$\bf \begin{array}{ccll} ft^2&minute\\ \cline{1-2} 50&\frac{1}{5}\\\\ x&6 \end{array}\implies \cfrac{50}{x}=\cfrac{~~\frac{1}{5}~~}{6}\implies \cfrac{50}{x}=\cfrac{~~\frac{1}{5}~~}{\frac{6}{1}}\implies \cfrac{50}{x}=\cfrac{1}{5}\cdot \cfrac{1}{6} \\\\\\ \cfrac{50}{x}=\cfrac{1}{30}\implies 1500=x$

Answer:

60 square feet.

Step-by-step explanation:

Given : a water pipe leak floods 50 square feet every 1/5 minute.

To find : what is the flooded area after 6 minutes.

Solution : We have given

In $\frac{1}{5}$ minute water pipe leak flood = 50 square feet.

In 1 minute water pipe leak flood = 50 * $\frac{1}{5]$ .

In 1 minute water pipe leak flood = 50 * $\frac{1}{5}$ * 6 square feet.

In 1 minute water pipe leak flood = 10 * 6 square feet.

In 1 minute water pipe leak flood = 60 square feet.

Therefore,

60 square feet.

Which equation is equivalent to 2/3x-5/6=-5/12x+1/4

umka21 [38]

Answer:

x = 1

Step-by-step explanation:

$\frac{2}{3} x - \frac{5}{6} = - \frac{5}{12} x + \frac{1}{4} \\ \frac{2}{3}x + \frac{5}{12} x = \frac{1}{4} + \frac{5}{6} \\ \frac{8}{12} x + \frac{5}{12}x = \frac{3}{12} + \frac{10}{12} \\ \frac{13}{12} x = \frac{13}{12} \\ x = 1$

The measure of dispersion that measures how much the data differ from the mean is called the.

Alenkinab [10]

The measure of dispersion that measures how much the data differ from the mean is called the standard deviation.

<h3>What is standard deviation?</h3>

Standard deviation is a statistical measure of dispersion as opposed to the measure of central tendency like mean, median and mode.

The standard deviation is a measure of how spread out data values are around the mean.

It is defined as the square root of the variance and represented with the Greek letter σ.

Gabby and Sydney bought some pens and pencils. Gabby bought 4 pens and 5 pencils for $6.71. Sydney bought 5 pens and 3 pencils f

denpristay [2]

Answer:

The cost of each pens is $1.19

The cost of each pencils is $0.39

Step-by-step explanation:

Given as :

The number of pens bought by Gabby = 4

The number of pencils bought by Gabby = 5

The number of pens bought by Sydney = 5

The number of pencils bought by Sydney = 3

The total cost of Gabby items = $6.71

The total cost of Sydney items =$7.12

Let The cost of each pens = x

And The cost of each pencils = y

Now, According to question

For Gabby

4 x + 5 y = $6.71 .............1

For Sydney

5 x + 3 y = $7.12 .............2

Now, Solving both equations

5 × (4 x + 5 y) - 4 × (5 x + 3 y) = 5 × 6.71 - 4 × 7.12

Or, 20 x + 25 y - 20 x - 12 y = 33.55 - 28.48

Or, (20 x - 20 x) + (25 y - 12 y) = 5.07

or, 0 + 13 y = 5.07

∴ y = $\frac{5.07}{13}$

I.e y = $0.39

So, The cost of each pencils = y = $0.39

Again , put The value of y in eq 1

I,e 4 x + 5 y = $6.71

Or, 4 x + 5 × 0.39 = 6.71

or, 4 x + 1.95 = 6.71

or, 4 x = 6.71 - 1.95

or , 4 x = 4.76

∴ x = $\frac{4.76}{4}$

I.e x = $1.19

The cost of each pens = x = $1.19

Hence The cost of each pens is $1.19

And The cost of each pencils is $0.39 Answer
