Answers

Answer:

I don't know answer what

The partial pressure of c₂h₂ is25 atm.

What is partial pressure?

When more than one gas is present in a container, each gas exerts pressure, which is known as partial pressure. Its partial pressure refers to the pressure of any gas inside the container.

Partial pressures can be calculated in one of two ways:

To determine the individual pressure of each gas in a mixture, use PV = nRT. Determine the proportion of pressure from the total pressure that may be assigned to each individual gas by using the mole fraction of each gas.

When there is a combination of two or more gases in a given volume, the pressure created by each individual gas in the mixture is expressed using the phrase partial pressure.

The partial pressures of the individual gases make up the total pressure of the gas combination. P1 + P2 + P3 = Ptot = Pi

Explanation:

i took the test rn

From the data that we have here the total number of people that are known to work for 4 hours per shift is 2.

How to solve for the workers

The sum of all of these probabilities would be equal to 1. Hence we would have:

0.1+x+0.14+0.36+0.3+0,06 = 1

x + 0.96 = 1

x = 1 - 0.96

x = 0.04

The total number of people that is said to work for this manager is said to be 50.

50 x 0.04

= 2

Therefore the total number that work at 4 hours per shift is 2.

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (5 - 2)/(1 - 0)

Slope (m) = 3/1

How many square feet of glass are needed to cover the skywalk floor? (round your final answer to 1 decimal place and any intermediate calculations to 2 decimal places. Be sure to include units. ).

Answers

The area of the skywalk floor is the amount of space it occupies

The area of the skywalk floor is 1728.1 square feet

From the complete question, we have the following parameters

The outer diameter is 65 feet

This is represented as: [tex]\mathbf{d_2 = 65}[/tex]

The inner diameter is calculated as follows:

[tex]\mathbf{d_1 = 65 - 2 * 10}[/tex]

[tex]\mathbf{d_1 = 45}[/tex]

So, the area of the skywalk floor is the difference between the areas of the two semicircles.

This is represented as:

[tex]\mathbf{Area = \frac{\pi d_2^2}{4} - \frac{\pi d_1^2}{4}}[/tex]

Rewrite as:

[tex]\mathbf{Area = \frac{\pi}{4}(d_2^2 - d_1^2)}[/tex]

So, we have:

[tex]\mathbf{Area = \frac{3.142}{4}(65^2 - 45^2)}[/tex]

[tex]\mathbf{Area = \frac{3.142}{4}(2200)}[/tex]

Simplify

[tex]\mathbf{Area = 3.142 \times 550}[/tex]

[tex]\mathbf{Area = 1728.1}[/tex]

Hence, the area of the skywalk floor is 1728.1 square feet

What is a system of inequalities?

The system of inequalities is given with the use of the more than inequalities for the correspondence to one variable.

In the given system, the inequalities lies with the grayscale copies, and color copies with the time limit of 25 minutes and minimum number of 8 copies.

Let the number of color copies = x

The time taken to print each color copy = 4 minutes

Thus, the time taken to print x color copies = 4x

Let the number of gray scale copies = y

The time taken to print each gray scale copy = 2 minutes

Thus, the time taken to print y gray scale copy = 2y

Total copies printed = x + y

Maximum time taken to print x color copies and y grayscale copies = 25 minutes

A small fair charges an admission fee for children and adults. The cost for admission is $3 per adult and $2 per child. On a certain day, total admission fees were $900, and 350 people attended the fair. How many children attended the fair that day? 80 children 150 children 200 children 320 children.

Answers

150 children attended the fair for that day if $900, and 350 people attended the fair, hence option b is correct.

What is the number of children attended the fair?

Detailed explanation:

Let's say there are x youngsters and y grownups.

350 persons in all visited the fair, thus.

So, x + y = 350.

In addition, fees per kid are $2 and fees per adult are $3.

Since, $900 is assumed to represent the entire sales.

So, 2x + 3y = 900

Consequently, we have the equation system,

2x + 3y = 900

x + y = 350

Now let's resolve the equations.

x + y = 350 ⇒ y = 350 - x

The result is that 2x + 3y = 900 2x + 3(350 -x) = 900 2x + 1050 - 3x = 900 -x = -150 x = 150.

The result is that y = 350 - x y = 350 - 150 y = 200.

Therefore, As a result, 150 children and 200 adults, respectively, visited the fair.

I = Prt

P = I / (rt)

where

I is the amount of money in interest

P is the Principal amount of money to be invested

r is the rate of interest  in decimal

t is Number of Time Periods

in this problem we have

t = 9 years  

I = $5,896

P = ?

r = 0.0692
