Answer:
Correct answer is
Step-by-step explanation:
As per the given diagram, we know the following details:
Height of the triangular pyramid is <em>14m</em>.
<em>Side of base</em> = <em>10m
</em>
Height of Triangular base = <em>8.7m</em>
Formula for <em>surface area of triangular pyramid</em>:
(Triangular base is shown in the dotted lines in the question figure.
The other 3 triangles are the side triangles.)
We know that,
Hence correct answer is .
Answer:
v= 2.54. the answer. Thanks
it woud be a fraction. the fraction would be 88/100 or 22/25 in simplest form
Distance to the cabin is 'D' .
Distance = (speed) x (time)
Distance going = 30 H
Distance coming back = 36 (H - 1)
Distance is the same in both directions.
30H = 36(H - 1)
Eliminate parentheses: 30H = 36H - 36
Add 36 to each side: 30H + 36 = 36H
Subtract 30H from each side: 36 = 6H
Divide each side by 6 : 6 = H
It took 6 hours to go, 5 hours to come back,
and the trip was 180 miles each way.
6 x 30 = 180
5 x 36 = 180 yay !
Notice that 180 is the least common multiple (LCM)
of 30 and 36 . I'll bet that could have helped us if
we were all wide awake when we read the question.
