find the surface area of the rectangular prism that is 16 inches long, 12 inches wide, and 5 inches in length

2 answers:

<span>Surface Area of a closed rectangular Prism equals to twice the area of the base plus the perimeter of the base multiplied by the height.

In your question:

Area of the base = (16)(12) = 192

Twice the Area of the base = 2(192) = 384

Perimeter of the base = 2(16) + 2(12) = 56

Surface Area = Twice the Area of the base + the Perimeter of the base x height

S.A. = 384 + 56 x 5
</span>
The surface area is 664 <span>in². Hope that helps.</span>

The table compares the prices of four types of fruit. Which fruit is the best to buy?

taurus [48]

Divide the price by the quantity:

Bananas = 5.40 / 6 = 0.90 each

Oranges = 2.56/8 = 0.32 each

Apples = 4.68 / 12 = 0.39 each

Mangos = 3.16 / 4 = 0.79 each

Oranges have the lowest price each so are the best buy.

Find an equation for the line below. Thanks !

daser333 [38]

Answer:

$\huge\boxed{y=\frac{1}{4}x + \frac{13}{4}}$

Step-by-step explanation:

In order to find the equation to this line, we need to note that we see two points on this graph. Using these two points, we can use them to find the slope of the graph and use one to find the y-intercept.

We know that the slope of a line is defined by $\frac{\Delta y}{\Delta x}$ (change in y / change in x). Therefore, we can use our two points that we know - (-5, 2) and (3, 4) to find the slope.

The change in y is $4 - 2 = 2$ , and the change in x is $3 - (-5) = 3+5= 8$ . Therefore, our slope is $\frac{2}{8} = \frac{1}{4}$ .

Now that we know our slope, our equation in slope-intercept form looks something like this.

$y = \frac{1}{4}x + b$

However, we still have b to solve for. We can solve for this by substituting a point we already know into the equation. Let's substitute (3, 4) inside.

$4 = \frac{1}{4} \cdot 3+b$
$4 = \frac{3}{4} + b$
$b = \frac{16}{4}- \frac{3}{4}$
$b = \frac{13}{4}$

So now we know that the y-intercept is $\frac{13}{4}$ . Plugging that into our equation finishes it off, leaving our final equation to be $y = \frac{1}{4}x + \frac{13}{4}$ .

Hope this helped!

babymother [125]

P= 3000 (1.21)^t, t= time in months

1 year = 12 months, and therefore, 1 month = 1/12 years

The equation showing yearly population growth changes to;

P=3000 (1.21)^t/12

The correct answer is equation [1].
