Tiles (6" by 6") can be installed at the rate of 50 per worker hour. The floor of a large lobby area (80’ by 40’) is to be cover
RideAnS [48]

Answer:

Step-by-step explanation:

Tiles (6" by 6") can be installed at the rate of 50 per worker hour. Since the tile is a square, its area is

L^2 = 6^2 = 36 inches square

So in an hour, a worker installs 50 tiles whose area is 36 inches square. Total square meters installed per hour will be 50 × 36 = 1800 inches square per hour.

If three workers are assigned to this task, their work rate will be

1800 × 3 = 5400 inches square per hour.

The floor of a large lobby area (80’ by 40’) is to be covered with these tiles. We would convert from feet to inches.

1 foot = 12 inches

80 feet = 80 × 12 = 960 inches

40 feet = 40 × 12 = 480 inches

Area of the lobby = 90 × 480 = 460800 inches square.

If the 3 workers install 5400 inches square in 1 hour,

Then then they will install 460800 inches square in

460800/5400 = 85.33 hours

Converting to the nearest whole day, it becomes

85.33/24 = 3.55

Approximately 4 days

Solve the inequality, then identify the graph of the solution.<br> 2x – 1 &gt; x + 2
densk [106]

Answer:

x > 3

Step-by-step explanation:

The first part is to solve the inequality, which is very easy:

2x - 1 > x + 2, so 2x - x > 2 + 1 so

x > 3

Then we have to graph the solution... that's also easy.  It will look like the graph attached, meaning it includes ALL the values X > 3 (that's why the line is dashed on the 3), for ALL the values of Y.

That's a weird graphic, but it does represent the inequality we found.

Find the first, fourth, and eighth terms of the sequence. a(n)=-2 x 2^n-1
leonid [27]

Answer:

2, 16 and 256.

Step-by-step explanation:

Just substitute  for n:-

first term ( when n = 1) =  2 * 2^(1-1)

= 2 * 1 =  2

4th term =  2 * 2^(4-1) =  16

8th term = 2* 2^(8-1) = 256
