Baileys rectangular dog pen for his Irish setter must have an area of 300 square feet. Also, the length must be 10 feet longer t
Naily [24]
Area of rectangle = length × width
300 = (x+10) × x
300 = 10x + x^2
Now we have the equation y=x^2 + 10x - 300
We can factor this equation to get our zeroes, which are:
-5(1+sqrt(13)),
5(sqrt(13)-1)

We only use the positive zero because we can't have a negative dimension.

Your width would be:
5(sqrt(13)-1)

Your length would be:
5(sqrt(13)-1) + 10

Look at this triangle work out length BC
Andreas93 [3]

Answer:

The length of BC is √105 cm or 10.2 cm.

Step-by-step explanation:

You have to apply Pythagoras Theorem, c² = a² + b² where c represents hypotenuse, a and b are the sides :

{c}^{2}  =  { a}^{2}  +  {b}^{2}

let \:a =BC \:, \:  b = 8 \: , \: c = 13

{13}^{2}  =  {BC}^{2}  +  {8}^{2}

169 =  {BC}^{2}  + 64

{BC}^{2}  = 169 - 64

{BC}^{2}  = 105

BC =  \sqrt{105}

BC = 10.2 \: cm \: (3s.f)

Find the break-even point for the firm whose cost function C and revenue function R are given.
katrin2010 [14]
The solution is 
to find x, C(x) = <span>R(x)
</span>5x + 10,000 = <span>15x
</span>         10,000 = <span>10x, so x = 1,000</span>

an employee is selected from a staff of 10 to super- vise a certain project by selecting a tag at random from a box containing 1
USPshnik [31]

Probability that the number drawn is less than 4 is given by 0.3

<h3>What is probability?</h3>

The likelihood of an event happening is gauged by probability.

The probability might be between 0 and 1, where 0 denotes an impossibility and 1 denotes a certainty.

The overall chance of every event in a sample space is 1.

Let random variable X represent the number of the drawn tag.

Since the simple space consists of 10 equally likely events

S = {1,2,3,4,5,6,7,8,9,10}

The formula for probability distribution is given by:

f(x) = { (1/10) for x = 1,2....10,    else 0 elsewhere

since, each number can equally likely occur, therefore

P(x) = 1/10 = 0.1

Probability that the number drawn is less than 4 is given by:

P(x<4) = P(1) + P(2) + P(3)

           = 0.1 + 0.1 + 0.1

           = 0.3
