Write an expression where you multiply a decimal number by 100. In a complete sentence, describe which direction and how many pl

Tatiana [17]

If you are multiplying by 100, the decimal will move 2 places to the right.

It moves to the right when multiplying because the number is getting greater, and there are 2 zeroes in 100 so it moves twice.

Recall that m(t) = (1/2)^t/h for radioactive decay, where h is the half-life. Suppose that a 500g sample of phosphorus-32 decays

katrin2010 [14]

The question is incomplete, here is the complete question:

Recall that m(t) = m.(1/2)^t/h for radioactive decay, where h is the half-life. Suppose that a 500 g sample of phosphorus-32 decays to 356 g over 7 days. Calculate the half life of the sample.

<u>Answer:</u> The half life of the sample of phosphorus-32 is $14.28days^{-1}$

<u>Step-by-step explanation:</u>

The equation used to calculate the half life of the sample is given as:

$m(t)=m_o(1/2)^{t/h}$

where,

m(t) = amount of sample after time 't' = 356 g

$m_o$ = initial amount of the sample = 500 g

t = time period = 7 days

h = half life of the sample = ?

Putting values in above equation, we get:

$356=500\times (\frac{1}{2})^{7/h}\\\\h=14.28days^{-1}$

Hence, the half life of the sample of phosphorus-32 is $14.28days^{-1}$

2x-7=13 what is does x stand for?

andriy [413]

Answer:

x=10

Step-by-step explanation:

2x-7=13

13+7=20

20/2=10

lets see if it works:

2(10)-7-13

20-7=13

it works! which means is 10

please mark me as brainliest!!<3
