Square ABCD is located on a coordinate plane. The coordinates for three of the vertices are listed below. ~A(2,7) ~C(8,1) ~D(2,1
Vladimir79 [104]

Answer:

B' (16, 14)

Step-by-step explanation:

<em>Whenever we have a dilation with a scale factor b, we get the new point as:</em>

<em>Let original point be (x,y), then the dilation would make it (bx, by).</em>

<em />

There is a diagonal that goes through AC and another through BD. The midpoint of both the diagonal is same. Midpoint formula is:

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

<u>Midpoint of AC:</u>

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\=(\frac{2+8}{2},\frac{7+1}{2})\\=(5,4)

Now let vertex B have coordinates (x,y). <u>Midpoint of BD:</u>

(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\=(\frac{x+2}{2},\frac{y+1}{2})

<em>Equate this to the midpoint of AC:</em>

<em>(x+2)/2=5</em>

<em>x+2 = 10</em>

<em>x = 8</em>

<em />

<em>and</em>

(y+1)/2=4

y+1=8

y = 7

Thus, B(8,7)

<em>recalling dilation of scale factor 2 rule we said at the beginning, B' would be twice of each coordinate. Hence B' = (16,14)</em>

45% of a number is 180. Find the number
KonstantinChe [14]

Answer:

81

Step-by-step explanation:

The term "of" can be translated to multiplication in problems like this.

So it's essentially saying multiply 45% to 180 and give me the result.

45% can be written as 45/100 in fractions (45 percent, where cent means 100 and per means division). 45/100 can be written as 0.45 in decimal form.

Now the problem reads 0.45 X 180. Using a calculator, we can solve this and the result comes out to be 81

I need help on number 29 please explain this too.
Sedaia [141]
The correct answer is C.

A parallelogram has 2 pairs of opposite, equal, and parallel sides and a rectangle has 2 pairs of opposite, equal, and parallel sides BUT it also forms right angles between adjacent sides. In other words a rectangle is everything that a parallelogram is but with a little more, so the parallelogram would be inside of the rectangle. (if that makes any sense?)
