Combustion in chemistry we can use a system of linear equations to determine the coefficients neces- sary to balance a chemical equation. for example, the complete combustion of propene (cshe) with oxygen (o2) results in carbon dioxide (co2) and water (h2o). because the quantity of each element is conserved, we must have the same quantities of carbon (c), oxygen (o) and hydrogen (h) on each side of the following chemical equation: a(c3hs) b(02) c(co2) + d(h20) where the coefficients a, b, c, d are how many of each molecule is present. (a) write the equation describing the conserved quantity of each type of chemical. you will have 3 equations in 4 unknowns. the equation for conserved oxygen atoms is given as an example: 2b = 2c + d ? 2b-2c-d = 0.

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10

the answer is c
