Answer:
B. Rotate 180° clockwise around (8, 4) and reflect across the line x=8.
Step-by-step explanation:
The figure is symmetrical (order 2) about the point (8, 4), and about the lines x=8 and y=4.
Hence, rotation 180° about the point (8, 4) makes the figure look unchanged. Since the figure is also symmetrical about the line x=8, reflecting it across that line will also leave the figure unchanged.
__
Any of the other transformations have the effect of translating the figure somewhere else.
Answer:
30 questions
Step-by-step explanation:
if you cross multiply and divide like this,
27 x 100 = 2700
2700 / 90 = 30
you'll get ; 30 !
Answer:
V = 60 m3
Step-by-step explanation:
Volume of a square pyramid:
V = (1/3)a2h
Slant Height of a square pyramid:
By the pythagorean theorem we know that
s2 = r2 + h2
since r = a/2
s2 = (1/4)a2 + h2, and
s = √(h2 + (1/4)a2)
This is also the height of a triangle side
Keep adding 5 to the first term as many times as you need. 15-10=5. So if you add 15 then subtract 10, you are really just adding 5 to 4 first =9,14,19, etc
