Answer:
1. What is the maximum length of a chess table that is still within the tolerance limit?
To find the maximum length of a chess table that is still within the tolerance limit, we add the tolerance to the average length:
110 cm + 16.5 cm = 126.5 cm
Therefore, the maximum length of a chess table that is still within the tolerance limit is 126.5 cm.
2. What is the minimum length of a chess table that is still within the tolerance limit?
To find the minimum length of a chess table that is still within the tolerance limit, we subtract the tolerance from the average length:
110 cm - 16.5 cm = 93.5 cm
Therefore, the minimum length of a chess table that is still within the tolerance limit is 93.5 cm.

What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Given that, a high school sports team is ordering sports drinks online from a company.
Let the amount of drinks be y and number of drinks be x.
For drink not more than 50.
y=10+0.8x ------(i)
For drinks more than 50
y=15+0.7x ------(ii)
For a purchase of $75, it means that:
y=75
Substitute y=75 in equation (i), we get
y=10+0.8x
75=10+0.8x
0.8x=75-10
0.8x=65
x= 65/0.8
= 81.25
x=81
Substitute y=75 in equation (ii), we get
y=15+0.7x
75=15+0.7x
0.7x=60
x=85.7
x=84
By comparing both values
x=84 and x=81
84>81
Hence, the maximum amount that can be purchased is 84.

Find the exact values of sin(2u), cos(2u), and tan(2u) using the double-angle formulas. csc(u) = 3, 0 < u < /2
By answering the supplied question, we may infer that the response is trigonometry Cos(2u) = -7/9, Sin(2u) = 4sqrt(2)/9, and Tan(2u) = 3/4.
what is trigonometry?The area of mathematics called trigonometry examines how triangle side lengths and angles relate to one another. The subject first came to light in the Hellenistic era, about in the third century BC, as a result of the use of geometry in astronomical investigations. The area of mathematics known as exact techniques deals with several trigonometric functions and possible computations using them. There are six common trigonometric functions in trigonometry. These go by the designations sine, cosine, tangent, cotangent, secant, and cosecant, respectively (csc). The study of triangle characteristics, particularly those of right triangles, is known as trigonometry. Consequently, studying geometry entails learning about the characteristics of all geometric forms.
The values of sin(2u), cos(2u), and tan(2u) in terms of the given value of u may be determined using the double-angle formulae.
The formulae for double angles are as follows:
[tex]2sin = sin(2u) (u)[/tex]
cos(u)
(2u) = cos(2u)
The formula is 2(u) - sin(u) tan(2u) = (2tan(u)) / (1-tan(u)).
We may use the definition of csc(u) to obtain sin(u) given that csc(u) = 3 and 0 u /2:
[tex]sin(u) = 3 sin(u) = 1/3 csc(u) = 1/sin(u)[/tex]
Now we can calculate sin(2u), cos(2u), and tan(2u) using the double-angle formulas:
[tex]2sin = sin(2u) (u)[/tex]
sqrt(1 - sin2(u)) = 2/3 sqrt(8/9) = 4sqrt(2)/9 cos(u) = 2(1/3)
[tex]cos(2u) = sin - cos2(u)[/tex]
2(u) = (1 - sin 2(u)) sqrt
[tex]a^2 - sin^2(u) = 1/9 - 8/9 = -7/9[/tex]
[tex]tan(2u) = (2tan(u)) / (1-tan(2u)) = (2(1/3)) / (1-(1/3)2) = 6/8 = 3/4[/tex]
Cos(2u) = -7/9, Sin(2u) = 4sqrt(2)/9, and Tan(2u) = 3/4.

