First we can calculate how many seconds there are in an hour:​

Since 1 hour has 60 minutes and each minute has 60 seconds.​

Then 1 hour = 60 minutes * 60 seconds/1minute = 3,600 seconds.​

Now we have to multiply x 40 to calculate how many seconds there are in 40 hours.​

In a 40-hour work week = 40 hours * 3,600 seconds/1hour = 144,000 seconds​

Answer : 144,000 seconds there are in a 40-hour work week​

The correct formula to calculate the number of seconds in a 40-hour work week is 40 hours * 60 minutes/hour * 60 seconds/minute (option a). This method accurately converts hours to minutes and then minutes to seconds.

The correct formula for calculating the number of seconds in a 40-hour work week is as follows:

a. 40 hours * 60 minutes/hour * 60 seconds/minute

Here's the breakdown:

1. Start with the number of hours, which is 40 hours.

2. Convert hours to minutes using the conversion factor of 60 minutes per hour.

3. Convert minutes to seconds using the conversion factor of 60 seconds per minute.

By multiplying these three factors together, you obtain the total number of seconds in a 40-hour work week.

The other options (b, c, d) do not correctly set up the conversion factors and units, leading to incorrect results.

So, the correct answer is (a), as it correctly converts 40 hours into seconds using the appropriate conversion factors.

The furniture company decreases its chair production by 66%, resulting in a reduction of 5214 chairs. The new production level is 2686 chairs per month.

A furniture company reduces its chair production by 66%. To find the amount of the decrease and the new number of chairs produced, we first calculate the decrease: 7900 chairs × 0.66 = 5214 chairs. Therefore, the reduction in the number of chairs produced is 5214. To find the new production amount, subtract the decrease from the original production: 7900 - 5214 = 2686 chairs.

The new number of chairs produced each month is then 2686 chairs. This calculation helps both the company and stakeholders understand the adjustment in production capacity and potentially adjust business strategies or resource allocation accordingly.

Since the greatest common factor for 48 and 80 is 16 then we conclude the largest number of stack is 16

The largest number of coins that the child can place in each stack is 16, which is the greatest common divisor of the number of quarters (48) and dimes (80) they have.

In this problem, we're looking for the greatest number of coins that can evenly divide both the total number of quarters and the total number of dimes the child has. This can be solved by finding the greatest common divisor (GCD) of the numbers, 48 and 80.

The GCD of 48 and 80 is 16. Therefore, the child can create stacks of 16 coins each (either quarters or dimes), ensuring that each stack has the same number of coins and that all coins are used.

Step-by-step explanation:

Given that in a parallel circuit [tex]E_{T}=277V[/tex], R=56kΩ and [tex]X_{L} =[/tex]68kΩ.

And we are asked to find phase angle.

In any circuit, phase angle[tex]\theta=tan^{-1}(\frac{X_L-X_C} {R})[/tex]

Since we don't have any capacitor,[tex]X_{C}=0[/tex]

Answer:

It IS balanced.  There are 4 Hydrogen atoms on the left and the right and 2 Oxygen atoms on the left and the right.  

Step-by-step explanation:

The given reaction follows the law of conservation of mass and is balanced. Thus, the correct option is C.

The balanced chemical equation for the reaction has been:

[tex]\rm 2\;H_2\;+\;O_2\;\rightarrow\;2\;H_2O[/tex]

The law of conservation of mass states that the mass of each element on the product and the reactant side has been equal. The mass has been proportional to the number of atoms, thus the atoms have been equal on both sides of the reaction.

In the given reaction:

Reactant = 4

Product = 4

Reactant = 2

Product = 2

Since there has been the same number of atoms of each element on both sides of the reaction, the reaction has been termed a balanced reaction. The law of conservation of mass has been followed in the equation.

Thus, option C is correct.

Given

He earns a commission of 5 percent on the first 10 suits.

he sells more than 10, he earns an additional 3 percent on the additional suits

Last weekend Juan sold 13 suits at a price of $250 each.

