Dilation always preserves angle measures, the given statement best explains why the dilation of a triangle produces a similar triangle
<u>Step-by-step explanation:</u>
The dilation (similarity transformations) varies the size of the figure. This requires a midpoint and a scale factor k. The k value finds whether it is an increase or decrease.
- If | k |> 1, the dilation is an extension.
- If | k | <1 it is reduction.
The absolute value of k determines the size of the new image relative to the size of the original image. If the k is positive, the new and original image is on the same side of the center.
If k is negative, they are on both sides of the center. Its own image is always at the center of development. This support angle size, point equality, and collinearity. Does not maintain distance. In simple, dilation always give similar figures.
For 11a its 2:10 because how you would come up with it is by placing pablos free minutes first and then putting pablos paid minutes and 11b is8:25 because once again you would place sams free minutes first and then his paid minutes
x=6
if you multiply 4 by whats inside the parenthesis you get 5x+16x+44=170
next combine like terms and get 21x+44=170
next subtract 44 from itself and 170 to get 21×=126
finally divide 21 from both sides and you get x=6
hope this helps!
Answer:
The answer is 1.
Step-by-step explanation:
Answer:
hay 10 billetes de 2000
hay 4 billetes de 5000
Step-by-step explanation:
Planteamos las siguientes ecuaciones...:
x= billetes de 2000
y= billetes de 5000
ecuaciones :
1) x+y = 14
2) 2000x + 5000y =40000
despejamos primera ecuacion y remplazamos en segunda :
1) x= 14-y
2) 2000(14-y) + 5000y = 40000
28000- 2000y+5000y = 40000
3000y= 40000 - 28000
y= 4
reemplazamos este valor en primera ecuacion:
x+y = 14
x+ 4= 14
x= 10
ahora reemplazamo valor de X y valor de Y
2000(10) + 5000(4) =40000
40000 =40000
hay 10 billetes de 2000
hay 4 billetes de 5000
Espero que esto te ayude
