3/10+6/100+2/1000 that is my answer your welcome;)
Yes, the two rectangles are similar, because rectangle 2 is a dilation of rectangle 1.
<h3>
Are the two rectangles similar?</h3>
We know that rectangle 1 has dimensions L and W.
And rectangle 2 is made by multiplying the dimensions of rectangle 1 by a factor k > 0.
Then, rectangle 2 is just a dilation of rectangle 1, this means that in fact, the two rectangles are similar by definition.
Then:
Dimensions of rectangle 1:
- Length = L
- Width = W.
- Perimeter = 2*(W + L)
- Area = W*L
For rectangle 2:
- Length = k*L
- Width = k*W
- Perimeter = 2*(k*L + k*W) = k*(2*(L + W))
- Area = (k*L)*(k*W) = k²(L*W)
Above we can see that the perimeter of rectangle 2 is k times the perimeter of rectangle 1, and the area of rectangle 2 is k squared times the area of the rectangle 1.

Answer:35
first u put the numbers in order.....very important to do this
3,5,23 ,27 35, 37, 45, 48, 49, ,
the median is the middle number. So the median is 35
Triangle on the left: 30 60 90 right triangle
so ratio of short leg: long leg: hypo = x : x√3 : 2x
given hypo = 4√3
so
short leg = 4√3 / 2 = 2√3
long leg = 2√3 * √3 = 6
a = 6 and c = 2√3
triangle on the right is 45 45 90 right triangle
so ratio of leg: leg: hypo = x : x : x√2
from above you know a = 6 so d = a = 6
b = 6√2
Answer
a = 6, b = 6√2, c =2√3 and d = 6
