The number of hours the polls open on the election day was 9 hours
From the question, we are to determine how long the polls opened on the election day
From the given information,
6,504 people vote in the advance polls for a riding prior to the election
and
A total of 10,167 people voted in that riding
Thus,
The number of people that voted on the election day = 10167 - 6504
Number of people that voted on the election day = 3663
Also, from the given information
The polling stations for the riding record an average of 407 voters per hour
Then,
Number of hours the polls open on election day = Number of people that voted on the election day ÷ Average number of voters per hour
Number of hours the polls open on election day = 3663 ÷ 407
Number of hours the polls open on election day = 9 hours
Hence, the number of hours the polls open on the election day was 9 hours

earle bailey has 20 songs to choose from but can play only 7 in the next half‑hour on siriusxm classic vinyl. how many different (ordered) playlists are possible? (use decimal notation. give your answer as an exact number.)
The answer is 77520.
What is meant by decimal notation?Decimal notation is an alternative way to represent fractional values in mathematics. This indicates that base 10 is being used for the fractional representation. Both the fractions and decimals can be transformed. For instance, the decimal representation of the fraction 5/10 is 0.5.Any value between 1.0 and 10.0 that can be expressed as a decimal number and multiplied by a power of 10 is considered standard form. If you look closely, you will see that 1.23 is a decimal between 1.0 and 10.0, and as a result, we have the standard form of 123,000,000 as 1.23 108.Because they represent a portion of a whole number, decimals are equivalent. The distinction is that fractions and decimals are written using different notations. We can visually estimate how much of a full number we are working with thanks to decimal notation.How many different (ordered) playlists are possible?
Number of possible playlists = 77520
Explanation:
Total number of songs = 20
Songs in the playlist = 7
So, we need to select 7 songs out of 20. This can be done using combinations.
n = 20 , r=7
C( n , r ) = ?
C( n , r ) = C (20 , 7)
= 20! / ( 7! (20-7)!)
= 20! / ( 7! × 13! )
= 77520

For each function, identify the transformation from the parent function y=b x . y=7 (x-5)
Transformation of y= bx into y=7(x-5) will take place by by horizontal translation by 5 units to the right, vertical dilation by a scale factor of 7 .
A parent function is the simplest form of a particular family of functions. A family of functions is a group of functions that have the same highest degree and therefore the same graph shape. Function transformations "move" or "resize" or "mirror" the graph of the parent function. Mathematically speaking, the transformation of the function y = f(x) is usually y = a f(b(x + c)) + d. where a, b, c, and d are arbitrary real numbers representing transformations. Note that all outer numbers (outside the brackets) represent vertical translations, and all inner numbers represent horizontal translations. Addition and subtraction are translations, and multiplication and division are dilations. Every time a minus sign is multiplied it means it is a reflection here, 'a' stands for vertical stretch , 'b' stands for horizontal stretch , 'c' stands for horizontal movement , 'd' stands for vertical movementWe have given two function y=b x and y=7 (x-5) which means that first y changes into (x -5 ). i.e., horizontal translation by 5 units to the right. Then it changes into 7 (x - 5). i.e., vertical dilation by a scale factor of 7.

What is the logarithmic form of each equation?
c. 1=3⁰
The logarithmic form of the given equation is log₃(1) = 0.
A logarithm is the degree to which a number must be raised in order to produce another number. For instance, the logarithm of 100 in base ten is 2, since ten multiplied by two equals 100: log 100 = 2, since 10² = 100.
The given equation is 1 = 3⁰
To convert this exponential form into logarithmic form, we are required.
Consider the given exponential form:1 = 3⁰
Taking logarithm on both sides with the base as 3, we get,⇒ log₃(1) = log₃(3⁰)
Now using the logarithmic rule logₐ(aⁿ) = n × logₐ(a) in the RHS of the above equation, we get
⇒ log₃(1) = 0 × log₃(3)
⇒ log₃(1) = 0 (Because 0 multiplied by any number equals zero,)
Therefore, the value of 1 = 3⁰ is given by log₃(1) = 0.

