The number of people at the party now is 23.

The percentage of a number is the fraction of that number multiplied by 100. Percentages are represented with this sign: %.

3 friends arrive at a party. The percentage of people increase by 20%.This can be represented with this equation:

p x 20% = 3 people

where p is the number of people at the party before the friends arrived.

p = 3 / 20%

p = 3 / 0.20

p = 15 people

The total number of people at the party now : 15 + 8 = 23.

Answer:

single payment variable annuity

Step-by-step explanation:

Given : ABC Insurance offers an annuity with 4.5% APR for the next 5 years. You decide to invest $1000 each year into this account.

To find : What type of annuity is this?

Solution :

Annuity is the form of insurance in which some of the money is paid each year to secure for future.

There are two types of annuity:

Single payment variable annuity - In this annuity the payment is made at the end of each period  over a fixed length of time. Also in this annuity payments are made monthly, quarterly, semi-annually or annually.

Annuity due - is the opposite of single payment variable annuity as in this the payment is made at the beginning of each period.

In the given situation the annuity is single payment variable annuity because the investment is done each year for 5 years.

Answer:

Answer:

7 1/2 cups

Step-by-step explanation:

First, convert the measure of ice cream from pints to cups:

1 pint = 2 cups

⇒ 4 pints = 4 × 2 = 8 cups

Therefore,

Milkshake = 8 cups of ice cream + 1 1/2 cups of milk

                 = 9 1/2 cups

If he drinks 2 cups of milkshake:

Remaining milkshake = 9 1/2 - 2

                                    = 7 1/2 cups

1pint=2cups

Total cups:-

The total area of cardboard needed is equal to 121.34 square centimeters.

This is equal to the surface of the given chocolate.

First, we will have two sides that are rectangles measuring 16cm by 2.6cm, so the area is:

[tex]A = 16cm*2.6cm = 41.6cm^2[/tex]

Then we have another rectangular side which is the bottom one, that is a rectangle of 2.2cm by 16cm, so the are is:

[tex]A' = 2.2cm*16cm = 35.2cm^2[/tex]

Finally, we have the areas of the two triangular faces, the areas of these are:

[tex]A'' = 2.2cm*3cm/2 = 1.47cm^2[/tex]

Then the total area of cardboard needed is:

[tex]area = 2*A + A' + 2*A'' = 2*41.6cm^2 + 35.2cm^2 + 2* 1.47cm^2 = 121.34 cm^2[/tex]

Step-by-step explanation:

The surface area of circle of radius 3 cm and cube of edge length x cm being equal implies [tex]x = \sqrt{k\pi}[/tex] integer (k = 6).

Suppose that radius of the considered sphere is of 'r' units.

Then, its surface area S would be:

[tex]S = 4\pi r^2 \: \rm unit^2[/tex]

Given that:

Finding the surface area of the considered cube and sphere:

Thus, we get:

[tex]6x^2 = 36\pi\\\\\text{Dividing both the sides by 6}\\\\x^2 = 6\pi\\\\\text{Taking root of both the sides}\\\\x = \sqrt{6\pi} \: \rm cm[/tex]

(took positive value out of the root since x cannot be negative as it represents length of the edge of a cube which cannot be a negative quantity).

Thus, the surface area of circle of radius 3 cm and cube of edge length x cm being equal implies [tex]x = \sqrt{k\pi}[/tex] integer (k = 6).

Using proportions, it is found that the amount owed for each bill are given as follows:

$31.33 for food $9.90 for alcohol.

A proportion is a fraction of a total amount.

In this problem, each of the bills are split equally among the five people, hence the fraction is 1/5.

Thus:

1/5 x 156.65 = $31.33

1/5 x 49.50 = $9.90.

Hence the amount owed for each bill are given as follows:

$31.33 for food $9.90 for alcohol.

Answer:

0** (READ BELOW)

Step-by-step explanation:

First, solve for g(0). Since g(0) = 3x +2, we plug in 0 for x.

So,

g(0) = 3(0) + 2  = 0 + 2 = 2.

Now that we have an answer for g(0), we can plug it into f(x).

So,

f(x) = (x-2)/3

f(x) = f(g(0)) = f(2).

f(2) = (2-2)/3 = 0/3 = 0.

Thus, f(g(0)) = 0.

Essentially, you first solve for g(0) and use the answer from that to solve for f(x) where x is your answer from g(0).

**I was unsure of what the equation was for f(x) based on how you wrote it in the question, but I assumed it was f(x) = (x-2)/3.
