Answers

Should be 160 chairs

To determine the total number of chairs in the restaurant, multiply the count of tables with 2 chairs (20 tables) by 2, and those with 4 chairs (30 tables) by 4, and sum the two products to get a total of 160 chairs.

To calculate the total number of chairs in the restaurant, we first need to find out how many tables are there with 2 chairs and how many with 4 chairs. Since 40% of the tables have 2 chairs, we multiply 40% (or 0.4) by the total number of tables (50) to find the number of tables with 2 chairs, which equals to 20 tables.

The remaining 60% of the tables have 4 chairs, so we multiply 60% (or 0.6) by the total number of tables (50) to find the number of tables with 4 chairs, which equals to 30 tables.

To find the total number of chairs, we multiply the number of tables with 2 chairs (20) by 2 and the number of tables with 4 chairs (30) by 4, then we add the two results together:

Tables with 2 chairs: 20 tables imes 2 chairs/table = 40 chairs

Tables with 4 chairs: 30 tables imes 4 chairs/table = 120 chairs

So, the total number of chairs in the restaurant is:

40 chairs + 120 chairs = 160 chairs

Without actual division show that f(x) = (x3 − 3x2 − 13x + 15) is exactly divisible by g(x) = (x2 + 2x − 3).

Answers

Answer:

see explanation

Step-by-step explanation:

Note that the sum of the coefficients of g(x)

1 + 2 - 3 = 0

Hence x = 1 is a root of g(x) and (x - 1) is a factor

Note the sum of the coefficients of f(x)

1 - 3 - 13 + 15 = 0

hence x = 1 is a root of f(x) and (x - 1) is a factor

Since (x - 1) is a factor of both

Then f(x) is also divisible by x² + 2x - 3

2+3x16-2x21-3=?

Please help me solve this equation.

Answers

Answer:5

Step-by-step explanation:

To solve the expression 2 + 3x16 - 2x21 - 3, we apply the order of operations rule (PEMDAS) without any parentheses or exponents to handle. The expression simplifies to 5.

The student is asking to solve a mathematical expression using the correct order of operations. The proper order to solve math expressions is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This rule is often remembered by the acronym PEMDAS.

Let's solve the expression step by step:

First calculate any operations inside parentheses. In the given problem, there are none.

Next, perform all multiplication and division operations from left to right. 3x16 equals 48, and 2x21 equals 42.

Subtract and add from left to right. So, 2 + 48 - 42 - 3 = 5.

Therefore, the expression

2 + 3x16 - 2x21 - 3= 5

cone-shaped paperweight has a diameter of 3 inches and a height of 5 inches.

What is the volume of the paperweight?

Use 3.14 for pi.

Enter your answer, as a decimal, in the box.

Answers

Answer: [tex]V=11.775\ in^3[/tex]

Step-by-step explanation:

You need to use the formula for calculate the volume of a cone. This is:

[tex]V=\frac{1}{3}\pi r^2h[/tex]

Where "r" is the radius and "h" is the height.

You know that the diameter of the cone-shaped paperweight is 3 inches. Then, you need to divide the diameter by 2 to find the radius:

[tex]r=\frac{3in}{2}\\\\r=1.5\ in[/tex]

Now you know that:

[tex]r=1.5\ in\\h=5\ in\\\pi=3.14[/tex]

Substituting these values into the formula [tex]V=\frac{1}{3}\pi r^2h[/tex], you get that the volume of the  paperweight is:

[tex]V=\frac{1}{3}(3.14)(1.5\ in)^2(5\ in)[/tex]

[tex]V=11.775\ in^3[/tex]

The volume of the paperweight will be 11.76 cubic inches.

What is the volume of a cone?

Let d be the diameter of the base circle and h be the height of the cone.

Then the volume of the cone will be

V = 1/12 x πd² x h

The cone-shaped paperweight has a diameter of 3 inches and a height of 5 inches.

Then the volume of the paperweight will be

V = 1/12 x π(3)² x 5

V = 1/12 x 3.14 x 9 x 5

V = 11.76 cubic inches

Find all polar coordinates of point P where P = ordered pair 3 comma negative pi divided by 3 .

Answers

Final answer:

The student's question relates to the point P with the polar coordinates (3, -π/3). Polar coordinates are not unique, so we can find all coordinates of point P by adding multiples of 2π to the angle part of the coordinate, that is, (3, -π/3 + 2πn) where n is an integer.

Explanation:

The polar coordinates system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from the origin (point O) and an angle measured anti-clockwise from an arbitrary direction, usually the x-axis.

