Answer:
$ 158.95
Step-by-step explanation:
Reduction = 25% of 199
= 0.25 * 199
= $ 49.75
Price of the tablet after reduction = 199 - 49.75 = $ 149.25
Sales tax = 6.5% of 149.25
= 0.065 * 149.25

Total price that he need to pay = 149.25 + 9.70
= $ 158.95
Answer:
2.7 PM
Step-by-step explanation:
Since, the rate of spread is proportional to the product of fraction y of people who have heard the rumour and the fraction who have not heard,
Integrating both sides,
If t = 0, ( at 8 AM ), y =
Now, at noon, i.e t = 4, y =
If
Using graphing calculator,
t ≈ 6.722,
Hence, after 6.722 hours since 8 AM, i.e. on 2.7 PM ( approx ) the 90% of the population have heard the rumour.
Answer:
x³ - 3x² + 10x + 3 +
Step-by-step explanation:
Using synthetic division to divide by x - 1
1 | 1 - 4 13 - 7 3
↓ 1 - 3 10 3
----------------------------
1 - 3 10 3 6 ← remainder = 6
--------------------
↑ quotient
= x³ - 3x² + 10x + 3 +
