RideAnS [48]

Answer:

2.16 \times  {10}^{ - 4}

Step-by-step explanation:

The lab technician is dividing a cell that has a diameter of

4 .32 \times  {10}^{ - 4}

The new cells has a diameter that is half of the diameter of the original cell.

The diameter of the new cell is given as:

\frac{4.32 \times  {10}^{ - 4} }{2}

Rewrite the numerator in standard notation:

\frac{0.000432}{2}

= 0.00216

We rewrite in scientific notation to obtain:

2.16 \times  {10}^{ - 4}

PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Bond [772]

Answer:

R = \frac {3ST}{2S + T}

Step-by-step explanation:

Given the equation;

\frac {3}{R} - \frac {1}{S} = \frac {2}{T}

Rearranging the equation, we have;

\frac {3}{R} = \frac {2}{T} + \frac {1}{S}

Lowest common multiple (LCM) of S and T is ST.

\frac {3}{R} = \frac {2S + T}{ST}

Cross-multiplying, we have;

3ST = R(2S + T)

Making R, the subject of formula;

R = \frac {3ST}{2S + T}

A recipe for cake needs 3/4 if a cup of milk. you are making 1/2 of the recipe.his much milk do you need
r-ruslan [8.4K]
I would say it's 3/8 of a cup because if you multiply 3/4 by 2 it would be 6/8. It's the same amount but just a different measurement. Now just take 3 away from 6/8 and you have 3/8 which is half of 3/4.
