I the answer To You Problem Is C
<h2>Hello!</h2>
The answer is:
It will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.
<h2>Why?</h2>
From the statement, we know that on Monday, bricklayers took 3 hours to lay a total of 4200 bricks.
So, we have that the rate of the four bricklayers is given by the following equation:
Therefore, we have that the rate of the four bricklayers is 1400 bricks per hour, meaning that each bricklayer can lay 350 bricks per hour.
Now, to calculate how many hours it will take to the 2 bricklayers to lay a total of 3150, we need to divide the calculated rate (for bricklayers) by two, since there are only 2 bricklayers working on Tuesday.
So, calculating the time, we have:
Hence, we have that it will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.
Have a nice day!
No. This is not random sampling as the students chose are not chosen at random. Random sampling would be something done where each sample has equal probability of being chosen. Clearly this is not random sampling.
Answer:
723.53 m^2
Step-by-step explanation:
The area is the product of the width and length. Each foot is 0.3048 meters, so the area in square meters is ...
(59 ft·0.3048 m/ft)·(132 ft·0.3048 m/ft) ≈ 723.53 m^2
