A map of an island is shown on a half-centimeter grid,
kupik [55]

Answer:

The answer is below

Step-by-step explanation:

A map can either be scaled up or scaled down. If the map is enlarged then it is scaled up and hence represented by n:1, where n > 1. While is the map is reduced, it is scaled down and is represented by 1 : n, where n < 1.

Since one box has a length of 1 cm by 1 cm. The distance between A and B is 4 boxes = 4 cm = 0.04 m

Hence the scale is given as 1:n, where n > 1. n is gotten from:

n = 960 m / 0.04 m = 24000

Therefore the scale is 1 : 24000

P URGENT I've got a timer going on but really need your help to answer this thank you!!
astraxan [27]

Given:

The radius of inner circle = 13 yd.

The width of the shaded region = 8 yd

To find the area of the shaded region.

Now,

The radius of the outer circle = 13+8 yd = 21 yd

Formula

The area of a circle of radius r unit is \pi r^{2} sq unit.

A = A_{1}-A_{2}

where, A = The area of the shaded region

A_{1} = Area of the outer region

A_{2}= Area of the inner region

Now,

A_{1}= \pi (21^{2})

A_{1} = (3.14)(21)(21)

A_{1}= 1384.74 sq yd

And,

A_{2} = \pi (13^{2})

A_{2} = (3.14)(13)(13)

A_{2}= 530.66 sq yd

Therefore,

A = 1384.74-530.66 sq yd

A = 854.08 sq yd

Hence,

The area of the shaded region 854.08 sq yd.

What are the solutions to the equation 0 = x2 – x – 6?
ioda
Factor to this equation out, the easiest way is to solve for the two x values that add up to -1 but when multiplied is equal to -6. It should look like this: (x +- ?)(x +- ?). 
The factored out form is then (x - 3)(x +2), because -3 + 2 = -1 and when multiplied together gives -6. 
x - 3 = 0
x = 3
x + 2 = 0
x = -2
The two solutions are therefore, x = 3 and x = -2. 

Hope it helps
