How many square feet will a yard of river rock cover?
The answer depends on the depth of the layer.1 yard of river rock actually means "1 cubic yard" of river rock.A cubic yard is 3 ft x 3 ft x 3 ft = 27 cubic ftIf you want a layer that is 3 ft deep, it would cover 9 square ft (i.e. 3 ft x 3 ft = 9 sq ft)If you want a layer that is 4 inches deep, it would cover 81 square ftx^2 * (4"/12") = 27x^2 = 27 * 12/4 = 81x = sqrt (81)x = 99 ft x 9ft = 81 sf
What is the length of the shadow cast by a 63 foot high pole if a 27 foot high pole casts an 18 foot shadow?
Assuming the two poles are parallel . Then use Similar Triangles. 27/18 is to 63/x Equating 27/18 = 63/x Algebraically rearrange x = (63/27) X 18 Cancel down (reduce) by '9' x = (63/3) X 2 Cancel down (reduce by '3') x = (21/1) X 2 x = 42/1 = 42 ft. (Which is the length of the shadow created by the 63 ft. pole).

What is 10x plus 22-37x plus 1?
It is: 23-27x when simplified
What is 27x cubed?
27x cubed, written mathematically as 27x³, represents the expression where 27 is multiplied by the cube of the variable x. This can be expanded as 27 * x * x * x, which equals 27x * x². In simpler terms, it signifies that the variable x is raised to the third power and then multiplied by 27.

3x2 + 27x +60
What is the cubed root of 27x to the 12th power?
cube root of 27 = 3, so 3^12 = 531 441 * * * * * If the question is about 27x, rather than 27, the answer is as follows: cuberoot(27x12) = (27x)12/3 = (27x)4 = 531441x4
What is 3x cubed times 3x cubed?
Your question is ambiguous. (3x)^3 times (3x)^3 = 27x^3 times 27x^3 = 729x^6 or, if you meant 3x^3 times 3x^3 = 9x^6
What is the slope-intercept form of 9 plus 9y equals 27x?
9 + 9y = 27x -9 -9 9y = 27x - 9 9y/9 = 27x/9 - 9/9 y = 3x -1
