Answer:
2187/64
Step-by-step explanation:
first term (a) = 2
common ratio (r) = 3/2
8th term (t8) = ?
We know
Tn = ar^ n - 1
t8 = 2 * (3/2)^ 8 - 1
= 2 * 2187/128
= 2187/64
You need to find the total surface area of the rectangular prism. The top and bottom are 8(6), which equals 48. Since we want both the top and bottom, multiple 48 by 2 to get 96. The we need to calculate the remaining 4 sides. Two of them are 15(6), which is 90. Again, multiply by two since there’s two of those sixes to get 180. Finally, the last two sides are 15(8), which is 120. Add all of these numbers together to get 96+180+120=396. So she will need 396 cm^2 of fabric.

<span>A mathematical model is a description of a system using mathematical concepts and language. The process of developing a mathematical model is termed mathematical modeling.
</span><span>Mathematical modeling results in formulas that give exact values of real world phenomena over time.</span>
100 by 65 = 330 perimeter = 6,500 area
90 by 75 = 330 perimeter = 6,750 area
