The length of a rectangle is six times its width. If the area of the rectangle is 486 in 2 , find its perimeter.

seraphim [82]

w - width

6w - length

486 in² - area of the rectangle

(w)(6w) = 6w² - area of the rectangle

The equation:

6w² = 486 <em>divide both sides by 6</em>

w² = 81 → w = √81

w = 9 in

l = 6w → l = (6)(9) → l = 54 in

The perimeter: P = 2l + 2w

P = 2(54) + 2(9) = 108 + 18 = 126 in

<h3>Answer: The perimeter is 126in</h3>

A shipment of 12 microwave ovens contains 3 defective units. A vending company has ordered 4 of these units, and because all are

pishuonlain [190]

P(defective) = 3/12 = 1/4
P(good) = 1 - 1/4 = 3/4
$P(2\ good)=4C2\times0.75^{2}\times0.25^{2}=0.211$
$P(3\ good)=4C3\times0.75^{3}\times0.25=0.422$
$P(4\ good)=0.75^{4}=0.316$
The probability that at least 2 units are good is given by:
P(2 good) + P(3 good) + P(4 good) = 0.211 + 0.422 + 0.316 = 0.949.

What value of x is in the solution set of 3(x-4)≥6x+2

Sophie [7]

Answer:

x <= - 4 2/3

Step-by-step explanation:

3(x-4) ≥ 6x+2

Distributive property

3x - 12 ≥ 6x+2

-12 ≥ 3x + 2

re-write

3x + 2 <= -12

3x <= -14

x <= -14/3

x <= - 4 2/3
