Answer:

Step-by-step explanation:

A reflection is a transformation representing a flip of a shape/figure

A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point.

A dilation (similarity transformation) is a transformation that changes the size of a figure. It requires a center point and a scale factor. The value of k determines whether the dilation is an enlargement or a reduction.

Terri Clifford bought a Sunday dress for $36. The sales tax was 6%. Find the total cost of the dress.

Kipish [7]

Total cost is $38.16

Multiply 36 by 0.06 (2.16)
Add 2.16 to 36 (38.16)

Answer:

The fourth opition!

Step-by-step explanation:

180-2(72)=x. The reason being it says TWO angels of 72 and if you times that by two and subtract by 180 youll get the missing angle!!

2. Rich wrote a novel that sells for n dollars each. He received a bonus of $50,000 to sign the

Yuki888 [10]

The equation which represent total amount of income he earns from selling book is, $A=50000+\frac{109}{100}bn$

Since, Selling price of one novel is n dollars

So, selling price of b books is, $n*b=nb$

Since, he receives 9% commission on each book sale.

So, total commission he receives on selling of b books is,

$nb*\frac{9}{100}=\frac{9}{100}nb$

And also he received a bonus of $50,000 to sign the contract to write the book,

So, total amount of income he earns is represented by A,

$A=50000+bn+\frac{9}{100}bn\\\\A=50000+\frac{109}{100}bn$

Answer:

1296mm^2

Step-by-step explanation:

Surface Area of the Rectangular Prism to the left on top of the box:

Area of square = lw, 9mm * 9mm = 81mm, then multiply by 2 because 2 of the squares are a part of the surface, giving 162mm^2

Area of a rectangle =lw, 9mm * 9mm = 81mm, then multiply by 2 again, because 2 rectangles are a part of the surface, giving 162mm^2

So, the total surface area of the rectangular prism to the left on top, is 324mm^2

Surface Area of the Triangular Prism:

Area of a triangle: 1/2bh, and our base length would be 12, because we have to subtract 9 from 21 since the base length of the triangle isn't stated. Anyways, A = 1/2bh, so A = 1/2(12)(9) = 54mm^2, but multiply by two, so we get 108mm^2.

Area of the rectangle: lw, so 15mm * 9mm = 135mm^2

So, the total surface area of the triangular prism is 243mm^2

Surface Area of the Rectangular Prism at the bottom:

Area of the long rectangles in front = lw, 21mm * 9mm = 189mm^2, multiply by 2, 378mm^2

Area of the rectangles to the side = lw, 9mm * 9mm = 81mm^2, multiply by 2, 162mm^2

Area of the rectangle at the very bottom = lw, 21mm * 9mm = 189mm^2

So, the total surface area of the rectangular prism at the bottom is 729mm^2

Add all the total surface areas of each shape to get the total surface area of the figure:

324mm^2 + 243mm^2 + 729mm^2 = 1296mm^2

The surface area of the figure above is 1296mm^2
