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

50 POINTS!!! <br> Which function is shown on the graph below?<br> See photo
Volgvan

Answer:

C. y=\sqrt{2x-6}+1

Step-by-step explanation:

From the graph of the function, we can see that the domain of the function is x\ge 3, the range of the function is y\ge 1.

Consider the parent function y=\sqrt{x}.

The domain of this function is x\ge 0, the range of this function is y\ge 0.

The function y=\sqrt{2x-6}+1 has

the domain

2x-6\ge 0\\ \\2x\ge 6\\ \\x\ge 3

and the range

y\ge 0+1\\ \\y\ge 1

All other options have different domain, or the range, or both the domain and the range.
