Which graph shows the result of dilating this figure by a factor of 4 about the origin? On a coordinate plane, rectangle A B C D
Andrei [34K]

Answer:

Second option: On a coordinate plane, rectangle A'B'C'D' prime has points (-4,4),(12,4),(12,-4),(-4,-4)

(See the graph attached)

Step-by-step explanation:

For this exercise it is importnat to know that a Dilation is defined as a transformation in which the Image (The figure obtained after the transformation) has the same shape as the Pre-Image (which is the original figure before the transformation), but they have different sizes.

In this case, you know that the vertices of the rectangle ABCD ( The Pre-Image)  are the following:

A(-1,1)\\\\B(3,1)\\\\C(3,-1)\\\\D(-1,-1)

Therefore, to find the vertices of the rectangle A'B'C'D' (The Image)  that results of dilating the rectangle ABCD by a factor of 4 about the origin, you need to multiply the coordinates of each original vertex by 4. Then, you get:

A'=((-1)(4),(1)(4))=(-4,4)\\\\B'=((3)(4),(1)(4))=(12,4)\\\\C'=((3)(4),(-1)(4))=(12,-4)\\\\D'=((-1)(4),(-1)(4))=(-4,-4)

Finally, knowing those points, you can identify that the graph that shows the result of that Dilation, is the one attached.

Given: LMNP is a square A, B midpoints of LM and PN Q ∈ AB m∠LPQ = 45° Find: m∠PQN
lisov135 [29]
Since A and B are the midpoints of ML and NP, we can say that AB is parallel to MN and LP. In order to find ∠PQN, we can work with the triangles PQB and NQB. According to SAS (Side-Angle-Side) principle, these triangles are congruent. BQ is a common side for these triangles and NB=BP and the angle between those sides is 90°, i.e, ∠NBQ=∠PBQ=90°. After finding that these triangles are equal, we can say that ∠BNQ is 45°. From here, we easily find <span>∠PQN. It is 180 - (</span>∠QNP + ∠NPQ) = 180 - 90 = 90°

C. a different class is made up of 60​% women and has 24 women in it. what is the total number of students in the​ class?
Jobisdone [24]
The answer is:  " 40 students " .
______________________________________________________
Explanation:
______________________________________________________

60% of x = 24 .  Find "x" .  in which "x" = total number of students; 

60 % = 60/100 = 6/10 = 3/5.

(3/5) x = 24 ;

Multiply EACH SIDE of the equation by "5" ; to get rid of the fraction:

5* (3/5)x = 24*5 ; 

3x = 120 ;

Divide each side of the equation by "3" ; 
   to isolate "x" on one side of the equation; and to solve for "x" ; 

3x / 3 = 120 / 3 ; 

 x = 40 .
______________________________________________________
The answer is:  " 40 students " .

During an evening out, Dean paid a cab driver $20. He then spent $25 on dinner and half of his remaining money on a painting. He
DedPeter [7]

The way I see it is like this:


He ended with $42.15 -- the last thing that he did before that was buy the umbrella

$42.15 + $23.75 (umbrella) = $65.90


The next thing backwards in order is that he spent "half of his remaining money on a painting", so what he has left is one half what he had before he bought the painting.

$65.90 + $65.90 (cost of the painting) = $131.80


Before that, he spent $25 on dinner and $20 on a cab. So we add those all up:

$131.80 + $25 (dinner) + $20 (cab) = $176.80 (how much money he had at the start of the weekend)


To write it as a single equation:


$42.15 = -$23.75 + (-$25.00 + -$20.00)/2
