The solution to this inequality is x >= 58. This means that Latanya should buy at least 58 sets of glasses in order to have at least 739 glasses.
What is the inequality equation?
Equations and inequalities are mathematical sentences formed by relating two expressions to each other. In an equation, the two expressions are supposed to be equal and shown by the symbol =. Whereas in inequality, the two expressions are not necessarily equal and are indicated by the symbols: >, <, ≤, or ≥.
To determine the minimum number of sets of glasses that Latanya should buy, we can set up the following inequality:
x * 6 + 390 >= 739
This inequality states that the number of glasses Latanya has after buying x sets of glasses should be greater than or equal to the minimum number of glasses the restaurant needs.
To solve for x, we can subtract 390 from both sides of the inequality to get:
x * 6 >= 739 - 390
x * 6 >= 349
x >= 349/6
x >= 58.16
x >= 58
Hence, The solution to this inequality is x >= 58. This means that Latanya should buy at least 58 sets of glasses in order to have at least 739 glasses.

if a lawyer charges 120 an hour(or any fraction of an hour) how much is a mill for 3 hours and 20 minutes?
If a lawyer charges 120 an hour then the bill for 3 hours and 20 minutes will be 400
Bill: A bill is the printed or written statement of the money owed for goods or services.In later Latin, bulla became billa, and in English billa became bill. The word can still refer to various official documents, such as a proposed law that is brought before parliament, although it is now most commonly used for documents that request payment of money.
One hour = 60 minutes
3 hours and 20 minutes = 3×60 +20
= 180+20=200
Here, one hour=60 minutes charges 120
1 minute charges = 120/60
= 2
200 minute charges = 2×200=400
Therefore If a lawyer charges 120 an hour then the bill for 3 hours and 20 minutes will be 400.

34 (f) The reference angle is 75°
40 (e) cos(θ) = -8/9
43 (e) sin(θ) = √3/2
What are trigonometric functions?The trigonometric functions provides the relationships between an angle and the three sides of a right triangle.
33 (e) The measure of the angle from the curve of the angle mark is found as follows;
The angle turned = 360 + (90 - θ)
Where; θ = π
Angle = 360° + (90 - π)° = (450 - π)°
34 (f) The reference angle is smallest (acute) angle made by the terminal side and the x-axis.
From the diagram, the reference angle is 360° - 285° = 75°
40 (e) The angle is in the Quadrant III
cos(θ) in Quadrant III is -cos(φ), where;
φ = θ - 180
From the diagram, cos(φ) = 8/√((-8)² + 17)
cos(θ) = -8/(√((-8)² + 17)) = -8/9
40 (f) The angle is in Quadrant II
sin(θ) = sin(φ), where; φ = 180 - θ
Therefore;
sin(φ) = 5/√((-3)² + 5²) = 5/√(34)

The probability that the distance between the two points is more than 1/3 is 0.
The length of the given line segment is 1, so the two points chosen independently at random cannot be more than 1 unit apart.
That is, the maximum distance between the two points is 1. However, the question states that we are looking for the probability that the distance between them is more than 1/3.
Since the maximum distance between the two points is 1, and 1/3 is less than 1, it is impossible for the distance between them to be more than 1/3. Therefore, the probability that the distance between the two points is more than 1/3 is 0.

based off of this information, what conclusions can be made about the mean value theorem? this contradicts the mean value theorem since f satisfies the hypotheses on the given interval but there does not exist any c on (1, 4) such that f '(c)
The correct option is; 4: this contradicts the Mean Value Theorem since there exists a c on (1, 7) such that f '(c) = f(7) − f(1) (7 − 1) , but f is not continuous at x = 3.
Explain the term Mean Value Theorem?The Mean Value Theorem says that there occurs a point c in the interval (a,b) so that f'(c) equals the function's average rate of change throughout [a,b] if a function f is continuous just on closed interval [a,b] as well as differentiable just on open interval (a,b).The function being used is;
f(x) = (x - 3)⁻²
If we separate this function according to x, we obtain;
f'(x) = -2/(x - 3)³
Finding all c values f(7) − f(1) = f '(c)(7 − 1).is our goal.
This suggests that;
0.06 - 0.25 = -2/(c - 3)³ x 6
-0.19 = -12/(c - 3)³
(c - 3)³ = 63.157
c = 6.98

