Answer:
Answer:
85t
Step-by-step explanation:
1. Volume of a cone: 1. V = (1/3)πr2h 2. Slant height of a cone: 1. s = √(r2 + h2) 3. Lateral surface area of a cone: 1. L = πrs = πr√(r2 + h2) 4. Base surface area of a cone (a circle): 1. B = πr2 5. Total surface area of a cone: 1. A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

Answer:
5 Outer and 1 lone pair
Step-by-step explanation:
A square pyramidal shape results when one of the bonds of an octahedron structure is occupied by a lone pair.
Hence there are 5 bonded atoms and one lone pair. The hybridization about the central atom is 
.
One of the most common example is Xenon tetraflouride. 
. Looking at its structure we can see that it has 5 pairs of outer atoms and one lone pair. With its coordination number 5. The shape of the orbitals is octahedral.
Answer:
x = 
Step-by-step explanation:
Given expression is,
x =
Answer:
(2 - x ) = 1 / 10
Step-by-step explanation:
1 / 5 + 2 / 3 (2 - x ) = 4 / 15
Subtract 1 / 5 from both sides
2 / 3 (2 - x ) = 4 / 15 - 1 / 5
2 / 3 (2 - x ) = 1 / 15
Multiply 3 / 2 on both sides
(2 - x ) = 1 / 15 * 3 / 2
(2 - x ) = 1 / 10
If the last day is y. and then the answer will be y=120-x
