Answer:
The effect of doubling all the dimensions of a triangular pyramid will have on the volume of the pyramid is to increase it by 8 times.
Step-by-step explanation:
i) volume of triangular pyramid = 
Area height
= (Base of triangle perpendicular height of triangle) height
ii) if we double all the dimensions then the three variables((Base of triangle, perpendicular height of triangle, height of pyramid) will be doubled
and the volume of the new pyramid will be 8 times that of the original one.
The product of (x1)^2 is 20
we have
----> inequality 1
The solution of the inequality 1 is the shaded area below the solid red line
The solution is the region D and region C
-----> inequality 2
The solution of the inequality 2 is the shaded area above the solid blue line
The solution is the region B and region C
The solution of the system is the common area
so
The solution is the region C
see the attached figure
therefore
the answer is the option C
Region C
Answer:
E. Leela Chitnis
Step-by-step explanation:
The 3 inside angles of a triangle need to equal 180 degrees.
The angle below the 100 degrees would be 180-100 = 80 degrees.
Now you have 80 and 70, which equals 150 degrees.
Angle X = 180 -150 = 30 degrees