In statistics, the probability that a population parameter will fall between a set of values a predefined percentage of the time is known as the confidence interval. Analysts typically use confidence intervals that cover 95% or 99% of the expected observations while assessing data. In frequentist statistics, an estimation range for an unknown parameter is referred to as a confidence interval. The most common confidence level for computing confidence intervals is 95%, however other levels, such 90% or 99%, are also occasionally employed. The conclusion is reached that the result is statistically significant if the confidence interval eliminates the value of zero effect.
If (μ₁- μ₂=0) is included in the confidence interval, that means this two means have the same difference that is zero.
Therefore, they may be nearly same,

Find the x and y intercepts
4x - 5y = 40
Answer:
x-intercept is (10,0)
y-intercept is (0, -8)
Step-by-step explanation:
Our equation is 4x - 5y = 40
Let's find x-intercepts first
X-intercepts is when the y = 0
So we put 0 in for the y, and we have the equation
4x =40
x =10
So our x-intercept located at (10,0)
Now find the y-intercepts
Y-intercepts is when the x = 10
So we put 0 in for the x, and we have the equation
-5y = 40
y= -8
So our y-intercept is located at (0,-8)
Answer:
Step-by-step explanation:
Y-int: (0, -8)
X-Int: (10, 0)
To find the y and x intercepts you have to plug in the 0 for the variable. You'd get 4(0)-5y=40 you get this by plugging in the 0 for x and then you solve. 4 x 0 is 0 so you'd get -5y=40 divide -5 on both sides and get y=-8 meaning that is the y-intercept.
You'd do the same when you look for the x-int. Just that you'd plug in a 0 for y instead of x. Which is 4x-5(0)=40. -5 x 0 is 0. So you'd have 4x=40 divide both sides by 4 and you'd get x=10 meaning that is the x intercept.
Remember that when looking for the y- intercept there should always be a zero in front meaning the x-value, and when looking for the x-intercept there should always be a zero in the back meaning the y-value.
(Hopefully you were able to understand how I got the x and y intercepts for this equation)

According to the information given in the question,
Quantity of the container of the disinfectants = 2 gallon
The price of a 2-gallon container of disinfectants = is $23.76
The concept used in this question is Ratio and Proportion,
The ratio is defined as the representation of two numbers in a fraction but in the case of ratio and proportion two numbers are separated by using a sign = ":"
Let us assume two numbers a and b,
If we have to present these two numbers in fractions = [tex]\frac{a}{b}[/tex].
If we have to present these two numbers in ratios = a : b.
According to the given question,
A 2-gallon container of disinfectants costs = $23.76
1 gallon = 4 quarts
So if 2 gallons = $23.762
= 2 gallons = 2 x 4
= 8 quarts
So, 8 quarts = $23.76
Now we will be dividing both sides by 8,
⇒ 1 quart = [tex]\frac{23.76}{8}[/tex]
⇒ 1 quart = $2.97
Therefore, the price per quart of disinfectant is = $2.97

Using logical reasoning, we know that Aha's current body temperature after taking the medicine is 34°C.
What is logical reasoning?Deductive reasoning, often known as logical reasoning, is the process of drawing conclusions from a body of facts or evidence.
It involves putting specific premises in front of conclusions.
Induction and abduction are two additional categories of logical reasoning that are typically distinguished in addition to the formal deduction.
If one has a premise or precondition, a conclusion or logical consequence, and a rule or material conditional that signals the conclusion given the premise, one can explain the following.
So, we know that:
The normal body temperature of the body is 37°C.
Aha current body temperature is 3 more than normal body temperature, then it is: 37 + 3 = 40°C (Current body temperature)
After taking medicine,
Temperature is 6° less than current body temperature, that is:
40 - 6 = 34°C
Temperature is 3° less than the normal body temperature, that is:
37 - 3 = 34°C
Then, the current temperature after taking medicine: 34°C
Therefore, using logical reasoning, we know that Aha's current body temperature after taking the medicine is 34°C.

