Two squares is sometimes similar.
A square can be any size, as long as all four of it's sides are equal.
A square would be a rectangle if two of the sides were different than the rest.
A square would be a trapezoid if only one of it's sides were different.
For a square to be always similar, the ratio of it's sides must be equal to the ratio of the second square.
For example:
All of a square's sides are 5 across.
In order for another square to be ALWAYS similar, it's sides must be a multiple of (The length of the original square's sides) 5 (10,15,20,25,30...)
This is called a ratio. (5/10 = 1/2, 5/15 = 1/3, 5/20 = 1/4 etc...)
3.4 cubic feet x 4.8 cubic feet= 16.32 is the answer
Answer:
180ft^2
Step-by-step explanation:
w = .8l = 15 x .8 = 12ft
A = l x w = 15 x 12 = 180ft^2
Answer:
-8
Step-by-step explanation:
If we let x and y represent the first and second numbers, respectively, we can write the problem statement as the equations ...
We can multiply the first equation by -9 and add 4 times the second equation to get an equation in y alone:
-9(4x +5y) +4(9x +2y) = -9(-28) +4(11)
-37y = 296 . . . . . simplify
296/-37 = y = -8 . . . . . divide by the coefficient of y
The second number is -8.
If your decimal is 1/2 or more u round up if it is less than half u round down
