Answer:

The answer is "496"

Step-by-step explanation:

It begins at 0000 or finishes at 1111:

$= 2^8 + 2^8 - 2^4\\\\= 256 +256 -16\\\\= 512 - 16 \\\\= 496$

Quadrilateral A has side lengths 6, 9, 9, and 12. Quadrilateral B is a scaled copy of Quadrilateral A, with its shortest side of

Varvara68 [4.7K]

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

a) The scale factor from Quadrilateral A to Quadrilateral B = smallest side length of side B / smallest side length of side A = 2 / 6 = 1/3

Scale factor = 1/4= 1 / 3

The side length of 6 in A corresponds to a side length of 2 in B

Side length of B that corresponds with side length of 9 in A = scale factor * 9 = 1/3 * 9 = 3

The side length of 9 in A corresponds to a side length of 3 in B

Side length of B that corresponds with side length of 12 in A = scale factor * 9 = 1/3 * 12 = 4

The side length of 12 in A corresponds to a side length of 4 in B.

c) perimeter of Quadrilateral B = sum of side lengths of quadrilateral B = 2 + 3 + 3 + 4 = 12 units

stich3 [128]

Answer:

x= -9

Step-by-step explanation:

7(x+2) = -49

7(x+2)/7 = -49/7

x+2 = -7

x+2-2 = -7-2

x = -9

An Airbnb home has installed a combination lock with push buttons labeled A though F (six buttons) and uses four of these button

SpyIntel [72]

The number of different codes does this lock provides is 360.

Given that,

There is the combination lock having push buttons from A to F (6 buttons)
Out of this, four should be in any order.
Also, the push button should not be used more than once.

Based on the above information, here we use permutation which is as follows:

$= ^6P_4\\\\= \frac{6!}{(6-4)!} \\\\$

= 360

Therefore we can conclude that the number of different codes does this lock provides is 360.
