Licemer1 [7]
For this you'll want to draw out Triangle ABC and label it as the problem gives you.

Draw a similar triangle to the first one you drew and label it the exact same way as "ABC" and then match the measurement "AB" to "HJ".

Hope this helps.

You are fencing a rectangular puppy kennel with 25 ft. of fence. The side of the kennel against your house does not need a fence
Vikentia [17]
W = width
l = length = 9
Perimeter = 2*w+2*l
Normally you would face the whole perimeter but "t<span>he side of the kennel against your house does not need a fence.</span>" So you actually fence 2*w+1*l

2w+l=25
2w+9=25
2w=16
w=8

The dimensions  of the kennel are:
w=8 ft
l=9ft

Semmy [17]

Answer:

The price of elasticity of demand is 2.59

Step-by-step explanation:

*<em> Lets explain how to solve the problem</em>

- During the past year the price of a laptop computer fell from

 $2950 to $2450

- During the same time period consumer sales increased from

 430000 to 619000 laptops

- <em>We need to find the price of elasticity of demand</em>

- <u><em>The rule of price elasticity is:</em></u>

  price elasticity = percentage of change in the quantity ÷

  percentage of change in price

* <em>Lets calculate the percentage of change in quantity and the </em>

<em>  percentage of chance in price</em>

∵ The percentage of increasing of quantity = (new - old)/old

∵ New = 619000 and old = 430000

∴ The percentage of increasing of quantity =

   \frac{619000-430000}{430000}*100=43.95%

∵ The percentage of decreasing of price = (old - new)/old

∵ New = $2450 and old = $2950

∴ The percentage of decreasing of price =

   \frac{2950-2450}{2950}*100=16.95%

- <em>Lets substitute these values in the equation above</em>

∴ Price of elasticity of demand = 43.95% ÷ 16.95% = 2.59

* The price of elasticity of demand is 2.59
