What is 32.043 in expanded form

Answers

Final answer:

To express 32.043 in expanded form, break it into each digit's value based on its place: 30 (tens) + 2 (ones) + 0.04 (hundredths) + 0.003 (thousandths), resulting in 30 + 2 + 0.04 + 0.003.

Explanation:

The question asks about expressing the number 32.043 in expanded form. Expanded form is a way of writing numbers to show the value of each digit. It involves breaking down the number into each of its digits, multiplied by their respective place value. For the number 32.043:

The '3' is in the tens place, so it represents 30 or 3 * 10.The '2' is in the ones place, so it represents 2 or 2 * 1.The '0' is in the tenths place, so it represents 0 or 0 * 1/10. However, since it contributes no value, it's often omitted in expanded form.The '4' is in the hundredths place, so it represents 0.04 or 4 * 1/100.The '3' is in the thousandths place, so it represents 0.003 or 3 * 1/1000.

Therefore, 32.043 in expanded form is 30 + 2 + 0.04 + 0.003.

Estimate the isoelectric point of a ser–his dipeptide. explain why this value is only an estimate.

Answers

A dipeptide bond connects two amino acids. Ser stands for Serine while His stands for Histidine. Isoelectric point is when all charges of the two amino acids cancel out. This can be estimated by finding the average of the isoelectric points (pI) of the two amino acids.

Serine: pI = 5.68
Histidine: pI = 7.59

Average pI = (5.68 + 7.59)/2 = 6.635

This is only a rough estimate because an arithmetic average will not coincide with the biochemistry of the amino acids. The true value of the isolectric point is determined through experimentation. However, it would be more ore less around 6.635.

A printer prints 28 photos in 8 minutes. a. How many minutes does it take to print 21 more photos? b. Construct a double number line diagram that represents the situation. How many minutes does it take to print 35 more photos?

Answers

now, "21 more photos" is 21 added to the already printed 28, so 21 more is 28+21 photos, or 49,

[tex]\bf \begin{array}{ccll} photos&minutes\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 28&8\\ 49&m \end{array}\implies \cfrac{28}{49}=\cfrac{8}{m}\implies m=\cfrac{49\cdot 8}{28}[/tex]

what about 35 more?   well, it already printed 49, and 35 more would then be 84,

[tex]\bf \begin{array}{ccll} photos&minutes\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 28&8\\ 84&m \end{array}\implies \cfrac{28}{84}=\cfrac{8}{m}\implies m=\cfrac{84\cdot 8}{28}[/tex]

It takes 6 minutes to print 21 more photos. It takes 10 minutes to print 35 more photos.

To determine the time it takes to print 21 more photos, we first need to calculate the rate at which the printer prints photos. We can do this by dividing the number of photos printed (28) by the time it takes to print them (8 minutes). This gives us a rate of 3.5 photos per minute.

Next, we can divide the number of additional photos (21) by the rate of photos per minute to find the time it takes to print them. This gives us 21 photos / 3.5 photos per minute = 6 minutes.

Therefore, it takes 6 minutes to print 21 more photos.

To construct a double number line diagram, we create two parallel number lines, one for the number of photos and one for the number of minutes. We mark the starting point on both lines as 0.

Next, we plot the point (28, 8) on the diagram, representing the fact that 28 photos are printed in 8 minutes.

To determine the time it takes to print 35 more photos, we can extend the number of photos line to the point (35 + 28, 8), which is (63, 8). This point represents the fact that 63 photos are printed in 8 minutes.

Finally, we can draw a vertical line from the point (63, 8) on the number of photos line to the number of minutes line. This line intersects the number of minutes line at the point (63, 8 + 10), which is (63, 18).

Therefore, it takes 10 minutes to print 35 more photos.

if we assume the linear trend existed before 1950 and continues after 2000, the two states’ median house values wil be (or were) equal in what year? (The answer might be absurd.)

Answers

Final answer:

To find the year two states would theoretically have equal median house values, one could use provided growth rates and starting house values to set up an equation and solve for time. However, assuming a linear trend can lead to inaccurate results as real estate markets are affected by many fluctuating factors.

