Answer:

208 dollars

Step-by-step explanation:

necklaces- 24 x 5 = 120

bracelets- 8 x 3 = 24

anklets- 16 x 4 = 64

added together- 208

Nina makes a total of $208.

$208 money does she make.

Here, we have,

To calculate how much money Nina makes, we need to determine the total revenue from selling bracelets, necklaces, and anklets.

The revenue from selling bracelets can be calculated by multiplying the number of bracelets sold (8) by the price per bracelet ($3):

Revenue from bracelets = 8 * $3 = $24

The revenue from selling necklaces is found by multiplying the number of necklaces sold (24) by the price per necklace ($5):

Revenue from necklaces = 24 * $5 = $120

The revenue from selling anklets can be calculated by multiplying the number of anklets sold (16) by the price per anklet ($4):

Revenue from anklets = 16 * $4 = $64

To find the total revenue, we sum up the revenue from each type of item:

Total revenue = Revenue from bracelets + Revenue from necklaces + Revenue from anklets

Total revenue = $24 + $120 + $64 = $208

Therefore, Nina makes a total of $208.

Answer:

-write down all the expenses that the family incurs for the month

- categorize the expenses into those that could be avoided and those that are not avoidable (like mortgage payments)

- cut down on the expenses that have been identified as avoidable

- invest a small part of the money saved in something that could help the money increase in value

- translate the monthly budget into a yearly budget to achieve long term goals

Step-by-step explanation:

Budgeting is the process by which revenues and expenses are estimated over a period of time.

Budgets are are usually reviewed occasionally to meet current needs.

The aim of budgeting is to allocate sufficient funds to meet set goals and to reduce waste.

The process of budgeting will involve enumerating expenses, identifying avoidable expense, cutting down avoidable expense, investing funds saved, and translate monthly to yearly budget in order to achieve long term goals.

Answer:

1) write down all the expenses that the family incurs for the month

2) categorize the expenses into those that could be avoided and those that are not avoidable (like mortgage payments)

3) cut down on the expenses that have been identified as avoidable

4) invest a small part of the money saved in something that could help the money increase in value

There are 29 students in the class.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Tasha hands out 5 note cards to each student in the class.

And, She hands out all of the 145 note cards contained in the package.

Answer:

1/3

Step-by-step explanation:

To find equivalent fractions, we can multiply or divide the original fraction by 1, since it won't change the value.

That means, dividing the numerator and denominator by the same integer.

For example, in this case, we divided both the numerator and denominator by 6.

6/6=1

18/6=3

So we divided the entire fraction by 6/6, which doesn't change the value of the fraction, just simplifies it.

Answer: [tex]\frac{1}{3}[/tex]: D

Step-by-step explanation:

This is simple, just simplify the fraction.

[tex]\frac{6}{18}[/tex]

You have to find the greatest common factor. In this case, it is 6 because both of them can be divided by 6.

When you divide 6 by 6, you get 1.

When you divide 18 by 6, you get 3.

Therefore, your answer is [tex]\frac{1}{3}[/tex].

Answer:

Step-by-step explanation:

Joe's Painting: 20x + 100 = y

Steve's Painting: 15x + 120 = y

x = hours worked

y = total income

We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:

20x + 100 = 15x + 120

First, we have to move the 100 by subtracting it from both sides.

20x = 15x + 120 - (100)

20x = 15x + 20

Then, we need to move the 15x by subtracting it from both sides.

20 - (15x) = 20

5x = 20

Lastly, we need to divide 5 from both sides.

5x = 20/5

x = 4

Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.

Answer:

Step-by-step explanation:

No.  y = - (x + 2) + 4 is not even a quadratic.

If you want a quadratic you must indicate squaring:  y = - (x + 2)^2 + 4.

