Step-by-step explanation:

By rotating a figure,

The length of its sides remain the same.

Therefore line AB = line A'B'.

=> 5x - 14 = 4x + 4

=> x = 18

Hence, line AB = 5(18) - 14 = 76.

Answer:

The length of AB = 76 units.

Step-by-step explanation:

We know that Rotations, just like reflections, and translations, are termed isometric.

In other words, these transformations do not alter the size of the figure.

If the size and shape of the figure are not altered, then the figures are termed as congruent.

Given

AB = 5x-14

A'B' = 4x+14

As A'B'C'D' is obtained by rotating ABCD,

AB = A'B'

substituting AB = 5x-14 and A'B' = 4x+14

5x-14 = 4x+14

5x - 4x = 14+14

x = 18

Thus,

AB = 5x-14

substitute x = 18

AB = 5(18)-14

AB = 90 - 14

AB = 76

Therefore, the length of AB = 76 units.

You are wearing a pair of cargo pants with six pockets. You've put $10 in one of the pockets, but you cannot remember which one.

Over [174]

There are 6 pockets all together. You checked two of them and it wasn't
there. So you can forget about those 2, and now there are 4 pockets left.

The total number of ways for your next try is 4.
The number that will be successful is 1.

The probability of success on the next one is 1/4 = 25% .

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

Another method of solution, somewhat more complex:

Total number of pockets = 6.
Amount of money missing = $10
First partial sum, i.e. sum of numbers
in the first part of the problem = 6 + 10 = 16.

Total number of pockets = 6
Current value of cargo pants on a fashion scale from 1 to 10 = -2.
Second partial sum = 6 - 2 = 4.

Probability = (second partial sum) / (first partial sum) = 4/16 = 25% .

How To Round 17 5/8 To The Nearest Whole Number

Verdich [7]

Answer:
18

Explanation:
To round a number to the nearest whole number, we would check the fraction part:
If the fraction is less than 0.5, then we would simply ignore the fraction
If the fraction is equal to or more than 0.5, then we would add 1 to the whole number and eliminate the fraction.

In the given , we have:
 $17 \frac{5}{8}$ .

The fraction part is $\frac{5}{8}$ which is greater than 0.5
This means that we would add one to the whole number (round it up) and eliminate the fraction.
Therefore, the answer would be 18.

Hope this helps :)
