A baseball player made six hits in nine innings. What is the ratio of hits to innings?
UNO [17]
A baseball player made six hits in nine innings.

Therefore, his ratio of hits to innings, which means his number of hits relative to the number of innings, is 6:9.

However, this isn't simplified.  To simplify a ratio, we must find the GCF (Greatest Common Factor) of the two terms.

The GCF of 6 and 9 is 3, thus, we divide both of the terms by 3 to get our simplified answer.

6:9 = 6/3 : 9/3 = 2:3

Your answer is that the ratio of hits to innings for the baseball player is 2:3.  (This can also be expressed as 2/3 or 2 to 3.)

Hope this helps! :)

The half life of silicone-32 is 710 years. If 30 grams is present now, how much will be present in 300 years?
Irina18 [472]

Answer:

22.38 g of silicone-32 will be present in 300 years.

Step-by-step explanation:

A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay and its given by

                                           N(t)=N_0(\frac{1}{2})^{\frac{t}{t_{1/2}}

where,

N(t) = quantity of the substance remaining

N_0 = initial quantity of the substance

t = time elapsed

t_{1/2} = half life of the substance

From the information given we know:

  • The initial quantity of silicone-32 is 30 g.
  • The time elapsed is 300 years.
  • The half life of silicone-32 is 710 years.

So, to find the quantity of silicone-32 remaining we apply the above equation

N(t)=30\left(\frac{1}{2}\right)^{\frac{300}{710}}=30\left(\frac{1}{2}\right)^{\frac{30}{71}}\approx22.38 \:g

22.38 g of silicone-32 will be present in 300 years.
