Answer:
She should have used One-half (9.4) (11.9) to represent the area of a single triangle
Step-by-step explanation:
The pyramid is composed by 4 triangles and 1 square
area of the square: base² = 9.4²
area of each triangle = 1/2*base*height = 1/2*9.4*11.9
surface area of the pyramid = 4*area of each triangle + area of the square = 4*(1/2*9.4*11.9) + 9.4²
The correct answer is
<span>D. The number of degrees in its supplement
The size of the sides and the rotation is irrelevant and would still keep the angle having the same size. The number of degrees in the supplement decides how big an angle is because the larger the supplementary angle the smaller the angle we're observing will be, and vice versa.</span>
First you have to solve both inequalities,
3x-1>8
3x>9
x>3
and the other one
2x≤4
x≤2
then you graph each one on the number line
the graph says or, so the solution can satisfy either equation
the solution would be all real numbers except three
the way to write it is x≠3
Answer:
slope = m = (0--3)/(14--4) = 3/18 = 1/6
y=mx + b
y =(1/6)x + b
0= (1/6)14 + b
b = - 14/6 = - 7/3
y = (1/6)x - 7/3
or
6y-x = -14
