A school wants to have a metal gate placed around it. However they only want to cover three sides of the school and they only ha
Fofino [41]

Answer:

Width = 139.445 ft and Length = 1721.11 ft or

Width = 860.555 ft and Length = 278.89 ft

Step-by-step explanation:

If the school has a rectangular shape, we have that its perimeter and area are:

Perimeter = 2*Length + 2*Width

Area = Length * Width

If we just want to cover 3 sides of the school, we can affirm that:

2000 = Length + 2*Width (eq1)

And the area is 240,000 ft2, so:

240000 = Length * Width (eq2)

From (eq1), we have that:

Length = 2000 - 2*Width

Using this value in (eq2), we have:

240000 = (2000 - 2*Width) * Width

240000 = 2000*Width - 2*Width^2

Width^2 - 1000*Width + 120000 = 0

Using Bhaskara's formula, we have:

Delta = 1000^2 - 120000*4 = 520000

sqrt(Delta) = 721.11

Width1 = (1000 + 721.11)/2 = 860.555 ft

Width2 = (1000 - 721.11)/2 = 139.445 ft

If we use Width = 139.445 ft, we will find Length = 1721.11 ft

If we use Width = 860.555 ft, we will find Length = 278.89 ft

Both pairs of dimensions are valid answers, as they would use 2000 feet of gate and the area of the school would be 240,000 ft2

4. Find the volume of the square pyramid shown. Round to the nearest tenth if necessary.
Pepsi [2]
**The missing image is attached below**

The correct answer is: 400 ft^3

Explanation:
The volume of the square pyramid = \frac{a^2h }{3}

Where a = base  = 10 ft
h = \sqrt{x^2 - ( \frac{a}{2} )^2} =  \sqrt{13^2 - 5^2} =   \sqrt{144} = 12

Plug in the values in the equation:
The volume of the square pyramid = \frac{10^212 }{3} = 400 ft^3
