Since there are 3 sides and each of those 3 sides are 9 cm, you would multiply 9*3 and your answer would be 27 cm.
Answer:
$25
Step-by-step explanation:
500 mins = $35 (fixed + per minute charge)
1500 mins = $55 (fixed + per minute charge)
If we let per minute charge be "m"
and
let fixed charge be "f"
we can write 2 equations as:
35 = 500m + f
and
55 = 1500m + f
Now,
We re-write both equations in terms of f and equate both expressions:
f = 35 - 500m
and
f = 55 - 1500m
Equating:
35 - 500m = 55 - 1500m
-500m + 1500m = 55 - 35
1000m = 20
m = 20/1000
m = 0.02
Now we find f, what we are looking for:
f = 35 - 500m
f = 35 - 500(0.02)
f = 25
So, the fixed charge is $25
Answer:

Step-by-step explanation:
<em>Shino's formula will work for any prism</em>.
Angelo's formula will work for any prism whose base area can be found by ...
B = (1/2)ew
<em>Angelo can use this formula for a triangular prism</em>.
__
For a triangular prism, both may be correct.
For a prism of another shape, Shino is correct. (Angelo may also be correct, depending on the variable definitions.)
D. 0.65 since that equals 65% and 0.35 or 35% would equal 100
