How do I write 6 x 3/20 as a fraction in simplest form?
Answers
To simplify 6 x 3/20, we first perform the multiplication to get 18/20. Then, we divide both the numerator and denominator by their greatest common divisor, which is 2, resulting in 9/10.
Explanation:Firstly, in the given expression, 6 x 3/20, the order of operations (BIDMAS/BODMAS) requires us to perform multiplication and division from left to right. So, we multiply 6 and 3 to get 18. This gives us a new expression, 18/20. Then, we simplify this fraction by finding the highest number that both the numerator (18) and denominator (20) can be divided by, which is 2. So we divide both by 2, getting us 9/10. So, 6 x 3/20 simplifies to 9/10 in its simplest form.

Explanation of determining between which two consecutive integers a square root lies.To find out between which two consecutive integers numbers like √18, √29, √5, and √79 lie, we use the squares of integers to estimate their positions without a calculator, illustrating these numbers lie between integers whose squares are immediately below and above the given number.
Explanation:
To determine between which two consecutive integers a given square root lies without a calculator:
For<6: √18 is between 4 and 5 because 4< √18<5.
For<5: √29 is between 5 and 6 because 5< √29<6.
For=5: √5 is between 2 and 3 because 2< √5<3.
For>7: √79 is between 8 and 9 because 8< √79<9.
What is the answer to 45,469.23 rounded to the nearest thousand?
Answers
When rounding numbers to the nearest thousand, you look at the hundreds place digit. If it's 5 or higher, you round up, and if it's 4 or lower, you don't. Therefore, 45,469.23 rounds down to 45,000.
Explanation:When rounding numbers to the nearest thousand in mathematics, you must first look at the hundreds digit of the number. In the case of 45,469.23, the hundreds digit is 4. If this digit is 5 or higher, you round up; if it's 4 or lower, you don't round up. Therefore, since the digit in question is 4, which is less than 5, you don't need to increase the thousands digit. As a result, when you round 45,469.23 to the nearest thousand, you get 45,000.

To convert degrees Fahrenheit (F) into degrees Celsius (C) use the formula 2003-05-04-00-00_files/i0150000.jpg. Rewrite the equation to convert degrees Celsius to degrees Fahrenheit.
Answers
To convert Celsius to Fahrenheit, use the formula [°F] = [°C] x 9/5 + 32. For example, a 16°C temperature would convert to approximately 60.8°F.
The formula you are looking for to convert degrees Celsius to degrees Fahrenheit is [°F] = [°C] x 9/5 + 32. To perform the conversion, you multiply the temperature in degrees Celsius by 9/5 (or 1.8) and then add 32 to the result. This will give you the temperature in degrees Fahrenheit.
For example, if you wanted to convert 16°C to Fahrenheit (perhaps for planning a trip to Spain), you would do the following calculation: [°F] = 16 x 9/5 + 32 = 28.8 + 32 = 60.8°F. Thus, a weather forecast predicting 16°C is approximately equivalent to 60.8°F.

Answers
Answer:
(a+1)(a+27)
Step-by-step explanation:
Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial [tex]Ax^2+Bx+C[/tex] multiply A*C then find two numbers which multiply to this number and add to B. When you find those numbers, write them as [tex](x-/+ number)(x-/+number)[/tex].
[tex]a^2+28a+27[/tex]
A=1, C=27
A*C=27 and add to B=28 which 1 and 27 satisfy
The factors are (a+1)(a+27)
Liam's bookstore sold 40 notebooks and 20 newspapers for a total of $130. A day later, the bookstore sold 8 notebooks and 4 newspapers at the same prices, for a total of $28. How much does a notebook and a newspaper cost at Liam's bookstore?
Answers
40x + 20y = 130
and 8x + 4y = 28
With this, if we divide the left hand side by the left hand side of the equation number 2, we have 5. However, 130 divided 28 is not 5 but 4.64. Hence, the system does not have any solution.
Let us say that:
X = price of each notebook
Y = price of each newspaper
So from the problem statement we can create the following equations:
40 X + 20 Y = 130 --> eqtn 1
8 X + 4 Y = 28 --> eqtn 2
Divide both equations by the lowest coefficient to simplify:
Divide eqtn 1 by 20 => 2 X + Y = 6.5
Divide eqtn 2 by 4=> 2 X + Y = 7
So we can see that although both equations has equal left side, the right side do not match. Hence this problem is impossible to solve.