Each point is represented by the ordered pair (r, θ). Our point P has the polar coordinates (3, -π/3). However, polar coordinates are not unique for a given point. To find all polar coordinate pairs for point P, we add multiples of 2π to the angle part of the coordinate pair, as a complete revolution is 2π in radians. Therefore, alternative polar coordinate pairs for point P would include (3, -π/3 + 2πn) where n is an integer.

Examples include:

(3, -π/3) when n=0 (3, 2π -π/3) when n=1, giving (3, 5π/3) (3, 4π -π/3) when n=2, giving (3, 11π/3) And so on, for all integers n.

The legs of a right triangle are 3 units and 6 units. What is the length of the hypotenuse?

Answers

Answer:

The length of the hypotenuse is [tex]h = 6.71\ units[/tex]

Step-by-step explanation:

For a straight triangle it is true that

[tex]h = \sqrt{a ^ 2 + b ^ 2}[/tex]

Where has is the hypotenuse of the right triangle and a and b are the lengths of the other two sides.

In this case we know that:[tex]a = 3\\b = 6[/tex]

So the hypotenuse is:

[tex]h = \sqrt{3 ^ 2 + 6 ^ 2}[/tex]

[tex]h = \sqrt{3 ^ 2 + 6 ^ 2}[/tex]

[tex]h = 3*\sqrt{5}[/tex]

[tex]h = 3*\sqrt{5}[/tex]

[tex]h = 6.71[/tex]

ANSWER

The hypotenuse is 3√5 units.

EXPLANATION

We use the Pythagoras Theorem.

Let h be the hypotenuse.

The Pythagoras Theorem says that, the hypotenuse square is equal to the sum of the squares of the two shorter legs.

[tex] {h}^{2} = {3}^{2} + {6}^{2} [/tex]

[tex]{h}^{2} = 9+ 36[/tex]

[tex]{h}^{2} = 45[/tex]

Take positive square root.

[tex]h = \sqrt{45} [/tex]

Answers

Definition of average rate of change a function g(x) over an interval [a,b]:

[tex]A = \dfrac{g(b)-g(a)}{b-a}[/tex]

Substitute your function and your interval:

[tex]A = \dfrac{(3^6-6)-(3^0-6)}{3-0} = \dfrac{3^6-6-3^0+6}{3} = \dfrac{3^6-1}{3} = \dfrac{728}{3}[/tex]

Final answer:

The average rate of change of the function gx) = 3(2x) - 6 over the interval [0,3] is calculated as (g(3) - g(0)) / (3 - 0) which equals to 6.

Explanation:

The average rate of change of a function over an interval [a,b] is defined as:

(g(b) - g(a)) / (b - a)

Here, the function g(x) = 3(2x) - 6, and the interval is [0,3]. Let's calculate g(3) and g(0).

g(3) = 3(2*3) - 6 = 12

g(0) = 3(2*0) - 6 = -6

Now, apply these values to the average rate of change formula:

(g(3) - g(0)) / (3 - 0) = (12 - (-6)) / 3 = 18 / 3 = 6.

So, the average rate of change of the function g(x) over the interval [0,3] is 6.

S = 196

a₁ = 2(1) - 1 = 1

an = 2n - 1

The volume of a prism which has an altitude of 10 units and has a right triangle base with a hypotenuse of 13 units and a leg of 12 units is:

Answers

Answer:

The volume of the prism = 300 units³

Step-by-step explanation:

* Lets study the triangular prism

- The triangular prism has 6 faces

- Two right triangular bases

- Four rectangular side faces

- The volume of the prism = area of its base × its height (altitude)

* Now lets solve the problem

∵ The base is a right triangle with a hypotenuse of 13 units and

   a leg of 12 units

∵ The area of the right triangle = 1/2 × leg1 × leg2

- You can find the length of other leg by using Pythagoras theorem

∵ (hypotenuse)² = (leg1)² + (leg2)²

∵ hypotenuse = 13 units

∵ leg1 = 12 units

∴ (13)² = (12)² + (leg2)²

∴ 169 = 144 +  (leg2)² ⇒ subtract 144 from both sides

∴ 25 =  (leg2)² ⇒ take √ for both sides

∴ leg2 = 5 units

- The area of the right triangle = 1/2 × leg1 × leg2

∴ The area of the base = 1/2 × 12 × 5 = 30 units²

∴ The volume of the prism = 30 × 10 = 300 units³

A city’s population is about 763,000 and is increasing at an annual rate of 1.5%. Predict the population of the city in 50 years.

