Sara has a circular fence around her dog house. Each day when she comes home from
larisa86 [58]

Answer:

226.2 feet

Step-by-step explanation:

The fence around the dog's house is a circle, with a radius of 12 meters.

To calculate the distance the dog runs, we need to find the circumference of that circle, which is given by the formula:

C = 2 π r, since we know r, the calculation is easy:

C = 2  π 12 = 24 π = 75.4 feet.

The dog makes three laps around the circle before calming down... so he runs 3 times 75.4 feet.

Dogs run = 3 x 75.4 ft = 226.2 feet

if alpha and beta are zeros of the polynomial x² - 6 X + k find k such that (alpha+beta)²-2alha beta =40​
lidiya [134]

Answer:

k = - 2

Step-by-step explanation:

Given α and β are the zeros of x² - 6x + k = 0 , with

a = 1, b = - 6 and c = k , then

α + β = - \frac{b}{a} = - \frac{-6}{1} = 6

αβ = \frac{c}{a} = \frac{k}{1} = k

Then solving

(α + β)² - 2αβ = 40

6² - 2k = 40

36 - 2k = 40 ( subtract 36 from both sides )

- 2k = 4 ( divide both sides by - 2 )

k = - 2

What is the solution: <br><br> 256x + 2 = 43x + 9
ruslelena [56]

<u>Answer:</u>

x = \bf \frac{7}{213}

<u>Step-by-step explanation:</u>

To find the solution to the equation, we have to rearrange the equation to make x the subject:

256x + 2 = 43x + 9

⇒ 256x + 2 - 2 = 43x + 9 - 2             [Subtracting 2 from both sides]

⇒ 256x = 43x + 7

⇒ 256x - 43x = 43x + 7 - 43x           [Subtracting 43x from each side]

⇒ 213x = 7

⇒ \frac{213}{213}x = \frac{7}{213}                                       [Diving both sides by 213]

⇒ x = \bf \frac{7}{213}

What is 5% of 220? Show work please
luda_lava [24]
It is easier (for me anyway) to find 10% then work around that.
Following that path would mean that, by making a table:

100% = 220
10% = 22
5% (Which is half the 10) = 11