The length of shorter leg is 15 inches, length of longer leg is 36 inches and the length of hypotenuse is 39 inches.
What is right triangle?
A right triangle, also known as a right-angled triangle, an orthogonal triangle, or formerly a rectangled triangle, is a triangle with one right angle, meaning that its two sides are perpendicular. Trigonometry's foundation is the relationship between the right triangle's sides and other angle.
Let,
x = Longer leg of triangle
y = Shorter leg of triangle
h = Hypotenuse of triangle
Given: The length of the longer leg of a right triangle is 6inches more than twice the length of the shorter leg.
The length of the hypotenuse is 9inches more than twice the length of the shorter leg.
⇒ x = 6 + 2y
h = 9 + 2y
The given triangle is a right angled triangle.
⇒ x^2 + y^2 = h^2
(6 + 2y)^2 + y^2 = (9 + 2y)^2
36 + 24y + 4y^2 + y^2 = 81 + 36y + 4y^2
36 + 24y + 5y^2 = 81 + 36y + 4y^2
36 - 81 + 24y - 36y + 5y^2 - 4y^2 = 0
-45 - 12y + y^2 = 0
y^2 - 12y - 45 = 0
y^2 - 15y + 3y - 45 = 0
y(y - 15) + 3(y - 15) = 0
(y - 15)(y + 3) = 0
y - 15 = 0, y + 3 = 0
y = 15, y = -3
Since the length is not negative.
So, y = 15
Hence,
Shorter leg = 15 inchs
Longer leg = 6 + 2y = 6 + 2(15) = 36 inches
Hypotenuse = 9 + 2y = 9 + 2(15) = 39 inches

Since the function increases; stops; and decreases x= -2 has to be a maximum. Similarly, x=0 is a minimum and x=2 is an inflection point. (They are "relative" max/mins as opposed to absolute.
"Critical Points" (maximums, minimum and inflection points) occur when the first derivative of the function is zero. Here f(x) is neither increasing nor decreasing at that exact point. When f '(x) is positive, f(x) is increasing; when f '(x)is negative f(x) is decreasing. In this case, the critical points are x= -2, 0, 2. For x<-2 the derivative is positive so the function is increasing, for x>-2 the derivative is negative so the function is decreasing.
b) When f '(x) is positive, f(x) is increasing; when f '(x) is negative f(x) is decreasing. In this case, the critical points are x= -2, 0, 2. For x<-2 the derivative is positive so the function is increasing, for x>-2 the derivative is negative so the function is decreasing.
Concavity is determined by the second derivative, which is easy to sketch from the first. Where f '(x) is decreasing, f ''(x)is negative; where f '(x) is increasing f ''(x) is positive.

In this case, the function f(x)=2x²+3 represents the rate of a boat traveling with the current in miles per hour and the function g(x)=x+ 2 represents the time the boat traveled in hours. This will be illustrated as:
f(x) = 2x² + 3.
g(x) = x + 2
Therefore, we will evaluate the product
(f . g)(x) = (2x² + 3(x + 2)
(f . g)(x) = (2 × 2² + 3)(2 + 2)
(f . g)(2) = 44

The difference between the meaure of two comlementary angle i 14. Find the meaure of both angle
The measure of the first angle is 70° and the measure of the second angle is 100°.
The measure of complementary angles is the sum of their angles equal to 180°. Thus, if one angle has a measure of 70°, then the other angle must have a measure of 180° - 70° = 110°. Since the difference between the two angles is 14°, the first angle must have a measure of 70°, and the second angle must have a measure of 100°. This is because if the first angle has a measure of 70°, then the second angle must have a measure of 110°. Since the difference between the two angles is 14°, the second angle must have a measure of 100° in order to meet this difference. Therefore, the measure of the first angle is 70° and the measure of the second angle is 100°.
