Answer: 24 hours

Step-by-step explanation: If it took 12 men 12 hours to construct a wall, then it would take 6 men longer.

If 12 divided by 12 is one, that means each man took one hour to work.

If 12 divided by 6 is two, that means each man takes two hours to work.

6 times 2 is 12, and 12 times 2 is 24. It takes 24 hours to complete the wall.

You multiply 6 times 2 because each man works 2 hours, so 12 equals the number of hours all the men worked in total.

You do 12 times 2 because if each men works 2 hours and there are 6 men, they work a total of 12 hours. You do 12 times 2 because it is going to take the men double the amount of time to complete the wall because 6 is half of 12.

Answer: D

Step-by-step explanation:

The key to finding the line perpendicular to the one given is teh slope. The slope is the opposite reciprocal of the original line.

m=3

perpendicular m=-1/3

Now that we know the slope, we can see which of our answer choices have -1/3 as the slope. We can see D is the only option that has -1/3 for slope.

23 cm
Alenkasestr [34]

Answer:

445.2 square cm

Step-by-step explanation:

The surface area consists of  area of two bases and area of three leteral faces. Each lateral face is a rectangle with length of 23 cm and width of 6 cm.

The area of rectangle is

A_{rectangle}=\text{length}\times\text{width}

So,

A_{rectangle}=23\times 6=138\ cm^2

The area of base is given as 15.6\ cm^2

Thus, the surface area is

SA=2A_{base}+3A_{lateral\ face}\\ \\SA=2\cdot 15.6+3\cdot 138=445.2\ cm^2

Can anyone help me with # 18
malfutka [58]
The answer is between Day 3 and Day 4. If you look at the slope of the line between Day 3 and Day 4, you can see that it's horizontal, whereas the other slopes are very steep. Therefore, the answer is between Day 3 and Day 4.
