Answer:
C. -1 9/10, -1/2, 0.4, 3/5
Step-by-step explanation:
Using a number line, we can see that negative numbers are to the left of '0' and positive numbers are to the right of '0'. To compare numbers for increasing order, we would start with the lowest number to the farthest left on the number line to the greatest number to the farthest right. Placing the following numbers on the number line, the furthest to the left is -1 9/10, then -1/2, followed by 0.4 and then the greatest, 3/5. You can also compare by converting them all into decimals:
-1 9/10 = -1.9
-1/2 = -0.5
0.4 = 0.4
3/5 = 0.6
Well first you find the area of your basic rectangle with equation:
area (a) = length (L) * width (w)
So we got:
a = L * w
Now we find the area of a new rectangle with quadruple side lengths than our (a) rectangle and im going to call this area A:
A = 4L * 4w or A = 4 (L * w)
we want to see how the ratio of A to a or A/a so we can set both equations equal to 1 by dividing the areas to both sides of their respective equations:
1 = (L * w) / a and
1= 4(L * w) / A
since they both equal 1 then the equations have to equal each other:
(L * w) / a = [4 (L * w) / A
cross multiply
A *(L * w) = a *[4 (L * w)]
divide both sides by (L * w)
A = 4a
as you can see by quadrupling the sides by 4, this small rectangles area would also increase by a factor of four
Answer:
15 in.
Step-by-step explanation:
The area of the left-most square is 81 in.^2. Area = L*W (Length times width), and since we know squares are always equal on each side, we can do 9*9=81. That means the left side of the triangle is 9.
Then, we move to the bottom-most square. The perimeter is 48 in. As said before, we know all sides of a square must be equal. We will divide 48 by 4, as that's how many sides a square has (mind-blowing!), and we get 12. That means, using the Pythagorean Theorem, (9^2) + (12^12) = C^2. We can simplify this to 81 + 144 = C^2, or 225 = C^2 if you add those two numbers together. We can take the square root of both sides to get C = 15!
