Kimberly has seven colors of lanyards. she uses three different colors to make a key chain. how many different combinations can she choose?

Answers

Answer 1

The number of different combinations can she choose is; 210.

What is the permutation?

We are told that;

Number of colors of Lanyards she has = 7

Number she wants to use to make a key chain = 3 colours

Thus, number of different combinations can she choose is gotten through permutation formula;

P(n, r) = n!/(n - r)!

P(7, 3) = 7!/(7 - 3)!

P(7, 3) = 210

Thus, the number of different combinations can she choose is 210.

You are looking at comparable houses with the same asking prices in neighboring towns. The mill rate in the first town is 20 mills. The mill rate in the second town is 37 mills. Both houses are assessed at $175,000. Mill rate is the tax rate that is applied to the assessed value of a real estate property by a municipality. Your tax is calculated by multiplying the mill rate by the assessed value of a property and dividing by 1,000. What is the dollar difference in annual property taxes based on mill rate between the two towns?

Answers

The  dollar difference in annual property taxes based on mill rate between the two towns is $2,975.

Dollar difference in annual property taxes

First step is to calculate for first town

First town=Mill rate÷1,000×Property assessed value

First town=20 mills÷1000×$175,000

First town=$3,500

Second step is to calculate for second town

Second town=Mill rate÷1,000×Property assessed value

Second town=37mills÷1000×$175,000

Second town=$6,475

Third step is to calulate the difference

Difference=$6,475-$3,500

Difference=$2,975

Inconclusion the  dollar difference in annual property taxes based on mill rate between the two towns is $2,975.

A 20 kg box rests on a table. What force does the earth exert on the box?

Answers

Answer:

The normal force acting on the body is equal to its weight, hence;

N = W = 196N

The normal force that the 20.0-kg box exerts on the 10.0-kg box is 98N

The formula for calculating the weight of an object is expressed as:

W = mg

m is the mass of the object

g is the acceleration due to gravity.

Given the following parameters

Mass of the box = 20.0kg

a) The weight of the box = 20 * 9.8

Weight of the box = 196N

Hence the weight of the  box is 196N

Note that the normal force acting on the body is equal to its weight, hence;

N = W = 196N

b) if a 10.0-kg box is placed on top of the 20.0-kg box, the total mass will be;

M = 10 + 20 = 30kg

total weight = 30 * 9.8

Total weight = 294N

Since the normal force is equal to the weight, hence W = N = 294N

Weight of the 10kg box = 10 * 9.8 = 98N

Since the 10kg box is on top of the 20kg box, hence the normal force that the 20.0-kg box exerts on the 10.0-kg box is 98N

Answers

From the calculation and data available in the question, the pH of the solution is 2.8 .

What is Kb?

The term Kb is used to refer to the base dissociation constant of a solution. Here we have the Kb as  1.7 × 10⁻⁹ but;

Ka = Kw/Kb = 1 * 10^-14/1.7 × 10⁻⁹ = 5.9 * 10^-6

We have to set up the ICE table as follows;

C        -x                                                    +x                      +x

E     0.420  - x                                            x                        x

Ka = [ C5H5NH] [H3O^+]/[C5H5NH^+]

5.9 * 10^-6 = x^2/ 0.420  - x

5.9 * 10^-6 (0.420  - x ) = x^2

2.478 * 10^-6 - 5.9 * 10^-6x = x^2

x^2 + 5.9 * 10^-6x - 2.478 * 10^-6 = 0

x=0.00157 M

Since;

[ C5H5NH] = [H3O^+] = x = 0.00157 M

pH = -log(0.00157 M)

Answers

10.00 mL of 0.4344 M vinegar solution is diluted to 50.00 mL. Then, 25.00 mL required 20.24 mL of 0.1073 M NaOH to reach the equivalence point.

What is titration?

Titration is the slow addition of one solution of a known concentration (called a titrant) to a known volume of another solution of unknown concentration until the reaction reaches neutralization, which is often indicated by a color change. In a broad sense, titration is a technique to determine the concentration of an unknown solution.

Step 1: Write the balanced neutralization equation.

NaOH + CH₃COOH = NaCH₃COO + H₂O

Step 2: Calculate the concentration of acetic acid that reacted with NaOH.

20.24 mL (Vb) of 0.1073 M (Cb) NaOH react with 25.00 mL (Va) of acetic acid of unknown concentration (Ca). We can calculate the concentration of the acid using the following expression.

Ca × Va = Cb × Vb

Ca = Cb × Vb / Va

Ca = 0.1073 M × 20.24 mL / 25.00 mL = 0.08687 M

Step 3: Calculate the initial concentration of acetic acid.

10.00 mL (V1) of acetic acid of unknown concentration (C1) is diluted to 50.00 mL (V2) of 0.08687 M (C2) acetic acid. We can calculate the initial concentration using the dilution rule.

C1 × V1 = C2 × V2

C1 = C2 × V2 / V1

C1 = 0.08687 M × 50.00 mL / 10.00 mL = 0.4344 M

10.00 mL of 0.4344 M vinegar solution is diluted to 50.00 mL. Then, 25.00 mL required 20.24 mL of 0.1073 M NaOH to reach the equivalence point.

What is right to work?

The term "right-to-work laws" refers to state laws in the United States that prohibit union security agreements between employers and labor unions that require employees.

By 1930, women in the United States had won the right to work, which meant they were legally permitted to work outside the home.

The right to vote, however, had already been secured with the ratification of the 19th Amendment to the United States Constitution in 1920.

Women were also allowed to join the military in 1948 and to run for office in 1916, though it took many more years for women to break down gender barriers in politics and achieve high-level political leadership roles.
