Maria keeps her four stuffed bears lined up on a shelf over her bed how many arrangements of the bears are possible?
The answer is 4! (4 factorial), the same as 4x3x2x1, which equals 24 combinations. The answer is 24 and this is how: A b c d A b d c A c d b A c b d A d c b A d b c B c d a B c a d B d a c B d c a B a c d B a d c C d a b C d b a C a b d C a d b C b d a C b a d D a b c D a c b D b c a D b a c D c a b D c b a
What is b plus b plus b plus c plus c plus c plus c?
b+b+b+c+c+c+c =3b+4c
What is the negation of B is not between A and C?
The negation of B is not between A and C is = [(A < B < C) OR (C < B < A)] If A, B and C are numbers, then the above can be simplified to (B - A)*(C - B) > 0
Is it possible to use the associative property with subtraction?
No. There is a property of numbers called the distributive property that proves this wrong. a- ( b - c) is NOT the same as (a-b) -c because: a-(b-c) = a-b+c by the distributive property a-b+c = (a-b) + c by the definition of () (a-b)+c is not always equal to (a-b)-c
What are the property of addition and multiplication?
The properties of addition are: * communicative: a + b = b + a * associative: a + b + c = (a + b) + c = a + (b + c) * additive identity: a + 0 = a * additive inverse: a + -a = 0 The properties of multiplication: * communicative: a × b = b × a * associative: a × b × c = (a × b) × c = a × (b × c) * distributive: a × (b + c) = a × b + a × c * multiplicative identity: a × 1 = a * multiplicative inverse: a × a^-1 = 1
Which is the second layer of a soil profile?
Soil has distinct layers referred to as horizons. The first layer is called O horizon, followed by A horizon, B horizon, and C horizon.
Is soil horizon a layer of soil?
When soil is cut vertically different layers are seen called horizons which are named A ,B ,C etc.
How many soil horizons is there?
there are 5 soil horizons o,a,b,c,and r horizon
What is the layer of soil called?
Layers of soil are called horizons and labeled as O, A, E, B, C, and R. The top layer or horizon is O. It is made up of organic matter, and can be called topsoil.

What are the constituent parts of the soil profile?
O,A,B,C and R-horizons
What is the correct order of the different soil horizons?
c horizon a horizon then b horizon
Rock horizons in order?
A - Topsoil B - Subsoil C - Weathered Rock Bedrock
Which soil layer contains the most humus?
the O-Horizon is the topmost soil so it has the most humus
