For part A, the answers are:
38.76
13.875
7.0
9.779

For part B, just add all the costs.

For part C, the answer is:
You solve it trying Mr. Lowe's equation, you should get 75.0318.
To fill the empty box, what you need to do is tell them why his answer is right or why it's wrong. I am doing it for you, you should fill that box with:

Mr. Lowe's equation was wrong because he added the numbers that have to be multiplied, and he multiplied the numbers that must be added.
The right equation is:
(10.2 × 3.80) + (12.5 × 1.18) + (6.25 × 1.12) + (8.89 × 1.10) = 70.289

Hoochie [10]

Let's say you wanted to earn a yield of 8%. $210,000 x .31524 = $66, 200.4 +$10,500 x 8.55948 = $89, 874.54 Use the tables to find .31524 (which is 8% @ 15 periods for present value of 1) and 8.55948 (which is 8% @ 15 periods for present value of an ordinary annuity of 1) You would pay a total of $156, 074.94

Two fair cubes, numbered 1 through 6, are tossed at the same time in order to advance on a game board. What is the probability t

DaniilM [7]

If the cubes are rolled independently, and assuming any face on the cube is as likely to occur as any other, then there is a 1/6 probability of rolling a 6, and rolling a 6 on both simultaneously is 1/6 * 1/6 = 1/36.

Answer:

The volume of P is 1728 cubic yards.

Step-by-step explanation:

For similar shapes, the ratio of volumes are defined as:

$\frac{V_{1} }{V_{2}}$ = $(\frac{h_{1} }{h_{2}}) ^{3}$

where h1 and h2 are the heights of each pyramid respectively.

We know that the scale factor of P to Q is 6:1 i.e. the ratio of heights is also 6:1. And the volume of Q is given as 8 cubic yards. so, using the relation defined above we can write:

$\frac{V_{P} }{V_{Q}}$ = $(\frac{h_{P} }{h_{Q}}) ^{3}$

$\frac{V_{P} }{8}$ = $(\frac{6}{1} )^{3}$

Vp = 6³ * 8

= 216 * 8

Vp = 1728 cubic yards

The volume of P is 1728 cubic yards.
