<span>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
= 10</span>¹²
<span>
---------------------------
U.S National debt currently stands at:
$ 18.1 x 10</span>¹²
<span>
*<em>What information would be lost?</em> 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.</span>
Answer:
A. 220
Step-by-step explanation:
To find the total surface area of a square pyramid, you have to find the area of the base and all of the sides and add them together.
To find the area of the base:
Since the base is a square, all we have to do is multiply the length by itself.
10 * 10 = 100
The base is 100 square centimeters
To find the area of the sides:
Since the sides are triangles, we have to multiply the length times the height and divide it by 2.
10 * 6 = 60
60/2 = 30
The area of one side is 30 square centimeters
To find the total surface area:
Add the area of all 4 sides and the area of the base together to find the total surface area.
4(30) + 100 = surface area
120 + 100
220 = surface area
The surface area is A. 220 square centimeters.
Integers are whole numbers.....so 15.6 rounded to the nearest whole number is 16.
