The people at a party tried to form teams with the same number of people on each team, but when they tried to split up into teams of 2, 3, 5, or 7, exactly one person was left without a team. What is the smallest number of people (greater than $\color[rgb]{0.35,0.35,0.35}1$) who could have been at the party?
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.

The equations that represent the left side, right side, top side and bottom side are y = 3x+2, y = 3x-10, y = 5 and y = -1 respectively
How to write the equation that represents each side of the figure?The slope-intercept form of the equation of a line is y =mx+c,
where m is the slope and c is the y-intercept
slope(m) = y2-y1 / x2-x1
Left side
The line moves from point 1 (-1, -1) to point 2 (1,5)
x1 = -1, y1 = -1 and x2 = 1, y2 = 5
Slope(m) = 5-(-1) / 1-(-1) = 6/2 = 3
Using the equation of a line for 2 points:
y-y1 = m(x-x1)
y-(-1) = 3(x-(-1))
y+1 = 3(x+1)
y+1 = 3x+3
y = 3x+2
Right side
The line moves from point 1 (3, -1) to point 2 (5,5)
Slope(m) = 5-(-1) / 5-3 = 6/2 = 3
y-(-1) = 3(x-3)
y+1 = 3x -9
y = 3x-10
Top side
y = 5
Bottom side
y = -1

$15 a share. A month later, it was
selling at $27 a share. What is
the percent increase?
Answer: 0.555555556
Step-by-step explanation:
15/27=0.555555556
Checking work by plugging it in: 27x0.555555556=15
======================================================
Work Shown:
a = old value = 15
b = new value = 27
c = change in values
c = b-a
c = 27-15
c = 12
The positive c value tells us that we have an increase.
Then divide over the starting value a = 15
c/a = 12/15 = 0.80
Move the decimal point two spots to the right to go from 0.80 to 80%
Or multiply 0.80 with 100% to get 0.80*100% = 80%
We have a percent increase of 80%
-------------------
Check:
80% of 15 = 0.80*15 = 12
If the stock increases by 80%, then it has increased by $12 to go from $15 a share to 15+12 = 27 dollars a share. This confirms the answer.
A slight shortcut would be to say 1.80*15 = 27
The multiplier 1.80 represents an increase of 80% since 100% + 80% = 1 + 0.80 = 1.80
What is the slope of a line that is parallel to the line y = x + 2?
Mark this and return
The slope of a line that is parallel to the line y = x + 2 is 1.
What is slope?
A line's steepness is determined by its slope. In mathematics, the slope is determined by "rise over run" (change in y divided by change in x).
Given the equation of line: y = x + 2
We have to find the slope of a line that is parallel to the given line.
Since any line parallel to the given line y = x + 2 will have the same slope as that of a given line
The general equation of line is given as y = mx + c
where. m is the slope of the line and c is y-intercept.
Thus for given equation of line y = x + 2
Comparing , we get
slope is m=1
Thus, any line with slope 1 is parallel to the given line y = x + 2

Assuming you choose at least one coin, how many different sets of coins can you form? b. Assuming you choose at least one coin, how many different sums of money can you produce? c. Explain why the answers in part a and part b are not the same.
As per the concept of counting problem, the reason that the answers in part (a) and part (b) are not the same is because Q1 and Q2 are treated as two different coins in part (a) whereas they are effectively treated as the same coin in part (b). And the reason they are treated as one coin is because they both contribute the same amount to the sum of money.
Counting Problems
Basically, counting refers the process of finding the number of elements of a finite set of objects.
Given,
Suppose you have a nickel, two dimes, and a quarter. One of the dimes was minted in 1976, and the other one was minted in 1992.
While we looking into the given problem,
For A) states that, If you choose at least one coin, this means you could choose 1, 2, 3 or 4 coins. Let us label the dime as D, the penny as P, the quarter minted in 1976 as Q1 and the quarter minted in 1992 as Q2.
Here in this process if you choose one coin, you could choose either D, P, Q1, or Q2. This gives us 4 possible sets.
And If you choose two coins, you choose the following sets of coins: DP, DQ1, DQ2, PQ1, PQ2, Q1Q2. This gives us 6 possible sets.
Then If you choose three coins, you could the following sets of coins: DPQ1, DPQ2, DQ1Q2, PQ1Q2. This gives us 4 possible sets.
So, If you choose four coins, you can only choose DPQ1Q2. This gives us 1 possible set.
So, the total number of different sets of coins you can form is 4 + 6 + 4 + 1 = 15 different sets of coins can be formed.
Similarly, for b) If you choose at least one coin, this means you could choose 1, 2, 3 or 4 coins.
Then If you choose one coin you could choose either D, P, Q1, or Q2. However, since Q1 and Q2 give us the same sum, they are effectively the same set. This gives us 3 possible sums.
So, If you choose two coins, you could choose the following sets of coins : DP, DQ, PQ, Q1Q2.And this gives us 4 possible sums
Then If you choose three coins, you could choose the following sets of coins: DPQ, DQ1Q2, PQ1Q2. And this gives us 3 possible sums
Then If you choose four coins, you can only choose DPQ1Q2. This gives us 1 possible sum.
So, the total number of different sums of coins you can form is 3 + 4 + 3 + 1 = 11 different sums of money can be produced.
Finally, c) The reason that the answers in part (a) and part (b) are not the same is because Q1 and Q2 are treated as two different coins in part (a) whereas they are effectively treated as the same coin in part (b). And the reason they are treated as one coin is because they both contribute the same amount to the sum of money.

An oil company fills 1 over 12 of a tank in 1 over 3 hour. At this rate, which expression can be used to determine how long it will take for the tank to fill completely? (1 point)
a
1 over 12 • 3 hours
b
1 over 3 • 12 hours
c
1 over 3 • 1 over 12 hour
d
3 • 12 hours
Answer:
B. 1 over 3 x 12 hours
Step-by-step explanation:
The oil company fills 1/12 of a tank in 1/3 an hour. So, you multiply 1/3 times 12, since 12 is a full tank. It'll take 4 hours to fill the tank at this rate.

[tex]\implies \dfrac{180^{\circ}(5-2)}{5}=\dfrac{180^{\circ}(3)}{5}=\dfrac{540^{\circ}}{5}=108^{\circ}[/tex]
If "a" is the measure of one angle, and m∠a = (3z + 72)° then:
[tex]\implies m \angle a=108^{\circ}[/tex]
[tex]\implies (3z+72)^{\circ}=108^{\circ}[/tex]
[tex]\implies 3z+72=108[/tex]
[tex]\implies 3z+72-72=108-72[/tex]
[tex]\implies 3z=36[/tex]
[tex]\implies \dfrac{3z}{3}=\dfrac{36}{3}[/tex]
[tex]\implies z=12[/tex]
