A box is 3 inches by 2 feet by 10 yards. How many cubic inches are in the box? How many cubic yards are in the box? (Show all wo
IceJOKER [234]

Answer:

There are <u>25920</u> cubic inches and <u>0.56</u> cubic yards in the box.

Step-by-step explanation:

Given:

The dimensions of the box are 3 in by 2 ft by 10 yd.

Convert all in inches.

We know that, 1 ft = 12 in

So, 2\textrm{ ft} = 2\times 12 = 24\textrm{ in}

Also, 1 yd = 36 in

So, 10\textrm{ yd} = 10\times 36 = 360\textrm{ yd}

Now, volume of the box in cubic inches is given as:

V=3\times 24\times 360=25920\textrm{ }in^{3}

Now, we know that,

1\textrm{ in} = \frac{1}{36}\textrm{ yd}\\1\textrm{ }in^{3}=\frac{1}{36^{3}}\textrm{ }yd^{3}

Therefore,

25920\textrm{ }in^{3}=25920\times \frac{1}{36^{3}}= 0.56\textrm{ }yd^{3}

So, there are <u>25920</u> cubic inches and <u>0.56</u> cubic yards in the box.

Answer:

See below.

Step-by-step explanation:

1)

So we have the equation:

2x+3y=1470

To change into the slope-intercept form, we need to isolate the y-variable. Thus, subtract 2x from both sides:

(2x+3y)-2x=(1470)-2x

The left side cancels:

3y=1470-2x

Now, divide both sides by 3. The left side cancels:

(3y)/3=(-2x+1470)/3\\y=-\frac{2}{3} x+490

The slope-intercept form is:

y=mx+b

Where m is the slope and b is the y-intercept.

Thus, the slope is -2/3 and the y-intercept is 490.

2)

So, since we already know the y-intercept is 490, plot a point at (0,490).

The slope is too small to use. Thus, multiply the fraction by 100. It is now (-200/300). This means that we move <em>down</em> 200 for every 300 (recall that the slope means rise over run. Thus, we move down 200 for every 300 to the right). Thus, another possible point would be (0+300,490-200) or (300,290). Plot that. Then, connect them.

3)

To write in in function notation, simply substitute the y-variable for the function notation. Our independent variable here is x so we'll use that.

y=-\frac{2}{3}x+490\\ f(x)=-\frac{2}{3}x+490

This means that for every x sandwiches made, there is f(x) wraps made for the total sum to be $1,470.

For example, if 105 sandwiches were made, then f(105)=-2/3(105)+490=420 wraps were made for the total profit to be $1,470.

4)

Please refer to the attached graph.

5)

First, since the total profit has now increased, the graph above and to the right of the old graph. This is because Sal needs to sell more sandwiches and wraps. Likewise, because of this, the x- and y-intercepts will also be different. Nevertheless, if converted into the slope-intercept equation, the slope will remain the same.
