Answer:
7x2
Step-by-step explanation:
7x2 is 14 and all the other ones equal 7
Multiply 0.000007 (7x10ˆ2) by 20,000,000,000,000 (2x10ˆ13)
<span>The answer is 140,000,000 (1.4x10ˆ8) meters</span>
If the letters are considered distinct, then the number of permutations is

.
If we count either C as the same character, then we would be double-counting - to correct this, we would simply divided by the number of ways we can choose C from the available characters, or

.
Answer is A
Triangle UVW ~ Triangle UWT ~ Triangle WVT
Let h,l, and w represent the height, length, and width of the building respectively
Then



The new value of h = 50m, but l remains the same.
That is l = 10m
Therefore

Hence, the width is 2.5m
