A triangle has the vertices A(-7, 8), B(1, -7), and C(7,6). After a dilation, the vertices of the image are A(-28, 32).

steposvetlana [31]

Answer: the answer is A.4

Step-by-step explanation:

Dilation in this context is the transformation is an object into a larger one.

ABC is transformed to A'B'C'

To get the scale factor, we divide the coordinates of A'B'C' by ABC

i.e

A'/A = -28/-7, 32/8 = 4

B'/B = 4/1, -28/-7 = 4

C'/C = 28/7, 24/6 = 4

An 8 by 19 ft wall has three 4 by 5ft windows. The area of three windows is what percent of the area of the entire wall

sergij07 [2.7K]

Area of the wall = 8 x 19 = 152 ft square
Area of the window = 4 x 5 = 20 ft square
Area of 3 windows = 20 x 3 = 60 ft square
The percent area of 3 windows from area of the wall = 60/152 or approximately .395 or 39.5%

1.6/n = 1.2/20<br> What's the correct answer?

natita [175]

Answer:

n = 26 2/3

Step-by-step explanation:

Step 1: Cross-multiply.

$(1.2) * (n) + 1.6*20$
$1.2n =32$

Step 2: Divide both sides by 1.2

$1.2n/1.2 = 32/1.2$
$n = 26\frac{2}{3}$

Therefore, the answer is n = 26 2/3.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
