Answers

Answer:

5pm

........................

Mr. Lim has to make calls at 5:00  pm if he wants to talk with his client at 7:00 AM in Chicago due to the different time zone.

What are Time Zones?

A time zone is any place that observes the same standard time. For current time zones around the world, see the interactive Time Zone Map.

Given, Mr. Lim, who is in Singapore, wants to make a phone call to his client in Chicago. The local time in Chicago is 14 h behind the local time in Singapore. If Mr. Lim wants to call his client at 7 a.m. (Chicago local time)

Since there is a time difference between the two countries. Mr. Lim has to make calls 14 hours before as per the local time zone

14 hours before 7 AM is 5: 00 PM.

Therefore, Due to the time difference, Mr. Lim must make calls at 5:00 p.m. if he wishes to speak with his client at 7:00 a.m. in Chicago.

2x+5y=6
−x+2y=−3

Answers

Answer

$3

Step-by-step explanation:

To find the x value, you want to cancel out the y terms in the equations. To do so, multiply (2x+5y=6) by 2, and (-x+2y=-3) by -5. This gives you

4x+10y=12

5x-10y=15

You can then cancel out the y terms and add the other terms from the 2 equations together to make

9x=27

You then divide 27 by 9 to get 3 as the value for x.

  h = 7 in

  LA = 42π in²

  SA = 60π in²

Step-by-step explanation:

Use the appropriate formula with the numbers you know, and solve for the number you need to know.

  V = πr²h

  h = V/(πr²) = (63π in³)/(π(3 in)²)

  h = 7 in

__

  LA = 2πrh

  LA = 2π(3 in)(7 in)

  LA = 42π in²

__

  SA = 2πr(r +h)

  SA = 2π(3 in)(3 in +7 in)

  SA = 60π in²

Explain what median is and how to solve for it

Answers

The median is the middle value in the list of numbers. to find the median list your numbers from smallest to largest and find the middle!

Answer: See below

Step-by-step explanation:

Median is the value that separates the higher data and lower data. In simple terms, it is the "middle" value of the whole set of data. There are two different ways to solve for the median.

1. If the data set has an odd number of values, line the values up in increasing order. Then the value or number that lies in the middle will be the median.

For example, if we are given a data set {1, 3, 4, 2, 5}. First, we line them up by increasing order, which becomes {1, 2, 3, 4, 5}. Since it is an odd number set, we can directly get the median which is 3.

2. If the data set has an even number of values, line the values up in increasing order. Then there will be two number that lies in the "middle" together. We add them up and divide them by 2. The average of the two numbers will be the median of the set.

For example, if we are given a data set {2, 6, 4, 10, 8, 12}. First, we line them up by increasing order, which becomes {2, 4, 6, 8, 10, 12}. Since it is an even number set, we get our median from the two numbers in the middle, which are {6, 8}. We add them together to get 14 and then divide by 2 which is 7. So the median will be 7.

Hope this helps!! :)
