The conversion of 64kg in pounds  is equivalent to approximately 141.09568 pounds.

The kilogram (kg) is the SI unit of mass. It is equal to the mass of the international prototype of the kilogram. This prototype is a platinum-iridium international prototype kept at the International Bureau of Weights and Measures. One kg is approximately equal to 2.20462262184878 pounds.One pound, the international avoirdupois pound, is legally defined as exactly 0.45359237 kilograms.

To convert 64 kilograms to pounds, you can use the conversion factor of 1 kilogram = 2.20462 pounds.

Therefore,64 kilograms = 64 x 2.20462 pounds

= 141.09568 pounds (rounded to 5 decimal places)

As per the conversion, the weight of 40 pounds is equivalent to a weight of 18.14 kilograms.

Converting measurements can sometimes be a tricky task, especially when we need to convert from one unit to another. One common conversion that we often encounter is the conversion of pounds to kilograms. In this guide, we will explain step by step how to convert 40 pounds into kilograms.

First, we need to understand the basic unit of measurement for both pounds and kilograms. Pounds are a unit of measurement commonly used in the United States and the United Kingdom to measure weight. Kilograms, on the other hand, are the standard unit of measurement for weight in the International System of Units (SI).

To convert 40 pounds to kilograms, we need to use the following formula:

1 pound = 0.45359237 kilograms

Using this formula, we can calculate the equivalent weight in kilograms for 40 pounds. We simply multiply 40 by 0.45359237 to get:

40 x 0.45359237 = 18.14374948 kilograms

So, 40 pounds is equivalent to 18.14374948 kilograms (rounded off to the nearest hundredth) we get 18.14 kilograms.

The average read speed is defined as the rate at which a person can read and comprehend written text

The average read speed refers to the rate at which a person can read and comprehend written text. This is typically measured in words per minute (wpm). According to studies, the average reading speed for adults is around 200 to 300 wpm, although this can vary depending on factors such as reading proficiency, familiarity with the material, and reading conditions.

Factors that can affect reading speed include:

Word length and complexity: Longer and more complex words can slow down reading speed.

Font size and style: Smaller fonts and difficult-to-read styles can also slow down reading.

Reading experience: Frequent readers tend to have higher reading speeds than occasional readers.

Comprehension level: Reading speed can decrease if the reader is trying to understand difficult or technical material.

It's important to note that while reading speed is a useful metric, it's not always the most important factor in reading. Comprehension and retention of the material are also crucial, so it's important to find a balance between reading speed and comprehension.

If she is working at a constant rate, 12 rows had been completed before Elena started working.

To determine the number of rows that were completed before Elena started working, we need to find the equation of the line that represents the relationship between the number of rows completed and the time taken.

We can use the two given points (14, 19) and (20, 22) to find the slope of the line:

slope = (change in rows) / (change in time) = (22 - 19) / (20 - 14) = 3 / 6 = 1/2

Next, we can use the slope and one of the points to find the y-intercept of the line using the point-slope form of a line:

y - 19 = (1/2)(x - 14)

y - 19 = (1/2)x - 7

y = (1/2)x + 12

Now that we have the equation of the line, we can use it to find the number of rows completed when x (time) is equal to 0, which represents the point when Elena started working:

50cm is equal to 19.685 inches.

Measurement is a crucial aspect of our lives, and it helps us to determine the quantity, size, or amount of things. Different units of measurement are used to measure various objects, and it is essential to know how to convert from one unit to another. In this article, we will discuss how to convert 50cm to inches, which are both commonly used measurements.

To convert 50cm to inches, we need to know the conversion factor between centimeters and inches. One inch is equal to 2.54 centimeters, which means that we can convert centimeters to inches by dividing the measurement by 2.54.

So, to convert 50cm to inches, we need to divide 50 by 2.54. We can do this using a calculator or by long division.

50 / 2.54 = 19.685 inches

Answer:

To solve the inequality |h + 3| < 5, we need to consider two cases, depending on whether the expression inside the absolute value bars is positive or negative:

Case 1: h + 3 >= 0

If h + 3 >= 0, then we can remove the absolute value bars without changing the inequality:

h + 3 < 5

Subtracting 3 from both sides, we get:

h < 2

So the solution for this case is h < 2.

Case 2: h + 3 < 0

If h + 3 < 0, then the inequality becomes:

-(h + 3) < 5

Multiplying both sides by -1 (and reversing the inequality), we get:

h + 3 > -5

Subtracting 3 from both sides, we get:

h > -8

So the solution for this case is h > -8.

Putting these two solutions together, we have:

-8 < h < 2

Therefore, the solution set in set-builder notation is:

{h | -8 < h < 2}

The measure of angle x in the isosceles triangle is 40 degrees.

Let's call the two congruent sides of the isosceles triangle "a" and the remaining side "b". Since the angle opposite one of the congruent sides (let's call it "a") is 70 degrees, the other angle opposite "a" must also be 70 degrees due to the property of isosceles triangles. Let's call this angle "y".

So we have two angles that add up to 140 degrees (70 + 70 = 140). We also know that the sum of the angles in any triangle is always 180 degrees. Therefore, we can find the measure of angle "x" as follows:

x + y + 70 = 180

Substituting y = 70, we get:

x + 70 + 70 = 180

Simplifying the equation, we get:

x + 140 = 180

Subtracting 140 from both sides, we get:

Answer: Rounding to the nearest whole number, we can estimate that about 194 people should be expected to visit the Fiction and Literature section on Sunday.

Step-by-step explanation:

To estimate how many people to expect in the Fiction and Literature section on Sunday, we can assume that the proportion of visitors to each section remains the same as it was on Saturday.

First, we need to calculate the total number of visitors on Saturday:

433 (Youth Wing) + 335 (Social Issues) + 367 (Fiction and Literature) = 1135

Next, we can find the proportion of visitors to the Fiction and Literature section:

367 (Fiction and Literature) / 1135 (total visitors on Saturday) ≈ 0.323

We can use this proportion to estimate the number of visitors to the Fiction and Literature section on Sunday:

0.323 (proportion of visitors to Fiction and Literature) x 600 (total visitors on Sunday) ≈ 194

Rounding to the nearest whole number, we can estimate that about 194 people should be expected to visit the Fiction and Literature section on Sunday.

The greatest common factor (GCF) of 42, 126, and 210 is 42.

To find the GCF, you can use several methods such as prime factorization or the Euclidean algorithm. One way to find the GCF using prime factorization is to express each number as a product of its prime factors:

42 = 2 × 3 × 7

126 = 2 × 3² × 7

210 = 2 × 3 × 5 × 7

Then, identify the common prime factors and their smallest exponent across all three numbers. In this case, the common prime factors are 2, 3, and 7. The smallest exponent of 2 is 1, the smallest exponent of 3 is 1, and the smallest exponent of 7 is 1. Therefore, the GCF is

= 2 × 3 × 7

= 42

Another method to find the GCF is the Euclidean algorithm, which involves finding the remainder of dividing the larger number by the smaller number repeatedly until the remainder is zero. The GCF is the last nonzero remainder. However, in this case, the prime factorization method is simpler and quicker.

Answer:

Step-by-step explanation:

At the start, Sai owes his mum $390. After the first month, his mum reduces his debt by 5% of $390, which is 0.05 x $390 = $19.50. So at the end of the first month, he owes his mum $390 - $19.50 = $370.50.

After the second month, his mum reduces his debt by 5% of $370.50, which is 0.05 x $370.50 = $18.53. So at the end of the second month, he owes his mum $370.50 - $18.53 = $351.97.

After the third month, his mum reduces his debt by 5% of $351.97, which is 0.05 x $351.97 = $17.60 (rounded to the nearest cent). So at the end of the third month, he owes his mum $351.97 - $17.60 = $334.37.

Therefore, Sai owes his mum $334.37 at the end of three months.
