The smallest number of people when one could have been at the party is 211 people.
How to illustrate the information?This is a least common multiple question, also known as an LCM. We know this because all groups would have formed evenly if the one extra person had not arrived at the party. This means that there are 1 more people at the party than a number 2, 3, 5, or 7.
In this case, the number will be:
= (2 × 3 × 5 × 7) + 1
= 210 + 1
= 211
Applicable multiples of 7
(7 × 10) = 70 → 70 + 1 = 71 → 71/3 = 23 R2 → not possible
(7 × 20) = 140 → 140 + 1 = 141 → 141/3 = 47 → not possible
(7 × 30) = 210 → 210 +1 = 211 → 211/3 = 70 R1 → possible.
Therefore, the number of people is 211.

There are two more quarters than dimes and as many nickles as quarters and dimes together. The total amount of money is 3.75. How many quarters, dimes and nickles are there?
Answer: 9 quarters, 7 dimes, & 16 nickels
Step-by-step explanation:
We set number of dimes as d:
Number of quarters: d + 2Number of nickels: d + 2 + d = 2d + 2So, set up the equation to solve:
[tex]0.10d+0.25(d+2)+0.05(2d+2)=3.75\\\\0.10d+0.25d+0.5+0.1d+0.1=3.75\\\\0.45d=3.75-0.5-0.1=3.15\\\\d=7[/tex]
So now that we know there're seven dimes, we can plug them in our initial equations to find the number of quarters and nickels:
Number of quarters: d + 2 = 7 + 2 = 9Number of nickels: d + 2 + d = 2d + 2 = 2(7) + 2 = 16A & B = (A + B) x A + (A - B) divided by B. find the value of 4 & - 2.

inside a square with side length $10$, two congruent equilateral triangles are drawn such that they share one side and each has one vertex on a vertex of the square. what is the side length of the largest square that can be inscribed in the space inside the square and outside of the triangles?
Using the concepts of equilateral triangle, we got that 2.113 is the side length of the largest square that can be inscribed in the space inside the square and outside of the triangles.
Firstly we find the side length of equilateral triangle , G is the midpoint of side FE.
Let GE=x, since G is the midpoint due to that DE=GB.
So, using basic trigonometry=DG^GB=x√3.
Thus DB=2x√3.
Since DB is the diagonal of ABCD, it has length 10√2 Then we can set up the equation 2x√3=10√2. So the side length of the triangle is
2x=(10√2)/√3.
Now look at the diagonal AC it is made up of twice the diagonal of the small square plus the side length of the triangle. Let the side length of the small square be y:
Let the side length of the small square be y:
AC=y√2 + [(10√2)/√3]+y√2=10√2.
Solving for y:
=>y√2+y√2 + (10√2√3)/3=10√2
=>y√2+y√2 + (10√6)/3=10√2
=> [3y√2+3y√2 + (10√6)] /3=10√2
=>6y√2+10√6=30√2
=>6y√2 = 30√2-10√6
=>y√2 = (30√2-10√6)/6
=>y = (30√2-10√6)/6√2
=>y = (60-20√3)/12
=>y= 5(3−√3)3 or 2.113
Hence, inside a square with side length 10, two congruent equilateral triangles are drawn such that they share one side and each has one vertex on a vertex of the square. the side length of the largest square that can be inscribed in the space inside the square and outside of the triangles is to be 2.113.

A group of friends wants to go to the amusement park. They have $89.50 to spend on parking and admission. Parking is $7.75, and tickets cost $27.25 per person, including tax. Write and solve an equation which can be used to determine p, the number of people who can go to the amusement park.
I had trusted a VERIFIED answer and got it wrong, so for everyone in the future, here is the correct answer.
Answers:
Equation: 27.25p + 7.75 = 89.5
Answer: p = 3
The equation which can be used to determine p is 7.75 + 27.25p = 89.50, then the number of people who can go to the amusement park is 3
The total amount that they have to spend on parking and admission = $89.50
The parking cost = $7.75
The ticket cost including tax = $27.25
Consider the number of people who can go to amusement park as p
Then the equation will be
7.75 + 27.25p = 89.50
Subtract both side of the equation by 7.75
27.25p + 7.75 - 7.75 = 89.50 - 7.75
27.25p = 81.75
Divide both side of the equation by 27.25
27.25p / 27.25 = 81.75 / 27.25
p = 3
Hence, the equation which can be used to determine p is 7.75 + 27.25p = 89.50, then the number of people who can go to the amusement park is 3

Lourdes is reading a biography for her history class. She reads 30 pages each day. After 9 days, Lourdes has read (3)/(5) of the biography. Write a linear equation to represent the number of pages Lourdes still has to read after x days.
The linear equation is z = 450 - 30 x, where z is the number of pages Lourdes has left to read after x days
We need to write a linear equation to represent the number of pages
Lourdes has left the number of pages to read after x days
Lourdes reads 30 pages each day
Lourdes will read for x days
The number of pages Lourdes will read in x day = 30 x
The left pages will be the difference between the total pages of the
book and the pages Lourdes read.
After 9 days Lourdes completes 3/5 of the total number of pages.
So the number of pages Lourdes reads after 9 days = 30×9 = 270 pages.
Let The total number of pages in the book = y
Therefore 3/5 × y = 270.
So y = 270 × (5/3) = 450 pages.
The total number of pages in the book = 450 pages.
Lourdes will read 30 x in x days
The number of pages left = 450 - 30 x
Assume that z represents the number of pages Lourdes has left to read after x days
z = 450 - 30 x
The linear equation is z = 450 - 30 x, where z is the number of pages Lourdes has left to read after x days

What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
Given, The area of the shaded region is 39.
As the smaller rectangle is inside the whole larger rectangle,
∴The area of the smaller rectangle subtracted from the area of the whole larger rectangle is the area of the shaded region.
So, (2x - 1)(x + 3) - (x - 2)(x + 1) = 39.
2x² + 6x - x - 3 - x² - x + 2x + 2 = 39.
x² + 6x - 1 = 39.
x² + 6x - 40 = 0.
x² + 10x - 4x - 40 = 0.
x(x + 10) - 4(x + `10) = 0.
(x + 10)(x - 4) = 0.
(x + 10) = 0 Or (x - 4) = 0.
x = - 10 Or x = 4.

