a) The inverse function is obtained by rearranging the variables for temperature and height in the given equation.
b) T⁻¹(x) =41-x/1.25
c) T⁻¹(30) =8.8
The given function is T(h)=41- 1.25h, so the inverse of a function is just obtained by rearranging the variables for height and temperature, the variable of temperature is replaced by height and vice versa. for the second
T(h)=41- 1.25h, considering h= x
=>T(x)=41- 1.25x
setting T(x)=x and x= T(x), we get
41- 1.25T(x) =x
=>1.25T(x) =x -41
=>T(x) =x- 41/ 1.25
now setting T(x)= T⁻¹ (x) we get : T⁻¹ (x) =41-x/1.25
For T⁻¹(30) =41-30/1.25= 11/1.25 =8.8

The sum of the measures of the angles of any triangle is 180 degrees . In a certain triangle, the largest angle measures 55degrees less than twice the medium angle, and the smallest angle measures 25 degrees less than the medium angle. Find the measures of each of the three angles.
Each of the three angles of the triangles whose sum of angles is 180 degree measures 75°, 65°, and 40°
What is meant by measurement of angles?An easy geometric instrument like a protractor is used to measure angles. A protractor is employed more frequently than a compass. Angle measurement is important for determining the precise angle. In geometry, there are several sorts of angles that we face in our daily lives, and we may measure angles using these tools.
Basic geometric instruments like a protractor and a compass are used to measure angles. These instruments aid in determining an angle's precise measurement. A protractor aids in producing an accurate angle measurement, while a compass aids in creating the angle. Angles can be measured in three different ways: in degrees, radians, and revolutions.
Here, we have
Let the largest angle be x degrees, the median y, and the smallest z.
x = 2y - 55
z = y - 25
x + y + z = 180
Substituting for x in the last equation:
2y - 55 + y + z = 180
3y + z = 235
From the second equation:
- y + z = -25 Subtract this from the last equation:
4y = 260
y = 65 degrees
z = 65 - 25 = 40 degrees.
and x = 180 - 65 - 40 = 75 degrees.

what is the ratio of the area of a square inscribed in a semicircle with radius $r$ to the area of a square inscribed in a circle with radius $r$? express your answer as a common fraction.
The ratio of the area of a square inscribed in a semicircle to the area of a square inscribed in a circle is 2/5.
What is a semicircle?
A semicircle in mathematics is a one-dimensional locus of points that makes up one-half of a circle. A semicircle's entire arc always measures 180 degrees. There is only one symmetry line in it.
For instance, if the radius is known, we can use the formula, which states that the area of a semicircle is equal to half that of a circle. As a circle's area is r2, Therefore, a semicircle's area is equal to 1/2(r2), where r is its radius. 3.14, or 22/7, is the value of.
Solution Explained:
Let's assume and take
The dimensions of the little square ABCD = 2 x 2 =4
of the little triangle's hypotenuse Radius of the semi-circle for BCG
H=sqrt(5) = The semicircle's radius
IHJK = 2sqrt is the diagonal of the huge square (5)
One side of the large square is IHJK when sin(45) x 2sqrt(5) = sqrt(10).
Therefore, the area of ABCD/area of IHJK is equal to 4/sqrt(10)2 = 2/5.

The measure of the angle RQP = 60 degrees and the value of x is 16 and the measure of the arc RMP is 240 degrees.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle).
It is given that:
A circle:
The measure of the arc RMP = 360 - Arc RP
The measure of the arc RMP = 360 - 120 = 240 degrees
The measure of the angle RQP = 1/2[240 - 120]
The measure of the angle RQP = 60 degrees
In the second circle:
9(9 + x) = 15(15)
9 + x = 25
After solving we get:
x = 16
Thus, the measure of the angle RQP = 60 degrees and the value of x is 16 and the measure of the arc RMP is 240 degrees.

