according to the 2000 U.S. Census, 138,053,563 Americans are male, and 143,368,343 Americans are female. About what percent of f

Male = 138,053,563

Female = 143,368,343

Total

The total equals 281 421 906

Percents

Male = (138,053,563 / 281 421 906) * 100 = 49.1%

Female = ( 143,368,343/ 281 421 906) * 100 = 50.94%

Rounded

Male = 49

Female = 51

Comment.

To find this %s you could just use the first 3 digits of everything.

Total = 138 + 143 = 281

% male = (138/281) = 49.1

% female = (143/281) * 100 = 50.88

These give you the same answers when rounding.

How many solutions does the system of equation have?

serious [3.7K]

We can determine the number of solutions from the slope intercept form of the equations.

Slope intercept form of equation 1 is:

$y=- \frac{1}{4}x+3/4$

Slope intercept form of second equation is:

$y=- \frac{1}{4}x+ \frac{9}{12} \\ \\ 
y= - \frac{1}{4}x+ \frac{3}{4}$

The slope and the y-intercept of both equations are the same. This means, the two lines are lying over each other and hence they infinite number of solutions.

So, the correct answer is option C
