Answer:
Different substances are made of different PARTICLES.
Some particles JOIN each other more than others, which means that space between the particles is very small.
Question 2: the answer is the first one
We know that the volume of a cone is given by the following relation:
V = (pi * r^2 * h)/3
where r is radius and h is height of the cone
In our case, radius is diameter divide by 2:
V = (pi * (8/2)^2 * 10) / 3 = 167.55 cubic inches
So the container holds 167.55 cubic inches
Answer:
-y^2 - 10 y - x^72 + -1
Step-by-step explanation:
Simplify the following:
-y^2 - 3 y - 5 - (x^36)^2 - 7 y + 4
Multiply exponents. (x^36)^2 = x^(36×2):
-y^2 - 3 y - 5 - x^(36×2) - 7 y + 4
36×2 = 72:
-y^2 - 3 y - 5 - x^72 - 7 y + 4
Grouping like terms, -y^2 - 3 y - 5 - x^72 - 7 y + 4 = -y^2 + (-3 y - 7 y) - x^72 + (4 - 5):
-y^2 + (-3 y - 7 y) - x^72 + (4 - 5)
-3 y - 7 y = -10 y:
-y^2 + -10 y - x^72 + (4 - 5)
4 - 5 = -1:
Answer: -y^2 - 10 y - x^72 + -1
