Step-by-step explanation:
We are considering of water.
We know that each mole of a substance weights equal to the substances' molar weight.
The molar weight of water ( ) is . This value is a standard and hence can be found from charts.
∴ Number of moles of water =
Answer:
12?
Step-by-step explanation:
3M x 4H = 12HM.
Answer:
x=8
Step-by-step explanation:
- Pythagorean Theorem Formula: a^2+b^2=c^2
- Let a be x, let b be 6, and let c be 10.
- Plug x, 6, and 10 into the equation - x^2+6^2=10^2
- Simplify 6^2 and 10^2 - x^2+36=100
- Subtract 36 from both sides - x^2=64
- Take the square root of x^2 and 64 to get x by itself - x=8
Answer:
(3, 1)
Step-by-step explanation:
Given the following constraints:
2x + 4y ≤ 10
x + 9y ≤ 12
x ≥ 0
y ≥ 0
We have to first graph the above constraints and secondly, we find the boundary points for the feasible region. This is done by plotting the graphs of 2x + 4y ≤ 10 and x + 9y ≤ 12.
From the graph, the following points satisfy the constraints:
(0,0)
, (3,1)
, (0,4/3)
, (5,0)
Given that:
P = x + 6y
For (0, 0): P = x + 6y = 0 + 6(0) = 0
For (3, 1): P = x + 6y = 3 + 6(1) = 9
For (0, 4/3) P = x + 6y = 0 + 6(4/3) = 8
For (5, 0) P = x + 6y = 5 + 6(0) = 5
