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]
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
1. How much did the population change between 1950 and 1960? What was the average annual change for that period? Hint: Calculate the changes, then calculate the mean, or average, by dividing by the number of years. State the units clearly. The units are listed on the chart.
2. Repeat question 1 for the period between 1970 and 1980; between 1990 and 1995.
3. Do you think a linear model (or graph) would best illustrate this data? Explain your reasoning.
Answer:
0.484 billion 0.0484 billion per year
Step-by-step explanation:
Population change between 1950 and 1960 = 3.039 - 2.555 = 0.484 (billion)
Number of years between 1950 and 1960 = 1960 - 1950 = 10 years
Average population change per year = 0.484 ÷ 10 = 0.0484 billion per year

Answer:
Step-by-step explanation:
The 1960 Census of Population is providing a vast amount of detailed statistics reflecting the widespread redistribution of the population during the 1950's. The pattern of population movement during the 1950's parallels, to a great extent, that which occurred during the 1940's, particularly after World War II. To permit better understanding of the population movement, that has occurred from 1950 to 1960, the Bureau of the Census has undertaken the compilation of statistics on the separate components of population change for counties. This is the first time that, estimates of net migration have ever been published for all the counties in the United States. By combining groups of counties into certain widely used statistical areas, such as the standard metropolitan statistical area, State economic area, and economic subregion, one can obtain a broader picture of population movement in the United States.

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

In Δ JKL, ∠ K measures 50° and ∠ J ≅ ∠ L. Which is the measure of ∠ J?
Answer:
∠J = 65°
Step-by-step explanation:
x + x + 50 = 180
2x + 50 = 180
2x = 180 - 50
2x = 130
x = 130/2
x = 65

Solve the inequality $-8r<-12$.
Please help i will put up 10 points
Answer:
Step-by-step explanation:
im assuming you solve for r.
-8r<-12
divided by -8 on both sides so you change signs
r>12/8
r> $ 3/2
Answer:
$r > 1.5$ or [tex]\frac{3}{2}[/tex]$
Hope this helps!
Step-by-step explanation:
Hiding the dollar signs real quick:
-8r < -12
Divide both sides by -8: ( remember that when multiplying or dividing both sides by a negative number reverses the inequality )
-8 ÷ -8 × r < -12 ÷ -8 = r > 1.5 or [tex]\frac{3}{2}[/tex]

Answer:
A = 324m²
Step-by-step explanation:
Formula for finding the surface area of a rectangular prism:
2(wl + hl + hw)
First, let's find out which one of the measurements is the height, length, or width.
6m = length
16m = width
3m = height
Next, we calculate the surface area. We have to do the formula one by one too.
2(wl + hl + hw)
2(16x6 + 3x6 + 3x16)
16 x 6 = 96
3 x 6 = 18
3 x 16 = 48
Now, we add those together.
96 + 18 + 48 = 162
Lastly, multiply by 2.
162 x 2 = 324
Therefore, A = 324m²

Display the data in the histogram
Answer:
x=-3/4+1
Step-by-step explanation:
its easy
The histogram of the given data is attached. A histogram is a graphical representation of the distribution of numerical data. It consists of a set of rectangles, or bins, placed side by side along a horizontal axis.
The width of each bin in the histogram represents a range of values, and the height of each bin represents the frequency or count of data points that fall within that range.
Histograms are commonly used to visualize the shape of a data distribution, including its center, spread, and any outliers or gaps. They can also reveal patterns or trends in the data, such as skewness, bimodality, or multimodality.
Histograms are often used in statistics, data analysis, and scientific research to explore, summarize, and communicate information about datasets. They are a powerful tool for understanding and interpreting numerical data, and can help to identify important features or insights that might be missed by other types of visualizations.

What is the slope?
Simplify your answer and write it
as a proper fraction, improper
fraction, or integer.
The slope of the linear function in this problem is given as follows:
m = 3.
How to define a linear function?The slope-intercept representation of a linear function is given by the equation presented as follows:
y = mx + b
The coefficients of the function and their meaning are described as follows:
m is the slope of the function, representing the change in the output variable y when the input variable x is increased by one.b is the y-intercept of the function, which is the initial value of the function, i.e., the numeric value of the function when the input variable x assumes a value of 0. On a graph, it is the value of y when the graph of the function crosses the y-axis.From the graph, when x increases by two, y increases by six, hence the slope m of the function is given as follows:
m = 6/2
m = 3.

What's the measure of G? FInd the measures of all missing angles.
Answer:
angle G= 135°
angle E = 45°
angle D = 64°
angle B= 45°
angle C = 71°
Step-by-step explanation: Since ∆ABC~∆DEF
therefore angle A~angle D
angle B~angle E and angle C ~angle F
angle G = 180°- angle
i.e. 180° - 45° = 135°
reason :sum of angles on a straight line is 180°

Answer:
280ml of oil.
Step-by-step explanation:
The first step to finding how much oil he should use, turn 5 : 2 into a fraction.
5 Since we know he uses 700ml of mayo, we use that to find the
2 amount of oil.
We use cross multiplication and use x for the amount of oil.
x = oil
5 = 700
2 x
2 x 700 = 1,400
1,400 ÷ 5 = 280
x = 280
In order to confirm if this is true, we check if the ratios are equivalent.
5/2 = 700/280
simplify 700/280 by finding the gcf
GCF = 140
700 ÷ 140 = 5
280 ÷ 140 = 2
5 : 2 or 5/2
Therefore, it is correct