suppose we play a game where we roll a six sided dice. if a 4,5 or 6 is rolled, i get 1 point if a 1,2,3 is rolled,you get 1 point. we play first to 5 but the winner must also win by 2. if we are tied at 5, what's the probability that you win the game?
The probability that you win the game is 50%.
The game is symmetrical for you and your opponent. Thus, your probability of winning is as good as your opponent's, so, you have a 50% of winning.
What does symmetric mean in probability?Symmetry goes into play in probability theory in this way: if different outcomes are equivalent, they would have the same probability.
A symmetrical distribution happens when the values of variables come at regular frequencies and usually the mean, median, and mode all happen at the same point.
In general, if there are N symmetrical outcomes, the probability of any given one of them happening is taken to be 1/N.

does the series converge? if the series does converge, find the sum. (if the quantity diverges, enter diverges.)
The given series [tex]\sum_{n=1}^{\infty}\left [ (0.3)^{n-1}-(0.2)^{n} \right ][/tex] is convergence and the sum of the series is 33/28.
In the given question we have to check whether the series converge or not. If the series does converge, then we have to find the sum.
The given series is [tex]\sum_{n=1}^{\infty}\left [ (0.3)^{n-1}-(0.2)^{n} \right ][/tex].
Firstly we check the convergence of the given series.
When a series approaches a limit, it is considered to be convergent if both convergent and divergent behaviour occur. The deletion of a finite number of terms from the beginning of a series has no impact on convergence or divergence.
We can write the series as:
[tex]\sum_{n=1}^{\infty}\left [ (0.3)^{n-1}-(0.2)^{n} \right ]=\sum_{n=1}^{\infty} (0.3)^{n-1}-\sum_{n=1}^{\infty}(0.2)^{n} \right[/tex]
As |0.3|<1 and |0.2|<1
Then [tex]\sum_{n=1}^{\infty}(0.3)^{n-1}\text{ and }\sum_{n=1}^{\infty}(0.2)^n[/tex] is convergent.
So [tex]\sum_{n=1}^{\infty} (0.3)^{n-1}-\sum_{n=1}^{\infty}(0.2)^{n} \right[/tex] is also convergent.
[tex]\sum_{n=1}^{\infty}\left [ (0.3)^{n-1}-(0.2)^{n} \right ]=\sum_{n=1}^{\infty} (0.3)^{n-1}-(0.2)\sum_{n=1}^{\infty}(0.2)^{n-1} \right[/tex]
Series [tex]\sum_{n=1}^{\infty}(x)^{n-1}[/tex] converges to 1/x-1 for |x|<1.
[tex]\sum_{n=1}^{\infty}\left [ (0.3)^{n-1}-(0.2)^{n} \right ]=\frac{1}{1-0.3}-(0.2)\frac{1}{1-0.2}[/tex]
[tex]\sum_{n=1}^{\infty}\left [ (0.3)^{n-1}-(0.2)^{n} \right ]=\frac{1}{0.7}-\frac{0.2}{0.8}[/tex]
[tex]\sum_{n=1}^{\infty}\left [ (0.3)^{n-1}-(0.2)^{n} \right ][/tex] = 10/7 - 1/4
[tex]\sum_{n=1}^{\infty}\left [ (0.3)^{n-1}-(0.2)^{n} \right ][/tex] = 33/28

Line a passes through the points (−5, −2) and (−5, −5), while line b passes through (0, 4) and (5, 4).
Which statement best describes the relationship between lines a and b?
A. a and b are intersecting.
B. a and b are parallel.
C. a and b are collinear.
D. a and b are perpendicular.
Based on the slopes of both lines, the relationship between both lines is: D. a and b are perpendicular.
What is the Relationship between Parallel lines or Perpendicular Lines?The relationship between two lines that are parallel is that they have the same slope, while the relationship between perpendicular lines is that their slopes are negative reciprocals of each other.
Find the slope of the line that passes through (-5, -2) and (-5, -5):
Slope (m) = change in y / change in x = (-5 -(-2)) / (-5 -(-5))
m = (-5 + 2) / (-5 + 5)
m = -3/0 [cannot divide, therefore, the slope is undefined).
The line is therefore a vertical line.
Find the slope of the line that passes through (0, 4) and (5, 4):
Slope (m) = change in y / change in x = (4 - 4) / (5 - 0)
m = 0/5
m = 0
This line is an horizontal line.
In conclusion, the relationship between a vertical and a horizontal line is that they are perpendicular to each other, therefore, the answer is: D. a and b are perpendicular.

