A city has a population of 330,000 people. suppose that each year the population grows by 3.25. what will the population be after 8 yesrs
The population of the city after eight years is 35,125,731,743
What is population growth rate?Population growth is the increase in the number of people in a population or dispersed group. The expression P(t) = P(o)(1+r)^t can be used to determine the growth rate of a population.
Where P(t) is the population at a particular time
P(o) is the initial population , t is the time and r is the growth rate.
Here the growth rate has been given, but we are to find p(t).
P(t) = 330,000(1+3.25)⁸
P(t) = 330,000(4.25)⁸
P(t) = 330,000× 106441.61
P(t) = 35,125,731,743( nearest billion)
Therefore the population of the city after 8years is 35,125,731,743

Find the values of x and y in parallelogram PQRS. PT=y, TR=5x+1, QT=2y, TS=6x+10 x= ? and y= ?
The required values of x and y are x = 2 and y = 11.
We have been given that parallelogram PQRS which has:
PT = y, TR = 5x+1, QT = 2y, TS = 6x+10
We know that the diagonals of a parallelogram bisect each other.
So, PT = TR and QT = TS
Substitute the values and we have a system of equations:
y = 5x + 1 ....(i)
2y = 6x + 10 ....(ii)
Substitute the value of the equation y = 5x + 1 in equation (ii), and solve for x
2(5x + 1) = 6x + 10
10x + 2 = 6x + 10
10x - 6x = 10 - 2
4x = 8
x = 8/4
x = 2
Substitute the value of x = 2 in equation (i), and solve for y
y = 5(2) + 1
y = 10 + 1
y = 11
Therefore, the required values of x and y are x = 2 and y = 11.

your shift runs 8 hours. from the 8 hours, 30 minutes is allowed for lunch and 30 minutes for breaks. you must produce 78.0 units per shift. give the takt time in minutes.
The stated statement indicates that the takt time is 5.38 minutes for each section.
What is an example of takt time?Takt time is calculated as the amount of manufacturing time that is available divided by the volume of orders. Takt time, for instance, is two minutes if a factory makes widgets for 480 minutes a day and clients need 240 widgets per day. Similar to this, the takt time is one week if clients desire two new goods per month.
How does takt time change?Takt time depends on client demand and the amount of time that is available, and for many items, it is always changing as the demand from the market shifts. Takt time is unaffected by system changes, although cycle time is affected.
Briefing:Available hours are 7 * 60 minutes, which is 420 minutes.

After solving the equation, we can conclude that Callie should rent the bicycle for a maximum of 3 hours.
What are equations?The equals sign is indeed a symbol used in mathematical formulas to denote the equality of two reactions.
Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
For example, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.
So, according to the given information, form the equation as follows:
12x + 10 = 45
Where x is the number of hours Callie rents the cycle.
Now, calculate for x as follows:
12x + 10 = 45
12x = 45 - 10
12x = 35
x = 35/12
x = 2.91

What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
Two triangles in a composite triangle.
We see that,
m∠UST = m∠STR
This means,
x + 4 = 13
x = 13 - 4
x = 9
The sum of the angles in a triangle is 180 degrees.
One triangle is an equilateral triangle.
All three angles are equal.
This means,
The angle has to be 60°.
m∠UTR + m∠URT + m∠TUR = 180
3m = 180
m = 60
Now,
m∠URS = 180
m∠URT + m∠SRT = 180
60 + m∠SRT = 180
m∠SRT = 120
The isosceles triangle has two equal angles.
m∠RTS = m∠RST
m∠SRT + m∠RTS + m∠RST = 180
120 + 6y + 6y = 180
12y = 180 - 120
12y = 60

