12 subtract 2 times 5 plus 7 is 9
Answer:
n = 3.
Step-by-step explanation:
nth root(54 . x^6 . y^ 12) = 3 x^2 y^4 nth root of 2
(54 . x^6 . y^ 12)^1/n = 3 x^2 y^4 2^1/n
54^1/n . (x^6)^1/n . (y^12)^1/n = 3 x^2 y^4 2^1/n
Consider the terms in x:
(x^6)^1/n = x^2
x^6/n = x^2
Therefore 6/n = 2 and n = 3.
Check this out with the constants in the expressions:
54 ^ 1/n = 3 * 2^1/n
54 ^ 1/3 = 27^1/3 * 2^1/3 = 3 * 2 1/3
- Checks OK.
Answer:
736 Newtons
Step-by-step explanation:
Given
Pressure =
Multiply both sides by Area
Area × Pressure = Force
Area = 2.3 × 1.6 = 3.68 m², hence
Force = 3.68 × 200 = 736 Newtons
Answer:
13.0 trillion pounds of carbon dioxide
Step-by-step explanation:
5.877 ÷ 0.4536 = 12.9563492063
rounded to 1 decimal place =
13.0 trillion pounds of carbon dioxide
Answer:
The first two.
Step-by-step explanation:
See that L is 600mm MORE than W.
From there, you can note that L = W+600
or rearrange the formula and get W= L-600
Then, see that the perimeter of a flag is 2L + 2W
(Because there are two four sides to a rectangle, 2 width, 2 length)
It must total to be 5 meters, or 5000mm
Thus,
2L + 2W = 5000
