By considering ages and equations we have,
Uncle Rob will be 62 years old when Dave is 32.
Dave is listed as being 15 years old, while his uncle Rob is listed as being three times Dave's age. Rob's age as of right now may be calculated using the formula below:
Age of Rob is Dave times three.
Using Dave's age as a plug-in, we obtain following equations,
Rob's age is equal to 15 + 3 = 45.
Rob is currently 45 years old, according to this.
We need to know how many years it will be before Dave turns 32 in order to calculate Rob's age at that time. By deducting Dave's present age from his anticipated age, we may determine this:
Years from now = Dave's age in the future minus Dave's age currently
By entering the specified values, we obtain:
The number of years from now is equal to 32 - 15 = 17 years.
Dave will turn 32 in 17 years, according to this.
We may multiply Rob's current age by the number of years from now to determine his age at that point:
When Dave reaches the age of 32, Rob will be that age plus the number of years.
When we enter the calculated values, we obtain:
When Dave is 32 years old, Rob will be 45 + 17 years old, or 62 years old.
So, Dave uncle rob 's age will be 62 years old.
As a result, when Dave's age is 32, his uncle Rob's age will be 62.

Determine whether each function has a constant or variable rate of change. Use rates of change to determine whether each function is linear or nonlinear. answer
We can also check if the function's equation is in the form y = mx + b.
What is function's equation ?
A function's equation is a mathematical statement that defines the relation between the input (also known as independent variable) and output (also known as dependent variable) of a function. The equation is typically represented by the letter "y" for the output, and one or more letters for the input (usually "x").
To determine whether a function has a constant or variable rate of change, we need to find the slope or rate of change between two points on the function. If the slope remains the same no matter what two points we choose, the function has a constant rate of change and is linear. If the slope changes depending on the two points we choose, the function has a variable rate of change and is nonlinear.
To determine whether a function is linear or nonlinear, we can also check if the function's equation is in the form y = mx + b, where m and b are constants. If it is, the function is linear, otherwise it is nonlinear.
It's important to mention that, in order to have a definitive answer, we need the function to be defined.

The length of the side of the smaller square is 7 inches.
Let x be the length of the side of the smaller square.
The length of each side of a square is 3 inches more than the length of each side of a smaller square. Thus the length of the side of the larger square is
(x + 3) inches.
The area of the smaller square is
x^2 square inches.
The area of the larger square is
(x + 3)^2 square inches.
We can set up the equation:
x^2 + (x + 3)^2 = 149
Expanding and simplifying the equation gives:
x^2 + x^2 + 6x + 9 = 149
Combining like terms:
2x^2 + 6x - 140 = 0
Using the quadratic formula, we can solve for x:
x = (-b ± √(b^2 - 4ac)) / 2a
x = (-6 ± √(6^2 - 4 * 2 * (-140))) / 2 * 2
x = (-6 ± √(36 + 1120)) / 4

Otis wants to borrow 10000 to buy a used car. he examined his budget and decided that he can afford a payment of $200 a month. if his bank offers him a rate of 7.5%, how long should he borrow the money so he can afford his monthly payment?
Answer: Otis should borrow the money for 60 months (5 years) so he can afford his monthly payment of $200.
Step-by-step explanation: To calculate the duration of the loan, we can use the formula:
Duration (in months) = Loan amount / Monthly payment
In this case, the loan amount is $10,000, and the monthly payment is $200. So by substituting the values, we get:
Duration (in months) = 10000 / 200 = 50
The duration of the loan is 50 months, however, the bank offers him a rate of 7.5%.
To calculate the total interest, we can use the formula:
Total Interest = Loan amount * Interest Rate * Duration (in months) / 12
The total interest is = 100007.5/10050/12 = 3750
So the Otis will have to pay an additional $3750 in interest over the course of the loan.
So, the total amount he will have to pay is 10000+3750 = 13750
And the time duration to pay this amount is 60 months ( 5 years)
Note: As per the information provided, the interest rate is not annual, it is monthly. So, it is not necessary to divide it by 12 in the interest formula. The equation should be Total Interest = Loan amount * Interest Rate * Duration (in months)

