What are the labor supply and demand curves

Answers

The intersection of the labor supply and demand curves determines the equilibrium wage rate and quantity of labor.

The labor supply and demand curves are used to analyze the market of labor, where the demand is the amount of labor that employers are willing to hire at a given wage, and the supply is the amount of labor that individuals are willing to supply at a given wage. The labor supply curve is upward sloping and shows the quantity of labor supplied at different wages. Mathematically, this is represented as the equation: Qs = a + bw, where Qs is the quantity of labor supplied, a is a constant, b is the elasticity of labor supply, and w is the wage. The labor demand curve is downward sloping and shows the quantity of labor demanded at different wages. Mathematically, this is represented as the equation: Qd = c – dw, where Qd is the quantity of labor demanded, c is a constant, d is the elasticity of labor demand, and w is the wage. The intersection of the labor supply and demand curves determines the equilibrium wage rate and quantity of labor.

12 Colin used 2 5/6 sheets of paper and completed 1/6 of his report. How many pages was the completed report?

Answers

Answer:

below

Step-by-step explanation:

He needs 6 times as many as 1/6 th  to have a complete report

  6 * 2 5/6 =   6  * 17/6 = 102/6 = 17 pages total

If Colin used 2 5/6 sheets of paper to complete 1/6 of his report, we can use this information to find out how many sheets he will need to complete the entire report.

Let's start by finding out how many sheets of paper Colin used for each 1/6 of the report. We can divide the total number of sheets he used (2 5/6) by the fraction of the report he completed (1/6):

(2 5/6) ÷ (1/6) = (17/6) ÷ (1/6) = 17

So Colin used 17 sheets of paper to complete 1/6 of the report.

To find out how many pages the completed report will be, we need to multiply the number of sheets used to complete 1/6 of the report by the total number of 1/6ths in the completed report. Since 1/6 represents the fraction of the report that Colin has completed, there are 5/6 of the report left to complete:

1/6 + 5/6 = 6/6 = 1 (the completed report)

So there are a total of 6 1/6ths in the completed report. To find the total number of sheets, we can multiply the number of sheets used to complete 1/6 of the report by 6:

17 sheets x 6 = 102

Therefore, Colin will need a total of 102 sheets of paper to complete the entire report.

An elevator travels directly up 36 floors in 108 seconds. How many floors can this elevator travel directly up in 80 seconds?

Answers

The number of floors can this elevator travel directly up in 80 seconds is, 26 2/3 floors

What is the relation between time, distance & speed ?

The distance covered by the object is equal to the product of the speed at which the object is moving and time taken for covering the distance.

Distance = Time × Speed

We are given that the elevator travels 36 floors in 108 seconds, so the rate can be calculated as follows:

rate = 36 floors / 108 seconds

      = 1 floor / 3 seconds

To determine how many floors the elevator can travel in 80 seconds, we can use the rate and the formula: distance = rate x time:

distance = rate x time

distance = (1 floor / 3 seconds) x 80 seconds

distance = 80 / 3 floors

distance = 26 2/3 floors

So, the elevator can travel directly up 26 2/3 floors in 80 seconds.

Answer is B and second one is 19.9

Answers

Answer:

Second option:

[tex]\mbox{\large \dfrac{a}{\sin(35^\circ)} = \dfrac{30}{\sin(60^\circ)}}[/tex]

Step-by-step explanation:

The law of sines states that the ratio of the sides of a triangle to the sine of the angle opposite the sides is the same for both sides

So we get

[tex]\dfrac{AB}{\sin 85} = \dfrac{BC}{\sin 35} = \dfrac{AC}{\sin B}}[/tex]

We are not given ∠B but we know the three angles of a triangle must add up to 180°

Therefore m∠B + 35 + 85 = 180

m∠B  + 120 = 180

m∠B = 180 - 120 = 60°

and we also have AB = c. BC = a and AC = 30

Hence

[tex]\dfrac{c}{\sin 85} = \dfrac{a}{\sin 35} = \dfrac{30}{\sin 60}}\\\\\textrm{from which}\\\\ \dfrac{a}{\sin 35} = \dfrac{30}{\sin 60}}\\[/tex]

The equation which will yield the value of a will be : a/sin35 = 30/sin60

Given,

Triangle.

Here,

According to sine law,

30/sinB = c / sin85 = a/ sin35

Firstly calculate angle B .

Therefore m∠B + 35 + 85 = 180

m∠B  + 120 = 180

m∠B = 180 - 120 = 60°

Here,

AB = c.

