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:

79

Hope this helps!

Step-by-step explanation:

PEMDAS: parentheses, exponents, multiplication, division, addition, and subtraction. ( also go from left to right )

1 + 1 = 2 + 4 = 6 + 5 = 11 - 7 = 4 + 75 = 79

Answer: 91

Step-by-step explanation: hope it helps!

20 it's because you will take the w (width) and l (length) which is w=5

and l=4 and the answer is l x w so 5 x 4 = 20

Answer:

b)

Step-by-step explanation:

Supplementary angles add up to 180 degrees, so the answer must be b).  Let's check the math:

77 + (5x + 18) = 180

-77                    -77

(5x + 18) = 103  --> here we already know this is correct, as the problem tells us that angle H is equal to this equation, (5x + 18), and we know that it is also equal to 103.

Answer:

6 ft

Step-by-step explanation:

Given:

r (radius) = 3 ft

Find: d (diameter) - ?

The diameter of a circle is equal to double radius:

[tex]d = 2r[/tex]

[tex]d = 2 \times 3 = 6 \: ft[/tex]

Answer:

A. $3.56

Step-by-step explanation:

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:

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).

Answer: 29%

Step-by-step explanation: 58-45 13/45=29

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

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°

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.

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.

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

Answer:

1200

Step-by-step explanation:

Convert 48.5% into decimal form.

This can be done by dividing the percentage by 100.

48.5 divided by 100 is 0.485.

Next, you simply just divide the given number, in this case, 582, by the decimal that you got.

582 divided by 0.485 is 1200.

1200 is the answer.

Answer:

∠J = 65°

Step-by-step explanation:

x + x + 50 = 180

2x + 50 = 180

2x = 180 - 50

2x = 130

x = 130/2

x = 65

Answer:

angle F = 45, angle J = 25, no they aren't similar

Step-by-step explanation:

angle F = 180 - (100 + 35)

angle F = 45

angle J = 180 - (100+55)

angle J = 25

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

5 minutes pass = 12 - 12 = 0

Answer:

90 degrees is a right angle, and is in the corner of this text box, or this: |_

40 degrees is an acute angle, a little less than half 90 degrees, like this: <

135 degrees is an obtuse angle, and is 90 degrees + 45 degrees.

Also, something important to remember when drawing this is that 180 degrees is half of a circle, and 360 degrees is a full circle.
