The final answer is

All 3 angles add up to 180 degrees.

so 40 + 2x + 3x = 180

40 + 5x = 180

5x = 140

x = 28

So angle A = 2x = 2(28) = 56 degrees.

Answer: 56°

Step-by-step explanation:

We know that a triangle's angles add up to 180 degrees. We will create an equation to help us solve for x using this information.

     Given:

           2x + 3x + 40 = 180

     Combine like terms:

           5x + 40 = 180

     Subtract 40 from both sides of the equation:

           5x = 140

     Divide both sides of the equation by 5:

           x = 28

Next, we will substitute this value of x into the expression for ∠A.

     ∠A = 2x = 2(28) = 56°

Answer:

y=x

Step-by-step explanation:

bcoz in graph work its normally y=x

6 tables are required. Each prime number attender should serve 3 customers each.

The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

All the numbers other than prime numbers are composite numbers.

The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.

Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.

Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables

Therefore, 6 tables are required.

Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.

Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.

Thus, each prime number attender should serve 3 customers each.

Step-by-step explanation:

The requied solution are (f+g)(x) = 10x² + 10 - 5x and (f-g)(x) = 10x² + 6 + 5x.

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

The functions are given in the question, as follows:

f(x) = 10x² + 8 and g(x) = 2 - 5x

To find (f+g)(x) we add f(x) and g(x) term by term.

(f+g)(x) = f(x) + g(x)

Substitute the values of given functions, and we get

(f+g)(x) = 10x² + 8 + (2 - 5x)

(f+g)(x) = 10x² + 10 - 5x

To find (f-g)(x) we subtract g(x) from f(x) term by term.

(f-g)(x) = f(x) + g(x)

(f-g)(x) = 10x² + 8 - (2 - 5x)

(f-g)(x) = 10x² + 6 + 5x

The solution to the equation given by M * M * M = 729 is 9

An equation is an expression that shows the relationship between two or more numbers and variables using mathematical operations. An equation can be linear, quadratic, cubic and so on, depending on the degree of the variable.

Given the equation:

M.M.M = 729

This gives:

M * M * M = 729

Answer:

y=x/3+2

Step-by-step explanation:

Slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

3y=x+6

We need y so we divide both sides by 3 and we get

y=x/3+2

Answer:

y=1/3 + 2

Step-by-step explanation:

-x+3y=6

add x to both sides (if you add the same amount to both sides, the equation is still equal)

3y=-x+6

divide the whole thing by 3

y=1/3 + 2

so basically your slope is 1/3. That means you rise one, over three.

Plot a point at 2 on the y axis, which is the vertical line on the graph.

Go up one box, and then go right 3 and plot another point.

Keep doing the rise 1 over 3 until you have enough points for a line. 2 points should do, but more points on a graph = a better line.

By the way, slope-intercept form is y=mx+b.

m = slope (steepness of line, 1/3)    b = y-axis intercept (the place that the line touches the y axis)

If you're still stuck with linear equations, take your equation and put it into Desmos graphing calculator, which can be found with a simple search.

Split up each force into horizontal and vertical components.

• 300 N at N30°E :

(300 N) (cos(30°) i + sin(30°) j)

• 400 N at N60°E :

(400 N) (cos(60°) i + sin(60°) j)

• 500 N at N80°E :

(500 N) (cos(80°) i + sin(80°) j)

The resultant force is the sum of these forces,

∑ F = (300 cos(30°) + 400 cos(60°) + 500 cos(80°)) i

… … …  + (300 sin(30°) + 400 sin(60°) + 500 sin(80°)) j N

∑ F ≈ (546.632 i + 988.814 j) N

The opportunity cost of playing football for Graham is $1,190.

The opportunity cost of certain activity in microeconomic theory is the value or gain given up by engaging in that activity in comparison to engaging in an alternative activity. Simply put, if you do a bone activity, you forfeit the potential to choose another.

Given that Graham made $1,100 during football season. Also, Graham spends about $9 on eating out after each game and his team plays a total of 10 games in a season.

