6,500 is 6.5 x 10 to the third power not 6.5X10 to the second
mr Goodwill [35]2 years ago

Answer:

6,500 = 6.5 × 10² is not written correctly.

Step-by-step explanation:

In the scientific notation we write a very large or very small number in easy notation of the product of a number between 0 to 9 and exponent of 10,

For this,

If we move decimal to the left side then the exponent of 10 is positive number of shifting,

While, if we move decimal to the right side then the exponent of 10 is negative number of shifting,

By the above explanation,

1207000=1.207\times 10^6

6500=6.5\times 10^3

901=9.01\times 10^2

402000=4.02\times 10^4

Answer:

The % increase is 7.179 but see the remark I made below. What I have given and what it could be is a rounding error. Less than 2 dollars error is not much when you are calculating something for someone just to show them how to do it.

Step-by-step explanation:

242,555 * x/100 = 259,970           Multiply by 100

242,555 * x = 259970 * 100

242,555 * x = 25997000            Divide by 242555

x = 24997000/242444

x = 107.179

That's the total increase.

What you want is 7.179%

If you take 7.179% of 242,555 and add it onto 242555 you should get 259,970

7.1797/100 * 242555 = 17413.02

17413.02 + 242555 = 259968.02

Why isn't it exact. I'm out just about 2 whole dollars. The reason is that the % isn't exact. It's only out to 3 decimal places which apparently is not enough. You can go over my numbers if you want more exactness us use something that is rounded to 7.180 if you like.

I need help in area it's hard
Fofino [41]
The area is the length times the width. Find area of shapes by counting unit squares. Some shapes will require combining partial square units to find area.<span>  

        For example - </span><span>A rectangle is 5 centimeters long and 4 centimeters wide. What is its area? </span>

Area = Length * width  

The length is <span><span>5</span></span> centimeters. The width is <span><span>4</span></span> centimeters. So the area is <span><span>5 times </span>4</span> square centimeters.

= 20 square centimeters
