Answer:
Water is stored in the following places: The lithosphere (the solid outer crust and upper mantle). In oceanic crust it is stored within the rock structure which it is composed of and in continental crust it is also found in rocks, minerals, and also in clay and as groundwater.
I say the lithosphere.
Step-by-step explanation:
or it can be
But new research suggests a different origin for the oceans: they simply seeped out of the center of the Earth. The finding, published in Science, suggests that a reservoir of water is hidden in the Earth's mantle, more than 400 miles below the surface.
Since 1/2 =2/4 = 4/8 = 5/10, only Mary drank less than half of her juice. 3/8 is less than 4/8
Answer:
The value of the expression is 1.
Step-by-step explanation:
The expression is:
![[(\frac{2}{3})^{0}]^{-3}](https://tex.z-dn.net/?f=%5B%28%5Cfrac%7B2%7D%7B3%7D%29%5E%7B0%7D%5D%5E%7B-3%7D)
Exponent rules:
Simplify the expressions as follows:
![[(\frac{2}{3})^{0}]^{-3}=[1]^{-3}](https://tex.z-dn.net/?f=%5B%28%5Cfrac%7B2%7D%7B3%7D%29%5E%7B0%7D%5D%5E%7B-3%7D%3D%5B1%5D%5E%7B-3%7D)
Thus, the value of the expression is 1.
Answer:
Bryan walks faster
Bryan was farther away from home when he started walking.
Step-by-step explanation:
Given the following :
Brendon's distance in feet from home 'y' in relation to the number of minutes walked 'x'
y = 7,920 − 270x
For bryan:
Minutes (x) - - - 0 - - - - - 15
Feet ( y) - - 8000 - - - 3800
General form of a linear equation :
y = mx + C
m = gradient / slope
m = (y2 - y1) / (x2 - x1)
m = (3800 - 8000) / (15 - 0)
m = -4200 / 15 = - 280
Intercept 'c' = 8000 (where line intersect the y axis), (since y = 8000, when x = 0)
Therefore,
Bryan's model:
y = 8000 - 280x
Comparing both functions :
Bryan has a greater speed ( from the gradient)
Bryan was farther away from home when he started walking ( intercept )
Answer: the system of linear equations has no solutions.
Step-by-step explanation:
The given system of linear equations is expressed as
2x -3y =1 - - - - - - - - - - - - -1
-4x+6y=-4 - - - - - - - - - - - - - 2
We would eliminate x by multiplying equation 1 by 2 and equation 2 by 1. It becomes
4x - 6y = 2
- 4x + 6y = - 4
Adding both equations, it becomes
4x - 4x - 6x + 6x = 2 - 4
0 = -2
Therefore, there is no solution to the system of linear equations