The value of the side c which is the hypotenuse of the given right angle triangle using Pythagoras theorem is; c = √148
How to use Pythagoras Theorem?
Pythagoras Theorem is simply the way that we can find the missing length of a right angled triangle. The right angle triangle has three sides, namely the hypotenuse (which is the longest side), Opposite (which does not touch the hypotenuse) and then the adjacent side (which is between the opposite side and the hypotenuse).
The formula is literally;
c² = a² + b²
where;
c is hypotenuse and a and b are opposite and adjacent sides. Thus;
c² = 2² + 12²
c² = 4 + 144
c² = 148

If staff salaries were $44,000/month last year and $53,000/month this year, what is the approximate labor cost increase in percentage?.
Given that the pay was $44,000 last year and $53,000 this year, the compensation will have increased by 20.45%.
What is percent?In essence, percentages are fractions with a 100 as the denominator. We place the percent sign (%) next to the number to indicate that the number is a percentage. For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100). Percentage is defined as "out of 100." Similar to fractions and decimals, percentages are used in mathematics to represent subsets of a whole. When expressing a sum as a percentage, 100 equal parts are considered to make up the whole.
Here,
Salary of staff last year=$44,000
Salary of staff this year=$53,000
The percent increase,
=(53000-44000)/44000*100
=20.45%
The percent increase in the salary will be 20.45% as the salary last year was $44,000 and the salary this year is $53,000.

The number of files sorted in the first one and a half hours of sorting is 945.
Here, we are given that a group of clerks must sort 1775 files.
Each clerk sorts at a constant rate of 30 files per hour.
Let the number of clerks who start working initially be x.
Thus, they will sort 30x files in the first hour.
After the first hour, let the number of clerks who stop working be a
Thus, the number of files sorted in the second hour will be 30(x - a)
Similarly, the number of files sorted in the third hour will be 30(x - 2a)x
In the last 10 minutes, the number of files sorted will be 5(x - 3a)
Thus, we can form the following equation-
30x + 30(x - a) + 30(x - 2a) + 5(x - 3a) = 1775
30x + 30x - 30a + 30x - 60a + 5x - 15a = 1775
95x - 105a = 1775
19x - 21a = 355
x = (355 + 21a)/ 19
since x and a both have to be integers, (355 + 21a) must be divisible by 19.
This is the case when a = 3
⇒ x = (355 + 21*3)/ 19
x = 418/ 9
x = 22
Now, the number of files sorted in first one and a half hours will be-
30x + 15(x - a)
= 30*22 + 15(22 - 3)
= 660 + 15*19

A Norman window is a rectangle with a semicircle on top. Suppose that the perimeter of a particular Norman window is to be 19 feet. What should the rectangle's dimensions be in order to maximize the area of the window and, therefore, allow in as much light as possible? (Round your answers to two decimal places.)
The dimensions of the rectangle that will maximize the area of the window are length, L = 3.41 feet and width, w = 3.41 feet
What rectangle dimensions will maximize the area of the window?
Given: Perimeter (P) = 19 feet
Perimeter of window = Perimeter of rectangle + Perimeter of semicircle
P = 2(2r + L) + πr
where r = radius of the semicircle and L = length of the rectangle
width(w) of the rectangle = 2r
Note: the diameter of the semicircle is the width of the rectangle
19 = 2(2r + L) + πr
19 = 4r + 2L + πr
2L = 19-4r-πr
L = 19/2 -2r- πr/2
Find the area (A) of the window:
A = Area of Rectangle + Area of Semicircle
A = 2rL + 1/2πr²
Put L into A = 2rL + 1/2πr²:
A = 2r(19/2 -2r- πr/2) + 1/2πr²
A = 19r - 4r² - πr² + 1/2πr²
A = 19r - 4r² - 1/2πr²
To maximize the area, differentiate both sides and set A' = 0
A = 19r - 4r² - 1/2πr²
A' = 19 - 8r - πr
0 = 19 - 8r - πr
8r + πr = 19
r(8 + π) = 19
r = 25/(8 + π)
width(w) = 2r
w = 2[19/(8 + π)]
w = 38/(8 + π)
w = 3.41 feet
put r = 19/(8 + π) into L = 25/2 -2r- πr/2:
L = 19/2 -2(19/(8 + π))- π(19/(8 + π))/2
L = 19/2 - 38/(8 + π) - 19π/2(8 + π)
L = [19(8 + π) - 19(2)- 19π] / [2(8 + π)]
L = 38/(8 + π)
L = 3.41 feet
Therefore, the dimensions of the rectangle are length of 3.41 feet and width of 3.41 feet

