<span>In order to solve this you would need to take the difference in population and then divide by the difference of the number of years that have passed. So first we figure that there is a 30 million difference in population over the course of 10 years. So you would take 30 and divide by 10. Your problem would then appear as this 30/10=3 ... ( I removed all unnecessary zeros from the equation to simplify it). The answer is an annual rate of 3 million people per year (after adding back all necessary zeros to get back to the proper population number in the millions).</span>
(The answer is 12.082.) Juan used 12.082 meters of rope.
The area of a triangle in terms of height and base is A = 1/2*base*height
Suppose base = 6 cm and height = 12 cm. Then, A = 1/2*6*12 = 36 cm2.
If the base and height are scales by a factor of 5, b= 30 cm and h = 60 cm. Then, A = 1/2*30*60 = 900 cm2.
Thus the area of the resulting triangle is scaled by a factor of 25, which is 900 cm2.
Answer:
length = 10 ft, width = 9 ft
Step-by-step explanation:
The opposite sides are congruent
The perimeter (P) = 38 and is the sum of the 4 sides, then
15 - 2x + 15 - 2x + x + 7 + x + 7 = 38 , that is
- 2x + 44 = 38 ( subtract 44 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3
Then
length = x + 7 = 3 + 7 = 10 ft
width = 15 - 2x = 15 - 2(3) = 15 - 6 = 9 ft
Answer:
the correct answer is option c. y= 192/x
