Elle and heather drew floor models of there living rooms.Elles model respresented 20 feet by 15 feet.Heathers model respresented

ludmilkaskok [199]

Answer:

Heather's model represents the greater area.
$24\ ft^2$ greater.

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=lw$

Where "l" is the lenght of the rectangle and "w" is the width.

The formula for calculate the area of a square is:

$A=s^2$

Where "s" is the side lenght.

In this case, knowing that Elle's model represented 20 feet by 15 feet, we can say that:

$l=20\ ft\\w=15\ ft$

Therefore, substituting these values into the formula $A=lw$ , we get that the area is:

$A_1=(20ft)(15ft)=300\ ft^2$

Since Heather's model represented 18 ft by 18 feet, we can identify that:

$s=18ft$

Substituting this value into $A=s^2$ , we get this area:

$A_2=(18ft)^2=324\ ft^2$

Notice that Heather's model represents the greater area.

To calculate how much greater it is, subtract the areas. Then:

$324\ ft^2-300\ ft^2=24\ ft^2$

The length of the hypotenuse of a right triangle is 16 inches. If the length of one leg is 5 inches, what is the approximate len

Musya8 [376]

Answer:

15.2 inches

Step-by-step explanation:

a^2 + b ^2= c^2

5^2 + b ^2=16^2

b ^2=256 - 25

√b ^2=√231

b= 15.2 inches

A movie-theater employee notes an inverse relationship between the theater's popcorn sales and its nacho sales. On a given night

mario62 [17]

Using proportions, it is found that $1,225 is earned from nachos.

This question is solved by <em>proportions</em>, using a rule of three.

The measures have an inverse relationship, hence line multiplication is applied instead of cross multiplication.

When the theater makes $1,540 from popcorn sales, it makes $1,330 from nacho sales. How much is earned from nachos when $1,672 is earned from popcorn?

The <em>rule of three</em> is:

$1,540 - $1,330

$1,672 - $x

Applying line multiplication:

$1672x = 1540 \times 1330$

$x = \frac{1540 \times 1330}{1672}$

$x = 1225$

$1,225 is earned from nachos.

Evaluate 20.003+[(30.1+5.75)-6.87

Amanda [17]

Answer:

48.983.

Step-by-step explanation:

(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).

Using order of operations (PEMDAS):

20.003 + [(30.1 + 5.75) - 6.87] Work out the inner parentheses first:

= 20.003 + [35.85 - 6.87] Now the outer parentheses:

= 20.003 + 28.98

= 48.983.

Calculate the mean, median and mode of the following data.

garik1379 [7]

Answer:

d.mean =15, median =15.5, mode = 16

Step-by-step explanation:

hello,

to find the mean, you add all the numbers together and divide it by the total number of numbers. so that would be 150 (total sum) divided by 10 (number of numbers) to get 15.

to find the median, you would organize the numbers from least to greatest and find the middle number which is 15.5.

last but not least, to find the mode, just look for the number that appears most often. Therefore, the mode would be 16.

hope this helped!
