What is the solution to the equation (2 – 2) + 22 – 4 = 9?

Answer:

Model B has 6 shaded sections

Step-by-step explanation:

The question is not complete. The complete question should be in the form:

Victor has 2 fraction models. Each is divided into equal sized sections the models are shaded to represent the same fraction. Model A is divided into 6 sections and 3 sections are shaded. Model B is divided into 12 sections. What do you know about the number of sections shaded in Model B? Explain your answer.

Solution:

The fraction modeled by model A is given by the ratio of shaded sections to  the total number of sections.

That is Fraction of model A = number of shaded sections / total number of sections.

Hence:

Fraction of model A = 3 / 6

Since model B and Model A are equivalent, the number of shaded sections in Model A is given by:

number of shaded sections in model B/ total number of sections in model B =  Fraction of model A

number of shaded sections in model B / 12 = 3 / 6

number of shaded sections in model B = 12 * 3/6

number of shaded sections in model B = 6

Answer:

1.48 m

Step-by-step explanation:

In a class of 32 students

the mean height of the 14 boys is 1.56 meters.

the mean height of all 32 students is 1.515 meters.

Total number of students = 32

Mean height of all students = 1.515

We can obtain the sum of all student's height :

Number if students * mean height

= 32 * 1.515

= 48.48

Number of boys = 14

Mean height of boys = 1.56m

We can obtain the sum of all boys height :

Number if students * mean height

= 14 * 1.56

= 21.84

Number of girls :

All students - Number of boys

32 - 14 = 18

Sum of girls height :

48.48 - 21.84 = 26.64

Mean height of girls :

Sum of girls height / Number of girls

26.64 / 18

= 1.48 m

Answer:

SinA=3/5

CosA=4/5

TanA=3/4

Step-by-step explanation:

first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2

20^2-16^2=144 the square root of 144 is 12 so side length bc=12

so sin is opposite/hypotenuse

the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5

cos is adjacent/hypotenuse

the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5

tan is the opposite/adjacent

the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4

Answer:  (2,3)

====================================================

Explanation:

The intersection point of the two lines is where the solution point is located.

The x coordinate of that intersection point is a bit smaller than x = 2, but when rounded to the nearest whole number, we would get to x = 2.

At the same time, the y coordinate of the intersection point is a bit above y = 3, which rounds to this value when rounding to the nearest whole number.

So that's how we get to (2,3)

Answer:

D

Step-by-step explanation:

x+17 = 4x-34

-3x = -51

x = 17

17+17= 34

The bottom two are equal so 34, 34

A triangle adds up to 180

180- 68 = 112

So the top is 112

After solving the equation for all three angles of a triangle, the angles are 34, 112, and 34. Hence, option C is correct.

The basic polygonal shape of a triangle has three sides and three interior angles. It is one of the elementary objects in geometry and is represented as follows. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given angles of a triangle in the question,

Let angle A = 6x + 10  (i)

Angle B = x + 17 and,   (ii)

Angle C = 4x - 34  (iii)

The submission of all angles will be equal to 180°.

(6x + 10) + x + 17 + 4x - 34 = 180

11x = 187

x = 17

Substitute the value of x in equations to find the angle,

A = 6(17) + 10 = 112

B = 17 + 17 = 34

C = 4(17) - 34 = 34.

These are the angles obtained

An angle is a figure created by two rays. The value of x is 10 units.

An angle is a figure created by two rays, known as the sides of the angle, that have a common terminus, known as the vertex of the angle.

The line VT bisects ∠STU, therefore, the two triangles will be similar because VT is the common line between the two triangles while ∠STV and ∠UTV are equal angles. Therefore, we can write,

[tex]\dfrac{UT}{UV} = \dfrac{ST}{SV}\\\\\dfrac{3x+2}{24} = \dfrac{12}{9}\\\\3x+2 = \dfrac{12 \times 24}{9}\\\\\\3x+2=32\\\\x=10[/tex]

Hence, the value of x is 10 units.
