27 cubic feet.
You can get this because the surface area formula shows that each edge is 3ft. the area would be length x width x height, which are all 3.
Answer:
150 m
Step-by-step explanation:
So the scale of the model is 1 cm = 5 m, and the model is 30 cm long. We can set this up as two fractions, then cross-multiply, like so:
1 cm/30 cm = 5 m/x m
1 * x = x
30 * 5 = 150
Now, set the two products equal to each other. Normally we'd have to simplify, but x is already on its own, so we have our answer:
x = 150 m
Answer:
4.18
Step-by-step explanation:
8.34-4.16
Answer:
See below.
Step-by-step explanation:
(a) A sequence is an ordered list of numbers whereas a series is the sum of a list of numbers.
(b) A series is convergent if the sequence of partial sums is a convergent sequence (that is tends to a limit). A series is divergent if it is not convergent.
Answer:
x = 25
Step-by-step explanation:
The interior angle adjacent to the 123° angle is supplementary to it.
Its measure is 180° - 123° = 57°
The sum of the measures of the interior angles of a polygon is
(n - 2)180° = (4 - 2)180° = 2(180°) = 360°
3x + 7 + 96 + 5x + 57 = 360
8x + 160 = 360
8x = 200
x = 25
