Suppose you have $28.00 in your bank account and start saving $18.25 every week. Your friend has $161.00 in his account and is w

Mademuasel [1]

28 + 18.25x = 161 -15x (here, x stands for every week this addition or withdrawal happens)

So:
28+18.25x = 161 - 15x
18.25x = 161 - 28 - 15x
18.25x = 133 - 15x
18.25x + 15x = 133
33.25x = 133
x = 133/33.25
x = 4

So, they will have the same balance in 4 weeks.

A molecular biologist measures the mass of cofactor A in an average yeast cell. The mass is 67.55 pg. What is the total mass in

julia-pushkina [17]

At first, pg means picogram

$1pg=10^{-12}g$

A microgram is a unit to measure the mass

$1\mu g=10^{-6}g$

Then from both relation

$1pg=10^{-6}\mu g$

Now we can solve the question

Since the average mass per cell is 67.55 pg

Since the number of cells is 10^5

To find the total mass multiply them

$\begin{gathered} T\mathrm{}m=67.55\times10^5 \\ T\mathrm{}m=6755000pg \end{gathered}$

We need to change it to microgram, then multiply it by 10^-6

$T\mathrm{}m=6755000\times10^{-6}$

Put a decimal point at the end of the number and move it 6 places to the left to get the answer

$T\mathrm{}m=6.755\mu g$
