Answer:

The net, when folded into a cube, has a total surface area of 2,400 sq.units

Step-by-step explanation:

The length of all sides of a cube are the same.

Now, the surface area of a cube is the sum of the area of all of its faces.

Since the length of all sides are the same and we are told that the length of a side is 20 units, thus, the area of one face is;

A = 20 x 20 = 400 sq.units

So, one the area of a face is 400 sq.units.

Now, since all the faces are the same measurement, thus each face will have an area of 400 sq.units. Cubes have 6 faces, thus the total surface Area is;

Total = 400 x 6 = 2400 sq.units

The net, when folded into a cube, has a total surface area of 2,400 sq.units

What is the simple interest of a note that has a face value of $12,000, a rate of 8%, and a term of 1 year?
Tju [1.3M]

Solution:

Given:

\begin{gathered} P=\text{ \$}12,000 \\ R=8\text{ \%} \\ T=1year \end{gathered}

Using the simple interest formula,

\begin{gathered} I=\frac{PTR}{100} \\ I=\frac{12000\times1\times8}{100} \\ I=\text{ \$}960 \end{gathered}

Therefore, the simple interest is $960.

Steve and Elizabeth decide to become partners in a children’s cooking school. They need $80,000 for the franchise. They invest i
PilotLPTM [1.2K]

Answer:

The share of Steve  is $34,285 .71

The share of Elizabeth  is  $45,714.28

Step-by-step explanation:

The total investment of Steve and Elizabeth in cooking school = $80, 000

The ratio of investment of  Steve and Elizabeth  = 3: 4

Let us assume the common factor in the ratio is m.

So, the ratio of  Steve = 3 m

and the ratio of  Steve = 4 m

So, according to the question:

⇒ 3 m + 4 m   =  80,000

or, 7 m = 80,000

⇒ m = 80,000 / 7 = 11,428.57

or, m = 11,428.57

⇒ The share of Steve = 3 m = 3 x (11,428.57)  = 34,285 .71

⇒ The share of Elizabeth = 4 m = 4 x (11,428.57)  = 45,714.28