A survey of 70 people found that 50 people like coffee, 25 like tea, and 13 like both.How many people like coffee or tea, or both?
Step-by-step explanation:
your question is strange.
first you tell us that 50 people like coffee, 25 like tea, and 13 like both.
and then you ask how many like coffee or tea or both.
is this a joke ? or do you rather mean how many like only coffee, or only tea, and how many don't like neither ?
since 13 people like coffee and tea, these 13 are also part of the group of 50 that like coffee, and of the group of 25 that like tea.
so, to get the number of people that like only one, we need to deduct the number of people, who like both from both groups.
the number of people that only like coffee is therefore
50 - 13 = 37
and the number of people that only like tea is
25 - 13 = 12
we know the number of people that like coffee and tea is 13.
together that are
37 + 12 + 13 = 62 people.
that means 70 - 62 = 8 people don't like neither coffee nor tea.
Answer: 62
Step-by-step explanation:
Those who like coffee only = 50 - 13 = 37. Those who like tea only = 25 - 13 = 12. Those who like either coffee, or tea, or both = 37 + 12 + 13 = 62.
In theory, the 70 people being surveyed could fall under any of the following four categories:
Those who like coffee,Those who like tea,Those who like both coffee and tea,Those who like neither coffee nor tea.I have labelled the four categories 1, 2, 3 and 4 for convenient reference.
From the information provided in the question, category 1 contains 50 people, category 2 contains 25 people, while category 3 contains 13 people. We do not yet know how many people fall under category 4, but we shall calculate it.
We know from set theory that the four aforementioned categories are known formally as sets. A set is simply a group of objects or things that are similar in some way. Each of the objects in a set is called a member of that set. Two sets can intersect. The intersection of two sets is simply the collection of members that are in both of the two sets. Also, two sets can unite. The union of two sets is the collection of members that in either of the two sets.
For example, category 3 is the intersection of category 1 and 2. The question requires us to calculate the union of category 1 and 2.

Find the slope of the line that contains the following points: (17, -12)(17,−12) and (17,(17, 8)
Answer:
Slope is undefined. { Infinity }
Step-by-step explanation:
Formula we use,
→ Slope(m) = (y2 - y1)/(x2 - x1)
Now required slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (8 + 12)/(17 - 17)
→ m = 20/0
→ [ m = 0 ]
Hence, the slope is undefined.
The slope of the line passing through the points ( 17 , -12 ) and ( 17 , 8 ) is undefined
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 17 , -12 )
Let the second point be Q ( 17 , 8 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 8 - ( -12 ) ) / ( 17 - 17 )
On simplifying the equation , we get
Slope m = ( 8 + 12 ) / 0
Slope m = 20 / 0
So , the slope is undefined

Mike charged for each shirt is $2.49, each pair of slacks is $5.99 and each sports coat is $7.99.
What is system of equations?
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system.
Let
Price of shirts = x
Price of slacks = y
Price of sports = z
From the given information,
3x + y = $13.46 ..(1)
7x + 3y + z = $43.39 ..(2)
5x + 2z = $28.43 ..(3)
From equation (1), y = 13.46 - 3x
From equation (3), z = (28.43 - 5x) / 2
Plug the value of x and z in equation (2)
7x + 3(13.46 - 3x) +(28.43 - 5x)/2 = 43.39
7x + 40.38 - 9x + 14.22 - 2.5x = 43.39
-4.5x +54.6 = 43.39
4.5x = 54.6 - 43.39
4.5x = 11.21
x = 2.49
Plug x = 2.49 in equation (1)
3(2.49) + y = 13.46
2.47 + y = 13.46
y = 5.99
Plug x = 2.49 in equation (3),
5(2.49) + 2z = 28.43
12.45 + 2z = 28.43
2z = 15.98
z = 7.99

The factored form of the polynomial x + 9x + 20 is (x + 4)(x + 5). To obtain this form, we can use the factoring method known as "FOIL," which stands for "First, Outer, Inner, Last." This method involves multiplying the first terms, the outer terms, the inner terms, and the last terms of the two factors to obtain the original polynomial.
In this case, if we let the factors be (x + 4) and (x + 5), we can use FOIL to multiply them and obtain the following:
(x + 4)(x + 5) = (x * x) + (4 * x) + (x * 5) + (4 * 5)
This simplifies to:
(x + 4)(x + 5) = x^2 + 9x + 20
As we can see, the result is the original polynomial. Therefore, the factored form of x + 9x + 20 is (x + 4)(x + 5)
The value of the factored form of the polynomial are,
