Answer:
3Step-by-step explanation:
Given the function f(x) = (5x+1)/2
We are to find the inverse first as shown;
let y = f(x)
y = (5x+1)/2
Replace y with x
x = (5y+1)/2
Make y the subject of the formula;
2x = 5y+1
5y = 2x-1
y = (2x-1)/5
f^-1(x) = (2x-1)/5
f^-1(8) = 2(8)-1/5
f^-1(8) = 16-1/5
f^-1(8) = 15/5
f^-1(8) = 3
Hence the answer is 3

Leslie surveyed 80 students in her grade and found that 47 students had a dog of those students, 17 of them also had a cat. There were 24 students that had a cat, but not a dog. There were 9 students that did not have a cat or a dog. Move values to create a two-way table that shows the data from Leslie's survey.
A two–way table that shows data from Leslie's survey is presented as follows;
Dog. No dog Total
Cat. 17. 24. 41
No cat. 30. 9. 39
Total 47. 33. 80
How can the two–way table be completed?The given parameters are;
Number of students in the survey = 80Number that had a dog = 47Number that also had a cat = 17Number that have cats but no dogs = 24Number that have neither cats or dogs = 9Solution;
The number that have dogs and no cat = 47 - 17 = 30
Therefore, we have;
Dog and cat = 17
No dog and cat = 24
No dog no cat = 9
Total number that have cats = 17 + 24 = 41
Number that have no cats = 30 + 9 = 39
Sum total of students that have no dogs = 24 + 9 = 33
A two way table is presented as follows;
Dog. No dog Total
Cat. 17. 24. 41
No cat. 30. 9. 39

Anil Kumar took a loan of Rs. 20,000 from bank at the rate of 8% per annum. At the end of 2 years, how much compound amount should he pay if the interest was compounding half-yearly?
Anil Kumar should pay a compound amount of Rs. 23,397.12 at the end of 2 years.
Compound interest is a method of calculating interest where the interest earned is added to the principal amount, and the resulting sum becomes the new principal for the next period's interest calculation. This process is repeated until the end of the investment period.
The formula to calculate the compound interest is:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
Where,
A = Amount after the given time
P = Principal amount (initial investment)
r = Annual interest rate (as a decimal)
n = Number of times the interest is compounded per year
t = Time duration for which the interest is calculated (in years)
In this case, Anil Kumar took a loan of Rs. 20,000 from a bank at the rate of 8% per annum, compounded half-yearly, for 2 years. Therefore, we can plug in the values as follows:
P = Rs. 20,000
r = 8% per annum = 0.08 (as a decimal)
n = 2 (since the interest is compounded half-yearly)
t = 2 years
Now, we can calculate the compound amount using the above formula:
[tex]A = P(1 + r/n)^(^n^t^)[/tex]
[tex]A = 20,000(1 + 0.08/2)^(^4^)[/tex]
[tex]A = 20,000(1 + 0.04)^4[/tex]
[tex]A = 20,000(1.04)^4[/tex]
[tex]A = 23397.1712[/tex]
Therefore, Anil Kumar should pay a compound amount of Rs. 23,397.123 at the end of 2 years.

Graph a right triangle with the two points forming the hypotenuse.
Using the sides, find the distance between the two points in simplest
radical form. (8,7) and (6,3)
the distance between the points (8, 7) and (6, 3) which is the hypotenuse of the triangle is 2 √ 5 units.
We need to find the distance between two points which is the hypotenuse of the triangle:
(8, 7) and (6, 3)
It can be calculated using distance formula:
D = √ (x₂ - x₁)² + (y₂ - y₁)²
Substituting the values in the formula, we get that:
D = √ (6 - 8)² + (3 - 7)²
D = √ ( - 2 )² + ( - 4 )²
D = √ 4 + 16
D = √ 20
D = 2 √ 5 units
Therefore, we get that, the distance between the points (8, 7) and (6, 3) which is the hypotenuse of the triangle is 2 √ 5 units.

Answer:
y - 4 = -8/7(x - 4)
Step-by-step explanation:
Point-Slope form: y - y₁ = m(x - x₁)
x₁ and y₁ would be the coordinates of the point (4,4).
m would be the slope -8/7.
Substituting these values:
y - 4 = -8/7(x - 4)
Answer:

Solve for F
Solving for the variable 'f' gives f = 100 - 2h/5
What is subject of formula?A subject of formula can be defined as the variable that is expressed in terms of other variables in a given expression, function of equation.
It is the variable that is worked out in an equation and left to stand on its own on one side of the equality sign
Given the equation;
5f+2h = 100
To make 'f' the subject of formula, we take the following steps;
Take '2' over the equality sign
5f = 100 - 2h
Now, let's make 'f' the subject by dividing both sides by its coefficient which is 5
We have;
5f/5 = 100 - 2h/5
Divide through
f = 100 - 2h/5
Thus, solving for the variable 'f' gives f = 100 - 2h/5

