Answer:

A. Each shape has 12 edges

Step-by-step explanation:

A is the only one that is true.

The shapes have 6 faces, not 7 or 8.

The edges are the places were two planes intersect, and there are 12, not 6.

Answer:

x=9

Step-by-step explanation:

step one pull out the factors

 3x - 27  =   3 • (x - 9)

and step two: Equations which are never true

2.1      Solve :    3   =  0

This equation has no solution.

A a non-zero constant never equals zero.

so x-9=0 and add both sides to 9 and to equal 9

Employees at a clothing store recieve 20% discounts on what they purchase at that store. How much will an employer save on a $45
mamaluj [8]
Easiest way to work it out is to divide by ten, that gives 10% of your original number. Multiply that by two to get 20% and minus that from the original number to get the discount.
450/10 = 45 which is 10% of 450.
20% of 450= 10% x 2 or 45 x 2
therefor 20% of 450 is 90.
450-90 = the discount the shoppers recieve.

Please help me with this pleaseee

Answer:

x = 88.2

Step-by-step explanation:

The angle at the top of the triangle = 90° - 10° = 80°

and the left side of the triangle is x ( opposite sides of a rectangle )

Using the tangent ratio in the right triangle

tan80° = \frac{opposite}{adjacent} = \frac{500}{x}

Multiply both sides by x

x × tan80° = 500 ( divide both sides by tan80° )

x = \frac{500}{tan80} ≈ 88.2
