I’ll say about 45 because one year hurt but my bones hurt one time and they did not like it
Answer:
If two figures are similar, then the correspondent sides are related by a constant factor.
For example, if the base of one side of one of the figures has a length L, then the correspondent side of the other figure has a length k*L where k is the scale factor.
Let's start with the two left triangles.
In the smaller one the base is 5, and the base of the other triangle is 15.
Then we will have:
15 = k*5
15/5 = k = 3
The scale factor is 3.
Then we will have that:
a = scale factor times the correspondent side in the smaller triangle:
a = k*3 = 3*3 = 9
a = 9
For the other two triangles, the base of the smaller triangle is 12, while the base of the larger triangle is 20.
Then we will have the relation:
12*k = 20
k = (20/12) = 10/6 = 5/3
The scale factor is 5/3
This means that the unknown side b is given by:
b*(5/3) = 15
b = (3/5)*15 = 3*3 = 9
b = 9.
The average rate of change in the median household income over this time period is $745.5
<h3>What is the average rate of change in the median household income over this time period?</h3>
The given parameters are:
2000, the median household income was $41,990.
2010, it was $49,445.
The average rate of change in the median household income over this time period is calculated as:
Average rate of change = (Difference in Income)/(Difference in years)
So, we have:
Average rate of change = (41990 - 49445)/(2000-2010)
Evaluate
Average rate of change = 745.5
Hence, the average rate of change in the median household income over this time period is $745.5

Answer:
T= (2, 0)
Step-by-step explanation:
(2,0) + (4, 4) = (6, 4)
(6, 4) + (4, 4) = (10, 8)
