Seth has a garden with dimensions 9 feet long times 8 feet wide he wants to enlarge the garden to an area of 120 ft.² how much f

ziro4ka [17]

Answer:

6 ft longer (total length of 15ft)

Step-by-step explanation:

the initial dimensions are:

length: $l=9ft$

width: $w=8ft$

the area area of the garden is given by:

$a=l*w$

so the original area is:

$a=9ft*8ft=72ft^2$

Since we need the area to be $120ft^2$ , and we can only change the length, the width will still be 8ft.

We substitute the value of the new area and the width to the equation for the area:

$a=l*w\\120ft^2=l*8ft$

and we clear for the new length:

$l=\frac{120ft^2}{8ft}\\ \\l=15$

The length of the garden for the area to be $120ft^2$ , must be 15ft.

This means that if originally the length was 9 ft, now it has to be 6 ft longer.

An asset that costs $14,400 and has accumulated depreciation of $8,000 is sold for $5,600. What amount of gain or loss will be r

Advocard [28]

Answer:

There will be an $800 loss

Step-by-step explanation:

The initial cost of the asset is $14,400

When an asset depreciates, it loses its potential value over time. In this case, the total depreciation of our asset is given as $8,000.

The Current value of the asset = Initial Value - Accumulated Depreciation

Current value = $14,400 - $8,000 = $6,400

Since the asset is sold for $5,600, it is clear that this is a loss, as the selling price of $5,600 is less than the actual price of $6,400. So,

Loss = Actual (Cost) Price - Selling Price = $6,400 - $5,600 = $800

Identify the independent and dependent quantities from the function’s verbal description. What is the independent quantity, and

ad-work [718]

Question:

What is the independent quantity, and which variable should represent it?

Answer:

They're independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It's what changes as a result of the changes to the independent variable. An example of a dependent variable is how tall you are at different ages.

Explanation:

The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is the one that depends on the value of some other number. ... Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.
