The irrational number that represents the length of each side of the squares is 6.7082039324993 units.
In turn, since the upper side of the rectangle is twice the side of the square, the sides of the rectangle measure 6.7082039324993 units and 13.416407864998 units.
Since the length of a rectangle is twice the width, and the area of the rectangle is 90 square units, noting that the rectangle can be divided into two squares, to determine which irrational number represents the length of each side of the squares, and estimate the length and width of the rectangle, the following calculations should be performed:
- Rectangle = 90 square units
- Square = 45 square units each
- X ^ 2 = 45
- X = √45
- X = 6.7082039324993
- Therefore, the irrational number that represents the length of each side of the squares is 6.7082039324993 units.
- In turn, since the upper side of the rectangle is twice the side of the square, the sides of the rectangle measure 6.7082039324993 units and 13.416407864998 units (6.7082039324993 x 2).

The <em>correct answer</em> is:
4 points per multiple choice question
Explanation:
Let x be the amount each multiple choice question is worth. Since Gretchen answered 18 of them correctly, we would write this as 18x. Adding the 19 points for the essay question, we have 18x+19.
Since Ezia answered 15 multiple choice questions correctly, we would write this as 15x. Adding the 31 points for the essay question, we have 15x+31.
Since they had the same score, we set these equal to one another:
18x+19 = 15x+31
To solve this, first subtract 15x from each side:
18x+19-15x = 15x+31-15x
3x+19 = 31
Subtract 19 from each side:
3x+19-19 = 31-19
3x=12
Divide each side by 3:
3x/3 = 12/3
x = 4
Each question is worth 4 points.
So they’re supplementary angles which means that they add up to 180°… The equation would be: 5w+1+7w-7=180
5w+1+7w-7=180 (combine like terms)
12w-6=180
+6 +6
12w=186
w=15.5
Im not sure what they’re asking for but if they’re asking for w, your answer is 15.5, if they’re asking for the angle measure on the left, your answer is 78.5° & if they’re asking for the angle measure on the right, your answer is 101.5° :) hope this helps
The length of the rectangle equals 80 cm, and the width equals 32 cm.
Divide the length to the width, we get the ratio between them :
80 : 32
Now, we simplify by dividing them both by the same number, in this case it's 16
=> 80 : 32 = (80 : 16) : (32 : 16) = 5:2
So, the ratio between the length and the width is 5:2
