Answer:
16% is the percent of increase to the nearest whole-number percent.
Step-by-step explanation:
As the cost of a pound of nails increased from $2.17 to $2.52.
so dividing the 0.35 by 2.17 would give us the percetange of increase
- 0.35/2.17 = 0.16 which is 16%.
Therefore, 16% is the percent of increase to the nearest whole-number percent.
Answer:
1222 billion dollars.
Step-by-step explanation:
To find the total increase from 1960 to 2010, we need to find the growth of each decade and sum them all:
In the period 1960-1970, we have x = 1, and the growth is:
In the period 1970-1980, we have x = 2, and the growth is:
The growth in the following 3 periods are:
So the total growth in the period 1960 - 2010 is:
Rounding to the nearest billion dollars, we have a total of 1222 billion dollars.
Answer: x = 0
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
General equation for a circle
(x - a)² + (y - b)² = r²
with (a,b) represents the center, (x,y) represents one of the points lie on the circle, and r represents the radius
Determine r² by substituting the points into the general equation
(x - a)² + (y - b)² = r²
(5 - (-1))² + (-4 - 2)² = r²
(5 + 1)² + (-6)² = r²
6² + 36 = r²
36 + 36 = r²
72 = r²
Determine the equation of the circle
(x - a)² + (y - b)² = r²
(x - (-1))² + (y - 2)² = 72
(x + 1)² + (y - 2)² = 72 (This is the equation of the circle)
