The formula for the surface area of a rectangular prism is 2 (wl + hl + hw)

So first we multiply the width by the length.
12 x 4 = 48
Now we multiply the height by the length.
3 x 4 = 12
Now we multiply the height by the width.
3 x 12 = 36
Now we add all of our answers together.
48 + 12 + 36 = 96
And now we multiply it by 2.
96 x 2 = 192

So the surface area of the rectangular prism is 192.

Answer:

-$2.32

Step-by-step explanation:

Give that

The selling price per ticket is $9

And the number of tickets sold is 500

So,

There is one grand prize, three $300 second prize, and eleven $40 third prizes

We need to find out the expected value of the profit

$= \frac{1}{500} \times 2000 + \frac{3}{500} \times 300 + \frac{11}{500} \times 40\\\\$

= 4 + 1.8 + 0.88

= 6.68

Now the expected profit is

= $6.68 - $9

= -$2.32

Which equation models the problem below if c represents the number of puppies whose eyes are closed?

True [87]

First you must take into account the variable that is being defined for this case:
c = represents the number of puppies whose eyes are closed.
We can then write the following equation:
15 = 11 + c
Rewriting the equation:
11 + c = 15
Clearing c:
c = 15-11
c = 4
4 puppies have their eyes closed
Answer:
11 + c = 15
4 puppies have their eyes closed
