Uranium-235 has a half-life of 700 million years. How many years will it take Uranium-235 to decay to 1/8 of its original mass?

Answer: 2.1 billion years

Explanation:

The half-life of an element refers to the amount of time it would take for half of its mass to decay.

In 700 million years, Uranium - 235 will be 1/2 of its original mass.

If divided by 2, the 1/2 becomes 1/4 which is the proportion of the original mass the Uranium would get to after another 700 million years.

Dividing by another would get the Uranium-235 to 1/8 of its original value and would take another 700 million years.

Total time taken:

= 700 + 700 + 700

= 2,100 million years

= 2.1 billion years

John gets a weekly allowance of $20 from his parents. The only thing he has a real interest in buying is a big slice of pizza af
IRISSAK [1]

From the above table we can see the MU from consumption of 6th spice is zero. Therefore, John will consume 5 slices of Pizza.

<h3> If John purchased 8 slices, what total utility would he enjoy?</h3>

When he consumes 8 slices of Pizza then the total utility that he will derive will be:

TU = 20 + 12 + 10 + 6 + 2 + 0- 2 - 6

= 42 utils.

<h3>What is the complete table that shows the marginal utility per dollar for each slice of pizza and each funnel cake?</h3>

See the attached table I in the attached.

<h3>Assuming John’s parents do not allow him to use any savings, what is his optimal consumption bundle of pizza and funnel cakes? </h3>

When John expends all of his income and cannot use his savings, he will maximize his overall utility.

Then he will maximize his TU when the MU/$ of the two commodities are equal. According to the preceding data, the MU/$ is equivalent for the following combinations. See table II in the attached.

From the chart above, we can see that he can spend up to $ 20 if he consumes three pieces of pizza and four funnel cakes.

However, because he cannot spend his funds, he will have fewer than three slices and four funnel cakes.

As a result, he will give up 1 slice of pizza because the third slice provides him a MU of 10 utils and the fourth piece of Funnel cake gives him a MU of 20 utils.

The optimal consumption basket contains two pieces of pizza and four funnel cakes.

<h3>At John’s optimal consumption bundle, what total utility will he gain?</h3>

Total Utility is given as:

(20+12)+(50+40+32+20)

= 32 + 142

= 174 utils.

stich3 [128]
One key similarity would be that they all started off as colonial powers ruled by larger power in Europe. Most of these nations gained independence through revolution as well, while a smaller amount gained it by the European state giving the colony independence (canada, Jamaica), Cuba was also technically both (revolution against spanish to be ruled by America, given Independence by America). A big difference is that most of North america was ruled by the British and the French, while South and Central America were settled predominantly by the Spanish and Portuguese. This resulted in huge differences in culture, including language (English/french vs Spanish/Portuguese) and religion (Protestantism vs Catholicism).
