Answer: 81.33 square units


Step-by-step explanation:

Given sides of triangle = 12,14 and 16 are the a,b and c respectively.

Thus the perimeter of triangle =a+b+c=12+14+16=42

The semi perimeter of triangle s=\frac{42}{2}=21

By Heron's formula

Area of triangle = \sqrt{s(s-a)(s-b)(s-c)}

=\sqrt{21(21-12)(21-14)(21-16)}\\\\=\sqrt{21(9)(7)(5)}\\\\=\sqrt{6615}\\=81.3326\approx81.33\text{ square units}

The area of triangle =81.33 square units.

A roulette wheel has the numbers 1 through 36, 0, and 00. A bet on five numbers pays 6 to 1 (that is, if one of the five numbers
tatiyna

Answer:

5 cents

Step-by-step explanation:

So the roulette wheel would have a total of 38 numbers, which means 38 different possible cases. Since you are allowed to bet on 5 numbers, the chance to win this is 5 out of 38 and to lose this is 33 out of 38.

If you win, you get 1 + 6 = 7 dollar, and if you lose, you lose 1 dollar.

Therefore the expected amount out of this game is:

E = 7\frac{5}{38} - 1\frac{33}{38} = \frac{35}{38} - \frac{33}{38} = \frac{2}{38} = \frac{1}{19} = \$0.0526

or 5 cents

The area of a rectangle is 42 square inches and one side is 12 inches long find the perimeter of the rectangle show your work
uranmaximum [27]
So first of all we need to know that area is length times width
Area = L x W 
since we know the area is 42 and the length is 12 lets plug those in
42 = 12 x W 
now we dont know what W is yet but we can figure it out by dividing 42 by 12
42/12 = 3.5 
So W = 3.5!
but its asking for the perimeter and we know that perimeter is all of the sides of the rectangle added up. Heres a picture
   
       ___3.5___
      |                 |
      |                 |
 12 |                 |  12 
      |                 |
      ************
             3.5

see now we just add those all up together:)

12 + 12 + 3.5 + 3.5 = 31!!
so our perimeter is 31 inches:)
have a good one