Answers

Answer:

Population will be approx 1606300.

Step-by-step explanation:

Given that a city’s population is about 763,000 and is increasing at an annual rate of 1.5%. Now we need to predict the population of the city in 50 years.

We can use growth formula

[tex]A=P\left(1+r\right)^t[/tex]

Where P=763000

rate r=1.5% = 0.015

time t = 50 years

Plug these values into above formula

[tex]A=763000\left(1+0.015\right)^{50}[/tex]

[tex]A=763000\left(1.015\right)^{50}[/tex]

[tex]A=763000\left(2.10524242061\right)[/tex]

[tex]A=1606299.96692[/tex]

Hence population will be approx 1606300.

Therefore, the predicted population of the city in 50 years is approximately [tex]$1,586,997$[/tex].

To predict the population of the city in 50 years, we can use the formula for compound interest, where the principal is the initial population, the interest rate is the annual growth rate, and the time is 50 years.

Given:

- Initial population = 763,000

- Annual growth rate = 1.5% = 0.015

Step 1: Calculate the total growth factor after 50 years using the compound interest formula.

Growth factor = [tex](1 + r)^_t[/tex]

Growth factor =[tex](1 + 0.015)^_{50}[/tex]

Growth factor = [tex]$1.015^{50} = 2.079$[/tex]

Step 2: Calculate the final population by multiplying the initial population with the growth factor.

Final population = Initial population × Growth factor

Final population = 763,000 × 2.079

Final population = [tex]$1,586,997$[/tex]

1. value of A

x=A, y = 9 and k = 4.5 (given)

y = k/x

9 = 4.5/A

=> A = 4.5/9

=> A=0.5

2. Value of B

x =1, y= B, k = 4.5

y = k/x

B = 4.5/1

B= 4.5

3. Value of C

x=C, y=3. k=4.5

y = k/x

3 = 4.5/C

3C = 4.5

C = 4.5/3

C = 1.5

4. Value of D

x= 9, y=D, k=4.5

y = k/x

D = 4.5/9

D = 0.5

Answer:

[tex]A=0.5[/tex]

[tex]B=4.5[/tex]

[tex]C=1.5[/tex]

[tex]D=0.5[/tex]

Step-by-step explanation:

The form an the equation of inverse variation is:

[tex]y=\frac{k}{x}[/tex]

Being "k" the constant of variation.

Since we know "k" and we have the values given in the table, we can find the missing values:

To find A we need to substitute the [tex]y=9[/tex], the value of "k" and [tex]x=A[/tex] into the equation and solve for "A":

[tex]9=\frac{4.5}{A}[/tex]

[tex]A=\frac{4.5}{9}=0.5[/tex]

To find B we need to substitute the [tex]x=1[/tex], the value of "k" and [tex]y=B[/tex] into the equation:

[tex]B=\frac{4.5}{1}=4.5[/tex]

To find C we need to substitute the [tex]y=3[/tex], the value of "k" and [tex]x=C[/tex] into the equation and solve for "C":

[tex]3=\frac{4.5}{C}[/tex]

[tex]C=\frac{4.5}{3}=1.5[/tex]

To find D we need to substitute the [tex]x=9[/tex], the value of "k" and [tex]y=D[/tex] into the equation:

[tex]D=\frac{4.5}{9}=0.5[/tex]


Jasmine wants to lose weight for an upcoming wedding. She currently weighs 186 pounds and her goal is to weigh 140 pounds. After consulting with her doctor, she feels she can safely lose 2 pounds per week. The graph tracks the projected weight loss over time.



Write an equation for the weight loss trend. Use W = weight (lb) and t = time (weeks).


how long will it take Jasmine to achieve her desired weight goal.
weeks

What is the slope

Answers

186-140=46/2=23 weeks -2/23=slope

Answer:

Equation is W = -2t+186

It will take 23 weeks to achieve the goal.

Slope = -2 pounds per week

Step-by-step explanation:

Here  current Weight  is 186 pounds

and her goal is to weigh 140 pounds

she can safely lose 2 pounds per week which is the slope

for t =0 , W =186 pounds  (Y intercept )

    slope = 2 pounds per week

since its decreasing therefore its negative

W = -2t+186 is the equation

To achieve the desired goal W = 140

plugging W = 140 and solving for t

140 = -2t+186

2t = 186-140

2t = 46

t = 23

It will take 23 weeks to achieve the goal.

Slope = -2 pounds per week
