Adam is planning a party for his daughter, Rachel. The party has a beach theme. Adam plans to fill a sandbox with fresh sand so

the kids can build sandcastles. The sandbox is twelve feet long and two feet tall. The width of the sandbox is half of its length. What is the volume of sand needed to fill the sandbox?

Answer:

Volume = 144 ft

Step-by-step explanation:

1. Let's write some things down, so we don't forget them!

Length = 12 ft

Height = 2 ft

Width = 6 ft

2. We can probably assume the sandbox is a rectangle. The formula for the volume of a rectangle is Length x Height x Width. So, 12 x 2 x 6 = 144, therefore that's the volume!

Which equations represent the line that is perpendicular to the line 5x − 2y = −6 and passes through the point (5, −4)? Select t
nignag [31]

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

On the other hand we have that if two lines are perpendicular, then the product of their slopes is -1. So:

m_ {1} * m_ {2} = - 1

The given line is:

5x-2y = -6\\-2y = -6-5x\\2y = 5x + 6\\y = \frac {5} {2} x + \frac {6} {2}\\y = \frac {5} {2} x + 3

So we have:

m_ {1} = \frac {5} {2}

We find m_ {2}:m_ {2} = \frac {-1} {\frac {5} {2}}\\m = - \frac {2} {5}

So, a line perpendicular to the one given is of the form:

y = - \frac {2} {5} x + b

We substitute the given point to find "b":

-4 = - \frac {2} {5} (5) + b\\-4 = -2 + b\\-4 + 2 = b\\b = -2

Finally we have:

y = - \frac {2} {5} x-2

In point-slope form we have:

y - (- 4) = - \frac {2} {5} (x-5)\\y + 4 = - \frac {2} {5} (x-5)

ANswer:

y = - \frac {2} {5} x-2\\y + 4 = - \frac {2} {5} (x-5)

Solve for m.<br> 8m+95&lt;−87m+5
tiny-mole [99]

Answer:

m < -\frac{18}{19}

Step-by-step explanation:

8m + 95 < -87m + 5

8m + 87m < 5 - 95

95m < -90

m < -<u>\frac{90}{95}</u>

Simplifying gives;

m < -\frac{18}{19}

Name the property of real numbers illustrated by the equation -3(x + 4) = -3x -12
vivado [14]

Answer:

Distributive Property

Step-by-step explanation:

They distributed the -3 to x and 4. In this case, to distribute the -3, you multiply it to each term.

-3 × x = -3x.

-3 × 4 = -12.

-3x - 12
