Answer:
The length of the runway = 12090 feet
Step-by-step explanation:
The formula involving the area of a rectangle is
![A=wl](https://tex.z-dn.net/?f=A%3Dwl)
here
Given
Area A = 1,934,400 square feet
Width w = 160 w
Length l = ?
Using the formula
![A=wl](https://tex.z-dn.net/?f=A%3Dwl)
substituting the values
1,934,400 = 160 × l
l = 1,934,400 / 160
l = 12090 feet
Therefore, the length of the runway = 12090 feet
Answer: i
Step-by-step explanation:
It is imaginary, since if you try squaring numbers, ex: -1, 1,0,2 you always get a number bigger or equal to 0.
For years mathematicans argued weather the square root of -1 (or any negative number) should exist.
Then one day, a mathematician proposed a soulution, the square root of -1 could be i. Everyone liked that and so now the square root of -1 is i
The volume of a cone is 1/3 times the area of the base times the height.
So the area of the base would be pi times the radius squared, or 3.14 * 3.2^2, which is 32.1536.
Next you multiply 32.1536 by the height(5.8) to get 186.49088.
Then you divide that by 3 to get 62.1636267, rounded to the nearest tenth of an inch is 62.2 inches cubed.
The given equation is: 4 + 3x + (x.2)
As you can notice, in the parenthesis, we have a multiplication between the variable x and the number 2. Since we can't multiply a variable with a number, x.2 becomes 2x. So the reason for statement 2 is multiplication.
Hope this helps! :)
Answer:
yes
no
no
yes
no
Step-by-step explanation:
7/20 + 3/5 = 19/20 (yes/no) | it goes through
3/5 + 3/10 = 3/15 (yes/no) | doesn't go through
1/2 + 2/3 = 3/5 (yes/no) | doesn't go through
1/10 + 1/2 = 3/5 (yes/no) | it goes through
3/5 + 1/20 = 9/20 (yes/<u>no</u>) |<em> doesn't go through</em>
