The Harris family needs to purchase topsoil for their landscaping project (measuring 50 ft x 40 ft with a thickness of 6 inches

of topsoil/mulch). They have two options:
a. purchasing the soil in 3 ft3 bags priced at $2.25 each with no delivery charge, or
b. purchasing in bulk at $18 per cubic yard with a one-time $50 delivery fee. Which option is the least expensive and by how much? Explain.

50ft x 40ft x 0.5ft = 1,000 ft³ of soil needed for the project

1000/3= 333.3 bags of soil would be needed, so round up to 334.
334 x $2.25 = $751.50

convert the feet³ to yards³, divide the 1000 ft³ by 27 (27 ft³ in 1 yard³)
1000/27= 37.037(repeating) yd³ I'll round up to 38 yd³
38yd³ x $18 = $684 + $50 delivery fee = $734

So, the bulk soil is less expensive by $17.50

Which statement or statements apply to a bond which is selling at a premium?
SSSSS [86.1K]

Answer:

The best option is:

(a) I and II only

Step-by-step explanation:

Each kind of bond has a face value, usually known as par value. If a bond sells above the par value, it is a premium bond, if it sells below the par value, it is a discount bond. Hence first statement is true.

If a bond has a selling rate of 100, it means it is selling at its par value. For example if a bond has a par value of $100, then a selling rate of 100 means it sells at 100$, a selling rate of 90 means it sell at 90$, a selling rate of 120 means it sells at $120. For a premium bond, the selling rate is always above 100. Hence second statement is true.

Premium bonds are mostly sold by corporations, but alot of scheme of trading premium bonds have also been introduced by governments all around the world. We can say that the statement can be true for some specific country, but globally speaking, the statement is false.

Find the volume of the following square pyramid. geometry hw
Luda [366]

Given:

The square base pyramid with height 3 cm and base edge 2 cm.

To find:

The volume of the square pyramid.

Solution:

Volume of a square base pyramid is:

V=\dfrac{1}{3}Bh            ...(i)

Where, B is the base area and h is the height of the pyramid.

Base is a square with edge 2 cm, so the base area is:

B=a\times a

Where, a is the edge of the square base.

B=2\times 2

B=4

Putting B=4,h=3 in (i), we get

V=\dfrac{1}{3}(4)(3)

V=4

Therefore, the volume of the given pyramid is 4 cm³.
