$220\to\boxed{200}$

220 rounds to 200 because the number that matters is the number to the right of the hundreths place, the tenths. In the tenths place is 2, which is under 5, so we don't round up, we stay at 200, not 300

In a pen of goats and chickens, there are 40 heads and 150 feet. How many goats and chickens are in the pen?

s2008m [1.1K]

Hey there!!

A chicken has 1 head and 2 feet . A goat has 1 head and 4 feet

For heads, total = 40

Let us take the number of chickens as ' x ' and goats as ' y '

x + y = 40 ------------- ( 1 )

2x + 4y = 150 ----------- ( 2 )

Multiply the first equation with 2

2x + 2y = 80

2x + 4y = 150

Subtract the first equation from the first

2y = 70

y = 35

Number of goats = 35

substitute this in other equation

x + y = 40

x + 35 = 40

x = 5

Number of chickens are 4

Hope it helps!

Polynomial equation when zeros are -4, -2, 1, 4

jek_recluse [69]

<h2>The required poynomial equation is $x^{4}+x^{3}-18x^{2}-16x+32$ .</h2>

Step-by-step explanation:

Given,

The zeros of the polynomial are - 4, - 2, 1 and 4

To find, the polynomial equation = ?

We know that,

The polynomial equation = (x - A)(x - B)(x - C)(x - D)

= (x + 4)(x + 2)(x - 1)(x - 4)

= [(x + 4)(x - 4)] [(x + 2)(x - 1)]

= ( $x^{2}-16$ )( $x^2-x+2x-2$ )

= ( $x^{2}-16$ )( $x^2+x-2$ )

= $x^{4}+x^{3}-2x^{2}-16x^{2}-16x+32$

= $x^{4}+x^{3}-18x^{2}-16x+32$

Thus, the required poynomial equation is $x^{4}+x^{3}-18x^{2}-16x+32$ .

Maybe the price of the fourth pair is like about fifty dollars because the average of the four shoes are fifty dollars. The other shoe pairs that he/she bought is thirty five, forty and fifty dollars.

So, the price is about fifty dollars.
