Answer:
14. X = 1236000(1.013^t)
1,406,413.169 at t = 10
15. X = 752000 × (0.86^t)
49,795.48457 at t = 18
16. X = 18000 × 0.75^t
5,695.3125 at t = 4
Step-by-step explanation:
14.
X = 1236000 × (1 + 1.3%)^t
X = 1236000(1.013^t)
At t = 10,
X = 1236000 × 1.013¹⁰
= 1406413.169
15. 752000 × (1 - 1.4%)^t
X = 752000 × (0.86^t)
At t = 18
X = 752000 + 0.86¹⁸
= 49795.48457
16.
X = 18000 × (1 - 25%)^t
X = 18000 × 0.75^t
At t = 4
X = 18000 × 0.75⁴
X = 5695.3125
Answer:
9
Step-by-step explanation:
2 raised by 3 = 8
4 * 2 = 8
8 + 8 = 16
16 - 7 = 9
5/8 = x/72 where x is the perimeter of the smaller rectangle.
8x = 5 * 72
x = 5 * 9
x = 45
Answer:
Option D is correct.
Step-by-step explanation:
Given, the side of a cube is 7 cm.
Total surface area of cube side = ![6 {s}^{2}](https://tex.z-dn.net/?f=6%20%7Bs%7D%5E%7B2%7D%20)
![= 6 \times 7 \times 7](https://tex.z-dn.net/?f=%20%3D%206%20%5Ctimes%207%20%5Ctimes%207)
![= 294](https://tex.z-dn.net/?f=%20%3D%20294)
∴ the total surface area of cube is ![294 {cm}^{2}](https://tex.z-dn.net/?f=294%20%7Bcm%7D%5E%7B2%7D%20)