[tex]\mathrm{A = P(1 + r/n)^{(nt)}}[/tex]
Where:
A is equal to the final sum, in this case $480.
P is the principal sum, which represents the initial investment that we're looking for.
r = the yearly interest rate (0.055 in decimal form, or 5.5%)
n = the number of times the interest is compounded annually (in this case, n = 1 because it is compounded annually).
t = the number of years, in this instance 8 years.
Let's substitute the known values into the formula and solve for P:
[tex]\mathrm{480 = P(1 + 0.055/1)^{(1\times8)}}[/tex]
Simplifying:
[tex]480 = \mathrm P(1.055)^8[/tex]
Dividing both sides by (1.055)⁸:
[tex]\mathrm {P = \frac{480 }{ (1.055)^8}}[/tex]
P ≈ $480 / 1.50
P ≈ $320
Hence the amount to be invested is $320.

How many weeks will it take Lian's dog to finish this remaining food? .
weeks
It will take Lian's dog 12.5 weeks to finish the remaining food
How to determine how many weeks will it take Lian's dog to finish the remaining food?Fractions are numbers written as a quotient, in which a numerator is divided by a denominator
Given that:
Lian's dog eats 1/20 of a bag of dog food each week
Lian currently has of a bag 5/8 remaining
Since Lian's dog eats 1/20 in one week and 5/8 is remaining.
In order to find the number of weeks it will take the dog to finish the remaining food. We can say:
Number of weeks = remaining food / food for one week
Number of weeks = (5/8) / (1/20) = 12.5 weeks
Therefore, it will take Lian's dog 12.5 weeks to finish the remaining food

mary spent a total of $322.58 for a party. she spent $200.14 on food, plus an additional $30.61 for each hour of the party. how long was the party?
Answer: 4 hours
Step-by-step explanation:
322.58 - 200.14 = 122.44
122.44 divided by 30.61 = 4
a person stands on a scale in an elevator. as the elevator starts, the scale has a constant reading of 590 n. as the elevator later stops, the scale reading is 386 n. assume the magnitude of the acceleration is the same during starting and stopping.
Assuming the person's weight and magnitude, we can estimate their weight to be 491N.
What do we mean by magnitude?A mathematical object's magnitude or size defines whether it is greater or smaller than other items of its kind.
In formal terms, an object's size can be thought of as the outward manifestation of an ordering—of the class of objects to which it belongs.
So, the person's weight will be:
The scale calculates the floor's usual upward force on the passenger.
The most force is produced when going up (when starting an upward trip or ending a downward trip).
The normal force is lowest when there is a downward acceleration.
Regarding any such situation
∑F y =ma y changes to +391Nmg = ma for halting and +591Nmg=+ma for starting. (Where a represents the size of the acceleration.)
Add these two simultaneous equations to eliminate a and determine mg:
+591N−mg+391N−mg=0
OR
982N–2mg=0
Fg = mg = 982N/2 = 491N
Therefore, assuming the person's weight and magnitude, we can estimate their weight to be 491N.

what is the answer i need answers now
Answer:
The answer is third one, 6 and 7/20.
Step-by-step explanation:
First, rewrite the decimal number as a fraction with 1 as the denominator.
[tex]\frac{6.35}{1}[/tex]
Then, multiply to remove 2 decimal places.
[tex]\frac{6.35}{1} *\frac{100}{100} = \frac{635}{100}[/tex]
Next, find the GCF(Greatest common factor) of 635 and 100, which is 5.
Divide both the numerator (top) and denominator (bottom) by the GCF (5)
Simply the improper fraction.
There you go!
