Answer:

\boxed{\text{672 mi}^{2}}

Step-by-step explanation:

The formula for the surface area of a rectangular prism is

S = 2(lw + lh + wh)

Data:  

 l = 12 mi

w = 12 mi

h =   8 mi

Calculations:

2(Top + Bottom) = 2lw  = 2 × 12 × 12 = 288 mi²

2(Front + Back) = 2lh   = 2 × 12 ×   8 = 192 mi²

  2(Left + Right) = 2wh = 2 × 12 ×   8 = <u>192 mi² </u>

                                         Total area = 672 mi²

The surface area of the rectangular prism is \boxed{\textbf{672 mi}^{2}}

Select the correct scientific notation form of this numeral.
ioda

The scientific notation for the number 1063 is 1.063×10³ after using the concept of fraction option (B) 1.063×10³ is correct.

<h3>What is the number?</h3>

A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

It is given that:

The number is 1063

As we know the scientific notation can be written as:

\rm = A\times10^a

1063 can be written as:

= 1063  

= (1063/1000)1000

1.063×10³

Thus, the scientific notation for the number 1063 is 1.063×10³ after using the concept of fraction option (B) 1.063×10³ is correct.

The logo for Chris's Calculator Company is 3 semicircles. The logo will be placed on the company building and will be 4 feet tal
Keith_Richards [23]

Answer:

The area of the logo is 18.84\ ft^{2}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of a semicircle is equal to

A=\frac{1}{2}\pi r^{2}

so

The area of the logo is equal to multiply by 3 the area of one semicircle

A=\frac{3}{2}\pi r^{2}

we have

r=4/2=2\ ft -----> the radius is half the diameter

substitute

A=\frac{3}{2}(3.14)(2)^{2}=18.84\ ft^{2}

Find the IQR (interquartile range).<br> 19, 21, 18, 17, 18, 22,46
yanalaym [24]

Answer:

4.

Step-by-step explanation:

Step 1: <u>Formula.</u>

IQR=Q3-Q1

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 2: <u>Explain/define.</u>

  • The interquartile range is the difference between quartile 3 and quartile 1.
  • Quartile 1 is the median of the upper half of a data set.
  • Quartile 3 is the median of the lower half of a data set.
  • The median is the 'middle value.'

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 3: <u>Order/arrange.</u>

In order to find the median, you must first put the numbers in numerical order.

19, 21, 18, 17, 18, 22, 46

               ↓

17, 18, 18, 19, 21, 22, 46

The lower half of the data set, not including the median of the whole data set, is 17, 18, and 18.

The upper half of the data set is 21, 22, and 46.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 4: <u>Solve.</u>

  • 17, 18, 18
  • 21, 22, 36

Next, we find the medians of both sets.

The median of the lower half is 18 (Q1).

The median of the upper half is 22 (Q3).

Lastly, we subtract Q3 from Q1.

22-18=4.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 5: <u>Conclude.</u>

I, therefore, believe the interquartile range of this data set is 4.
