No; percent is not greater than decimal. Percent is LESS than the number is decimal.
In fact, take any number---decimal or other wise, and divide that number by "100" to convert is to its form in "percent".
<span>_______________________________________... </span>
<span>"Percent" mean "per hundred"--or "parts per hundred". </span>
<span>_______________________________________... </span>
<span>0.14 is less than "140%". </span>
<span>140% = 140 parts per hundred = 140/100 = 1.40 ---> 1.40 > 0.14 </span>
<span>_______________________________________... </span>
<span>Note: 0.14 = 14/100 = (0.14*100) %= 14 parts per hundred = 14% </span>
<span>140% > 14%</span>
The answer is arctan(16/17). Use a calculator to evaluate it.
slope-point form:
we need the slope (m) and a point.
y-y₀=m(x-x₀)
Given two point A(x₁,y₂) and B(x₂,y₂), the slope of the line is :
m=(y₂-y₁) /(x₂-x₁)
Example 3:
we can take two points:
A(12,2)
B(13,7)
m=(7-2) / (13-12)=5/1=5
therefore:
y-2=5(x-12)
y-2=5x-60
y=5x-60+2
y=5x-58
answer: y=5x-58
Example 4:
we can take two points.
A(0,0)
B(3,1)
m=(1-0)/(3-0)=1/3
Therefore:
y-0=1/3(x-0)
y=x/3
answer: y=x/3
1.5x + 0.2y = 2.68....multiply by 0.3
1.6x + 0.3y = 2.98...multiply by - 0.2
------------------------
0.45x + 0.06y = 0.804 (result of multiplying by 0.3)
- 0.32x - 0.06y = - 0.596 (result of multiplying by - 0.2)
----------------------add
0.13x = 0.208
x = 0.208/0.13
x = 1.6
1.5x + 0.2y = 2.68
1.5(1.6) + 0.2y = 2.68
2.4 + 0.2y = 2.68
0.2y = 2.68 - 2.4
0.2y = 0.28
y = 0.28/0.2
y = 1.4
solution (they intersect at) (1.6,1.4)
