The half price of helium-5 is 7.6 X 10 to the power of negative 22 seconds and the half-life helium -9 is 7 x 10 to the power of
Digiron [165]

Answer:

Approximately 9.211 times

Step-by-step explanation:

Given

x = 7.6 * 10^{-22}s --- half life of helium-5

y = 7 * 10^{-21}s --- half life of helium-9

Required

How many times greater is y than x

To do this, we simply divide y by x

\frac{y}{x} = \frac{7 * 10^{-21}s}{7.6 * 10^{-22}s}

\frac{y}{x} = \frac{7 * 10^{-21}}{7.6 * 10^{-22}}

Apply law of indices

\frac{y}{x} = \frac{7 * 10^{-21--22}}{7.6}

\frac{y}{x} = \frac{7 * 10^{-21+22}}{7.6}

\frac{y}{x} = \frac{7 * 10}{7.6}

\frac{y}{x} = \frac{70}{7.6}

\frac{y}{x} = 9.211

natulia [17]

Answer:

4.1 shirts

Step-by-step explanation:

Mean can be found by adding all data points and dividing that by the total amount of data points.

There are 12 students selling shirt, which gives you 12 data points.

So (3+4+8+5+2+5+0+5+3+4+3+7)/12 = 4.083...

Which rounds to 4.1 shirts

If sarah is 24 years younger than her mother and if the sum of their age is 68 how old is sarah
UkoKoshka [18]
The sum of two numbers if just the numbers added together, so you would just need to do some simple algebra.

The ages added together are 68, and the opposite of addition is subtraction!

(total age) - (sarahs age) = (mothers age)
68 - 24 = 44

44 should be her mothers age!


(If you were trying to calculate the sum of their ages, you would just add them together, and 24 + 44 = 68)
