Linda is planning to build a rectangular deck that is 12 feet longer than it is wide. Find its width if its area is 589 square feet. Write an equation that models this problem?

Answers

Answer 1

Answer: Let the width be x, then the length is x + 12.
Area = length x width = x(x + 12) = 589
$x^(2) +12x = 589$
Solving the quadratic equation, we have that
x = 19 feet
i.e. the width is 19 feet.

If a models barn door is 2 and 1 quarter inches high , how high is the actual barn door ?

Answers

The easiest way to solve this is to use a proportion
but first, make the 2 1/4 into a decimal. 1/4 equals .25
$(2.25)/(x) = (1)/(48)$

use butterfly method or cross mulitply to solve.
[tex]1*x=2.25*48

x=108

the barn door in real life is 108 inches

Round to the hundredths place. 1.21 0.93 40.98 40.22

Answers

The difference between mean with outlier and mean without outlier is 0.93

Step-by-step explanation:

Total months are 12

So,

n=12

Sum of all values = 493.78

The mean is given by:

$Mean=(Sum\ of\ values)/(No.\ of\ values)\n=(493.78)/(12)\n=41.148\ minutes$

The mean with outlier is: 41.148

Now to calculate the mean without outlier

We will subtract the outlier value from total sum

The outlier is 51.32 so the new sum will be: 493.78-51.32 =442.46

Total number of values = 12-1 = 11

The mean without outlier will be:

$Mean\ without\ outlier=(442.46)/(11) =40.223$

Now the difference between both means is:

$41.148-40.223=0.925 => 0.93$

The difference between mean with outlier and mean without outlier is 0.93

Answer:

- 5x - 15

Step-by-step explanation:

Given

- 5(x + 3)

Each term in the parenthesis is multiplied by the - 5, that is

= (- 5 × x) + (- 5× 3)

= - 5x + (- 15)

= - 5x - 15

To solve this, all we need to do is substitute the values of x and y at which they are the same into each equation and see if it holds true.

A. $(y)/(x) = (1)/(2)$

$(-8)/(4) = (1)/(2)$

$-2 = (1)/(2)$

Since this is not true, we can scratch choice A off our list.

B. $(y)/(x) = -2$

$(-8)/(4) = -2$

$-2 = -2$

This is true, so choice B is one of the correct answers.

C. $-2x = y$

$-2 (4) = -8$

$-8 = -8$

This equation also holds true, so choice C is also correct, but let us do the final option just for the sake of completion.

D. $x = 2y$

$4 = 2 (-8)$

$4 = -16$

This is obviously not true, so choice D is also false.

The correct answer choices are B and C.
Hope that helped! =)

varies directly, so x times a number = y
let z be that number
y= zx
-8=4z
z=-2
y=-2x
which is equals to y/x=-2 and -2x=y , so its B and C