Russia 1996/4) In the Duma there are 1600 delegates, who have formed 16000 committees of 80 persons each. Prove that one can find two committees having at least four common members.
Answer:
Step-by-step explanation:
This problem can be solved using a technique called the Pigeonhole Principle. The Pigeonhole Principle states that if n+1 or more objects are placed into n pigeonholes, then at least one pigeonhole will contain two or more objects.
In this problem, we have 1600 delegates divided into 16000 committees of 80 persons each. We can think of each delegate as an object and each committee as a pigeonhole. Since 1600 delegates are placed into 16000 pigeonholes, we know that by the Pigeonhole Principle, at least one pigeonhole will contain two or more delegates.
In other words, there must be at least one committee that has at least two delegates in common with another committee. We can prove that there will be at least four common members by assuming the worse scenario where each committee is formed by different people, and noting that there are more delegates than the number of committees, so it's impossible that all committees have different members, and therefore there will be at least four common members.
Therefore, it is possible to find two committees having at least four common members.

A group of researchers investigated the effect of media usage (whether or not subjects watch television or use the Internet) in the bedroom on ""Tiredness"" during the day (measured on a 50 point scale a. Identify each of the variables, state whether the variables are quantitative or categorical, and identify each variable as either explanatory or response variables. nterviewed b. To collect these data, the researchers randomly selected homes to visit and i the adult member of the household whose birthday was nearest. Is this an experiment or an observational study? Briefly explain.
a. Media usage is categorical and Tiredness is quantitative. The effect of media is the explanatory variable and Tiredness is the response variable.
b. Yes, this is an observational study.
What is an Observational Study?In fields including epidemiology, social sciences, psychology, and statistics, observational studies draw conclusions from a sample of the population when the independent variable is not under the researcher's control due to ethical issues or practical constraints.In a normal observational study, participants are assigned to either the treated group or the control group, and the researcher observes how the therapy may influence them.This does not occur in experiments such as randomized controlled trials when each subject is randomly assigned to either a treated group or a control group. Observational studies by their very nature provide difficulties for inferential analysis due to the absence of an assignment process.This research was done via observation. The researchers are not modifying or controlling any variables; instead, they are watching and assessing the correlation between media use and fatigue. By visiting randomly chosen households and interviewing the adult household member with the closest birthday, they are gathering data.

Step-by-step explanation:
the size of a television screen is given by the length of diagonal of the screen. What size is a tv screen the is 21.6 inches wide and 16.2 inches high
The size of a television screen that is 21.6 inches wide and 16.2 inches high is approximately 27 inches (measured diagonally).
What is the Pythagorean theorem?
It's a relation in Euclidean geometry among the three sides of a right triangle. In it, the square of the hypotenuse is equal to the sum of the squares of the other 2 sides.
The size of a television screen can be found by using the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.
In this case, the length of the diagonal of the screen is the hypotenuse, the width is 21.6 inches, and the height is 16.2 inches. We can use the theorem to find the length of the diagonal:
diagonal²= width² + height²
diagonal² = 21.6² + 16.2²
diagonal² = 467.76 + 262.44
diagonal² = 730.2
diagonal = √730.2
diagonal ≈ 27 inches
Hence, the size of a television screen that is 21.6 inches wide and 16.2 inches high is approximately 27 inches (measured diagonally).

you were in the garden, there are 34 people in the yard. 30 people left. 35 people are in the garden. This can be solved using addition.
What is addition?Mathematically, addition is the process of merging several numbers together. The numbers that are being added are known as addends, and the outcome of the addition process, or the answer we ultimately obtain, is known as the sum. It is a fundamental mathematical operation that we employ on a daily basis. We add numbers in many different contexts. In arithmetic sums, the plus sign (+) is used to indicate addition.
The combination of at least two integers constitutes basic addition. Once a student has mastered counting, they may begin to study basic addition. By locating the addend at the top of the chart and tracing down to the row of the second addend, they may utilize an addition chart as a learning tool.
Given that,
there are 34 people in the yard.
Among them 30 people left.
Thus, (30 dead + 4 living + you ) = 35 people are in the garden.
