A realtor listed a house that was 45 yards by 10 yards. What is the total square footage of the house?
Answer: There is 1500 squared feet of the house.
Explanation:
Since we have given that
Dimensions of a house is given by
[tex]45\ yards\ and\ 10\ yards[/tex]
So, we need to find the square footage of the house ,
Area of house is given by
[tex]Length\times Breadth\\=45\times 10=4500\ yards^2[/tex]
Now, we'll change it into feet ,
As we know that
[tex]1\ yard=3\ feet[/tex]
So, total squared footage of the house is given by
[tex]\frac{4500}{3}=1500\ feet^2[/tex]
Hence, there is 1500 squared feet of the house.
simplify square root of 1.69
In the given problem, the square root of 1.69 is 1.3.
The square root of a non-negative real number is a value that, when multiplied by itself, results in the original number. In mathematical notation, the square root of the number "x" is represented by the symbol "√x."
The square root is an inverse operation of squaring, which means that if one squares a number and then take its square root, he or she gets back to the original value. The concept of the square root is nearly related to obtaining the side length of a square with a given area or obtaining the magnitude of a vector in mathematics.
1.69 also can be written as [tex]\dfrac{169}{100}[/tex] in fraction form.
[tex]\sqrt{\dfrac{169}{100}} = \sqrt{\dfrac{13^2}{10^2} }[/tex]
[tex]= \sqrt{(\dfrac{13}{10} )^2}\\= \dfrac{13}{10} \\= 1.3[/tex]
Thus, 1.3 is the square root of 1.69.

Charlott is running at a rate of 9 km/h. What is charlotte's speed in m/s?
Answer:
The Charlott's speed in m/s is 2.5 m/sec
Step-by-step explanation:
Given : Charlott is running at a rate of 9 km/h.
We have to find the Charlott's speed in m/s.
Consider the given speed of Charlott is 9 km/h.
Since, 1 km = 1000 m
and 1 hour = 3600 sec
Therefore, [tex]9\frac{km}{hr}[/tex] becomes,
[tex]9\frac{km}{hr}=9\times\frac{1000\ m}{3600 \ sec}=2.5[/tex]
Thus, The Charlott's speed in m/s is 2.5 m/sec

Billy has 1 gallon of paint. He is going to pour it into a paint tray that measures 10 inches wide, 14 inches long, and 4 cm deep.
(1 gallon = 231 in3, 1 inch = 2.54 cm)
hich of the following scenarios will happen?
The paint will not fill the tray by 441 cm3.
The paint will not fill the tray by 10.53 in3.
The paint will fill the tray exactly.
The paint will overfill the tray by 10.53 in3.
find volume of tray:
convert 4cm to inches 4/2.54 = 1.575 inches
volume = 10*14*1.575 = 220.47 cubic inches
1 gallon = 231 cubic inches
231-220.47 = 10.53 more paint in a gallon
so the paint will over fill the tray by 10.53 in3
Answer:
The answer is:
The paint will overfill the tray by 10.53 in3 (cubic inches).
Step-by-step explanation:
In order to determine the correct option, first we have to get the volume of the tray.
The volume of the tray is a solid prism, where its formula is:
width=10 in
length=14 in
deep=4 cm=[tex]\frac{4}{2.54} =1.575[/tex] in
Volume=[tex]10*14*1.57=220.5[/tex] cubic inches
The value of the deep measure was changed from cm to inches units.
We subtract the allowed volume of the gallon with the volume tray:
231-220.5=10.5 cubic inches
It means that 1 gallon of paint is enough to paint the tray, where the remaining paint is 10.5 cubic inches.
Finally, the correct option is:
The paint will overfill the tray by 10.53 in3 (cubic inches).

How to convert from decimal to fraction?For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.
To make them all into decimal points, which allows you to compare them easier than in fraction form. this is done by dividing the denominator by the numerator.
2/3 = 0.66
1/2 = 0.5
1 = 1.00
The answer would be closer to 1/2.

Final answer:
When comparing 2/3 to 1 and 1/2, 2/3 is closer to 1/2 than 1.
Explanation:
When comparing the fraction 2/3 to 1 and 1/2, we can determine which it is closer to by analyzing the numerical values. To do this, we can convert both 1 and 1/2 to fractions with the same denominator as 2/3, which is 3.
1 as a fraction with a denominator of 3 is 3/3. Comparing 2/3 and 3/3, we can see that 2/3 is closer to 1 than 3/3.
On the other hand, 1/2 as a fraction with a denominator of 3 is 3/6. Comparing 2/3 and 3/6, we can see that 2/3 is closer to 1/2 than 3/6.
Therefore, we can conclude that 2/3 is closer to 1/2 than 1.
Create a set of data that contains 11 test scores and satisfies each condition below:
Mean: 83
Median: 81
Mode: 80
Range: 26
Answer:
An example of a data set that satisfies each of these conditions is:
[72, 75, 79, 80, 80, 81, 82, 84, 88, 94, 98]
Step-by-step explanation:
Let's start by defining the terms:
Mean: Average of all numbers
Median: Middle score in a set of given numbers
Mode: Most frequently occuring number
Range: Difference between the lowest and highest number
There are many possible data sets for these conditions, but these are the numbers I found work. I'm sure there is a simpler way to figure this out, but this way makes the most sense to me. This was my process.
We know that all of our numbers need to add up to 913. We know this because our mean is 83 and there are 11 numbers (83X11=913). We can check this by taking 913/11 (the number of scores)=83 (mean)
We know that the median needs to be 81. When the numbers are in order lowest to highest, we would need to have 5 numbers below 81 and 5 numbers above 81. The sixth number in the set should be 81.
We know the mode is 80, so 80 has to be in our data set at least twice with all other numbers appearing less often. This is why I put two 80s and one of every other number in my data set.
I then picked the lowest number in my data set, ensuring that a range of 26 would allow me enough space on both sides of the median. Since I have my lowest number, I can add 26 and get the highest number in my data set.
Once I have the main numbers, I just need to put other numbers before and after the median that would give me a sum of 913 (see the section about the mean). These can be any numbers that go in the right order as long as they don't change any of the numbers we've already established and they total 913.

Farmer George is painting 3 chicken coops. He started painting this morning. Now he only has 3/4 of a chicken coop left to paint this afternoon. how many chicken coops did farmer George paint this morning
Farmer George has painted 2 1/4 chicken coops this morning. This is calculated by subtracting the remaining part of the chicken coop(3/4) from the total chicken coops(3).
Explanation:Farmer George had 3 chicken coops to paint in total. He only has 3/4 of one chicken coop left to paint. We can subtract the amount of work left from the total amount of work to figure out how much work he has done already.
So, if we take the total amount of chicken coops (which is 3) and subtract the remaining part that needs painting (which is 3/4), we will know how many chicken coops Farmer George has painted this morning.
The calculation is as follows: 3 - 3/4 = 2 1/4 coops
So, Farmer George completed painting 2 whole chicken coops and 1/4 of the third chicken coop this morning.

Farmer George painted 2.25 chicken coops this morning. This is calculated as the total number of chicken coops (3) minus the remaining part of the chicken coop left to paint (3/4).
Explanation:The question is asking us about how many chicken coops Farmer George painted this morning. Farmer George started with 3 chicken coops and now has 3/4 of a chicken coop left to paint. Since he's already started painting the last chicken coop, this means he has painted 2 whole coops and 1/4 of the last coop. Thus, the answer to how many chicken coops Farmer George painted this morning is 2.25 chicken coops. Mathematically, this is calculated as 3 (the total number of chicken coops) minus 3/4 (the remaining part of the chicken coop left to paint).
