Answer:

9y+3

Step-by-step explanation:

you add all the common numbers and you end up with:

9y^6+3+y^-5

then you put the y^-5 under the other numbers and make it positive so it becomes:

9y^6+3/y^5, then you subtract the exponents of y: 6-5, so that cancels out the y on the bottom making it:

9y+3

Josue broke a cell sample into 12 batches, each weighing 6.9 x 10 ^-10

Klio2033 [76]

Using proportions, it is found that the original sample weighed $8.28 \times 10^{-9}$ grams.

This question is solved by <em>proportions</em>, using a rule of three.

The weight of 1 batch, in grams, is of $6.9 \times 10^{-10}$ . How much do the sample of 12 batches weigh?

The rule of three is:

1 batch - $6.9 \times 10^{-10}$ grams.

12 batches - x grams

Applying cross multiplication:

$x = 12 \times 6.9 \times 10^{-10} = 82.8 \times 10^{-10}$

Applying scientific notation:

$8.28 \times 10^{-9}$

The original sample weighed $8.28 \times 10^{-9}$ grams.
