Answer:
B
Step-by-step explanation:
in parallel lines, corresponding angles on each line must be the same.
You can also tell that 2 obtuse angles aren't supplementary as they don't add up to 180 degrees.
Answer:
80000bacterias
Step-by-step explanation:
Volume of the bedroom= length ×width× height
Given
Length = 2m
Width = 4m
Height= 2.5m
Volume of the bedroom= 2×4×2.5
Volume of the bedroom = 20m³
Given that;
4000bacterias = 1m³
x bacteria = 20m³
Cross multiply
x =4000×20
x =80000
Hence 80000 bacteria's are present in Bill's room
We can split the shape into a square of lengths, 12*12 and a triangle of lengths, 8*12. (This shape is not to scale BTW) The area of the square is 144, and the area of the right triangle is 48, so the answer is 192 square units squared.
Another way of doing this is using the trapezoid area formula, which is
(b1 + b2)/2 * h. So 32/2 * 12 = 16*12 = 192.
