Answer:
342.24 units²
Step-by-step explanation:
The area of one of the 8 triangular sections of the octagon is ...
A = (1/2)r²·sin(θ) . . . . . where θ is the central angle of the section
The area of the octagon is 8 times that, so is ...
A = 8·(1/2)·11²·sin(360°/8) = 242√2
A ≈ 342.24 units²
We know that V = a^3 and that it's 1000 cubic meters (or unit cubes as long as one unit cube is 1x1x1m). We can write the calculation as attached below. The result (dimensions of one cube house) is<span> 10x10x10 meters</span>.
Let U = {1,4,6, 7, 8, 10, 11, 14, 17}. Determine the complement of the set {1, 4, 6, 7, 8, 10, 14, 17}.

Answer:
{11}
Step-by-step explanation:
complement means not the elements of the set only the remaining elements of universal set
11 is remaining so 11 is the answer

Just divide 78 with 11, 7.090909090909091.
Answer:
2x+y+1=0
Step-by-step explanation:
this is a first degree equation with two unknown variables, x and y. they are referred to as linear equation and are typically represented in slope intercepts form, y=mx+b, where m is the slope of the line and b is the y intercept. So you want to set the equation equal to y by isolating it to one side of the equation.
Subtract all term other than y (in this case, 2x and 1) from both sides of the equation.
2x+y+1-2x-1=0-2x-1
y=-2x-1
