Answer:

Surface area is 300 in Squared

Step-by-step explanation:

2(lw + wh + hl) = rectangular Prism Formula

Length- 12

Width- 9

Height- 2

So just Substitute the values.

2( 12 x 9+ 9 x2 + 12 x 2) = ?

2(108 +18+ 24)

2 x 150

= 300

If you spin the spinner 96 times, what is the best prediction possible for the number of times it will land on yellow or red? Bl
algol [13]
Probability of it turning out the way you want =

         (number of different outcomes that you like)
divided by
         (total number of ways it can possibly turn out) .

Total number of ways the spinner can land = (1 + 4 + 6 + 1) = 12
Number of ways you'll be happy with = (yellow + red) = (6 + 4) = 10

Probability of a spin that you like =    10/12  =  5/6  =  (83 and 1/3) % .

If the spinner is honest, well-balanced, and doesn't stick or scrape,
and nobody blows or sits on it while it's spinning, then you'll predict
that  5/6  of the spins will turn out in ways that you like.

         5/6  of  96  =  80 spins .

What is the area of the rectangle shown on the coordinate plane?
PolarNik [594]

The area of the rectangle is 42 units

The formula for calculating the area of a rectangle is expressed as:

  • A = length * width

From the figure, we will use the formula for calculating the distance between two points as shown:

For the length, we will use the coordinate points (5, 2) and  (2, -1)

Length  = √(-1-2)² + (2-5)²

Length = √9 + 9

Length = √18 = 3√2

Similarly for the width, we will use the coordinate points (5, 2) and  (12, -5)

Width  = √(-5-2)² + (12-5)²

Length = √49 + 49

Length = √98 = 7√2

Area of the rectangle = 3√2 * 7√2

Area of the rectangle = 42 units

Hence the area of the rectangle is 42 units
