A track is 200 meters long. How many times must Julius run around the track to run 3 kilometers ?

1 answer:

4 0

Here is how you would do this: If there are 1000 meters in one kilometer, and you know that this track is 200 meters long, then you can find how many times Julius must run around the track in order to reach ONE kilometer:

1000 meters / 200 meters = 5 times in around the track for ONE kilometer.

To find how many times Julius would need to run around to reach THREE kilometers you simply do the following:

5 x 3 = 15 ---> Julius would need to run around the track 15 times in order to reach 3 kilometers.

Answer:

V = 205 in^3 to the nearest whole number

Step-by-step explanation:

V = 4/3 π r^3

Plugging in the given information:

V = 4/3 * 3.14 * 7^2

V = 205.147.

A fossilized leaf contains 18% of its normal amount of carbon 14. How old is the fossil (to the nearest year)? Use 5600 years as

Sati [7]

Answer: The age of the fossilized leaf is 13829 years.

Step-by-step explanation:

Expression for rate law for first order kinetics is given by:

$t=\frac{2.303}{k}\log\frac{a}{a-x}$

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant = 100

a - x = amount left after decay process = $\frac{18}{100}\times 100=18$

a) for completion of half life:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

$t_{\frac{1}{2}}=\frac{0.693}{k}$

$k=\frac{0.693}{5600years}=0.00012years^{-1}$

b) for finding the age

$t=\frac{2.303}{0.00012}\log\frac{100}{18}$

$t=13829years$

The age of the fossilized leaf is 13829 years.

What's the slop of this line?

Tatiana [17]

Slope is rise over run. It goes up 1 unit for every unit it goes over, so the slope would be 1/1, or just 1.
