What is the area, in square inches, of the rectangle? Show your work!!

erma4kov [3.2K]

Answer:

$\huge\boxed{\sf 7 \frac{13}{20} \ in. ^2}$

Step-by-step explanation:

Length of the rectangle = $\displaystyle 2 \frac{1}{4} = \frac{9}{4} \ in.$

Width of the rectangle = $\displaystyle 3 \frac{2}{5} = \frac{17}{5} \ in.$

Area of the rectangle:

= Length × Width

$\displaystyle = \frac{9}{4} \times \frac{17}{5} \\\\= \frac{9 \times 17}{4 \times 5} \\\\= \frac{153}{20} \\\\= 7 \frac{13}{20} \ in.^2\\\\\rule[225]{225}{2}$

An auctioneer sold a herd of cattle whose minimum weight was 920 pounds, median was 1160 pounds, standard deviation 76, and I

katen-ka-za [31]

Answer:

minimum = $445

median = $565

standard deviation = $38

IQR = $48

Step-by-step explanation:

The minimum and the median are measures of location and are affected during addition (or subtraction) and multiplication (or division).

Satandard deviation and IQR (inter-quartile range), which are measures of dispersion, are affected by only multiplication (or division).

For the weight,

minimum = 920 pounds

median = 1160 pounds

standard deviation = 76 pounds

IQR = 96 pounds

For the price,

minimum = 0.50(920) - 15 = $445

median = 0.50(1160) - 15 = $565

standard deviation = 0.50(76) = $38............(Subtraction discarded)

IQR = 0.50(96) = $48........................................(Subtraction discarded)

Rashid [163]

Answer:

16.5 gallons per minute.

Step-by-step explanation:

The given table is:

$\begin{center}\begin{tabular}{ c c } Time(minutes) & Water(gallons) \\ 1 & 16.50 \\ 1.5 & 24.75 \\ 2 & 33 \\\end{tabular}\end{center}$

We are given this linear function in the form of table.

Let 't' be the time and W(t) be the function with which the gallons of water are changing with time.

We can use slope intercept form to find the equation.

$y=mx+c$

Slope of a function:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$x_2 = 1.5\\x_1 = 1\\y_2 = 24.75\\y_1 = 16.50$

$m=\dfrac{24.75-16.50}{1.5-1}\\\Rightarrow m =16.5$

This slope is the constant of proportionality.

i.e. the rate at which the number of gallons are changing per minute.

So, the answer is 16.5 gallons per minute.