Explanation:

To calculate the year in which two states would have theoretically had equal median house values, we first need to know the starting house values for each state and the annual growth rate trends. We've learned from the FRED® Economic Data that median sales price for a home in the U.S. was $122,900 in 1990 and rose to $232,000 by the end of 2016, an average growth rate of 3.1% annually. In other periods, such as the 1970s, 1980s, and 1990s, housing prices increased about 6% per year on average. During the 'housing bubble' years (2003-2005), they experienced a sharp rise and then a fall with the 2007-2008 recession.

Assuming linear trend (constant growth), we would set up an equation with these variables and solve for the year (time) where the values are equal. However, do kindly note that assuming the same trend can often lead to absurd results as housing markets are affected by a variety of economic, political, and demographic factors and do not always follow a linear trend.

a) Home values have increased at a higher rate in New York.

b) The median home value in Arkansas in 2010 would be $82,400.

c) The two states' median house values were equal in year = 190

Let’s break down each question:

a) To determine which state’s home values have increased at a higher rate, we need to calculate the rate of change for each state. The rate of change is calculated as the difference in home values divided by the difference in years.

For Arkansas, the rate of change is (72,800 - 24,800) / (2000 - 1950) = $960 per year.

For New York, the rate of change is (148,700 - 61,500) / (2000 - 1950) = $1,744 per year.

So, home values have increased at a higher rate in New York.

b) If these trends were to continue, the median home value in Arkansas in 2010 would be the 2000 home value plus the rate of change times the number of years since 2000.

So, the median home value in Arkansas in 2010 would be 72,800 + $960 * (2010 - 2000) = $82,400.

c) If we assume the linear trend existed before 1950 and continues after 2000, the two states’ median house values will be equal when the equation for Arkansas’s home values equals the equation for New York’s home values.

We are given that the median home value in Arkansas in 1950 was $24,800 and in 2000 it was $72,800. This gives us a rate of increase of $960 per year. So, the value of a home in Arkansas in year ‘x’ can be represented by the equation:

[tex]V_{Arkansas}(x) = 24800 + 960 * (x - 1950)[/tex]

Similarly, the median home value in New York in 1950 was $61,500 and in 2000 it was $148,700. This gives us a rate of increase of $1,744 per year. So, the value of a home in New York in year ‘x’ can be represented by the equation:

[tex]V_{NewYork}(x) = 61500 + 1744 * (x - 1950)[/tex]

The two states’ median house values will be equal when

[tex]V_{Arkansas}(x) = V_{NewYork}(x)[/tex]

Setting the two equations equal to each other and solving for ‘x’ gives us:

[tex]24800 + 960 * (x - 1950) = 61500 + 1744 * (x - 1950)[/tex]

[tex]24800+960x-1872000=61500+1744x-3400800\\784x=149100\\x=190.17[/tex]

We round it to the nearest whole number because it represents a year.

So, the two states' median house values were equal in year = 190

Complete Question:

The median home value in Arkansas and New York (adjusted for inflation) are shown below:

Year Arkansas  New York

1950 24,800 61,500

2000 72,800 148,700

If we assume that the house values are changing linearly,

a) In which state have home values increased at a higher rate?

b) If these trends were to continue, what would be the median home value in Arkansas in 2010?

C) If we assume the linear trend existed before 1950 and continues after 2000, the two states' median house values will be (or were) equal in what year? (The answer might be absurd)

if the area of a garden is 11 square feet what could be the dimensions of the garden

Answers

Assuming that the garden is rectangular in shape, the area of a rectangle is given by length x width.

11 is a prime with factors 1 and 11.

Therefore, if the area of a (rectangular) garden is 11 square feet, then the possible dimension of the garden is 1 feet by 11 feet.
Final answer:

There can be multiple possible dimensions for a garden with an area of 11 square feet depending on its shape. For example, the garden could be 1ft by 11ft, 2ft by 5.5ft, or even a square with each side measuring 3.32 ft.

Explanation:

The area of a garden is calculated by multiplying its length by its width. As the area of the garden is given as 11 square feet, possible dimensions for the garden could be 1 foot by 11 feet, 2 feet by 5.5 feet, or any other combinations that, when multiplied, give the result as 11 square feet.

Another way to look at it is that if you imagine the garden as a perfect square shape, each side would be approximately 3.32 feet since 3.32 multiplied by 3.32 equals roughly 11. This is because the square root of 11 is about 3.32.
