A mine worker is in a tunnel 25 feet below the ground. He descends another 13 feet. What is his final position? i already know t

Marina86 [1]

Answer: -25 - 13

This simplifies to -38

So the worker's final position is 38 feet below the ground.

A diagram is shown below.

==========================================================

Explanation:

Draw a vertical number line. Plot 0 on it to indicate the ground level, or surface level. Then plot -25 on it, which is below 0. This is 25 feet below the ground.

To move 13 further feet downward, we will subtract 13 from -25. Subtracting a positive means we move downward.

For example, start at the 30th of a building. This is marked as +30 or just 30 on the vertical number line. Subtract off 13 to go down 13 floors and we have 30-13 = 17. So after going down 13 floors, we're at the 17th floor now.

Going back to the problem at hand, we start at -25 and subtract off 13 to get the final answer -25 - 13

The answer is not -25 - -13 and it is not -25 - (-13). This is because the two negatives cancel to be a positive. So -25 - (-13) becomes -25+13. Here we're starting at -25 but then going up 13 feet. Instead we want to go down 13 feet.

------------------------------------

After we determine the expression is -25 - 13 we will effectively add the positive versions of those numbers like so

25+13 = 38

But the final answer is negative because we're starting underground and moving further underground.

We can write it like this

-25 - 13 = -(25+13) = -(38) = -38

Therefore, if the worker starts off 25 feet underground, and moves 13 feet downward, then the worker ends up 38 feet underground. Again, use the vertical number line to help see this.

Which transformations must be applied to object A to place it in the position of object B?

NeX [460]

In order for object A to be placed in the position of object B, there needs to be a rotation and translation.

<h3>How would object A get to object B?</h3>

The first step would be to rotate object A to the left to give it the same orientation as object B.

Then, translate object A to the coordinates of object B. This would lead to object A fitting into object B.

How to i devide decimalls?

sashaice [31]

Any decimal whole number can be written as a whole number multiplied by a power of 10. For example,

3 = 3 × 10⁰

100 = 1 × 10²

15,000 = 15 × 10³

The power of 10 that you need depends on how many trailing zeroes you want to remove.

A number with a decimal point can be written the same way, but the power of 10 is negative:

0.3 = 3 × 10⁻¹

0.01 = 1 × 10⁻²

12.345 = 12,345 × 10⁻³

You can employ this sort of manipulation when you're dividing two real numbers. You end up with the quotient of two whole number, and you just need to keep track of power of 10 you end up with.

For example, consider the fraction

1.23 / 0.456

Rewrite this as

(123 × 10⁻²) / (456 × 10⁻³) = 123/456 × 10¹

where we end up with 10¹ because 10⁻²/10⁻³ = 10⁻²⁻⁽⁻³⁾ = 10³⁻² = 10¹.

Now just compute the quotient 123/456 and multiply that result by 10, which amounts to shifting the decimal point one position to the right. You would end up with

123/456 ≈ 0.269737

so that

1.23 / 0.456 ≈ 2.69737
