Answer 1

Answer:

C.

Step-by-step explanation:

1.25 + 1.25 = 2.5

Therefore, the graph that goes from 0, to day one at 2.5.

Answer 2

Answer:

C

Step-by-step explanation:

develop an equation

If a dog eats 1.25 cup twice a day:

1.25 x 2 = 2.50

We have the average per day

Y = 2.50x

X represents days

Y = 2.50 x 1

Y = 2.50

We have are coordinate

X = 1

Y = 2.5

( 1 , 2.5 )

Graph C follows that equation and coordinates.

Therefore the answer is C

Answer:

0.25cm^2

97% sure though

Step-by-step explanation:

The general formula to find the total surface area of a prism is: 

Total Surface Area (TSA) = 2 × Base Area + Base Perimeter × Height

TSA = 2 x 0.5 x 0.5 x 0.5

TSA = 0.25

So the surface area of the prism is 0.25cm^2

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.

Which of the following represents the constant of proportionality in the table below?

Answers

The constant of proportionality is the one in option B; k = 95

Which is the constant of proportionality?

Remember that a proportional relation can be written as:

y = k*x

Where k is the constant of proportionality.

Here we can define the variables:

x= months.

y= total revenue.

Now we can use any pair of values in the table to get the constant of proportionality. For example if we use the first pair we get:

x = 2

y = 190

Replacing these values we will get:

190 = k*2

190/2 = k

95 = k

That is the constant of proportionality, the correct option is B.

Answer:

Explanation:

From the graph, we can see that the slope is negative, meaning that we can eliminate two of the answers given to us. Now, looking at the graph, we can see that the line passes (1,2) and (2,4). Find the slope: rise over run. rise is Y or 2 over run, X, 1. 2/1 is 2 (plus the negative sign)

The red dot is the center. The pink is how, long/many boxes.. it is/are there..for the arrow line to reach the point where the other likes meet. Vertical lines are Y and Horizontal lines are X. 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

Maggie has a rectangular box with a length of 6 1/2 inches, a width of 9 inches and a height of 9 1/2 inches.

What is the volume of Maggies box ?\

Answers

6 1/2 x 9 x 9 1/2 = 555.75

Answer:

555 3/4 inches³

Step-by-step explanation:

*To find volume, you just multiply the three lengths together*

1. 6 1/2 x 9 = 58 1/2

2. 58 1/2 x 9 1/2 = 555 3/4

When you do volume, your answer must end in inches "cubed" which is the three that hangs in the air since cubed means to the third power.

(0.35 + 5.2) x. =27.75

Answers

To solve for x, we need to isolate it on one side of the equation.

First, we need to perform the addition inside the parentheses:

5.55 x = 27.75

Next, we can solve for x by dividing both sides of the equation by 5.55:

x = 5

Therefore, the value of x that makes the equation (0.35 + 5.2) x = 27.75 true is 5.

To solve this linear equation, we can re arrange the numbers.

Q) (0.35 + 5.2) x = 27.75

Ans. x (0.35 + 5.2) = 27.75

        0.35x + 5.2x = 27.75

        5.55x = 27.75

        x = 27.75/5.55 = 5

        x = 5

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

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).
