Question

The size of three plant cells are given below in scientific notation:

Cell A=4.2 x 10-4
Cell B=21 x 10-5
Cell C=8.4 x 10-4
How many times larger is Cell C than Cell A?

Answer 1

Cell C is 2 times larger than Cell A when comparing their sizes given in scientific notation.

Step-by-step explanation:

To determine how many times larger Cell C is than Cell A, we compare the sizes of the two cells provided in scientific notation:

• Cell A = 4.2 x 10-4
• Cell C = 8.4 x 10-4

To find out how many times larger Cell C is, we simply divide the size of Cell C by the size of Cell A:

Cell C / Cell A = (8.4 x 10-4) / (4.2 x 10-4)

Because the powers of 10 are the same for both Cell A and Cell C, we can directly divide 8.4 by 4.2, giving us:

2 x 100 (since any number raised to the power of 0 is 1)

Therefore, Cell C is 2 times larger than Cell A.