Between 10 P.M. and 7:54 A.M., the water level in a swimming pool decreased by 11/40 . Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?
Answer:
It approximately dropped 0.027777 per hour.
Step-by-step explanation:
First, we calculate the decrease.
Decrease = 11/40 = 0.275
Then, we calculate the time interval.
From 10 pm to 7:54 hours will be 9.54 hours
Time interval= (9 + 54/60) hours
Time interval=9.9 hours
Finally, we calculate how much it dropped each hour
0.275/9.9 ≈ 0.027777
So it approximately dropped 0.027777 per hour.
Answer:
7:54 A.M to 10 P.M is = 14 hrs and 6 mins
60 mins = 1 hour
therefore 6 mins = 0.1 hour
14 hrs plus 0.1 hrs = 14.1 hours
if 14.1 hrs = 11/40
1 HR = x
cross multiply
14.1x = 11/40
divide both sides by 14.1
14.1x / 14.1 = 11/40 / 14.1

a fair 6-sided die is repeatedly rolled until an odd number appears. what is the probability that every even number appears at least once before the first occurrence of an odd number?
The probability that every even number appears at least once before the first occurrence of an odd number is [tex]\frac{1}{20}[/tex]
Take [tex]A_{k}[/tex] - the event that odd number appeared on the k-th throw, B - every even number appeared at least once.
Let’s find P(B|[tex]A_{k}[/tex]) . Note that this probability is 0 for k∈{1,2,3} as you need k≥4 to place all distinct even numbers before the odd one.
Now for k≥4 we need to use the formula of inclusions and exclusions: P(B¯|[tex]A_{k}[/tex])=P(C2+C4+C6|[tex]A_{k}[/tex])=
=P(C2|[tex]A_{k}[/tex])+P(C4|[tex]A_{k}[/tex])+P(C6|[tex]A_{k}[/tex])−P(C2C4|[tex]A_{k}[/tex])−P(C2C6|[tex]A_{k}[/tex])−P(C4C6|[tex]A_{k}[/tex]) where Ci is the event that the dice i is missing.
These probabilities are:
P(Ci/[tex]A_{k}[/tex])=[tex](\frac{2}{3} )^{k-1}[/tex]
P(CiCj|[tex]A_{k}[/tex])=[tex](\frac{1}{3} )^{k-1}[/tex]
So
P(B|[tex]A_{k}[/tex])=1–P(B¯|[tex]A_{k}[/tex])=1−3⋅[tex](\frac{2}{3} )^{k-1}[/tex]+3[tex](\frac{2}{3} )^{k-1}[/tex].= 1 − [tex]\frac{9}{2}[/tex].[tex](\frac{2}{3} )^{k}[/tex]+9[tex](\frac{1}{3} )^{k}[/tex]

As shown in the graph, Jane has a car payment of $200 a month. Her loan amount is $3,000. Assume there is no interest.
A. What is the slope of the line?
What does this slope in this situation mean?
B. What is the y-intercept of the line?
What does the y-intercept mean in this situation?
C. How many months will it take Jane to pay off the loan?
Show your work.
Answer:
A ) What is the slope of the line? What does this slope in this situation mean?
The equation of the line is y = -200x +3000 so the slope of the line would be -200x.
This means that as x ( Month ) increases, y ( Loan ) decreases.
B ) What is the y-intercept of the line? What does the y-intercept mean in this situation?
As stated above the equation of the line is y = -200x +3000 so the y-intercept would be +3000.
In this case the y-intercept represents the cost of the loan before Jane's first payment.
C ) How many months will it take Jane to pay off the loan? Show your work.
It will take 15 months to pay off Jane's car loan.
On the graph we can see when x ( month ) equals fifteen, y ( loan ) equals zero. This means that it will take fifteen months for Jane to pay off the loan.
We can check this by putting it into our equation...
y = -200( 15 ) +3000 = 0
Hope this helps! :)

what is
S+2c=47
5s+8c=201
s=?
c=?
step by step answer
The values of the variables s and c are 13 and 17, respectively.
We are given a system of two equations. The equations are linear in nature. Each equation represents a straight line. We need to find the solution to the system of linear equations. The coordinates of the intersection point of the straight lines are the solution. The equations are given below.
s + 2c = 47
5s + 8c = 201
We will substitute the value of s from the first equation into the second equation.
s = 47 - 2c
5s + 8c = 201
5(47 - 2c) + 8c = 201
235 - 10c + 8c = 201
235 - 2c = 201
2c = 235 - 201
2c = 34
c = 17
We will substitute the value of c into the first equation to find the value of s.
s = 47 -2c
s = 47 - 2(17)
s = 47 - 34
s = 13
Hence, the values of s and c are 13 and 17, respectively.
