Hmm... I was too lazy to illustrate. So that is why you have asked. I had that question too.

There are 8 faces on the longer face and 4 faces on the shorter face.

3308.33

ok then. Let's say I start with $50 instead of $30. What will happen?

Properties:

A number divisible by 2 is even.

A number divisible by 3 has the sum of digits that can be divided exactly by 3.

A number divisible by 5 ends with either 5 or 0.

A number divisible by 6 is divisible by 2 and 3.

A number divisible by 9 has the sum of digits that can be divided exactly by 9.

A number divisible by 10 ends with 0.

It is NOT divisible by 2,3,5,6,9,10.

I meant find the volume of the rectangular prism.

Let's solve for option A first.

x = -6

y = -14

(7 * -6) - (5 * -14) = 28

(-42) - (-70) = 28

(-42) + 70 = 28

70 - 42 = 28

A is true.

Now for B.

x = -1

y = -7

(7 * -1) - (5 * -7) = 28

(-7) - (-35) = 28

35 - 7 = 28

B is true.

Then C.

x = 4

y = 10

(7 * 4) - (5 * 10) = 28

28      - 50          = 28

-22                     = 28

-22                     ≠ 28                        

So C is false.

Last of all, D.

x = 7

y = 9

(7 * 7) - (5 * 9) = 28

49       -  45     = 28

4                     = 28

4                     ≠ 28 

And D is false, too.

So the only solutions for (x,y) is A and B.

Red Die

Odd numbers: 1, 2, 3, 4, 5, 6

Probability: 3 / 6 = 1 / 2

Green Die

Perfect Squares: 1, 2, 3, 4, 5, 6

1 is a perfect square as √1 = 1

4 is a perfect square as √4 = 2

Probability: 2 / 6 = 1 / 3

1 / 2 * 1 / 3 = 1 / 6

99 / 333 = 33 / 111

              = 11 / 37

Circumference of patio = dπ

                                     = 15π feet

                                     = 15 * 3.142 feet (taking π = 3.142)

                                     = 47.13 feet

What do you mean by "concrete"? If we are asked if Al has enough budgeted for the patio, then we must find the height of the patio!!

I will now assume that the height of the patio is h feet.

47.13 * h = 47.13 h square feet

47.13 h square feet * $0.32 ≈ $15.08 h

If :

$15.08 h > $215, then Al doesn't have enough money budgeted.

If:

$15.08 h ≤ $215, then he has enough money budgeted.
