Answer:

the bottle will last approximately 12.5 days if the patient takes 2 teaspoons (10 mL) of Mucinex 4 times a day as ordered.

Step-by-step explanation:

Assuming that one teaspoon is equivalent to 5 milliliters (mL), then 2 teaspoons would be 10 mL. Therefore, the patient will be taking a total of 10 mL four times a day, which is 40 mL per day.

Since the bottle contains 500 mL, we can calculate how long the bottle will last by dividing the total volume of the bottle by the daily dose:

Number of days = Total volume of bottle / Daily dose

Number of days = 500 mL / 40 mL per day

Number of days = 12.5 days

Therefore, the bottle will last approximately 12.5 days if the patient takes 2 teaspoons (10 mL) of Mucinex 4 times a day as ordered.

Step 1: To convert 1.33 repeating into a fraction, begin writing this simple equation:

n = 1.33 (equation 1)

Step 2: Notice that there are 2 digitss in the repeating block (33), so multiply both sides by 1 followed by 2 zeros, i.e., by 100.

100 × n = 133.333 (equation 2)

Step 3: Now subtract equation 1 from equation 2 to cancel the repeating block (or repetend) out.

100 × n = 133.333

 1 × n = 1.33

99 × n = 132

132

99

could be the answer, but it still can be put in the simplest form, i.e., reduced.

To simplify this fraction, divide the numerator and denominator by 33 (the GCF - greatest common factor).

n = 132

99

= 132 ÷ 33

99 ÷ 33

= 4

3

. So, 1.33 = 4/3

as the lowest possible fraction.

Answer:

Please mark as brainliest

Miguel has to put up the equation r = 72/16.

4.5% is the interest rate.

For calculating how long it would take for an investment to double in value, the rule of 72 is utilised. To get the doubling time, divide 72 by the interest rate.

To use the rule of 72, you simply divide the number 72 by the annual interest rate. For example, if the interest rate is 6%, the rule of 72 predicts that it will take approximately 12 years (72 ÷ 6 = 12) for the investment to double in value.

Part2:

equation can Miguel set up to solve for the annual interest rate he needs to double his money by the time he retires is n = 72 / r

Part3:

annual interest rate does Miguel need to double his money by the time he retire

r = 72 / n

72 / 16 = 4.5%

The z-value for a chance of 0.20 in the right tail of the distribution can be found using a calculator or a standard normal distribution table.

The probability number in the right tail that is

=> closest to 0.20 using a standard normal distribution table is 0.1995.

This probability's equivalent z-value is roughly 0.84.

As an alternative, we can calculate the z-value using a computer. With a chance of 0.20, a mean of 0, and a standard deviation of 1, and the inverse normal function—also known as the normal quantile function—we obtain:

=> Z=invNorm(0.20) 0.84

As a result, the z-value at which a large z value is obtained with a 0.20 chance is roughly 0.84.

The probability that out of 8 workers, 3 will ride in carpools is 0.254.

What is probability?

The mathematical concept of probability is used to determine the likelihood of an event. It is solely useful for calculating the probability that an event will occur. From 0 to 1, where 0 represents impossibility and 1 represents a particular occurrence.

We are given that 30% of all commuters ride to work in carpools.

Now, if eight workers are selected, then the probability that three will ride in carpools is determined by using the following

P (X = 3) = [tex]n C_{x} p^{x} (1-p)^{(n-x)}[/tex]

We have n = 8, x = 3 and p = 0.3

So, using the formula, we get

⇒P (X = 3) = [tex]8 C_{3} (0.3)^{3} (1-0.3)^{(8-3)}[/tex]

⇒P (X = 3) = [tex]8 C_{3} (0.3)^{3} (0.7)^{(5)}[/tex]

⇒P (X = 3) = 56 *  [tex](0.3)^{3} (0.7)^{(5)}[/tex]

⇒P (X = 3) = 56 * 0.027 * 0.16807

⇒P (X = 3) = 0.254

Hence, the probability that out of 8 workers, 3 will ride in carpools is 0.254.

