Answer:

425

Step-by-step explanation:

Let the original population of blackbirds be x.

<u>Original population</u>              <u>decreases by</u>                   <u>New population</u>

          100                                     24                                       76

            x                                        24                                     323

<u>Now we can make an expression like this.</u>

100  ⇒  76

x     ⇒   323

And now let us use cross multiplication and solve for x.

<u>Let us solve it now.</u>

323 × 100 = 76x

32300 = 76x

<u>425</u>=  x

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).
