The answer to this is D.

The tricky part of this question is to determine the relationship between Lee's points and Alex's points.

From the description "Lee scored 25 points" we can be sure that Lee's points are 25. That's the easy part.

Here comes the real question. We need to change "that was 3 more than twice the number of points Alex scored" into an algebraic equation. From "twice the number of points Alex scored", we can know it's 2a, as Alex's points are represented by a and twice means 2 times. From "that's 3 more", we can determine that Lee has a higher point (25 larger than 2a by 3 points). So, Alex need to add a few more points in order to have the same value as Lee did.

Therefore, if we combine everything together, we can get 25 (Lee's points) = 3 + 2a (twice Alex's points plus 3 because Alex has less points). The answer is D.

A hemisphere fake stone made of clay has a diameter of 16 inches. The density of clay is 0.0035 pounds per cubic inch. The clay

Rufina [12.5K]

Answer:

$137.82

Step-by-step explanation:

The volume of a hemisphere stone is given by the volume of a half-sphere:

Volume = (2/3) * pi * radius^3

If the diameter is 16 inches, the radius is 16/2 = 8 inches, so the volume is:

Volume = (2/3) * pi * 8^3 = 1072.33 in3

We need a total of 8 stones, so the total volume is:

Total Volume = 8 * 1072.33 = 8578.64 in3

The density of clay is 0.0035 pounds per cubic inch, so the total weight of the 8 stones is:

Weight = Total Volume * density = 8578.63 * 0.0035 = 30.0252 pounds

Finally, if the price of each pound of clay if $4,59, the final price is:

Price = 30.0252 * 4.59 = $137.82

Now suppose there are more goods and services and the economy is now open to trade with other countries. Based on this generated

OLEGan [10]

It should be noted that GDP deflator simply measures the changes in price for goods and services.

Your information is incomplete as the figures aren't given. Therefore, an overview will be given.

Gross domestic product simply means the total monetary value of the finished goods and services that are produced in a country.

The formula for calculating the GDP deflator will be:

= Nominal GDP/Real GDP × 100

Also, the formula fro calculating real GDP per capita will be:

= Real GDP/Total population

In conclusion, the real GDP is the GDP of a country that has been adjusted for inflation.

how many different combinations of six people can sit in four chairs? assume one person sits in each chair

Tems11 [23]

We want to choose 4 people and we have 6 people to choose from. This is a combination of 6, 4 by 4. Also called <em>six choose four</em>.

The following formula:

$_rC_n=\frac{n!}{r!(n-r)!}$

Is the combination of $r$ objects choosen from a total of $n$ . It's $n$ choose $r$ .

For our problem, we just need to compute the following:

$_4C_6=\frac{6!}{4!(6-4)!}=\frac{6\times5\times4!}{4!2!} =\frac{6\times5}{2\times1} =15$

Thus

$\boxed{_4C_6=15}$

Therefore the answer is 15 different combinations
