Answer:
The first one and the second one
Step-by-step explanation:
25 = 5*5
405 = 81*5
therefore, 25/405 = (5*5)/(81*5)=5/81
Answer
Step-by-step explanation:
Even numbers are multiples of 2, and more generally, multiples arise ... An even number can be written as the sum of two equal whole numbers. ... Yet when their sum 63 is divided by 6, the remainder is 3, and is not 4 + 5 = 9. ... For example, in the case above of 4 and 6, one common multiple is 4 × 6 = 24, but their lowest ...
Answer: height of the tower is 1064 feet
Step-by-step explanation:
We want to determine the height of the tower.
Assuming her line of sight of the top of the tower is a straight line, then a right angle triangle is formed. The height, h of the tower represents the opposite side of the triangle. Her distance from the foot of the tower represents the adjacent side of the triangle.
To determine h, we would apply the tangent trigonometric ratio which is expressed as
Tan θ = opposite side/adjacent side
Therefore,
Tan 85.7 = h/80
h = 80tan 85.7
h = 1064 feet
<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

*<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>