Answer:

i have no clue

Step-by-step explanation:

Answer:

1.a 519.615

1.b 173.21

2. It would take approximately 2.1 minutes

Step-by-step explanation:

If the population triples every hour then after one hour the population must be:

population(0) = 100

population(1) = 100*3 = population(0)*3

After two hours:

population(2) = population(1)*3 = population(0)*3*3 = population(0)*3²

After three hours:

population(3) = population(2)*3 = population(0)*3²*3 = population(0)*3³

Therefore the equation that will model the growth of the population is:

population(n) = 100*3^n

1. a.

We first need to convert the time from minutes to hours, to do that we must divide by 60. We have:

time = 90/60 = 1.5

We then apply this value in the "n" from the equation above:

population(1.5) = 100*3^(1.5) = 519.615

1.b.

We have to follow the same steps as before:

time = 30/60 = 0.5

population(0.5) = 100*3^(0.5) = 173.21

2.

We now use the same equation as before, but we want to solve for n isntead of "population". We have:

1000 = 100*(3^n)

100*(3^n) = 1000

3^n = 1000/100

3^n = 10

ln(3^n) = ln(10)

n*ln(3) = ln(10)

n = ln(10)/ln(3) = 2.095

It would take approximately 2.1 minutes

Answer:

Y=17

X=17√2

Step-by-step explanation:

1) This triangle is a right isosceles triangle. You know this because it is marked in that way.

2) In an isosceles triangle, the legs are congruent. That means, if one leg is x, then the other leg will also be x.

- In this case, (y) will be 17 because the other leg is also 17.

3) According to pythagorean theorem, a^2 + b^2 = c^2. The hypotenuse is directly across the 90º angle. So, in this case, knowing that both legs are 17,

you can write  17^2 + 17^2 = c^2

(c = x) because i'm just substituting the values.

So now, solve it. You will get

289 + 289 = c^2

c^2 = 578

now just square root 578.

(remember c = x)

You get that x = √578 = 17√2

Answer:

[tex]30cm^3[/tex]

Step-by-step explanation:

the volume of a cylinder is given by:

[tex]v_{cylinder}=\pi r^2 h[/tex]

and the volume of a cone is given by:

[tex]v_{cone}=\frac{\pi r^2 h}{3}[/tex]

since both have the same height and radius, we can solve each equation for [tex]r^2h[/tex] (because this quantity is the same in both figures) and then match the expressions we find:

from the cylinder's volume formula:

[tex]r^2h=\frac{v_{cylinder}}{\pi}[/tex]

and from the cone's volume formula:

[tex]r^2h=\frac{3 v_{cone}}{\pi}[/tex]

matching the two previous expressions:

[tex]\frac{v_{cylinder}}{\pi} =\frac{3v_{cone}}{\pi}[/tex]

we solve for the volume of a cone [tex]v_{cone}[/tex]:

[tex]v_{cone}=\frac{\pi v_{cylinder}}{3\pi} \\\\v_{cone}=\frac{v_{cylinder}}{3}[/tex]

substituting the value of the cylinder's volume [tex]v_{cylinder}=90cm^3[/tex]

[tex]v_{cone}=\frac{90cm^3}{3} \\\\v_{cone}=30cm^3[/tex]

Answer:

volume of the cone = 30 cm³

Step-by-step explanation:

first write both the formula for  finding the volume a cone and a cylinder

volume of a cone = [tex]\frac{1}{3}[/tex] πr² h

where r is the radius of the cone and h is the height of the cone

volume of a cylinder = πr²h

where r is the radius of the cylinder  and h is the height of a cylinder

since the cone and the cylinder has the same height and they are congruent which implies they have the same radius, then

volume of  a cone =   [tex]\frac{1}{3}[/tex] πr² h

                               = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

   from the question given, volume of the cylinder = 90 cm³

volume of a cone = [tex]\frac{1}{3}[/tex] (volume of a cylinder)

                              =[tex]\frac{1}{3}[/tex] × 90

                               = 30 cm³

Therefore, volume of the cone = 30 cm³
