from how they’re connected at the angles, we also see they have congruent angles. Therefore the answer is SAS Theorem.

Which statement is true about the solution to the system of equations below? { 2 y = 2 x + 2 4 y = 4 x + 10

Answers

Step-by-step explanation:

Given equations are :

2y = 2x + 2 ....(1)

4y = 4x + 10 ....(2)

we need to find the solution of the system of equations.

If the general equation are :

a₁x+b₁y+c₁ = 0

and

a₂x+b₂y+c₂ = 0

[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\ne \dfrac{c_1}{c_2}[/tex] (For parallel lines)

Here, a₁ = 2, b₁ = 2, c₁ = 2, a₂ = 4, b₂ = 4 and c₂ = 10

Since, [tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{2}{4}\ne \dfrac{c_1}{c_2}[/tex]

Hence, the given system of equation is parallel lines.

Find the area of the
regular figure below:

A) 2,338.3 cm
B) 2.225.8 cm2
C) 2.190.1 cm2
D) 2,458.5 cm
E) 2,603.2 cm2

Answers

Answer:

Option A: 2338.3 cm² is the correct answer.

Step-by-step explanation:

Given that:

The given figure is a regular hexagon.

Length of side = 30 cm

Area of a hexagon is given by;

Area = [tex]\frac{3\sqrt{3}}{2}a^2[/tex]

Putting a=30 in the formula

Area = [tex]\frac{3\sqrt{3}}{2}(30)^2[/tex]

Area = [tex]\frac{3\sqrt{3}}{2}*900[/tex]

Area = [tex]3\sqrt{3}*450[/tex]

Area = 2338.26 cm²

Rounding off to one decimal place,

Area = 2338.3 cm²

Hence,

Option A: 2338.3 cm² is the correct answer.