Help me find the X! UwU..
Well all the angles in a triangle add up too 180º and this triangle is obviously a equilateral triangle (all sides are same) BUT as you see the other people saying X = 60º notice that it says 2 xº meaning that it is X x 2 so 60º is actually wrong :).
If it is X is 60º (since the 3 angles add together since it’s equilateral) then that would be 2 x 60º = 120º times 3 WHICH IS NOT 180.I think U get what I mean now,it’s 2 Xº; so X is 30 because 30 x 2 = 60º and 60 x 3 = 180º!
So Da Answer is X = 30º

A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 3200 seats. The students filled 2112 of the seats in the theater. What percentage of the seats in the theater were filled by the 6th graders on the trip?
The 6th graders filled 66% of the seats in the theater on the field trip.
To find the percentage of seats in the theater that were filled by the 6th graders on the field trip, we can use the following formula:
Percentage = (Filled Seats / Total Seats) * 100
Filled Seats = 2112
Total Seats = 3200
Substituting the values into the formula:
Percentage = (2112 / 3200) * 100
Percentage = 0.66 * 100
Percentage = 66%

The 6th-grade students filled approximately 66 percent of the 3200 seats in the theater during their field trip to see the ballet.
Use the concept of percentage defined as:
A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.
The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
Given that,
A middle school took its 6th-grade students on a field trip to see a ballet.
The field trip took place at a theater.
The theater has a total of 3200 seats.
The 6th-grade students filled 2112 of the seats in the theater.
To calculate the percentage of seats filled by the 6th-grade students:
Use the formula = (Number of seats filled / Total number of seats) x 100.
In this case,
The number of seats filled by the 6th-grade students is 2112, and the total number of seats in the theater is 3200.
Put the values, we get,
(2112 / 3200) x 100 = 66%
Hence
The 6th graders filled approximately 66% of the seats in the theater.

Answer:
∠6=116°
Step-by-step explanation:
Buckle up :)
We are given the values of ∠4 [tex](-2x+94)[/tex] and ∠8 [tex](-5x+139)[/tex].Vertical angles are congruent. Angle 4 and angle 1 are vertical angles, so angle 1 is also [tex]-2x+94[/tex].∠1 and ∠8 are alternate exterior angles. The transversal is the line that crosses over the parallel lines. When two angles are on opposite sides of the transversal, they are alternate angles. When the two angles are on the outside of the parallel lines, they are exterior angles. This makes them alternate-exterior angles.Alternate exterior angles are congruent. This means that ∠1≅∠8. Write an equation in order to solve for x:[tex]-2x+94=-5x+139[/tex]
Solve for x. Subtract 94 from both sides:
[tex]-2x+94-94=-5x+139-94\\\\-2x=-5x+45[/tex]
Add 5x to both sides:
[tex]-2x+5x=-5x+5x+45\\\\3x=45[/tex]
Divide both sides by 3:
[tex]\frac{3x}{3} =\frac{45}{3} \\\\x=15[/tex]
Insert the value of x into angle 4 because they are same-side interior angles. This is because they are on the same side of the transversal and within the parallel lines. Same-side interior angles are supplementary, so their value will add up to 180°. Therefore, in order to find angle 6, we need to first find the true value of angle 4:
[tex]x=15\\\\-2(15)+94\\\\-30+94\\\\64[/tex]
∠4 is 64°. Use ∠a+∠b=180 to find angle 6:
[tex]a+64=180[/tex]
a represents angle 6. Subtract 64 from both sides:
[tex]a+64-64=180-64\\\\a=116[/tex]
Angle 6 has a measure of 116°.

A right triangle has one leg with a length of 18 mm and a hypotenuse with a length of 82 mm.
What is the length of the other leg?
Your answer
Answer:
80 mm
Step-by-step explanation:
Pythagorean theorm can be applied here to solve for the length of the last leg, [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex], where (a) and (b) are the legs of the triangle and (c) is the hypotenuse. We can rearrange the pythagorean theorm for our purposes like the following:
b = √c^2 - √a^2
= √(82)^2 - √(18)^2
= √6724 - √324
= √6400
= 80 mm

Hello!
[tex]\large\boxed{k = 10^{o}}[/tex]
When given two interior angles and an exterior angle, the sum of the two interior angles is equal to the sum of the exterior angle. Therefore:
m∠YZX + m∠ZXY ≅ m∠MYZ
(4k + 5)° + (6k + 10)° = 115°
Combine like terms:
10k + 15 = 115°
Subtract 15 from both sides:
10k = 100°
Divide both sides by 10:
k = 10°
Answer:
k=10
Step-by-step explanation:
First you would find the missing angle at the top this would be 65 degrees, this means that the 2 other missing angles must total to 115 degrees.
Second you would set the equations equal to 115
4k+5+6k+10=115
Then you would combine the like terms
10k+15=115
next you would subtract the 15 from both sides
10k=100
then you divide by 10
k=10
