Petra is making a batch of extra large donuts by stamping circles in dough using a pastry stamp with a diameter of 5 inches. For the donut hole, she stamps out a circle using a pastry stamp that has a diameter of 2 inches.

How many square inches of dough are left in the donut after the hole has been removed?

Step 1 - Find the radius of each circle

Step 2 - Find the area of the large circle

Step 3 - Find the area of the small circle

Step 4 - Area of large circle minus area of small circle

Area = [tex]\pi[/tex]²


Describe how you solved this problem using complete sentences and include all relevant formulas and calculations. Use 3.14 for [tex]\pi[/tex]

Answers

Answer:

16.49

Step-by-step explanation:

First we are going to find the area of the larger circle. You don't need to find the radius, you can just use the diameter(the radius is 2.5). 3.14 times 2.5 squared=19.63. Next, the radius of the smaller circle is 1. So, 3.14 ^1 squared=3.14 19.63 - 3.14= 16.49

Answers

Answer:

C.)

Step-by-step explanation:

(0 minutes = 60 gallons)

1 minute passes = 60-12 = 48

(2 minutes pass = 48-12 = 36)

3 minutes pass = 36 - 12 = 24

4 minutes pass = 24 - 12 = 12

Show work and explain!! Due in 12 hours! Find the total volume of these 2 shapes.

Answers

Answer:

86,205.3 cm³

Step-by-step explanation:

So first you have to know the formulas. The volume of a cone is V= 1/3 π r²×H. The volume for a sphere is V= 4/3πr³. But, in this instance the sphere is cut in half, so what we would do is just divide the formula by 2. We are going to start with the cone. plug in the answers. r=28 and H=49. you can always, for pie, plug it in for 3.14, depending on your calculator and teacher. It should look like V=1/3π28²×49. So, for that answer you should get, 40,229.14cm³. Next is the half sphere. Plug in what is necessary, r=28. It should look like, V=4/3π28³. You should get 91952.32cm³, but remeber you have to half it so takes that answer and divde by 2. Then your answer is 45976.16cm³. After done just add your two sums together and you should get 86205.3cm³.

Kelly owns a comic book that is currently worth $840, and she believes that its value will increase by $30 every year. Kelly plans to sell the comic book for $1,500 and wants to know how long she must wait until the comic book's value reaches at least 90% of that amount.
This problem can be solved with an inequality that uses the variable x.
How should x be defined?
x = the number of years until the comic book is worth 90% of $1,500
x = the price Kelly plans to sell the comic book for
x = the current value of the comic book
x = the number of years Kelly has already owned the comic book

In fractions. Y is over X always. So if the arrow is going up or down then the # of boxes you count going up is your Y. In this case.. the Y is 2. Because it only takes two boxes going up until the arrow reach this the corner of of the boxes. And X is 1 because it only takes one box to the left to get to the corner. Basically it is 2/1 (2 over 1) but since 1 is the denominator then the number on top (2) is a whole #. That is why the answer to your question is 2x

Micah uses the coordinate grid to draw a rectangle. Three verticles of the rectancle are (-4, 5),(-4,3) and (6,5). What are the coordinates of the fourh vertex? show micahs rectangles on the coordinate grid

Answers

Answer:

(6, 3)

Step-by-step explanation:

We already have two coordinates that make one side of the rectangle up.

(-4, 5) and (-4, 3)

Notice how only the y-coordinates change.

So, based on this logic, we should get:

(6, 5) and (6, 3)

So, the missing coordinate is (6,3)

Answer:

(6,3) is the missing 4th vertex.

Step-by-step explanation:

We know that, a rectangle is made up of 4 sides , 4 vertices and 4 edges.

According to the question, there are 3 vertices marked.

The three vertices are:

(-4,5)(-4,3)(6,5)IMPORTANT NOTE

If we are measuring the sides of a quadrilateral on a coordinate grid, we have to remember that each and every point comes twice in adjacent sides.

For example:

In the given figure, (-4) and 5 appeared twice in the three given vertices.

Now, we should remove (-4) and 5 from the three vertices.

We will be left with 6 and 3.

So, the 4th point will be the combination of 6 and 3.

Hence, we will get the 4th point as (6,3).

She needs 108 inches because you have to multiply 6 and 2 first, which makes 12. And then you have to multiply 3 and 3, which makes 9.

1. Is the average change in population the same now as it was 50 years ago? Explain your answer.

2. Reflect on the interpretation of your data.

3. What should you consider when comparing population growth (or decline) over different intervals of time? Hint: What factors influence population growth or decline? Explain fully and provide examples where needed.

Answers

1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.

2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.

3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.

New flooring: the bedroom floor is the shape of a rectangle. It is 15 feet long and 12 feet wide. You want to have liquid flooring tiles installed. Your parents choice is oak flooring. The oak flooring costs $4.25 per square foot for materials. The liquid floor tiles cost $245 per tiles is 2 x 2 (4 square feet each.) the cost for labor will be the same for either flooring option and is $1.70 per square foot. Paint the walls: The height of the bedroom is 9 feet. There are 4 rectangular windows in the room that are each 30 inches wide and 36 inches high. You will not paint the windows, the floor, or the ceiling. You will paint the rest of the room including your door. Your choice for paint is Glow in the Dark paint. Your parents choice is a regular paint. Both colors are only available in 1-gallon cans. The price for a 1-gallon can of regular paint is $24, but it is on sale for 25% off the regular price. This type of paint requires 2 coats. Glow in the dark paint: the price of a 1-gallon can is $125. This type of paint only requires 1 coat.
