figure lmno is a rectangle. The slope of LM is -1/2. What are the slopes of MN and OL?
Answers
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.
Locate the prepositional phrase and type it in the blank. Then, identify the function of the phrase. Above the door hung a horseshoe. prepositional phrase: function of phrase: (Type adjective or adverb ).
Answers
The function of this prepositional phrase is adverbial, specifically it acts as an adverbial phrase of place, modifying the verb "hung". It answers the question "where?" in relation to the action of hanging.
The prepositional phrase in the sentence "Above the door hung a horseshoe" is "above the door".
This phrase describes the location of the horseshoe relative to the door. It specifies that the horseshoe is positioned vertically higher than the door. Prepositional phrases function as adjectives or adverbs by providing additional information about nouns (in this case, "door") or verbs (in this case, "hung"). In this context, "above the door" modifies the action of "hung" by indicating where the horseshoe is located.

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
Answers
then, x = [tex] \sqrt{14400} [/tex] = 120 feet has 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.

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,

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.
Answers
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.

4 1/4 divided by 1 1/2
Answers
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.

3h/h^2-12h+36 -18/h^2-12h+36
Answers
[tex] \frac{3h}{h^2-12h+36} - \frac{18}{h^2-12h+36} = \frac{3h-18}{h^2-12h+36} [/tex]
Notice that we have a common factor, 3, in the numerator, so lets factor that out:
[tex]\frac{3h-18}{h^2-12h+36}= \frac{3(h-6)}{h^2-12h+36} [/tex]
Next, we can factor the denominator:
[tex]\frac{3(h-6)}{h^2-12h+36} = \frac{3(h-6)}{(h-6)^2} [/tex]
Now we can cancel the common factor [tex]h-6[/tex] in both numerator and denominator:
[tex]\frac{3(h-6)}{(h-6)^2}= \frac{3}{h-6} [/tex]
We can conclude that the result of 3h/h^2-12h+36 -18/h^2-12h+36 is: [tex] \frac{3}{h-6} [/tex]
3h/h^2-12h+36- 18/h^2-12h+36=3h-18/h^2-12h+36
Let us factor the common termsx(h-6)/h^2-12h+36= 3(h-6)/(h-6)^2
So since h-6 are similar, we can cancel the numerator and cancel 1 term in the denominatorso,3(h-6)/(h-6)^2=3/h-6
SO the answer of 3h/h^2-12h+36 -18/h^2-12h+36 is 3/h-6

Answers
[tex]v = 20 \sqrt{273 + t} [/tex]
we are given v is 369 so we have

now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
[tex]369 = 20 \sqrt{273 + x} \\ 18.45 = \sqrt{273 + x} \\ 340.40 = 273 + x \\ x = 67.4[/tex]

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]

Which set is more variable? How do you know?
Please please help me ASAP like RIGHT NOW this is my last question and the only question I have left so please help me super quick!!!!!!!!!!
Answers
To determine which set is more variable, calculate their measures of variability such as range and standard deviation. Sets with larger range and standard deviation are considered more variable.
Explanation:To determine which set is more variable, you need to calculate the measures of variability for both sets. The measures of variability commonly used are the range and standard deviation. The set with a larger range and standard deviation is considered to be more variable.
For example, if we have two sets of data: Set A (2, 4, 6, 8, 10) and Set B (3, 5, 7, 9, 11), we can calculate the range for both sets. The range of Set A is 10 - 2 = 8, while the range of Set B is 11 - 3 = 8. Both sets have the same range, so we need to calculate the standard deviation to determine which set is more variable.
By calculating the standard deviation, we find that Set A has a standard deviation of 2.83, while Set B has a standard deviation of 2.83 as well. Again, both sets have the same standard deviation, so in this example, both sets are equally variable.
