what is ratio?Ratios show how often one number is contained in another in mathematics. For instance, the ratio of oranges to lemons in a fruit dish is 8 to 6 if there are 8 oranges and 6 lemons present. In a similar vein, the proportion of oranges to whole fruit is 8, while that of lemons to oranges is 6:8. A ratio is an ordered pair of numbers a and b that is expressed as a / b, with b not equal to zero. An equation equating two ratios is known as a ratio. The ratio can be expressed as 1:3, for instance, if there is 1 boy and 3 girls (for every boy she has 3 girls) 3/4 are girls, while 1/4 are boys.
ratio is = 2:5:7
2x + 5x + 7x = 84

44000
4800
8400
The size of the crowd that is 5 feet deep on both sides of the street along a 3-mile section of a parade route is 44000 people.
What is area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Given that, the size of a crowd that is 5 feet deep on both sides of the street along a 3-mile section of a parade route,
The number of people that can fit comfortably in a 6 feet by 6 feet area = 10
The ratio of the number of people per unit area = 10/(6 × 6) = 10/36
The area, A, occupied by the crowd = 5 feet × 3 mile × 2
3 miles = 15840 feet
∴ A = 5 feet × 15840 feet × 2 = 158400 ft²
We then have;
Number of people / 158400 = 10/36
Number of people = 44000
Hence, the size of the crowd that is 5 feet deep on both sides of the street along a 3-mile section of a parade route is 44000 people.

How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We need to Write the percent as a fraction in simplest form
16.24%
So, we can rewrite it as;
16.24 / 100
16 and 24/100 or 16 6/25
So the percent as a fraction is 16 6/25
Given;
An antique vase costs $2000
Its price increases by 4.5%
Now,
Let the 4.5% of price be x

A EF = 22
B EF = 11
C EF = 16
D EF = 20
Answer:
A
Step-by-step explanation:
the midsegment EF of the trapezoid ABCD is half the sum of the parallel bases, that is
EF = [tex]\frac{AB+DC}{2}[/tex] ( substitute values )
x + 6 = [tex]\frac{2x-9+x+5}{2}[/tex]
x + 6 = [tex]\frac{3x-4}{2}[/tex] ( multiply both sides by 2 to clear the fraction )
2x + 12 = 3x - 4 ( subtract 3x from both sides )
- x + 12 = - 4 ( subtract 12 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
Then
EF = x + 6 = 16 + 6 = 22

Explain Maxima and Minima in mathematics?Maxima and Minima are known as the extrema of a function. Maxima and minima are the maximum or the minimum value of a function within the given set of ranges. For the function, under the entire range, the maximum value of the function is known as the absolute maxima and the minimum value is known as the absolute minima.Local Maxima : A point x = b is a point of local maximum for f(x) if in the neighborhood of b i.e in (b−, b+) where can be made arbitrarily small, f(x) < f(b) for all x ∈ (b−, b+)∖{b}. This simply means that if we consider a small region (interval) around x = b, f(b) should be the maximum in that interval.Local Minima : A point x = a is a point of local minimum for f(x) if in the neighbourhood of a, i.e. in (a−,a+), (where can have arbitrarily small values), f(x) > f(a) for all x ∈ (a−,a+)∖{a}. This means that if we consider a small interval around x = a, f(a) should be the minimum in that interval.Given is that when an object is thrown upward with an initial velocity of v{0}, then its approximate height is given by this quadratic function -
S = - 4.9t² + [tex]$v_{o} ^{t}[/tex] + h
The approximate height is given by this quadratic function -
S = - 4.9t² + [tex]$v_{o} ^{t}[/tex] + h
{ 1 } - For the maximum height :
dS/dt = 0 ... Eq{ 1 }
dS/dt = -9.8t + [tex]$3.1^{t}[/tex] log(3.1) + 0 = 0
- 9.8t + [tex]$3.1^{t}[/tex] log(3.1) = 0
Refer to the graph attached. At t = 3.8 {possible value}, the function is 0.
So we get -
t = 3.8 s ... Eq{ 2 }
Maximum height achieved -
h{max} = - 9.8t + [tex]$3.1^{t}[/tex] log(3.1) + 15
h{max} = - 9.8 x 3.8 + [tex]$3.1^{3.8}[/tex] log(3.1) + 15

Han should expect to pay $90 for the ticket if he buys it the day of the game.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Han should expect to pay $90 for the ticket if he buys it the day of the game
The current ticket fee = $30
The markup = 200%
The markup = 200% of the current price
Markup = 200/100 ×30

For the linear equation y = -3.5x + 50 the graph is plotted with points (0,50) and (14.28,0).
What is a linear equation?
A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.
The linear equation is y = -3.5x + 50.
An arcade deducts 3.5 points from a 50-point game card for each game played.
The graph will represent the x axis as number of games played.
The graph will represent the y axis as points earned.
Substitute the value x = 0 in the equation -
y = -3.5(0) + 50
y = 50
The coordinate point is (0,50).
Substitute the value y = 0 in the equation -
0 = -3.5x + 50
-50 = -3.5x
x = 14.28
The coordinate point is (14.28,0).
Plot both the coordinate points and join the line.