Write the equation of the line passing through the points (-4,5) and (-5,4)
Answer:
y=x+9
Step-by-step explanation:
The general equation for a straight line is y=mx+c
1. first we need to find the gradient (m) to do this we do
4-5/-5-(-4)
which gives the answer of 1. This means or gradient (m) is 1. we can substitute this in our general formula y=mx+c which gives
y=1x+c this can also be written as y=x+c
2. we need to find the value of c. to do this we can sub in any co-ordinates from the question in this case we will be using (-4,5)
-4 is the x co-ordinate
5 is the y co-ordinate
5= -4+c
to get c we add 4 on each side we get
9=c
we can sub this into the equation we produced with the gradient giving us
y=x+9
3. the final answer is y=x+9
Hattie had $1800 to invest and wants to earn 2.4% interest per year. She will put some of the money into an account that earns 2.3% per year and the rest into an account that earns 3.5% per year. How much money should she put into each account?
The amount invested in the account with 2.3% interest is $1650 whereas $150 was invested in the account whose interest rate is 3.5%
What is Hattie's annual earnings on the investment of $1,800?
The earnings that Hattie would receive every year on the investment is $1,800, the investment multiplied by the expected rate of return of 2.4%
annual earnings=$1,800*2.4%
annual earnings=$43.20
Let the amount invested at 2.3% to be x and the amount invested at 3.5% would be (1800-x), hence, the interest earnings are shown thus:
interest on 2.3% investment=x*2.3%=0.023x
interest on 3.5% investment=(1800-x)*3.5%
interest on 3.5% investment=63-0.035x
total interest=0.023x+63-0.035x
total interest=63-0.012x
43.20=63-0.012x
0.012x=63-43.20
0.012x=19.80
x=19.80/0.012

Tristan wants to build a square garden in his backyard that will cover an area of 75ft(squared). If Tristan has 32 feet of material for the perimeter of the garden, does he have enough? Explain
The 32 feet of the material for the perimeter of the garden is not enough as the perimeter of the garden is 34.64 feet.
We are given that:
Area of a square garden = 75 feet²
Let the side of the square garden be x
x² = 75
x = √ 75
x = 5 √3 feet
Perimeter of the square garden = 4 × x feet
Perimeter = 4 × 5 √ 3 feet
Perimeter = 20 √ 3 feet
P = 34.64 feet.
Now, Tristan only has 32 feet of material.
So, the material is not enough.

if there are "n" packets of Jelly tots. The chocolates are three more than 4 times the Jelly Tots Write down an algebraic expression for the number of chocolates.
Answer:
3+(4x)
Step-by-step explanation:
The algebraic expression will be written as:
x=jelly tots
The number of chocolates=3+(4×x)
=3+(4x)
The algebraic expression for the number of chocolates is 4n + 3 where n is number of packets of Jelly Tots.
Let's use variables to represent the number of Jelly Tots and chocolates:
Let "n" be the number of packets of Jelly Tots.
Now, the number of chocolates is three more than 4 times the number of Jelly Tots.
So, represent the number of chocolates as:
Number of chocolates = 4 * n + 3
4 * n represents 4 times the number of Jelly Tots.
Multiplying the number of Jelly Tots by 4 gives us the chocolates without the additional 3.
- +3 represents the additional chocolates.
Thus, the algebraic expression is 4n + 3.

There is a 5% sales tax on the selling price. What is the total cost to the customer?
The total cost to the customer is $8.86.
What Are Taxes?Taxes are mandatory contributions levied on individuals or corporations by a government entity—whether local, regional, or national.
Given:
Logo shirts at a cost of $10 per shirt.
Every month that a shirt doesn’t sell, the store reduces the selling price by 25%.
There is a 5% sales tax on the selling price.
According to given question we have
Cost of shirt = $10
Cost of the shirt after 100% increase
=100% of 10
= $10
Price of shirt after 100% increase
= $10 + $10
= $20
if shirt does not sell, price reduces by 25%. It means remaining value is 75% after every reduction.
So after 3 reductions, remaining value is 75% after every reduction
So, final price will be
$20 * 0.75 * 0.75 * 0.75
= $8.4375
There is a sales tax of 5% which customer will pay on the final price.
So, price for customer will be
$8.4375 + (5% of 8.4375)
