Answer:
20 cm
Step-by-step explanation:
We can use ratios to solve
We know x = 7 since they are of equal length
x x+7
----- = -------
10 y
7 7+7
----- = -------
10 y
Using cross products
7y = 14*10
7y = 140
Divide by 7
7y/7 = 140/7
y = 20
Let’s say that the other one is described as X. So if one piece is twice as long as the other one, it’ll be 2x.
2x + X =111
3x = 111
3x divided by 3= 111 divided by 3
X= 37
So 2x = 2(37) = 74
X = 37
74
+ 37
————
111

Step-by-step explanation:
1The entire city of Athens is the:_______
a. population.
2) The 200 citizens from the researcher's data is the:______
a. sample
3) Which symbol would denote the value of 0.378 in this example?
Population proportion- average estimate of those residents in the entire city that are below the poverty line.
4) Which symbol would denote the value of 0.25 in this example?
Sample proportion - the average estimate of the 200 random sample residents that are below the poverty line.
A function can be represented on a table and on a graph.
The models of the linear relationship between f(x) and x are:
The given parameters are:
So, the function that models the linear relationship is:
Substitute known values
Evaluate all products
Rewrite as:
By comparing the above function to the list of options, we have the true options to be:

Given a trapezoid WXYZ. In a trapezoid one pair of opposite sides are parallel .Parallel lines have same slope.Slope of line parallel to x axis is 0.If the line starts at the bottom left and goes towards the top right it has negative slope.
All that is true for Trapezoid WXYZ are:
Line WZ has the same slope as line XY.
Line XW has a lesser slope than line YZ.
Line ZW has the same y-intercept as line WZ.
Line XY has a greater y-intercept