Hello and greetings KingDanny2xx.

Therefore, the inverse of f(x)=2x+3/5 is f⁻¹ (x) = x/2 - 3/10.

 [tex]\boldsymbol{\sf{f(x)=2x+\dfrac{3}{5} }}[/tex]

We substitute f(x) for y.

          [tex]\boldsymbol{\sf{y=2x+\dfrac{3}{5} }}[/tex]

We interchange x and y.

       [tex]\boldsymbol{\sf{x=2y+\dfrac{3}{5} }}[/tex]

We interchange the sides of the equation. We want to swap sides because mathematicians agreed to the convention that the unknown variable in equations and inequalities must always be on the left-hand side.

If there is a variable on both sides, we do it to facilitate a later calculation.

        [tex]\boldsymbol{\sf{2y+\dfrac{3}{5}=x }}[/tex]

We multiply both sides of the equation by 5. We want to multiply an equation to get rid of fractions and/or rational expressions, doing a lot more calculations later.

Both sides of the equation must be multiplied by the same value to preserve equality between all sides, according to the Multiplication Property of Equality.

        [tex]\boldsymbol{\sf{5\left(2y+\dfrac{3}{5}\right)=5x }}[/tex]

We distribute the 5 to the terms in parentheses. The distributive property is that each term in an expression between parentheses is multiplied by the expression outside the parentheses.

          [tex]\boldsymbol{\sf{5x2y+5x\dfrac{3}{5} =5x}}[/tex]

We calculate the product.

            [tex]\boldsymbol{\sf{10y+\not{5}x\dfrac{3}{\not{5}}=5x }}[/tex]

We cancel the greatest common divisor 5.

            [tex]\boldsymbol{\sf{10y+3=5x}}[/tex]

We move the constant to the right side and change its sign. We want to move a constant to the right because it is customary for constants in equations to be on the right hand side.

The sign of the constant must be changed because in the process of "moving the constant", we are adding its opposite to both sides.

We move the constant to the right by adding its opposite to both sides.

     [tex]\boldsymbol{\sf{10y+3-3=5x-3}}[/tex]

Since two opposite numbers add up to 0, we remove them from the expression. The additive inverse property states that two opposite numbers add up to 0.

Since adding or subtracting 0 doesn't change the value of the expression, we can simply remove them.

      [tex]\boldsymbol{\sf{10y=5x-3}}[/tex]

We divide both sides of the equation by 10. We want to divide an equation to isolate the unknown variable on one side or to transform the equation in a certain way.

Both sides of the equation must be divided by the same number to preserve equality between the sides, according to the Division Property of Equality.

         [tex]\boldsymbol{\sf{10y\div10=(5x-3)\div10}}[/tex]

Any equation divided by itself is equal to 1.

         [tex]\boldsymbol{\sf{y=(5x-3)\div10}}[/tex]

We distribute the 10 to the terms in parentheses. The distributive property is that each term of an expression between the parentheses is multiplied by the expression that is outside the parentheses.

        [tex]\boldsymbol{\sf{y=5x\div10-3\div10 }}[/tex]

We write the division as a fraction. A fraction is another way of writing division.

One more way to remember it is the division symbol.

We notice that the division symbol looks like a fraction where the dots represent the numerator and denominator.

         [tex]\boldsymbol{\sf{y=\dfrac{5}{10}x-3\div10 \iff y=\dfrac{\not{5}}{\not{10}}x-\dfrac{3}{10} }}[/tex]

We divide by the common factor 5. The object of canceling a common factor is to rewrite a fraction in the simplest form to facilitate a later calculation.

We can cancel a common factor because it will still represent the same value.

         [tex]\boldsymbol{\sf{y=\dfrac{1}{2}x-\dfrac{3}{10} }}[/tex]

Substitute y for f⁻¹ (x). Substitution means to replace one algebraic expression with another or with a specific value.

         [tex]\boldsymbol{\sf{f^{-1}(x)=\dfrac{x}{2}-\dfrac{3}{10} }}[/tex]

Therefore, the inverse of f(x)=2x+3/5 is f⁻¹ (x) = x/2 - 3/10.

