5 yrs ago, Nuri was thrice as old as Sonu. 10 yrs later, Nuri will be twice as old Sonu. How old are Nuri n Sonu?
Answer:
Answer will be 50
Step-by-step explanation:
Let us suppose, present age of Nuri be ‘x’ years and present age of Sonu be ‘y’ years.
Now, it is given that five years ago, Nuri was thrice old as Sonu. Hence,
Five years ago,
Nuri’s age = x-5 years
Sonu’s age = y-5 years
And relation between ages can be given as
Nuri’s age = 3×sonu’s age or
x-5 = 3(y-5)
x-5 = 3y-15
x-3y+10 = 0 ………..(i)
Another relation is given in the problem that ten years later, Nuri is twice as old as Sonu.
So, ten years ago,
Nuri’s Age = x+10
Sonu’s Age = y+10
And relation between ages can be written as
x+10 = 2(y+10)
x+10 = 2y+20
x-2y-10 = 0 …………..(ii)
Now we can solve the equation (i) and (ii) to get values of x and ‘y’ or present ages of Nuri and Sonu.
Value of ‘x’ from equation (i) be
x = 3y-10 ……….(iii)
Putting value of ‘x’ from equation (iii) in equation (ii) we get,
3y-10-2y-10 = 0
y = 20
Now, from equation (iii) value of ’x’ can be given as,
x= 3(20)-10
x = 50
Hence, the present ages of Nuri and Sonu are 50 years and 20 years respectively.

What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 2 chaperones are needed for every 25 students. How many are needed for 100 students? The rule of three is given by:
2 chaperones - 25 students
n chaperones - 100 students
Applying cross multiplication:
25n = 2 x 100
n = 200/25
n = 8.

A(n) ___ function is the function that sometimes results when the independent variable of a function is exchanged with the dependent variable.
The A(n) is inverse function is the function that sometimes results when the independent variable of a function is exchanged with the dependent variable.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We know that the inverse of a function, sometimes known as an anti function, is a function that can be reversed into another.
In other words, if a function "f" converts x to y, the inverse of the same function will convert y to x. The inverse function is denoted by f⁻¹ or F⁻¹ if the function is denoted by 'f' or 'F'.
Thus, the A(n) is inverse function is the function that sometimes results when the independent variable of a function is exchanged with the dependent variable.

A survey indicated that 4 out of 6 doctors used brand X aspirin. If 3600 doctors were surveyed, how many used brand X?
Answer: 2,400 doctors used brand X aspirin.
Step-by-step explanation: The question notifies us that 3,600 total doctors were surveyed. This automatically lets us know that 6/6 doctors = 3,600 doctors. We can find the unit rate from this point by dividing 3,600 by 6. We will find that 600 doctors represents 1/6 doctors. We can multiply our unit rate by 4 to find that 4 out of 6 doctors, or 2,400 doctors, use brand X aspirin. 4/6 of 3,600 is 2,400, so 2,400 doctors used brand X aspirin. Hope this helps!
Answer:
1200 doctors
Step-by-step explanation:
60% of doctors use brand X aspirin.
So, what is 60% of 2000?
(0.6) (2000) = 1200
1200 out of the 2000 use brand X.

G.MG.3 Beth is going to enclose a rectangular area in back of her house. The house wall will form one of the four sides of the fenced in area, so Beth will only need to construct three sides of fencing. Beth has 48 feet of fencing. She wants to enclose the maximum possible area.
The maximum area of the rectangular path is when the length is 24 feet and the width is 12 feet.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the length and y represent the width. Hence:
There is 48 feet of fencing:
x + 2y = 48
x = 48 - 2y (1)
The area (A) is:
A = xy = y(48 - 2y)
A = 48y - 2y²
The maximum area is at A' = 0, hence:
48 - 4y = 0
y = 12
x = 48 - 2(12) = 24
The maximum area of the rectangular path is when the length is 24 feet and the width is 12 feet.

Determine whether the successive probabilities are independent or dependent events.
15) The probability of getting 4 tails in a row when flipping a coin?
a) Independent
b) Dependent
16) The probability of drawing 2 Queens in a row from a deck of cards?
a) Independent
b) Dependent
Answer:
15) a) independent 16) b) Dependent Step-by-step explanation:
15) let T1 be the event : “get a tail in the first flip”
let T2 be the event : “get a tail in the second flip”
p(T1 ∩ T2) = 1/4
p(T1) = 1/2
p(T2) = 1/2
Then
p(T1) × p(T2) = (1/2)(1/2 = 1/4
Since ,p(T1 ∩ T2) = 1/4 = p(T1) × p(T2)
Then the events are independent.
16) These events are dependent since we don’t replace the Queen before the second draw.
The two Events are dependent because the probability that we draw a Queen in the first draw affect the probability that we draw a Queen in the second draw.

At a cake stall , muffins cost $2 each & cookies cost $1 each. The cake stall earned $146. If 2 more cookies than muffins were sold, how many muffins were sold?
Answer:
48 muffins were sold
Step-by-step explanation:
Represent the number of muffins by m and the number of cookies by c.
Then the revenue from the sales of muffins was ($2/muffin)m and that from the sales of cookies ($1/cookie)c. Remembering that c = m + 2, we obtain the following equation:
($2/muffin)m + ($1/cookie)(m + 2) = $146, so that:
2m + 1m + 2 = 146, or 3m + 2 = 146, or 3m = 144.
Dividing both sides of this result by 3, we get m = 48
Thus, 48 muffins were sold.

a bicycle wheel has a diameter of 65cm what is the length of one revolution of the wheel PLEASE HELP
AnswerAnswerAnswerAnswer: C = πd = 65π = 204.2 cm
Step-by-step explanation: C = pi*d
where d is the diameter.
First we get the circumference, then we multiply it by the number of revolutions, which is 20:
C = 3.14 * 65
C = 204.1 cm (this is only equal to 1 revolution)
Therefore, total distance travelled in after 20 revolutions is
204.1 * 20 = 4082 cm