Austin is 6 years older than Roya. In 3 years the sum of their ages will be 54 . How old is Austin now?
Austin is currently 27 years old.
Explanation:
To find out how old Austin is now, we need to use algebra. Let's start by assigning variables to represent their ages. Let A be Austin's current age and R be Roya's current age.
According to the question, we know that:
A = R + 6 (since Austin is 6 years older than Roya)
In 3 years, their ages will be:
A + 3 (for Austin)
R + 3 (for Roya)
And the sum of their ages in 3 years will be 54:
A + 3 + R + 3 = 54
Simplifying the equation gives us:
A + R = 48
Substituting the first equation into the second equation gives us:
R + 6 + R = 48
Combining like terms gives us:
2R = 42
Dividing both sides by 2 gives us:
R = 21
Now that we know Roya's current age, we can use the first equation to find Austin's current age:
A = R + 6
A = 21 + 6
A = 27

In the given triangle of attached figure , the required value of x and y is given by option d. x=24.0,y=46.4 ( nearest tenth ).
Let us consider triangle name of the attached figure be ABC,
From vertex A perpendicular line intersect BC at point D.
From the attached figure,
Measure of ∠B = 45°
Measure of ∠C = 30°
Side length AC = 34 units
Side length AB = x units
Side length BC = y units
In triangle ADC,
sin C = AD / AC
Substitute the value we have,
⇒ sin 30° = AD / 34
⇒ AD = ( 1/2 )× 34
⇒ AD = 17
And cos C = CD / AC
Substitute the value we have,
⇒ cos 30° = CD / 34
⇒CD = 34 × cos 30°
⇒ CD = 34 × (√3 /2 )
⇒ CD = 29.45 units
In triangle ADB,
sin B = AD/ AB
⇒ sin 45° = 17 / x
⇒ x = 17 / sin 45°
⇒ x = 17 / ( 1/√2)
⇒ x = 17√2
⇒ x= 24.038 units
⇒ x= 24.0 units ( nearest tenth )
Now in triangle ABD,
cos B = BD/ AB
⇒ cos 45° = BD / 24.0
⇒ BD = 24 × cos 45°
⇒ BD = 24× (1/√2)
⇒ BD = 16.97units
y = BD + CD
= 16.97 + 29.45
= 46.42
= 46.4 units ( nearest tenth )

let ABC be a triangle. Determine the exact values of
the three angles A, B, C. if we know that A = 5x, B = 6x, and C =
7x
For the given triangle ABC, the exact values of the three angles are: A = 50°, B = 60°, and C = 70°.
Let ABC be a triangle. The angles A, B, and C can be determined using the fact that the sum of the angles in any triangle is 180°.
We know that
A = 5x, B = 6x, and C = 7x, so:
A + B + C = 5x + 6x + 7x = 18x
Since the sum of the angles in a triangle is 180°, we can set
18x = 180°
and solve for x:
18x = 180°, x = 10°

A particles average speed is modeled by the equation
s(t)=T^2-6T+35, determine the average rate of the speeds increase
or decrease from t=2 to t=5
To determine the average rate of the speed's increase or decrease from t=2 to t=5, we need to find the slope of the line connecting the points (2,s(2)) and (5,s(5)) on the graph of the equation s(t)=T^2-6T+35. The slope of a line is given by the formula:
slope = (y2-y1)/(x2-x1)
In this case, x1=2, x2=5, y1=s(2), and y2=s(5).
Plugging in the values of x1 and x2 into the equation s(t)=T^2-6T+35, we get:
y1=s(2)=2^2-6(2)+35=4-12+35=27
y2=s(5)=5^2-6(5)+35=25-30+35=30
Now we can plug in the values of x1, x2, y1, and y2 into the slope formula:
slope = (30-27)/(5-2) = 3/3 = 1
Therefore, the average rate of the speed's increase or decrease from t=2 to t=5 is 1. This means that the speed is increasing at a constant rate of 1 unit per unit of time from t=2 to t=5.

a) Yes, I am skeptical of my friend's claim. The mean score of the class is 80, which means that the average score of all the students is 80.
b) I am also skeptical of my friend's claim that Class 2022 did better than Class 2023 in the Final Test. While the mean score of Class 2022 is higher than the mean score of Class 2023, this does not necessarily mean that Class 2022 did better.
If 50% of the students had a score higher than 80, then the other 50% of the students would have to have a score lower than 80 in order for the mean to be 80. However, my friend's estimation error of 0.07 means that there is a possibility that the true percentage of students with a score higher than 80 is actually between 43% and 57%. Therefore, it is not certain that 50% of the students had a score higher than 80.
It is possible that the distribution of scores for Class 2022 is more spread out, with some students scoring very high and some students scoring very low, while the distribution of scores for Class 2023 is more consistent.

