Here is the solution...
Compensation
The compensation is nothing but the process of reforming the given expression to find the answer mentally.
Here we need to rewrite the given expression in order find the answer mentally.
<u>Step 1:</u>
Here we can add 8 with 6572, so we get 6580.
<u>Step 2: </u>
Add 8 from 239, so we get 247.
<u>Step 3:</u>
We can rewrite 247 as 240 + 7
<u>Step 4:</u>
Now we can subtract 240 from 6580, so we get 6340.
We can calculate this mentally.
<u>Step 5:</u>
Finally, we can subtract 7 from 6340 mentally, So we get
6333.
Mathematically, the above expression written as
6572- 239
= 6572 + 8 - (239 + 8)
= 6580 - 247
= 6580 - (240 + 7)
= 6580 -240 - 7
= 6340 - 7
= 6333
Step-by-step explanation:
Assuming the speed of car B to be x and the speed of car A to be x+20
<u>1</u><u>5</u><u>6</u> = <u>2</u><u>0</u><u>8</u>
x. x+20
156(x+20)= 208x
156x+3120=208x
3120=208x-156x
3120=52x
x=60
The speed of car A is (x)= 60
The speed of car B is(x+20)= 80
Answer:hey mate,
To find x u will have to equate it to 360
90+56+68+2x=360
214+2x=360
2x=146
x=73
Hope this helps you...

The mean price and median price are close together.
Answer: Option 2
<u>Explanation:</u>
The shape of the graph which is shown in the picture is symmetric. Since it is symmetrical in shape, most of the data is clustered together around the center. This center is the median. The mean will be close to the median, since most of the data values are close to this.
The graph shows that the prices of the beverages are some where near and close to each other. The prices are not at extreme ends and this makes the shape of the graph symmetrical. Had there been any kind of extreme ends, then the shape of the graph would not have been the same.
The difference between the 2 times would be .055 seconds...
