George saves 18% of his total gross weekly earnings from his two part-time jobs he earns $6.25 per hour from one part time job and $7.50 per hour from another part-time job george works a total of 40 hours between the two jobs each week what additional information is needed to determine the amount of earnings he saves each week

his weekly earnings

Explanation:

He earns $(6.25 + 7.50) = $13.5 between the two jobs per hour

$13.5 = 1 hr

$x = 40hr

Cross multiply and make $x the subject,

x = $540 in 40 hours.

If he makes $540 in 40 hours,

18% of $540 =

18/100 = x/540

× = $97.2

George saves $97.2 from the two jobs weekly.

higher potential

explanation:

because it is in a high speed so it must move into a of high potential

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
