please answer soon will give brainiest if correct.
AC:PC.= 3/5, as Line l ∥ AB and passes through point M to intersect diagonal AC and leg BC at points P and N.
What is Trapezoid?A trapezoid, commonly referred to as a trapezium, is a quadrilateral or a polygon with four sides. It has a set of parallel opposing sides and a set of non-parallel sides.
The bases and legs of the trapezoid are known as the parallel and non-parallel sides, respectively.
A trapezoid is a closed, four-sided, two-dimensional figure that has both a perimeter and an area.
The bases of the trapezoid are the two sides of the shape that are parallel to one another. The legs or lateral sides of a trapezoid are the non-parallel sides. The altitude is the shortest distance between two parallel sides.
According to our question-
Consider about the triangles ACB and PCN.
These triangles contain
Since angle C is the common angle and the transversal BC cuts two parallel lines PN and AB, angles ABC and PCN are congruent as equivalent angles by virtue of the reflexive property.
In light of the AA Similarity Theorem, triangles ACB and PCN are comparable.
Similar triangles have matching sides that are proportionate, thus
3/8 / 5/8= 3/5
Hence, Due to the fact that Line l AB and goes via point M to intersect Leg BC and the diagonal AC at points P and N, AC:PC.= 3/5.

b. Describe what this ratio tells you.
The region with the most rainfall is Beaumont, and the region with the least is El Paso.
How can I find the locations with the most and least rainfall?
Making sure to utilize the same units is the first step. Let's convert everything to meters as a result.
Austin equals 0.8687 m
Beaumont = 1.534 meters.
Galveston = 1,095 meters
El Paso equals 0.246 m

Subtracting a number is the same as adding its additive inverse. For which elevation do we need to find the additive inverse? What is the additive inverse of that elevation?
Yes subtracting a number is the same as adding its inverse. We have to find the additive inverse of a function.
What is additive inverse?The additive inverse of a number is the number which when we add to the number results zero.
How to find additive inverse?Complex numbers are made up of both real and fictitious numbers. A + iB, where A is the real number and B is the imaginary number, is a complex number.
The additive inverse of A + iB should now be a value that, when added to a given complex number, produces the result zero. It will therefore be -(A + iB).
Suppose we have to find additive inverse of 5.
Let the additive inverse of 5 be x.
So,5+x=0
x=-5
So the additive inverse of 5 is -5.
Hence to find additive inverse of a positive number we have to just put a negative mark and for a negative number we have put positive mark in front of the number.

If I want to invest my money and turn it into $900 over the course of two and a half years at the rate of 3.5%, how much money will I need to invest?
To turn $900 into $900 over the course of two and a half years at the rate of 3.5%, we can use the following formula:
Copy code
investment = (900 * (1 + 0.035)) ^ (2.5 / 1)
In this formula, investment represents the amount of money you need to invest, 900 represents the final amount you want to end up with, 0.035 represents the interest rate of 3.5%, 2.5 represents the number of years you want to invest for, and 1 represents the number of times per year that the interest is compounded.
Plugging in the values from the problem into the formula, we get:
Copy code
investment = (900 * (1 + 0.035)) ^ (2.5 / 1)
investment = ($900 * 1.035) ^ (2.5 / 1)
investment = $931.75 ^ 2.5
investment = $1434.24
Therefore, to turn $900 into $900 over the course of two and a half years at the rate of 3.5%, you will need to invest $1434.24.

Answer:
A:) T(t) = 305(230/305)^(t/10) +70
B:) T(20) ≈ 243.4 °F
Step-by-step explanation:
You have a pie removed from a 375° oven to a room temperature of 70° that has cooled to 300° after 10 minutes. You want to know its temperature after 20 minutes.
Law of CoolingNewton's law of cooling tells you the rate of change of an object's temperature is proportional to the difference between the object's temperature and that of its surroundings. The differential equation describing this has an exponential function as its solution. That exponential function can be written as ...
temperature = (initial temperature difference)·(cooling factor)^(time/(cooling time)) + (final temperature)
ApplicationHere, the initial temperature difference between the pie and room temperature is ...
initial temperature difference = 375° -70° = 305°
The final temperature is the room temperature:
final temperature = 70°
The cooling factor is the multiplier applied to the temperature difference in the time period "cooling time". Here, the pie is at 300°, a temperature difference of 300° -70° = 230° after a cooling time of 10 minutes. The cooling factor is ...
cooling factor = 230/305
A:) EquationThese values let us write the equation as ...
T(t) = 305(230/305)^(t/10) +70
B:) 20 minutesThe temperature after 20 minutes is found using this equation:
T(20) = 305(230/305)^(20/10) +70 = 305(46/61)^2 +70 = 243 27/61
T(20) ≈ 243.4 . . . . degrees F
__
Additional comment
The cooling factor can be expressed as a value that lets the exponent be t. Often, it is written as (e^k), where ...
k = 1/10·ln(230/305) ≈ -0.0282232
Then the equation is ...
T(t) = 305·e^(-0.0282232t) +70
It could also be written as ...
T(t) = 305(0.972171^t) +70
where 0.972171 = (46/61)^(1/10).

Remove the parentheses:
[tex]11-9 \dfrac{3}{5}y+8 \dfrac{9}{20}y-7[/tex]
Collect like terms:
[tex]8 \dfrac{9}{20}y-9 \dfrac{3}{5}y+11-7[/tex]
Subtract the numbers 11 - 7:

Factor out y:
[tex]\left(8 \dfrac{9}{20}-9 \dfrac{3}{5}\right)y+4[/tex]
Partition the mixed numbers into fractions and whole numbers, and then subtract them separately.
Subtract the whole numbers:
[tex]\implies 8-9=-1[/tex]
Subtract the fractions by changing both fractions into equivalent fractions so both fractions have the same denominator:
[tex]\implies \dfrac{9}{20}-\dfrac{3}{5}[/tex]
[tex]\implies \dfrac{9}{20}-\dfrac{3 \cdot 4}{5 \cdot 4}[/tex]

Find the equation of the line shown
Answer:
y = -x - 4
Step-by-step explanation:
y = mx + b is slope intercept form,
where m is the slope, and b is the y-intercept.
As we can see from the picture, the line has a negative slope of 1 (we can also just say -1). We know this is the slope because it has a rise of -1 and a run of -1. (I hope that made sense lol :/)
[Side note, we use x instead of 1.]
The y-intercept is -4 since we can see the line passes through the y-axis at -4.
Therefore, the equation can be written as y = -x - 4

Therefore we can rewrite the formula in terms of h you need to:
=> h = [tex]\frac{3V}{s^{2} }[/tex]
You must substitute these numbers into the following formula to determine the height of a square pyramid with volume V = 400 and side lengths s = 10 cm:
=> h = 3 * 400 / [tex]10^{2}[/tex]
=> 3* 400/100
=> 3*4
=> 12
Therefore , the height of the given square pyramid is 12 cm.
