For this case, the first thing you should do is know that dilation is a transformation that is used<em> to lengthen or shorten a geometric figure.
</em>
Geometric figures can be triangles, squares, circles, or any polygon.
There is a point on the plane, at which the dilation begins to be drawn.
This point on the plane is what we know as the center of dilation
.
Answer:
B. the center of dilation
The regular price is 5 for $2.95. One can is $2.95/5 = $0.59. Three cans are $1.77. With the $1 rebate, the final price would be $0.77 for 3 cans, $0.25 per can.
We have two right triangles and three different rectangles.
The formula of an area of a right triangle:
l₁, l₂ - legs
We have l₁ = 20cm and l₂ = 21cm. Substitute:
The formula of an area of a rectangle:
l - length
w - width
We have:
rectangle #1: l = 22cm, w = 29cm
rectangle #2: l = 22cm, w = 21cm
rectangle #3: l = 22cm, w = 20cm
The total Surface Area of the triangular prism:
