Final answer:
A multiple of 1/10 is any fraction obtained by multiplying 1/10 by an integer. For example, 1/10 multiplied by 2 is 2/10, which simplifies to 1/5. Dividing by powers of 10 shifts the decimal point left, making 1.9436 divided by 1,000 equal to 0.0019436.
Explanation:
In mathematics, when identifying a multiple of a fraction, you look for fractions that can be created by multiplying the original fraction by an integer. In the case of 1/10, a multiple would be any fraction where 1/10 is multiplied by a whole number.
For instance:
1/10 multiplied by 2 is 2/10, which simplifies to 1/5 - thus 1/5 is a multiple of 1/10.1/10 multiplied by 3 is 3/10 - hence, 3/10 is a multiple of 1/10.Multiplying 1.9436 by powers of 10 shifts the decimal point accordingly:
1.9436 × 10 = 19.4361.9436 × 100 = 194.361.9436 × 1,000 = 1,943.6Conversely, dividing by powers of 10 will shift the decimal point to the left, making the number smaller:
1.9436 ÷ 10 = 0.194361.9436 ÷ 100 = 0.0194361.9436 ÷ 1,000 = 0.0019436The fraction 15 can be simplified by dividing both the numerator and the denominator by the greatest common factor, in this case, 15, yielding a value of 1.
one hundred grams of radium are stored in a container. The amount R of radium present after t years can modeled by R=10e^-0.00043t. After how many years will only 5 grams of radium be present? round your answer to the nearest whole year.
To determine after how many years only 5 grams of radium will be present, we use the decay equation [tex]R = 100e^{-0.00043t}[/tex] to solve for t when R equals 5 grams, yielding approximately 1,605 years.
Explanation:To determine after how many years only 5 grams of radium will be present, we can use the provided equation for radioactive decay: R = [tex]100e^{-0.00043t}[/tex]. We need to solve for when R equals 5 grams. Here are the steps:
Set the equation equal to 5: [tex]5 = 100e^{-0.00043t}.[/tex]Divide both sides by 100: [tex]0.05 = e^{-0.00043t[/tex]}.Take the natural logarithm (ln) of both sides to solve for t: [tex]ln(0.05) = ln(e^{-0.00043t}) = -0.00043t.[/tex]Divide both sides by -0.00043 to isolate t: [tex]t = ln(0.05) / -0.00043.[/tex]Use a calculator to find the value of t: [tex]t \approx 1,605.11[/tex] years.Round to the nearest whole year: t ≈ 1,605 years.After approximately 1,605 years, only 5 grams of radium will be present.
To find the time after which only 5 grams of radium remain, the exponential decay equation [tex]R = 10e^{-0.00043t[/tex] is solved using natural logarithms, yielding an approximate time of 1608 years.
To determine after how many years only 5 grams of radium will be present, we need to solve the exponential decay equation provided, R = [tex]10e^{-0.00043t[/tex], for t when R = 5 grams. We can do this using logarithms.
Set up the equation with R = 5: 5 = [tex]10e^{-0.00043t[/tex]
Divide both sides by 10 to isolate the exponential term: 0.5 = [tex]e^{-0.00043t[/tex]
Take the natural logarithm (ln) of both sides: ln(0.5) = ln([tex]e^{-0.00043t[/tex]), which simplifies to ln(0.5) = -0.00043t because the natural logarithm and the exponential function are inverses of each other.
Divide by -0.00043 to solve for t: t = ln(0.5) / -0.00043
Use a calculator to find the value of t: t ≈ 1608 years (rounded to the nearest whole year)
After approximately 1608 years, there will only be 5 grams of radium present in the container.

figure lmno is a rectangle. The slope of LM is -1/2. What are the slopes of MN and OL?
Answer:
The slopes of these other two segments would be 2.
Step-by-step explanation:
In order to find these slopes, you need to know that rectangles have right angles. Given this fact, we know these segments are perpendicular to the given segment. This means that we take the current slope (-1/2), we flip it, (-2) and negate it (2) to get the new slope.
4 1/4 divided by 1 1/2
Final answer:
The division of 4 1/4 by 1 1/2, when converted to improper fractions, results in 17/6, or 2 5/6 as a mixed number.
Explanation:
The question asks us to find the result of the division 4 1/4 divided by 1 1/2. To tackle this problem, we need to convert the mixed numbers into improper fractions and then perform the division by multiplying by the reciprocal. Here's how it is done step-by-step:
Convert mixed numbers to improper fractions:
4 1/4 = (4×4 + 1)/4 = 17/4 and
1 1/2 = (1×2 + 1)/2 = 3/2.
Divide the fractions by multiplying by the reciprocal of the divisor:
(17/4) × (2/3) = 34/12.
Simplify the result:
34/12 can be simplified to 17/6, or as a mixed number, 2 5/6.
Therefore, the answer to 4 1/4 divided by 1 1/2 is 2 5/6.

The veloctiy of sound in air is given by the equation v=20 times the square root of 273+t where v is the velocity in meters per second and t is the temperature in degrees Celcius. Find the temperature when the velocity of sound in air is 369 meters per second. Round to the nearest degree.
Answer:
The velocity of sound in air is 369 meters per second at 67 degrees Celcius.
Step-by-step explanation:
The veloctiy of sound in air is given by the equation
[tex]v=20\sqrt{273+t}[/tex]
where v is the velocity in meters per second and t is the temperature in degrees Celcius.
We need find the temperature when the velocity of sound in air is 369 meters per second.
Substitute v=369 in the give equation.
[tex]369=20\sqrt{273+t}[/tex]
Divide both sides by 20.
[tex]\frac{369}{20}=\sqrt{273+t}[/tex]
[tex]18.45=\sqrt{273+t}[/tex]
Taking square both the sides.
[tex](18.45)^2=273+t[/tex]
[tex]340.4025=273+t[/tex]
Subtract 273 from both the sides.
[tex]340.4025-273=t[/tex]
[tex]67.4025=t[/tex]
[tex]t\approx 67[/tex]
Therefore the velocity of sound in air is 369 meters per second at 67 degrees Celcius.

Select the measures that are equal
6 feet 15 yards 45 feet 600 inches 12 feet 640 inches
To solve such problems, we need to know about Units conversion.
Units conversionUnit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimeter is equal to 10 mm,
though the real measurement is still the same the units and numerical values have been changed.
Common Unit Conversion1 yard = 36 inches,
1 foot = 12 inches,
Given to us,
6 feet, 15 yards, 45 feet, 600 inches, 12 feet, 640 inches
Converting the units to inches,
1 foot = 12 inches,
6 feet = 6 x 12 = 72 inches,
45 feet = 45 x 12 = 540 inches,
12 feet = 12 x 12 = 144 inches,
1 yard = 36 inches,
15 yards = 15 x 36 = 540 inches,
As we can see above the value of 15 yards and 45 feet are equal to 540 inches, therefore, equal to each other.

A diagonal shortcut across a rectangular lot is 130 feet long. The lot is 50 feet long. What is the other dimension of the lot
The other dimension of the rectangular lot is 120 feet.
Explanation:In a rectangular lot, the diagonal forms a right triangle with the two sides of the rectangle. We can use the Pythagorean theorem to find the length of the other dimension of the lot.
Let's assume that the other dimension of the lot is x feet. The diagonal, which is 130 feet, is the hypotenuse of the right triangle. The two sides of the rectangle are 50 feet and x feet.
Using the Pythagorean theorem, we have:
x2 + 502 = 1302
x2 + 2500 = 16900
x2 = 14400
x = √14400 = 120
Therefore, the other dimension of the lot is 120 feet.

Of the 34 cars in a parking lot, 20 are green, 8 are gold, and the rest are black. What are the odds against the next car leaving the lot being black?
The odds against the next car leaving the parking lot being black are calculated by finding the number of black cars (6) and using the formula (Total cars - Black cars) : Black cars, which results in odds of 14:3.
To answer the question regarding the odds against the next car leaving the parking lot being black, we need to calculate the number of black cars and then the odds.
There are a total of 34 cars in the lot, with 20 green and 8 gold, so the rest are black.
To find the number of black cars, subtract the number of green and gold cars from the total:
34 (total cars) - 20 (green cars) - 8 (gold cars) = 6 (black cars).
The odds in favor of an event are the ratio of the probability of the event happening to the probability of it not happening. Therefore, the odds against an event are just the opposite -- the ratio of the probability of the event not happening to the probability of it happening.
To calculate the odds against picking a black car, we use this ratio:
Odds against a black car = (Total cars - Black cars) : Black cars
Odds against a black car = (34 - 6) : 6
Odds against a black car = 28 : 6
Odds against a black car = 14 : 3.
So, the odds against the next car leaving the lot being black are 14:3.
