Answer:

B

Step-by-step explanation:

To multiply scientific notation, multiply each part of the number.

(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12

Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.

The solution is B.

nekit [7.7K]

Answer:


Step-by-step explanation:

We have given that the shape of clementine is sphere .

It has diameter of  3.5 inches .

Radius is half of the diameter .

                    Diameter                   3.5

Radius   =  --------------------  =   ---------------  inches

                         2                              2

                                          4

<h3>Volume of sphere   = -----------   pi r³</h3>

                                          3

Plug the value of  ' r ' and ' pi 'in this formula , we get  

                              4             22            3.5           3.5            3.5

Volume , V  =     --------  *   -------- *   (   --------)  * ( ------- )  * (-------- )

                              3              7               2                2               2

                          22

where  pi  =   ----------  .

                            7

                            3773

Volume  , V  =    -----------  =  22.4583 cubic inches .

                              168


Round to nearest hundredth , we get  Volume of the fruit as 22.45 cubic inches .

Round 705,499 to the nearest thousand.​
makvit [3.9K]

Answer:

705,000

Step-by-step explanation:

To round to the nearest thousand, you look at the number to the right of 5. If the number is 5 or higher then you round 5 up. But it is 4 so you keep 5 the same. All of the numbers after 5 are now 0. 705,000
