The given scenario above is like a geometric sequence with r or common ratio being 1.05 and the first term being 31 square meters. The nth term of the sequence is calculated through the equation,
A15 = (A1)(r)^(n - 1)
Substituting,
A15 = (31)(1.05)^(15 - 1) = 61.3778 square meter
Therefore, the area covered by the spill after the 15th day is approximately 61.4 square meters.
Answer:
7
Step-by-step explanation:
find the surface area of the base of the triangular pyramid:
(base x height) / 2 = (4 x 3.5) / 2 = 7 in²
Let s = sale
Let h = hours
The ratio is s to h, which can be written as a fraction as 24/6.
The answer is 745. Doesn't math make sense ?
