Stuck on this for a while not sure

Answers

Circumference of 1 table:
C = πd = 140π = 439.82 cm

Each person needs 60 cm, so divide the circumference by 60 to find the number of people who can sit at each table.
439.82/60 = 7.33

So at most 7 people can sit at each table.

7*12 = 84 so the room can only hold 84 people.

Confused, and there's a test tomorrow. "Write (5+ 2yi) (4-3i)- (5-2yi) (4-31) in a a + bi form, where y is a real number"

Answers

Answer:

  12y +16yi

Step-by-step explanation:

The thing about complex numbers is that you can treat them as binomials and use all of the things you know about multiplying and factoring polynomials.

Here, we assume you have ...

  (5 +2yi)(4 -3i) -(5 -2yi)(4 -3i)

The factor (4 -3i) can be factored out, so you have ...

  = ((5 +2yi) -(5 -2yi))(4 -3i)

  = (4yi)(4 -3i)

  = 16yi -12yi²

At this point, the definition of i comes into play, and you replace i² with -1.

  = 12y +16yi

05.01)A scale drawing of a bathroom is shown below: A rectangle is shown. The length of the rectangle is labeled 2 inches. The width of the rectangle is labeled 3.5 inches. The scale is 1 to 20.

What is the area of the actual bathroom in square feet? Round your answer to the nearest whole number.

7 ft2
19 ft2
12 ft2
140 ft2

Answers

The scale of 1 to 20 , means for every 1 inch on the drawing the actual size would be 20 inches.


The length is labeled 2 inches, so the actual length would be 2 *20 = 40 inches.


The width is labeled as 3.5 inches, the actual length would be 3.5 x 20 = 70 inches.


Now convert the inches to feet by dividing each length by 12:


40 inches / 12 = 3.33 feet.

70 inches / 12 = 5.83 feet.


Multiply them together for total area:

3.33 x 5.83 = 19.4 feet^2

Rounded to the nearest whole number = 19ft^2

The area of the actual bathroom in square feet is 19 ft^2

  • The calculation is as follows;

The scale of 1 to 20 reprsent that for every 1 inch on the drawing the actual size  should be 20 inches.

The length is labeled 2 inches,

so the actual length  is

= 2 (20)

= 40 inches.

Now

The width is labeled as 3.5 inches,

So, the actual length

= 3.5 (20)

= 70 inches.

Now convert the inches to feet by dividing each length by 12:

= 40\ inches / 12 = 3.33 feet\n\n= 70\ inches / 12 = 5.83 feet\n\n  

Now Multiply them together for total area:

= 3.33 (5.83)

= 19.4 feet^2
