This is just a matter of multiplying the two fractions you've been given together. You can make things easier for you by doing some reduction of the fraction before you multiply the numbers together.
6/17 * 17/300 = (6 * 17)/(17 * 300)
Since you have a factor of 17 both top and bottom, they cancel each other out, giving
(6 * 17)/(17 * 300) = 6/300
And since the greatest common factor for 6 and 300 is 6, you can divide both top and bottom by 6 giving
6/300 = 1/50
So Pluto as 1/50 of the diameter as Saturn.</span>
<span>half-life means you divide by 2
21.6 / 3.6 = 6 hf (hf = half-life)
then you divide by 2^6
6.02 x 10^23 / 2^6 = 9.40625 x 10^21 atoms
--------------
26
3hf ===> 2^3
10.0 / 2^3 = 1.25 gram (remaining)
answer : 10 - 1.25 = 8.75g
-------
27
128 / 2^n = 2
64 = 2^n
n = 6
24 /6 = 4
4 days is the half-live of the sample
-----------
28
2.5/4.46 of 50% initial mass
(2.5/4.46) x 0.5 x 2 = 0.5605 g
answer: 2 - 0.5605 = 1.4395 g
----------
29
2^7 = 128
so 7 half-lifes
7* 8040 = 56200 days
----------
30
the time of 10 half-lifes
= 10 x 0.334s = 3.34s </span><span>

Answer:
x=5
Step-by-step explanation:
set up the equation like this: JK+KL=JL
(15)+(10)=(5x)
calculate to find x!
x=5
The answer is 11/3. Multiply the denominator (3) by the whole number (3), add the numerator (2), then <em /><em><u /></em><u>keep the denominator the same</u>! You should end up with 11/3.