The accumulated value is $A = 5000 \times e^{(0.09 \times 4)} = 7,311.12$.
The accumulated value of an investment of $\$ 5,000$ at 9% compounded continuously for 4 years is $7,311.12.
This can be calculated using the compound interest formula
\(A=P e^{\lambda t}\).
In this equation, A is the accumulated value of the investment, P is the principal investment amount (which is $\$ 5,000$), $\lambda$ is the interest rate per compounding period (which is 0.09) and t is the number of compounding periods (which is 4 years).
Therefore, the accumulated value is $A = 5000 \times e^{(0.09 \times 4)} = 7,311.12$.

1.Conversion a mixed number 5 7/8
to an improper fraction: 5 7/8 = 5 7/8
= 5 · 8 + 7/8
= 40 + 7/8
= 47/8
To find a new numerator:
a) Multiply the whole number 5 by the denominator 8. Whole number 5 equally 5 * 8/8 = 40/8
b) Add the answer from the previous step 40 to the numerator 7. New numerator is 40 + 7 = 47
c) Write a previous answer (new numerator 47) over the denominator 8.
Five and seven-eighths is forty-seven eighths.
2. Conversion a mixed number 4 1/3
to an improper fraction: 4 1/3 = 4 1/3 = 4 · 3 + 1/3 = 12 + 1/3 = 13/3
To find a new numerator:
a) Multiply the whole number 4 by the denominator 3. Whole number 4 equally 4 * 3/3 = 12/3
b) Add the answer from the previous step 12 to the numerator 1. New numerator is 12 + 1 = 13
c) Write a previous answer (new numerator 13) over the denominator 3.
Four and one-third are thirteen-thirds.
3. Add: 47/8
+ 13/3
= 47 · 3/8 · 3
+ 13 · 8/3 · 8
= 141/24
+ 104/24
= 141 + 104/24
= 245/24
It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - is LCM(8, 3) = 24. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 3 = 24. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - forty-seven eighths plus thirteen-thirds is two hundred forty-five twenty-fourths.
4. Conversion a mixed number 7 5/6
to an improper fraction: 7 5/6 = 7 5/6 = 7 · 6 + 5/6 = 42 + 5/6= 47/6
To find a new numerator:
a) Multiply the whole number 7 by the denominator 6. Whole number 7 equally 7 * 6/6= 42/6
b) Add the answer from the previous step 42 to the numerator 5. New numerator is 42 + 5 = 47
c) Write a previous answer (new numerator 47) over the denominator 6.
Seven and five-sixths are forty-seven-sixths.
5.Add: the result of step No. 3 + 47/6= 245/24 + 47/6 = 245/24 + 47 · 4/6 · 4 = 245/24 + 188/24 = 245 + 188/24 = 433/24
It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - is LCM(24, 6) = 24. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 24 × 6 = 144. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - two hundred forty-five twenty-fourths plus forty-seven sixths are four hundred thirty-three twenty-fourths.

Answer:
429 m³
Step-by-step explanation:
The volume of right rectangular = Length x Width x Height
The volume of right rectangular prism = 12 x 5 1/2 x 6 1/2
= 12 x 11/2 x 13/2
= 3 x 11 x 13
= 429 m³

Length of the side of square is x = 5.7 unit
What is Pythagoras theorem?The Pythagorean theorem states, "In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two sides." The sides of this triangle were called the perpendicular, the base and the hypotenuse. Here, the hypotenuse is on the opposite side of the 90° angle, so it is the longest side.
Given,
Figure of a rectangle and a right triangle share its hypotenuse with length of rectangle
diagonal of rectangle = 8
length of both sides of right triangle other than hypotenuse = 4
Let length of rectangle be l
By Pythagoras theorem
l² = 4² + 4²
l² = 32
l = 4√2
Now, In the rectangle
8² = l² + x²
64 = 32 + x²
x² = 32
x = 4√2
x = 5.7
rectangle is an square.
Hence value of x, length of the side of square is 5.7 unit.