BC = a

AC = 30

Hence to calculate a ,

Use the proportion,

a/sin35 = 30/sin60

We are given that;

a) x²+3x-4

b) x²-2x-3

c) x²+2x-8

Now,

a) To factorise x²+3x-4, we need to find two numbers whose product is -4 and whose sum is 3. Those numbers are 4 and -1, so we can write:

x²+3x-4 = (x+4)(x-1)

b) To factorise x²-2x-3, we need to find two numbers whose product is -3 and whose sum is -2. Those numbers are -3 and 1, so we can write:

x²-2x-3 = (x-3)(x+1)

c) To factorise x²+2x-8, we need to find two numbers whose product is -8 and whose sum is 2. Those numbers are 4 and -2, so we can write:

A rhombus has sides of length 8 m. It’s shorter diagonal is 10 m long. Find the length of the longer diagonal

Answers

Answer:

Step-by-step explanation:

Here's how you can find the length of the longer diagonal of a rhombus with sides of length 8 m and a shorter diagonal of length 10 m:

Step 1: Draw a diagram of the rhombus with the shorter diagonal labeled as 10 m.

Step 2: Draw a perpendicular bisector from one corner of the rhombus to the opposite corner, dividing the rhombus into two congruent right triangles.

Step 3: Label the longer diagonal as "d".

Step 4: Since the two congruent right triangles have sides that are half the length of the sides of the rhombus, the hypotenuse of each triangle must have length 4 m.

Step 5: Using the Pythagorean theorem, we can find the length of the other side of each triangle:

a^2 + b^2 = c^2

4^2 + b^2 = 10^2

16 + b^2 = 100

b^2 = 84

b = √84 = 2√21

Step 6: Now that we know the length of one side of each triangle, we can use it to find the length of the longer diagonal:

d^2 = 4^2 + (2√21)^2

d^2 = 16 + 168

d^2 = 184

d = √184 = 2√23

So, the length of the longer diagonal of the rhombus is 2√23 m.

What is the difference between absolute and relative error?

Answers

Absolute error and relative error are two measures of the difference between an estimated or calculated value and the true or exact value of a quantity.

The main difference between absolute and relative error is that absolute error gives the magnitude of the difference between the estimated value and the true value, while relative error gives a measure of this difference relative to the size of the true value.

Absolute error is the magnitude of the difference between the estimated or calculated value and the true value.

It is calculated as the absolute value of the difference between the estimated value and the true value. Absolute error is expressed in the same units as the quantity being measured.

Relative error, on the other hand, is the absolute error expressed as a fraction or percentage of the true value. It is calculated as the absolute error divided by the true value, and is usually expressed as a percentage.

Relative error is a useful measure when the scale of the quantity being measured varies over a wide range, or when comparing the accuracy of measurements of different quantities.

a man brought some glasses at 12 each and 5 broke so he sold remaining at 16 each and made profit of rupees 160.find number of glasses he bought

Answers

Answer:

number of glasses he bought = 60

Step-by-step explanation:

Let the variable x represent the number of glasses he bought

Total cost of x glasses at Rs. 12 each = 12x

5 glasses broke so remaining number of glasses = x- 5

He sold this quantity of glasses for Rs. 16 each

Total sale price of (x - 5) glasses = 16(x - 5)

Total profit = Total sales - Total cost = 160

=> 16(x - 5) - 12x = 16

Expand brackets for 16(x - 5): 16x - 16 x 5 = 16x - 80

Therefore we get

16x - 80- 12x = 160

4x - 80 = 160

The net of a right rectangular pyramid is shown.

What is the surface area of the right rectangular pyramid?

Answers

The surface area of the right rectangular pyramid is 96 sq. ft.

What is the net's surface area?

A net pattern is produced when the surface of a three-dimensional figure or solid is spread out flat and each aspect of the shape is visible. The net may then be used to calculate the solid's surface area.

The surface area of the net is calculated by adding the areas of all of its faces. The net's surface area is calculated by summing the surface areas of all its forms.

The surface area of the given net is calculated by adding the area of all the individual shapes in the net.

For the given net the area of the triangle with h= 5 ft and b = 8 ft is:

A1 = 1/2(8)(5)

A1 = 20 sq. ft.

There are two such triangles thus:

A1 = 2(20) = 40 sq. ft

For the triangle with h = 6 ft and b = 4 ft:

A2 = 1/2)(4)(6)

A2 = 12

There are two such triangles thus:

A2 = 2(12) = 24 sq. ft

The area of the rectangle in the center is:

A3 = (8)(4)

A3 = 32 sq. ft

The total surface area of the net is:

A = A1 + A2 + A3

A = 40 + 24 + 32

A = 96 sq. ft.

Answers

System of equations can be used to find each digit is option A.

Describe Equation?

An equation is a mathematical statement that shows that two expressions are equal to each other. It consists of two sides, the left-hand side (LHS) and the right-hand side (RHS), separated by an equal sign (=). The LHS and RHS can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and roots.

Let's represent the hundreds, tens, and units digits as h, t, and u, respectively. Then we can use the given information to set up a system of equations:

A three-digit number has a digit sum of 13:

h + t + u = 13

One more than the hundreds digit (h) is the tens digit (t):

t = h + 1

The digit in the units, u, is 3 greater than the total of the digits in the tens and hundreds:

u = t + h + 3

Therefore, the correct system of equations is:

h + t + u = 13

t = h + 1

u = t + h + 3
