The total length of all the lines drawn by the computer, in cm is 56 cm

<h3>How to determine the total length of all the lines drawn by the computer, in cm?</h3>

From the question we have the following parameters:

Start position: Top left corner
Movement: Anticlockwise around the edges of the square
Distance between lines: 1cm

From the figure, we have the following lines:

4 Vertical lines
3 Horizontal lines

The length of the vertical lines are:

Lengths = 10 cm, 10 cm, 9 cm

The length of the horizontal lines are:

Lengths = 10 cm, 9 cm and 8 cm

The total length is then calculated as:

Total length = Sum of vertical lines + Sum of horizontal lines

This gives

Total length = 10 cm + 10 cm + 9 cm + 10 cm + 9 cm + 8 cm

Evaluate the sum

Total length = 56 cm

Hence, the total length of all the lines drawn by the computer, in cm is 56 cm

HURRY PLEASE<br> e/2=3 <br> e=___ ?

Stolb23 [73]

Answer:

Step-by-step explanation:

To solve for e, it must be <em>alone</em> on one side of the equation

Your equation is:

e/2 = 3

To get rid of the divided by 2, you multiply both sides by 2 since multiplication is the opposite of divison.

So:

e/2 = 3

[Multiply both sides by 2]

e = 6

So, e = 6

I hope this helps! :)

A bank charges $3 each time you use an out-of-network ATM. At the beginning of the month, you have $1500 in your bank account. Y

Jlenok [28]

Answer:

$y=-\frac{63}{1} x+1500$

Step-by-step explanation:

Create a table:

1500 - 63(0) = 1500

1500 - 63(1) = 1437

1500 - 63(2) = 1374

1500 - 63(3) = 1311

Turn them into ordered pair:

(0, 1500)

(1, 1437)

(2, 1374)

(3, 1311)

When you multiply a pair of conjugates you get a real number

marusya05 [52]

Answer: The complex conjugate has a very special property. Consider what happens when we multiply a complex number by its complex conjugate. We find that the answer is a purely real number it has no imaginary part. This always happens when a complex number is multiplied by its conjugate the result is real number.

Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers

Step-by-step explanation: Every complex number has a complex conjugate. The complex conjugate of a + bi is a - bi. For example, the conjugate of 3 + 15i is 3 - 15i, and the conjugate of 5 - 6i is 5 + 6i.