Find out Juan Ramirez commission

To proof

As given in the question

Juan sold 13 suits at a price of $250 each

13 suit selling price = 13 × 250

                               = $ 3250

As given

He earns a commission of 5 percent on the first 10 suits.

and for more than 10, he earns an additional 3 percent on the additional suits

Juan Ramirez sells 13 suit which are more than the 10 suits

Hence  

commission percent for the 13 suits = 8 %

First write 8% in the decimal form

[tex]= \frac{8}{100}[/tex]

=0.08

Than commission on the 13 suits = 0.08 × 3250  

                                                       = $260.

Therefore option ( D) is correct.

Hence proved

The y-intercept of the equation 6x + 12y = 60 is 5, and the slope of the line through points (1, -1) and (-2, 8) is -3. Therefore the correct option is A.

Finding the Y-Intercept of a Linear Equation

To find the y-intercept of the linear equation 6x + 12y = 60, we need to set x to 0. If x=0, the equation simplifies to 12y = 60. Dividing both sides by 12 gives us the y-intercept: y = 5. Therefore, the correct answer is A: 5.

Calculating the Slope between Two Points

The slope of a line containing the points (1, -1) and (-2, 8) can be found by using the formula (y2 - y1) / (x2 - x1). Substituting the given points into the formula results in: (8 - (-1)) / (-2 - 1) = 9 / -3 = -3.

x + 3y + z = 1   -------> first equation

2x – y – z = 6  -------> second equation

5x + y + z = 1 -------> third equation

Add second and third equation

2x – y – z = 6  -------> second equation

5x + y + z = 1 -------> third equation

-------------------------------------------------

7x = 7 (divide by 7 on both sides)

So x= 1

Now we add first and second equations

x + 3y + z = 1   -------> first equation

2x – y – z = 6  -------> second equation

-------------------------------------

3x +2y = 7

We already got x=1, replace it in the above equation

3(1) + 2y = 7

3 + 2y = 7 (subtract 3)

2y = 4 (divide both sides by 2)

So y =2

Now plug in the values in first equation

x + 3y + z = 1   -------> first equation

1 + 3(2) + z = 1

7 + z = 1 (subtract 7 from both sides)

z = -6

Answer is (1, 2, -6)

2y - 3 > -1    |add 3 to both sides

2y > 2     |divide both sides by 2

y > 1

5 - y > 4      |subtract 5 from both sides

-y > -1      |change the signs

y < 1

y > 1 or y < 1

The equivalent of 10095 m/s is 6.2728 mi/s.

Further Explanation

To get the answer to this problem we use the conversion factor for meters to miles: 1609.34 m = 1 mi.

Setting up the dimensional analysis:

[tex]speed \ = 10095 \frac{m}{s} \times \frac{1 \ mi}{1609.34 \ m}\\[/tex]

We put the number of meters in the numerator so that the unit (meter) may be cancelled.

By multiplying the given by the number of meters in mile, we arrive at the answer:

[tex]\boxed {\boxed {speed = 6.2728 \ \frac{mi}{s}}}[/tex]

Since the given has 5 significant figures, the final answer must also have five significant figures.

Additional Example:

Sometimes the problem requires the conversion of both numerator and denominator. Below is a worked example for these kinds of question.

The conversion factor relating miles to meters is 1mile=1610m. The speed of light is 3.00×108 m/s. How fast is this in miles per hour (miles/h)?

The problem gives the conversion factor for miles to meter:

1 mi =1610 m

To convert the speed of light into the desired unit the following steps must be carried out:

These conversion may be done individually or simultaneously in a single dimensional analysis equation. The equation below shows the simultaneous conversion in one equation:

[tex]speed \ of \ light = 3.00 \times 10^8 \ \frac{m}{s} \times \frac{1 \ mi}{1610 \ m} \times \frac{60 \ s}{1 \ min} \times \frac{60 \ min}{1 \ h}\\\\\boxed {speed \ of \ light = 6.71 \times 10^8 \ \frac{mi}{h}}[/tex]
