Answer:

The surface area of the cube is 648.96 sq in.

Step-by-step explanation:

This problem is made a lot easier by the fact that it's a cube.

So we first calculate the area of one of the faces. The length of the side of the side is 10.4 inches, and <em>10.4 * 10.4 = 100.16.</em>

There are six faces, so we multiply the area of 1 face by 6. <em>100.16 * 6 = 648.96. </em>

Therefore, the surface area of the cube is 648.96 sq inches.

<em>Hope This Helps!</em>

Solve the following system. Please show me how you did it.
Andrej [43]

Answer:

x = 3, y = 4 and z = -5.

Step-by-step explanation:

Use the elimination method:

-3x + 2y + z = -6...........(1)

x + 3y + 2z = 5..............(2)

4x + 4y + 3z = 13..........(3)

Multiply the first equation by -2:

6x - 4y - 2z = 12   Add this to equation (2):

7x  - y  = 17...........(4)

Now Multiply equation (2) by 3 and equation (3) by -2

3x + 9y + 6z = 15 ............(5)

-8x - 8y - 6z = -26............(6)   Adding (5) + (6):

-5x + y = -11..........(7)

Now Add (7) and (4):

2x = 6

x = 3.

Now  substitute for x in (4):

7(3) - y = 17

-y = 17 - 21 = -4

y = 4.

Finally substitute for x and y in equation (3) to find z:

4(3) + 4(4)  +3z = 13

3z = 13 - 12 - 16 = -15

z = -5.

A stockholder owns 381.881 shares. By the end of the year, he had increased his number of shares by 14.814. What’s the new total
beks73 [17]

Answer:

438.453 shares

Step-by-step explanation:

<em>From my understanding, the question says that the shares were increased by 14.814%.</em>

<em>Therefore, we have to calculate the increase</em>

<u>Step 1: Calculate the increase</u>

Previous shares : 381.881

Increase : 14.814%

Increase = 381.881 x 14.814% = 56.572

<u>Step 2: Calculate the new total shares</u>

New shares = 381.881 + (381.881 x 14.814%)

New shares = 381.881 + 56.572

News shares = 438.453

Therefore, the new total shares owned by the stockholder are 438.453 shares.
