Answer: \dfrac{1}{5}\text{ of an ounce.}

Step-by-step explanation:

Given : A biologist studied how cells grow by adding liquid protein to cell samples.

She divided \dfrac{3}{5} of an ounce of liquid protein evenly among 3 cell samples.

Here , total quantity of liquid protein = \dfrac{3}{5} of an ounce

Total cell samples = 3

Now , Quantity of liquid protein given by her to each cell = (total quantity of liquid protein ) ÷ (3)

= \dfrac{3}{5}\times\dfrac{1}{3}=\dfrac{1}{5}\text{ of an ounce} .

Hence, Quantity of liquid protein given by her to each cell =  \dfrac{1}{5}\text{ of an ounce.}

I ran 8kilometers in 20 minutes that cost me $10 how many miles would it be if cost is $30
Nata [24]

Answer:

14.91288  miles

Step-by-step explanation:

We can use a proportion to solve this problem.  Put the distance over the cost.  We want our answer in miles so we need to convert 8 kilometers to miles.   1 km = .621371 miles

8 km * .621371 miles/ 1 km = 4.971 miles


4 .971 miles          x miles

--------------------- = ------------------

10 dollars               30 dollars


Using cross products

4.971 * 30 = 10x

149.1288= 10 x

Divide by 10 on each side

149.1288/10= 10/10 x

14.91288 =x

Put the following items in order from most expensive to least expensive. Item Base Price Change Direction Blender $29. 73 9% Mar
Furkat [3]

Putting the considered items in order from most expensive to least expensive item gives the order as shown by: Option b. Blender, ink, hat, heater

<h3>What is Markup and Markdown?</h3>

Markup is the amount that will be increased in the original price of the considered thing.

Markdown is the amount that will be decreased from the original price of the considered thing.

Think of "up" and "down" as increasing and decreasing prices respectively.

<h3>How to find the percentage from the total value?</h3>

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

\dfrac{a}{100} \times b

For this case, the base prices and the chage in price is given as:

Item                Base Price                    Change Direction

Blender            $29.73                           9% Markdown

Hat                   $14.16                             77% Markup

Ink                    $20.17                            27% Markup

Heater             $28.46                           22% Markdown

Calculating the resultant price:

  • Case 1: Blender:

Resultant price = 29.73 - 9% of 29.73

P= 29.73 - \dfrac{29.73}{100}\times 9\\\\P = 27.0543 \: \: \text{dollars}

  • Case 2: Hat:

Resultant price = 14.16 + 77% of 14.16

P= 14.16+\dfrac{14.16}{100}\times 77\\\\P = 25.0632\: \: \text{dollars}

  • Case 3: Ink:

Resultant price = 20.17 + 27% of 20.17

P= 20.17+\dfrac{20.17}{100}\times 27\\\\P = 25.6159\: \: \text{dollars}

  • Case 4: Heater:

Resultant price = 28.46 - 22% of 28.46

P= 28.46- \dfrac{28.46}{100}\times 22\\\\P = 25.0448 \: \: \text{dollars}

Thus, putting the considered items in order from most expensive to least expensive item gives the order as shown by: Option b. Blender, ink, hat, heater
