A) 8.9
Triangle is half of a square, so a square has double the area of the triangle.
40 x 2 = 80
Area is the square root of 80.
Square root of 80 = about 8.9
x = 8.9
Answer:
The expression will be 
and its value is 8.
Step-by-step explanation:
We are asked to write the expression and the value of “six less than the quotient of a number and two, increased by ten”.
If the number is n, then the expression will be .
Now, if the value of n is 8 then the value of the expression will be 
(Answer)
4.5/0.15=30

Rearrange the product
(5.91 * 10^(-3)) * (8.7 * 10^10)
as
(5.91 * 8.7) * (10^(-3) * 10^10)
We have 5.91 * 8.7 = 51.417, and 10^(-3) * 10^10 = 10^(10 - 3) = 10^7, so the original product above reduces to
51.417 * 10^7
We can "add" powers of 10 by moving the decimal place to the left:
51.417 = 5.1417 * 10
so that
51.417 * 10^7 = (5.1417 * 10) * 10^7 = 5.1417 * 10^8