Therefore, the opportunity cost of playing football for Graham is,

Opportunity cost

= Amount that Graham would have made in a part-time job +  Total cost of playing football season

= $1,100 + (Number of games × Amount spend in a single game)

= $1,100 + (10×$9)

= $1,100 + $90

= $1,190

Hence, the opportunity cost of playing football for Graham is $1,190.

Adjacent angles refer to those angles that share a common side and common vertex but at the same time, not overlap with each other. In this question , angle <6 is sharing a side and a common vertex  with <5 and <1 without overlapping each other. Therefore, we can say that the angles are adjacent to each other.

Answer:

38 ft, 41 ft, 44 ft, 47 ft

Step-by-step explanation:

let the first piece be x, then

second piece = x + 3

third piece = x + 3 + 3 = x + 6

fourth piece = x + 6 + 3 = x + 9

sum the 4 together and equate to 170

x + x + 3 + x + 6 + x + 9 = 170, that is

4x + 18 = 170 ( subtract 18 from both sides )

4x = 152 ( divide both sides by 4 )

x = 38

Thus

first piece = x = 38 ft

second piece = x + 3 = 38 + 3 = 41 ft

third piece = x + 6 = 38 + 6 = 44 ft

fourth piece = x + 9 = 38 + 9 = 47 ft

The inequality represented by the graph is given as follows:

y > 3x - 4.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

The graph crosses the y-axis at y = -4, hence the intercept b is given as follows:

b = -4.

When x increases by 1, y increases by 3, hence the slope m is given as follows:

m = 3.

Hence the equation of the line is:

y = 3x - 4.

Answer:

The sum of the first nine terms of the sequence is 74.44.

Step-by-step explanation:

Geometric sequence concepts:

The nth term of a geometric sequence is given by the following equation.

\(a_{n+1} = ra_{n}\)

In which r is the common ratio.

This can be expanded for the nth term in the following way:

\(a_{n} = a_{1}r^{n-1}\)

In which \(a_{1}\) is the first term.

Or even:

\(a_{n} = a_{m}r^{n-m}\)

The sum of the first n terms of a geometric sequence is given by:

\(S_{n} = \frac{a_{1}(1 - r^{n})}{1 - r}\)

Finding the common ratio:

\(a_{3} = 3.645, a_{8} = 15\)

\(a_{n} = a_{m}r^{n-m}\)

\(a_{8} = a_{3}r^{8-3}\)

\(a_{3}r^{5} = a_{8}\)

\(3.645r^{5} = 15\)

\(r^{5} = \frac{15}{3.645}\)

\(r = \sqrt[5]{\frac{15}{3.645}}\)

\(r = 1.327\)

Finding the first term:

\(a_{3} = a_{1}r^{2}\)

\(a_{1} = \frac{a_{3}}{r^{2}}\)

\(a_{1} = \frac{3.645}{(1.327)^{2}}\)

\(a_{1} = 2.07\)

Sum of the first nine terms:

\(S_{9} = \frac{2.07*(1 - (1.327)^{9})}{1 - 1.327} = 74.44\)

The sum of the first nine terms of the sequence is 74.44.

Answer:

S₉ = 9.84

Step-by-step explanation:

In a geometric series, the general formula for nth term is:

an = a₁rⁿ⁻¹

where,

an = nth term

a₁ = first term

r = common ratio

From this formula, we have:

a₃ = a₁r² = 3.645   --------- equation (1)

a₈ = a₁r⁷ = 15    ----------- equation (2)

dividing both of these equations, we get:

a₁r⁷/a₁r² = 15/3.645

r⁵ = 4.115

r = (4.115)^1/5

r = 1.33

Now, put this value in equation (1), we get:

a₁(1.33)² = 3.645

a₁ = 0.27

Now, the formula for the sum of geometric series upto nth term is:

Sn = a₁(rⁿ - 1)/(r - 1)

therefore,

S₉ = (0.27)(1.33⁹ - 1)/(1.33 - 1)

S₉ = 9.84