Answer:

3 final songs

Step-by-step explanation:

Answer: There will be 3 songs on the final CD.

Step-by-step explanation: The band expects to put 12 songs on their next CD. They write and record 25% more songs than they expect, which means they wrote and recorded 12 + (0.25 x 12) = 15 songs. During the editing process, 80% of the songs are removed. 80% of 15 is (0.80 x 15) = 12 songs. Subtracting the removed songs from the recorded songs, we get 15 - 12 = 3 songs that will be on the final CD. Therefore, there will be 3 songs on the final CD.

To determine if the job is complete, we need to add up the fractions of the decoration that each person put up:

Anna: 2/5

Manna: 1/4

Hanna: 3/10

Now we can find the total fraction of the decoration that they put up by adding these fractions:

2/5 + 1/4 + 3/10 = 16/40 + 10/40 + 12/40 = 38/40

So they have completed 38/40 of the decoration. To find the fraction of the job that is still left to do, we can subtract this from 1:

1 - 38/40 = 2/40

Therefore, there is still 2/40 of the decoration left to do, or 1/20 of the total job.

There would be $2203.50 in Stony's account by September 2020 using simple interest formula.

As the bank charges an annual 8% simple interest, we may apply the following formula:

Simple interest is calculated as follows: Principle is the initial investment, Rate is the annual interest rate, and Time is the duration in years.

Here, the principal (P) is $1575, the interest rate (r) is 8%, and the time (t) is 5 since we need to know how much money Stony will have in his account by September 2020, which is five years from now.

We may calculate Stony's interest earnings over a five-year period using the simple interest formula:

Interest is calculated as follows: $1575 x 0.08 x 5 = $628.50

Stony's account will therefore have the following balance by September 2020: Total Amount = Principal + Interest = $1575 + $628.50 = $2203.50

Therefore by September 2020, Stony would have $2203.50 in his account.

y = $100.00 - $10.00x is the equation for the total amount of money in the savings account after x weeks.

The y-intercept represents the initial deposit of $100.00 and the slope is -10

a. Let's call the amount of money saved each week "s" and

let's call the total amount of money in the savings account after "x" weeks "y".

Since the amount saved each week is the same, we can express the total amount of money in the savings account as:

y = $100.00 + sx

We know that at the end of the 5th week, the total amount in the savings account is $50.00. So we can set up the following equation:

$50.00 = $100.00 + 5s

solving for s:

$50.00 - $100.00 = 5s

-$50.00 = 5s

-10 = s

So the equation for the total amount of money in the savings account after x weeks is:

y = $100.00 - $10.00x

b. In the context of this problem, the slope represents the amount of money that is saved each week.

In this case, the slope is -10, meaning that $10.00 is saved each week. The y-intercept represents the initial deposit of $100.00.

The difference between  the Statue of Liberty compared to other outdoor statues is that it is made of copper which is option C.

The Statue of Liberty is a colossal neoclassical sculpture located on Liberty Island in New York Harbor in the United States. It was a gift from the people of France to the people of the United States, dedicated on October 28, 1886, and has since become one of the most recognizable symbols of the United States and its ideals of freedom and democracy.

The statue was designed by French sculptor Frédéric-Auguste Bartholdi, with the help of engineer Gustave Eiffel. The statue depicts a female figure dressed in a flowing robe and holding a torch in one hand and a tablet in the other, upon which is inscribed the date of the American Declaration of Independence (July 4, 1776).

The Statue of Liberty is unique among outdoor statues in that it is made of copper sheets that have oxidized over time to form a green patina. This patina has become an iconic symbol of the statue and is a result of the natural process of copper corrosion. The statue was originally a shiny brown color, but the oxidation of the copper has gradually changed its appearance over time.

Therefore, while the Statue of Liberty is also located in a park and on a pedestal, and it is larger than many outdoor statues, these characteristics are not unique to the statue and can be found in other outdoor statues as well.
