Explain how to compare decimals. Use the numbers 6.75 and 6.732 to help you explain this process.

tysm I am struggling

Answers

Answer:

6.75>6.732  

Step-by-step explanation:

We are given that  

6.75 and 6.732  

We have to compare two given decimal numbers.  

First we convert like decimal number  

In 6.75 there are two digits after decimal point.  

In 6.732 , there are three digits after decimal point  

Therefore, we put zero in 6.75 to convert like decimal number

Now, we get  

6.750  

Unit place of both decimal numbers are same and tenth place of both decimal number are same.  

Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3  

5 >3

Therefore, 6.750 is greater than 6.732  

6.75>6.732

to compare these decimals, we first have to turn 6.75 into 6.750, so it has the same place value as 6.732. adding a 0 to the right side of the last digit in the decimal does not change its value. now, we compare them. 6=6, 7=7, 5≠3. since 5 is greater than 3, we know 6.75 is greater than 6.732. this can be written as 6.75>6.732.

Mr. Samuuel Salesman is paid $125 a month. He also earns $50 for every vacuum he sells.

I need to find an equation, a table, and a graph

Answers

…………..Y=125+ 50x…………

Answer:

earnings = $125 + ($50/vacuum)x

Step-by-step explanation:

This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:

The equation represents the man's total earnings.  The independent variable is x, the number of vacuums he sells.

Thus, earnings = $125 + ($50/vacuum)x.  As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).

Plot a black dot at (0, $125).  Now move 2 units to the right from this dot and from there up by $100 to (2, $225).  Plot this new point.  Then draw a line through the two points you've plotted.

Table:

 x   earnings

----  --------------

 0      $125

  1       $125 + $50 = $175

  2      $125 + $100 = $225

and so on.

A TV has an original price of $499. Find the new price given a 10% increase.

Answers

The new price given is $648.7
Have a great day/night

Answer: $548.9

Step-by-step explanation:

To find the next price you have to find 10% of the original price then add it. You can find the increase by dividing 499 by 10 to get 10%.

499 divided by 10 = 49.9

Now add the increase to the original price for your answer!

499 + 49.9 = $548.9

Which measure do you think would be the most helpful for her and why? ​

Answers

Answer:

Step-by-step explanation:

Firstly for the the mean you add all the numbers and divide by how many they are.73+88+85+88+99+134+129 and divide it by 7 .

Secondly for the median arrange the numbers numerical form and pick the middle number.

Mode is finding the most common number.

Range subtract the largest number from the smallest number.the best measure is mean because it shows you all you bought and helps in finding the perfect amount