The question involves understanding square roots and cube roots in mathematics. The square root of 16 is 4 and of 4 is 2. The cube root of 4 is about 1.587 and of 16 is approximately 2.52.
Explanation:The question is related to the concept of roots, specifically square roots and cube roots. A square root of a number is a value that, when multiplied by itself, gives the original number. The square root of 16 is 4 because 4*4 equals 16. Similarly, the square root of 4 is 2 because 2*2 equals 4.
On the other hand, the cube root of a number is a value that, when multiplied by itself twice, gives the original number. The cube root of 4 is approximately 1.587 because 1.587*1.587*1.587 is roughly equal to 4. The cube root of 16 is approximately 2.52 because 2.52*2.52*2.52 is roughly equal to 16.

How to find the y-intercept from two points?
Answers
To find the y-intercept from two points, first calculate the slope using the formula m = (Y₂ - Y₁) / (X₂ - X₁). Then, substitute the slope and one coordinate into the equation y = mx + b and solve for b, which is the y-intercept. The y-intercept reveals the value of y when x = 0.
Explanation:The subject at hand pertains to the field of Mathematics, specifically, how to determine the y-intercept from two points on a line. The objective is to find the point at which the line intercepts the y-axis, denoted generally in equations as b in the form of y = mx + b, where m signifies the slope.
Here's a step-by-step process to find the y-intercept:
First, calculate the slope (m) from your two points using the formula: m = (Y₂ - Y₁) / (X₂ - X₁). Y₂ and Y₁ represent the y-values from your two points, and X₂ and X₁ represent their respective x-values.Substitute the slope (m) and one of your points into the equation y = mx + b. Solve for b which is your y-intercept.The y-intercept represents the value of y when x = 0. In context, it shows where the line crosses the y-axis.

According to the data reported by the new york state department of health regarding west nile virus for the years 2000-2004, the least squares line equation for the number of reported dead birds (x) versus the number of human west nile virus cases (y) is y = −10.2638 + 0.0491x. if the number of dead birds reported in a year is 748, how many human cases of west nile virus can be expected? (round your answer to the nearest whole number.)
Answers
Final answer:
Using the least squares line equation y = −10.2638 + 0.0491x and substituting 748 for x, the number of reported dead birds, we find the expected number of human West Nile virus cases to be approximately 26 when rounded to the nearest whole number.
Explanation:
The question asks to predict the number of human West Nile virus cases based on the number of reported dead birds using a least squares line equation provided. Given the equation y = −10.2638 + 0.0491x and the value x = 748, which represents the number of dead birds, we can substitute x into the equation to calculate y, the expected number of human cases.
The calculation is as follows:
y = −10.2638 + 0.0491 × 748
y = −10.2638 + 36.7268
y = 26.463
After performing the calculation, we round the result to the nearest whole number:
Expected number of human cases = 26

Use an estimation strategy to determine how much Isaac will pay if the total bill is $97.65. Show the step-by-step process you used to solve the problem.
Answers
for estimating round both the price of shoes and the percentage to round numbers
97.65 is close to 100, so use 100 for the price of shoes
68% is close to 70 so use 70%
then multiply 100 by 70 %,
100 *70% = 70 dollars
so Isaac would pay around 70 dollars
Step-by-step explanation:
first you need to see how much his sister is paying and she is paying 32% and that is 31.24 then you need to subtract 97.65 by 31.24 which will equal 66.41 so Isaac will pay $66.41 hope this helps if your going to use it change the wording up a bit
