Answer:
Step-by-step explanation: Since there are 7 people who shake hands with everybody including the people who know each other, we can add 11+10+9+8+7+6+5, because each handshake counts once, but the other five can't be counted because they are the people who already know each other and if you add 11+10+9+8+7+6+5, you will also get 16*3 +8 which equals to 56.
Karla is selling tickets for a high school play. Child tickets cost $7 and adult tickets cost $13 she sells 180 tickets and collects $1830 Setup a system of equations using C for number of child tickets and A for number of adult tickets to find the number of each ticket sold
Answer: The number of child tickets is 85 and the number of adult tickets is 95.
Step-by-step explanation:
Let C = Number of child tickets
A = Number of adult tickets.
As per given, we have
C+A=180 (i)
7C+13A=1830 (ii)
Multiply 7 to both sides of equation (ii), we get
7C+7A=1260 (iii)
Eliminate (iii) from (ii) , we get
[tex]6A=570\\\\\Rightarrow\ A=95[/tex]
Put value of y in (i), we get
C= 85
Hence, the number of child tickets is 85 and the number of adult tickets is 95.
Every three years the population of one part of Brooklyn is recorded.
In 2014 there was a population of 10,500 people.
From 2014 to 2017 the population increased by 22%.
From 2017 to 2020 the population decreased by 10%.
What was the population of this area in 2020?
Answer:
11,529
Step-by-step explanation:
10500x22%=2310
10500+2310=12810
12810x10%=1281
12810-1281=11529
Answer:
Hello there!
Your question asks to find what was the size of the population in 2017
Answer: 6,721
In order to solve this problem, we're going to need to use the given information in the question in order to find the population in 2017.
Key information:
In 2010, population was 6500
In 2014, population increased by 10% from 2010
In 2017, population decreased by 6% from 2014.
With the information above, we can solve the problem.
We're going to start with 6500 as our starting population.
We know that the population increased by 10% in 2014, so we would multiply 6500 by 1.10.

of a football team's season touchdowns, about 43% came by passing. If the team scored 28 touchdowns, how many were by other means?
43% were from passing so 100% - 43% = 57% came by other means.
28 x 57% = 28 x 0.57 = 16
16 came from different means.

Boden's account has a principal of $300 and a simple interest rate of 3.8%. Complete the number line. How much money will be in the account after 4 years, assuming Boden does not add or take out any money?
Answer:$66.00
Step-by-step explanation:
first we need multiply :D I will use the formula I =prt
principal= $500
rate=3.3%
time= 4 years
but we need to convert the percent, 3.3%, to a decimal
3.3%=0.033 or .033
then we multiply
500 × 0.033 × 4 = 66 = $66.00

What is a formula for the nth term of the given sequence?
36, -48, 64...
Answer:
A formula for the nth term of the given sequence is:
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
Step-by-step explanation:
Given the sequence
36, -48, 64...
We know that a geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
Compute the ratios of all the adjacent terms
[tex]\frac{-48}{36}=-\frac{4}{3},\:\quad \frac{64}{-48}=-\frac{4}{3}[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=-\frac{4}{3}[/tex]
Therefore, the given sequence is a geometric sequence.
As the first element of the sequence is
[tex]a_1=36[/tex]
so substituting [tex]a_1=36[/tex] and [tex]r=-\frac{4}{3}[/tex] in the nth term
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]
Therefore, a formula for the nth term of the given sequence is:
[tex]a_n=36\left(-\frac{4}{3}\right)^{n-1}[/tex]

3. Given the statement "x - 4 is a factor of f(x)= 5x* – 22x - 2x2 – 25x +4". explain how to verify the
statement is accurate.
Step-by-step explanation:
x - 4 = 0
=> x = 4
f(x)= 5x – 22x - 2x² – 25x +4
By remainder theorem,
f(4)= 5(4) – 22(4) - 2(4)² – 25(4) + 4
= 20 - 88 - 32 - 100 + 4 ≠ 0
Since the remainder is not 0, x - 4 is not a factor.

1. E = -20,000p + 90,000
R = -2,170p2 + 87,000p
The equations of E and R are illustrations of cost and revenue functions
The equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p
How to determine the break even pointThe cost and the revenue functions are given as:
E = -20,000p + 90,000
R = -2,170p^2 + 87,000p
At the break even point, we have:
E = R
Substitute known values
-20,000p + 90,000 = -2,170p^2 + 87,000p
Hence, the equation of the break even point is -20,000p + 90,000 = -2,170p^2 + 87,000p

The terms in the sequence decrease by the same amount each time:
9, 6 ,3 ,0, -3, -6
Work out ,in term of n, the nth term of the sequence
Answer:the nth term of the sequence, Tn= -3n +12
Step-by-step explanation:
The nth term of an arithmetic progression is given as
Tn= a+ (n-1) d
where a= first term
and d = common difference
In this sequence, 9, 6 ,3 ,0, -3, -6 we can see that the number is decreasing by 3
The first term, a= 9
and common difference, d = -3
using our formulae
Tn= a+ (n-1) d
Tn= 9 + ( n-1) -3
Tn=9- 3n+ 3
Tn= -3n +12

Given the equation find the y-intercept. Write it as a coordinate ( 0 , y ).
y=-4x+3
Answer:
(0, 3)
Step-by-step explanation:
The equation already shows the y-intercept (written as +3). The slope is -4x and the y-intercept is (0, 3).
Answer:
y=3
Step-by-step explanation:
Because we know x equals 0 we put that into the equation so then you have y=4(0)+3 you multiply 4 time 0 and get 0 so all you have left is 3.
