Answer:

425

Step-by-step explanation:

Let the original population of blackbirds be x.

Original population decreases by New population

100 24 76

x 24 323

Now we can make an expression like this.

100 ⇒ 76

x ⇒ 323

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

Let us solve it now.

323 × 100 = 76x

32300 = 76x

425= x

So I'm assuming the answers have to be the same?? if that's the case, 457×32=15904 so you would subtract 994 from 15904. That means the answer is 14,910. I hope this helped!

Find the area A of the sector of a circle of radius 50 feet formed by the central angle

kozerog [31]

Answer:

$A=6250\ feet^2$

Step-by-step explanation:

Given that,

The radius of circle, r = 50 feet

The central angle, $\theta=5\ radian$

We need to find the area of the sector of a circle. The formula for the area of sector is given by :

$A=\dfrac{1}{2}r^2\theta\\\\=\dfrac{1}{2}\times 50^2\times 5\\\\A=6250\ feet^2$

So, the area f the sector of the circle is $6250\ feet^2$ .
