Given :-Meena mother is 4 times as old as Meena After 5 years, Her mother will be 3 times as old as she will be then. To Find :-We have to find the present ages of Meena and her mother. Let's Begin :-Let the present age of Meena be ' x ' years.
Now, It is given in the question that her mother is 4 times as old as MeenaThat means,
Present age of her mother
[tex]\sf{ = 4x \: years }[/tex]
Now,
After 5 years
The age of the Meena will be
[tex]\sf{ = x + 5 \: years }[/tex]
Therefore,
According to given condition,
The age of her mother will be
= [tex]\sf{ = 4x + 5 \: years ...eq(1)}[/tex]
But, It is given that,
After 5 years, Her mother will be 3 times as old as Meena.That is,
After 5 years, Her mother age will be
[tex]\sf{ = 3(x + 5) \: years ...eq(2)}[/tex]
From eq(1) and (2) :-
[tex]\sf{ 4x + 5 = 3(x + 5) }[/tex]
[tex]\sf{ 4x + 5 = 3x + 15}[/tex]
[tex]\sf{ 4x - 3x = 15 - 5 }[/tex]
[tex]\sf{ x = 10 \: years }[/tex]
Thus, The present age of the Meena will be 10 years.
Therefore,
The present age of her mother will be
[tex]\sf{ 4x = 4 × 10 }[/tex]
[tex]\sf{ = 40 \: years }[/tex]
Hence, The present of Meena and her mother is 10 years and 40 years.

Mr frank bought 6 pounds of grapes and 3 pounds of apples in the store. he paid $28.20 for the whole purchase. his neighbor mrs. bland pain $16.90 for 2 pounds of grapes and 4 pounds of apples. if all of the apples in the store cost the same and all grapes cost the same, what is the price of one pound of grapes?
The price of one pound of grapes and one pounds of apples in the store is $3.45 and $2.5 respectively.
Simultaneous equationlet
x = price of grapesy = price of apples6x + 3y = 28.20
2x + 4y = 16.90
multiply equation (2) by 36x + 3y = 28.20
6x + 12y = 50.70
subtract the equation9y = 22.50
y = 22.50/9
y = $2.5
substitute y into (2) in
2x + 4y = 16.90
2x + 4(2.5) = 16.90
2x + 10 = 16.90
2x = 16.90 - 10
2x = 6.90
x = 6.90/2
x = $3.45

One year, the population of a city was 73,000. Several years later it was 85,410. Find the percentage decrease
The percentage decrease is 14.52% if, one year, the population of a city was 73,000. Several years later, it was 85,410.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
The initial population = 85410
The final population = 73000
The decrease = (85410 - 73000)/85410 = 0.1452
The percentage decrease = 0.1452×100 = 14.52%
Thus, the percentage decrease is 14.52% if one year, the population of a city was 73,000. Several years later, it was 85,410.

Leanne and her family plan to attend a symphony at an orchestra hall. Before booking the tickets, Leanne checked a website where visitors rated the view of the symphony's soloist from their seating section. The data from the website is summarized in the table.
Section Number of reviewers who sat in the section Number of reviewers who rated the view as "perfect"
L1 90 57
L2 52 33
L3 75 47
U1 84 55
U2 43 27
U3 35 22
According to the data from the website, in which seating section should Leanne's family book the tickets if they want to maximize their chances of having a "perfect" view of the symphony's soloist?
Using proportions, it is found that Leanne's family should book their tickets at Section U1 to maximize their chances of having a "perfect" view.
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, the section with the highest proportion of perfect views should be chosen, hence:
pL1 = 57/90 = 0.633
pL2 = 33/52 = 0.635
pL3 = 47/75 = 0.623
PU1 = 55/84 = 0.655
pU2 = 27/43 = 0.628
pU3 = 22/35 = 0.629
Leanne's family should book their tickets at Section U1 to maximize their chances of having a "perfect" view.

Step-by-step explanation:
A flagpole casts a shadow that is 50 feet long. At the same time, a woman standing nearby who is 6 feet tall casts a shadow that is 3 ft long. How tall is the flagpole?
The height of the flagpole is 100 feet.
What are shadows?Shadows are area devoid of light as a result of the obstruction of light by an opaque object.
Analysis:
The length of the shadow and the height of the flagpole are at right angles.
Similarly, the height of the woman and the length of her shadow are at right angles. Making both similar right-angled triangles.
The ratio of the height of the woman to that of pole is equal to ratio of the length of woman's shadow to that of the flagpole.
let length of flagpole be h.
height of woman = 6 feet
length of shadow of woman = 3 feet
length of shadow of pole = 50 feet.
[tex]\frac{6}{h}[/tex] = [tex]\frac{3}{50}[/tex]
3h = 300
h = 100 feet
In conclusion, the height of the flag pole is 100 feet.
