What would be the value of expressing something like the national debt in scientific notation? What information would be lost in

Vikki [24]

As of January 8, 2015, the U.S. is $18.1 trillion in debt. (Source: National Priorities Project)

1 Trillion

= 1 Thousand Billion

= 1,000,000,000,000

= 10¹²

---------------------------

U.S National debt currently stands at:

$ 18.1 x 10¹²

*What information would be lost? Well firstly the 0's. The 0's put the size of the number into perspective. The word "trillion" would also be taken out of the picture, once again altering the perspective of the number.

Personally I'd prefer to hear "18.1 Trillion Dollars". Sounds more interesting.

Answer:

The fraction of male student who play sport is $\frac{3}{4}$

Step-by-step explanation:

Given as :

Out of the total number of students , the fraction of male = $\frac{2}{3}$ of total number of students

Let the total number of students = x

So, The fraction of male student = $\frac{2}{3}$ of x

I.e The fraction of male student = $\frac{2 x}{3}$

Again

The number of students who play sports = $\frac{1}{2}$ of total number of students

Or, The number of students who play sports = $\frac{1}{2}$ of x

Or, The number of students who play sports = $\frac{x}{2}$

Let The total number of male student who play sport = y

So, According to question

$\frac{2 x}{3}$ of y = $\frac{x}{2}$

I.e $\frac{2 x}{3}$ × y = $\frac{x}{2}$

or, y = $\frac{\frac{x}{2}}{\frac{2 x}{3}}$

∴ y = $\frac{3}{4}$

So, The total number of male student who play sport = y = $\frac{3}{4}$

Hence ,The fraction of male student who play sport is $\frac{3}{4}$ Answer

Answer:

a. a reflection over the x-axis and then a reflection over the y-axis

Step-by-step explanation:

If you plot it on a graph (you can use Desmos), you can see the triangles and only a. a reflection over the x-axis and then a reflection over the y-axis makes sense.
