Answer:
By AA similarity
Step-by-step explanation:
We have been given that ABCD is a parallelogram
So, by the property of parallelogram AB ||CD and FD is cutting the line BC
Hence, FD is transverse line. In transverse line alternate angles are equal.
Therefore, ∠AFD=∠EDC (alternate interior angles)
And ∠FAD=∠ECD (opposite angles in parallelogram)
Therefore, by AA similarity △ADF∼△CDE

Answer:
The area of triangles are 16 cm^2 and 49 cm^2
Step-by-step explanation:
we know that
If two figures are similar, the ratio of its perimeters is equal to the scale factor and the ratio of its areas is equal to the scale factor squared
Let
z ----> the scale factor
x ----> the area of the smaller triangle in square centimeters
y ----> the area of the larger triangle in square centimeters
we know that
so
-----> equation A
----> equation B
solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x
therefore
The area of triangles are 16 cm^2 and 49 cm^2
Answer:
Average waste per day per person =1.51 pounds
Step-by-step explanation:
In 2010 do United States has a population of 309 million people. Also in the year 2010, do United States recycled 170,000 million pounds of waste.
We have to find the the average waste per person per day.
In a year there are 365 days.
In a day, the average amount of waste produced =
=
= 465.75 million pounds of waste
To find the average amount of waste produced per person per day, divide the average amount of waste produced per day by the total number of people in the country.
Average waste per day per person =
= 1.51 pounds
