.:|:. Answer .:|:.

9 7/9

.:|:. Evidence | Reasoning .:|:.

When finding the area of a figure, you need to multiply. The area has sides of 4 4/9 and 2 1/5. We can multiply these fractions to find the area.

[] Step 1: Convert the mixed fraction to an improper fraction (An improper fraction is when the numerator is bigger than the denominator). []


4 4/9 = 40/9

2 1/5 = 11/5


[] Step 2: Multiply across []


40 * 11 = 440

9 * 5 = 45


= 440 / 45


[] Step 3: Turn the improper fraction into a mixed number (In other words, simplify). []

440 / 45 = 9 7/9

2-31 The following grade-point averages apply to a random sample of graduating seniors. 3.812.732.513.093.28 3.512.861.203.133.2
Dmitry_Shevchenko [17]

Answer:

The sample range is 2.61.

Step-by-step explanation:

We are given the following grade-point averages which apply to a random sample of graduating seniors below;

3.81, 2.73, 2.51, 3.09, 3.28, 3.51, 2.86, 1.20, 3.13, and 3.24.

As we know that the range of the data is calculated bu using the following formula;

               Range = Highest value in the data - Lowest value in the data

Here, Highest value = 3.81

          Lowest value = 1.20

So, the sample data range = 3.81 - 1.20

                                              = 2.61.

What is the missing polynomial?
german

Answer:

C. 40-4x-12x^2

Step-by-step explanation:

very simple

? – (20 – 4x – 5x2) = 20 – 7x2, so ?  = 20 – 7x2 + (20 – 4x – 5x2)

?  = 20 – 7x2 + (20 – 4x – 5x2)=20-7x²+20-4x-5x²=40-12x²-4x

The storage box for a flag is in the shape of a triangular prism. What is the surface area of the box?
BARSIC [14]

*see attachment for the diagram of the triangular prism box

Answer:

528.8 in.²

Step-by-step explanation:

Surface area of triangular prism = 2(BA) + P*H

Area of triangular base (BA) = ½*b*h

b = 24.5 in.

h = 12 in.

BA = ½*24.5*12 = 147 in.²

Perimeter of triangular base = 24.5 + 17.1 + 17.1 = 58.7 in.

Height of prism = 4 in.

Plug in the values into the surface area formula:

Surface area of prism = 2(147) + 58.7*4

= 294 + 234.8

= 528.8 in.²
