A Trellis Consists Of Overlapping Wooden Slats.1.What Is The Position Of The Indicated Angles?2.What

Answers

Answer 1

The position of the angles are corresponding angles.

The value of x should be 6 for the slats to be parallel.

The theorem use to prove the parallel slat is the corresponding angle theorem.

The measure of the indicated angles are 42 degrees.

How to know a corresponding angles?

Corresponding angles are the angles that are formed when two parallel lines are intersected by the transversal.

Therefore, the position  of the angles are corresponding angles

Since the angles are corresponding angles, they are congruent.

Therefore,

3x + 24 = 7x

24 = 7x - 3x

24 = 4x

x = 6

The theorem use to prove the postulate is the corresponding  angle theorem.

The measure of the indicated angle can be calculated as follows:

7(6) = 42 degrees.

Answer:

y-2x-2

Step-by-step explanation:

The way I would do this is by first using the information given and making an equation in point-slope form, before bringing it to y=mx+b.

We know that the slope is -2, and we have a point, (2,-6). The formula for equations in point slope form is [tex]y-y_{1} =m(x-x_{1} )[/tex]. So, we can insert the given information into this formula to get [tex]y+6=-2(x-2)[/tex].

Next, we distribute the slope to the the parenthesis to get [tex]y+6=-2x+4[/tex]

Then, we subtract 6 from both sides to get [tex]y=-2x-2[/tex]

Since this equation is now in the form [tex]y=mx+b[/tex], the answer is [tex]y-2x-2[/tex]

Eleni is helping to organize a school trip. She needs to find the best deal out of the three bus companies. 260 students are going on the trip. First Student charges $350 per bus. They will need 7 buses. Stock Transportation charges $500 to cover the cost for the drivers plus $6 per student. Switzer-Carty charges $7 per student. Write an algebraic equation for each company and solve it to find out which is the least expensive.

Answers

The least expensive is the Stock Transportation charges $500 to cover the cost for the drivers plus $6 per student.

How to form mathematical expression from the given description?

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically.

For example, if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4.

If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Let the number of students the bus carries be x.

First Student charges $350 per bus. They will need 7 buses.

Therefore, the cost of the school hiring the bus is:

C = 7*350

C = 2450

The charge of per student

= 2450 / 260

= $ 9.4

Stock Transportation charges $500 to cover the cost for the drivers plus $6 per student.

C = 500 + 6*260

C = 500 + 1560

C = 2060

Switzer-Carty costs $7 for every student that they bus.

Therefore, the cost of the school hiring the bus is:

C = 7 * x

C = 7x

To bus 260 students, then, the cost will be:

C = 7 * 260

C = $1820

The cost of a tea cup and a cup of coffee in the shop is £0.90 and £1.50 respectively.

How to write and solve equation?

let

x = cost of teay = cost of coffee

x + 2y = 3.90

Inequalities help us to compare two unequal expressions. (-6, 3) is not the solution to the system of inequalities.

What are inequalities?

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The graph of y ≥ −3x + 3 will be a solid line with the equation y=−3x + 3, this solid line signifies that the value on this line is also included in the solution. Since the symbol is '≥' therefore the area above the line will have the solutions.

The graph of y<(3/2)x -6 will be a dashed line with the equation y=(3/2)x - 6, this dashed line signifies that there is no solution on the line. since the inequality symbol is '<' therefore, the area under the dashed line will have all the solutions.

The area where both shaded areas meet is the area that will have all the possible solutions.

PartB:

How to solve for x and what does x equal in this?​

Step-by-step explanation:

so these two angles add up to 180 degrees

7x -3 + 12x -7 = 180

7x+12x=180+7+3

19x=190

x=10

to check if this is true we can input 10 for x in each side.

7(10)-3 = 67

12(10)-7 = 113

113+67 = 180

The answer is A, or 10.

Explanation:

These two angles are supplementary, meaning that they add up to 180 degrees. Upon plugging 10 in as x, you would get 67 as the answer for the left angle measurement and 113 as the answer for the right angle measurement. Because 67 + 113 = 180, you know that the math you did is correct. Linear pair angles always are supplementary, and they are directly beside each other horizontally or vertically.

Step 1: Choose a point on the line, such as (2, 5).
Step 2: Choose another point on the line, such as (1, 3).
Step 3: Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is StartFraction one-half EndFraction.

The slope of a line or straight object is the ratio of how much amount of rise occurs in correspondence to the increment in the run.

Slope = rise/ run

Calculating the slope using two points on the line, (2, 5) and (1, 3), we have:

Slope (m) = (5 - 3)/(2 - 1)

Slope (m) = (2)/(1)

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

Density = mass/volume

A brick of aluminum weighs 19,745 grams and has the following dimensions: length 29 cm, height 15 cm, and width 51 mm.
