Answer:

6

Step-by-step explanation:

-6 + (12)

○ First you remove the brackets

○ Then you will get -6 + 12

○ Negative Positive (-+) equals Negative

○ You will put will subtract the bigger number by the smaller number

i.e 12-6

○ You will get your answer as 6

Answer:

Step-by-step explanation:

7a + 33° = 10a - 12° ( being vertically opposite angle )

33° - 12° = 10a - 7a

21° = 3a

a = 21/3

a = 7°

Now,

6b - 42 = 3b ( vertically opposite angle )

6b - 3b = 42°

3b = 42°

b = 42/3

b = 14

hence , the value of a is 7°and b is 14°...

three-by-three systems:

In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables x,y,z

is called an ordered triple.

To find a solution, we can perform the following operations:

Interchange the order of any two equations.

Multiply both sides of an equation by a nonzero constant.

Add a nonzero multiple of one equation to another equation.

The cost of a job that takes 6 hours is $280.

Discount:

Discount, the term referred as the amount or percentage deducted from the normal selling price of something. The discount means a reduction in the price of a good or service.

Given,

A repair shop charges $50 per hour. this week it is offering a $20 discount. And it represents the equation as,

c = 50h-20

Where

c represents the total cost, and

h represents the hours taken.

Here we need to find the total cost of a job that takes 6 hours.

According to the given details we know that the value of h = 6.

Then we need to find the value of c,

So,

=> c = 50(6) - 20

=> c = 300 - 20

=> c = 280

Therefore, the total cost of a job that takes 6 hours is $280.

The unitary technique, in its most basic form, is used to calculate the value of a single unit from a specified multiple. How to determine the value of one pen, for instance, if the cost of 40 pens is Rs. 400. The unitary approach can be used to complete it. Additionally, after determining the value of a single unit, we can multiply that value by the number of units needed to determine the value of the additional units. The concept of ratio and proportion is mostly applied using this way.

The coordinates of the vertices of the triangle A'B'C' are (14, 3), (- 6, 2) and (- 8, 6), respectively. (Correct choices: A, E, D)

In this question we find the locations of the three vertices of the triangle, each of which has to be transformed by using a non-rigid transformation rule, that is, a transformation rule that does not conserve the original form of the triangle. We are asked to determine the possible coordinates associated with the triangle A'B'C.

If we know that A(x, y) = (7, 6), B(x, y) = (- 3, 5) and C(x, y) = (- 4, 9), then the coordinates of the vertices of the triangle A'B'C' are:

A'(x, y) = (2 · 7, 6 - 3)

A'(x, y) = (14, 3)

B'(x, y) = (2 · (- 3), 5 - 3)

B'(x, y) = (- 6, 2)

C'(x, y) = (2 · (- 4), 9 - 3)

C'(x, y) = (- 8, 6)

By solving a linear equation we can see that the value of x is 28, and with that, we can see that the measure of the left angle is 85 degrees, and the measure of the right angle is 50 degrees.

We know that the angle at vertex S measures 135°, then we can write the linear equation:

(3x + 1)° + (2x - 6)° = 135°

First, we need to solve this for x.

3x + 1 + 2x - 6 = 135

5x - 5 = 135

5x = 135 + 5 = 140

x = 140/5 = 28

Now that we know the value of x, we can find the two measures, which are:

QSR = (3x +1) = (3*28 + 1)° = 85°

RST = (2x - 6)° = (2*28 - 6)° = 50°

The measure of the left angle is 85 degrees, and the measure of the right angle is 50 degrees.

The required result of the sliding filament model given below.

The mechanism by which muscles contract is described by the sliding filament model. Actin and myosin myofilaments move over one another as a result of a cycle of repeated occurrences, constricting the sarcomere and creating tension in the muscle.

The A band is the middle, darkly pigmented area of the sarcomere that runs the entire length of the thick filaments. The portion of the thin filaments that cross over the thick filaments is also included. The I band is formed by the remaining thin filaments within the sarcomere but not by any thick filaments. Each A band has a narrow region in the middle called the H zone, which is made up entirely of dense filaments.

Myosin heads pull the thin filaments in the direction of the M line during muscle contraction. Because of this, the thin filaments glide inward, allowing their ends to overlap and connect at the sarcomere's core. The I band and H zone become smaller as a result.

Answer:0.757

Step-by-step explanation:

The ages of Wilson, Randy and Greg given their total ages is 7, 10 and 15 years respectively.

This means that the total ages of Wilson, Randy and Greg is 7 years, 10 years and 15 years.

Let's represent the information above as follows:

The total ages = Wilson + Randy + Greg

That is, Wilson's age, Randy's age and Greg's ages is given as:

32 = x + (x + 3) + (x + 3) + 5

32 = x + x + 3 + x + 3 + 5

32 = 3x + 11

32 - 11 = 3x

21 = 3x

x = 21/3

x = 7 years

Therefore, from the calculations above,

Wilson's age = x

= 7 years

Randy's age = (x + 3)

= 7 + 3

= 10 years

Greg = (x + 3) + 5

= (10) + 5

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

[tex]3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}[/tex]

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

[tex]\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}[/tex]

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

length = 17 units

We are given to find the dimensions of a rectangle with an area equal to the parallelogram with vertices (6, 21), (14, 15), (6, 0), and (-2, 6).

If we have two points with coordinates as (a, b) and (c, d) The distance is given by the formula: √[(c - a )² + (d - b)²]

Now, of the coordinates are labelled as;

A(6, 21), B(14, 15), C(-2,6),  (6,0)

Thus;

AB = √(14 - 6)² + (15 - 21)² = √100 = 10 = CD
