Interest due on 1200 at 8% for 240 days

kompoz [17]

Let us use 360 days for the 1-year term.

principal = 1,200

interest rate = 8% unless otherwise stated, this rate is per annum or annual rate.

term = 240 days

Simple Interest = Principal * interest rate * term

S.I = 1,200 * 8% * 240/360

S.I = 1,200 * 0.08 * 0.667

S.I = 64.032 rounded off to 64

The interest due 1200 at 8% rate is 64 in 240 days.

Hope that helps and feel free to ask me more questions :)

Which of the following correctly expresses sin (70) + sin(30) as a product?

JulsSmile [24]

Answer:

2sin50 cos20

Step-by-step explanation:

We need to write sin (70) + sin(30) as a product. The formula used here is :

$\sin A+\sin B=2\sin (\dfrac{A+B}{2})\cos(\dfrac{a-b}{2})$

Here, A = 70 and B = 30

So,

$\sin 70+\sin 30=2\sin (\dfrac{70+30}{2})\cos(\dfrac{70-30}{2})\\\\\sin 70+\sin 30=2\sin 50\cos20$

So, the value of sin (70) + sin(30) is 2sin50 cos20. Hence, the correct option is (c).
