The congruence 64x ≡ p (mod 66) can be rewritten as the equation 64x - p = 66k, where k is an integer. We want to determine the number of solutions for x such that 0 < x < 100. To solve this congruence, we need to find the value of k that satisfies the equation. We can rewrite the equation as 64x - 66k = p. This is a linear Diophantine equation, and it can be solved using the extended Euclidean algorithm.
The extended Euclidean algorithm allows us to find the (gcd) of two numbers and express it as a linear combination of the numbers. In this case, we want to find the gcd of 64 and 66.
Using the extended Euclidean algorithm, we can find that the gcd(64, 66) = 2. This means that there are 2 solutions for x and k that satisfy the equation. To find the specific values of x, we can use the Bezout's identity.
Bezout's identity states that for any two integers a and b, there exist integers x and y such that ax + by = gcd(a, b). In our case, we have 64x - 66k = 2.
Using Bezout's identity, we can find one solution for x and k, and then find the other solutions by adding multiples of the quotient of 66 and 2 to the initial solution.
Let's say we find one solution: x₀ and k₀. Then the other solutions are given by x = x₀ + 33t and k = k₀ - 32t, where t is an integer.
To find the number of solutions between 0 and 100, we need to find the values of t that satisfy 0 < x < 100.
For t = 1, we get x = x₀ + 33 and k = k₀ - 32. If x is greater than or equal to 100, we move on to the next value of t.
By substituting different values of t, we can find the solutions for x and k that satisfy the congruence and the condition 0 < x < 100.
In conclusion, the number of solutions for x in the congruence 64x ≡ p (mod 66) such that 0 < x < 100 is equal to the number of valid values of t that satisfy the condition. The specific values of x and k can be obtained using Bezout's identity and the extended Euclidean algorithm.

Show that the following function is a bijection and give its inverse.
f : Z → N with f (n) = 2n if n ≥ 0 and f (n) = −2n − 1 if n < 0.
Let's show that the given function is a bijection and give its inverse. The function is defined as:f : Z → N with f (n) = 2n if n ≥ 0 and f (n) = −2n − 1 if n < 0. Let's consider the first condition where n is greater than or equal to 0, we have:f (n) = 2nOn the other hand, if n is less than 0, we have:f (n) = −2n − 1We need to show that the given function is one-to-one and onto to prove that it is a bijection.Function is one-to-one:Let a, b ∈ Z such that a ≠ b. Then we need to prove that f(a) ≠ f(b).Case 1: a ≥ 0 and b ≥ 0Then we have:f(a) = 2af(b) = 2bSince a ≠ b, we can say that 2a ≠ 2b. Therefore, f(a) ≠ f(b).Case 2: a < 0 and b < 0Then we have:f(a) = -2a-1f(b) = -2b-1Since a ≠ b, we can say that -2a-1 ≠ -2b-1. Therefore, f(a) ≠ f(b).Case 3: a ≥ 0 and b < 0Without loss of generality, let's assume that a > b.Then we have:f(a) = 2af(b) = -2b-1We know that 2a > 2b. Therefore, 2a ≠ -2b-1. Hence, f(a) ≠ f(b).Case 4: a < 0 and b ≥ 0Without loss of generality, let's assume that a < b.Then we have:f(a) = -2a-1f(b) = 2bWe know that -2a-1 < -2b-1. Therefore, -2a-1 ≠ 2b. Hence, f(a) ≠ f(b).Since the function is one-to-one, let's check if the function is onto.Function is onto:Let y ∈ N. We need to find an integer x such that f(x) = y.Case 1: y is even (y = 2k where k is a non-negative integer)Let x = k. Then we have:f(x) = f(k) = 2k = y.Case 2: y is odd (y = 2k+1 where k is a non-negative integer)Let x = -(k+1). Then we have:f(x) = f(-(k+1)) = -2(k+1) - 1 = -2k - 3 = 2k+1 = y.Therefore, we have shown that the given function is one-to-one and onto. Hence, the given function is a bijection.The inverse of the function f is defined as follows:Let y ∈ N. Then we need to find an integer x such that f(x) = y.Case 1: y is even (y = 2k where k is a non-negative integer)Let x = k/2. Then we have:f(x) = f(k/2) = 2(k/2) = k = y.Case 2: y is odd (y = 2k+1 where k is a non-negative integer)Let x = -(k+1)/2. Then we have:f(x) = f(-(k+1)/2) = -2(-(k+1)/2) - 1 = k = y.Therefore, the inverse of the function f is given by:f^-1(y) = k/2 if y is even.f^-1(y) = -(k+1)/2 if y is odd.

The number of students who do not buy lunch is 624 students - 420 students = 204 students.
Approximately how many pupils skip lunch at school?The circle graph represents the proportion of students who buy lunch and those who don't. To find the number of students who don't buy lunch, we need to subtract the number of students who buy lunch from the total number of students.
Since 255° represents the proportion of students who buy lunch, we can use this to find the number of students who buy lunch. To do this, we divide the number of degrees by 360° and multiply by the total number of students, 624:
(255° / 360°) x 624 students = 420 students
Therefore, the number of students who do not buy lunch is 624 students - 420 students = 204 students.

1.What tool ensures greater accuracy by aligning the graduated scale with the edges or points to be measured
The tool that ensures greater accuracy by aligning the numbers scale with the edges or points to be measured is a Vernier caliper.
A Vernier caliper is a tool used to accurately measure small lengths, widths, and diameters with precision. It has two parts: an outer frame and a sliding vernier scale. The frame is used to place the object to be measured, while the vernier scale is moved along the frame to measure the object's length.
The graduations on the vernier scale are smaller than the main scale graduations, allowing for more precise measurements to be made. This makes the Vernier caliper a more accurate measuring tool than a standard ruler or tape measure.

Simply use cross multiplication :
The process of multiplying numbers in the shape of a fraction is called cross multiplication. Cross multiplying, also known as cross multiplication, is the process of multiplying the numerator of one fraction by the denominator of the other fraction on the other side of an equal symbol. Cross multiplication is a method for comparing fractions.
Both fractions with like and unlike parts are multiplied across. When employing the cross-multiplication procedure, we multiply the denominators as well as the numerators when a fraction is dissimilar, or when the denominators of two fractions are not alike.

After living in a university residence for one year, Alysha decides to rent an apartment for the remaining three years of her degree. She has found a nice location that will cost $850 per month. Rent for the first and last month must be paid up front. How much money would Alysha need to have in her bank account right now to be sure she will always have enough for rent? The bank account pays 3.0 percent interest, compounded monthly.
Alysha would need approximately $34,234.59 in her bank account right now to be sure she always has enough for rent.
To calculate how much money Alysha would need in her bank account, we need to consider the monthly rent of $850 and the requirement to pay the first and last month's rent up front.
Since Alysha is renting for three years, she will need to pay rent for 36 months. This means she will need to have enough money to cover 36 months of rent.
To calculate the future value of her required funds, we can use the formula for compound interest:
Future Value = Present Value * (1 + interest rate)ⁿ
Here, the present value is the total amount of rent Alysha needs to cover (36 * $850), the interest rate is 3.0% (or 0.03), and n is the number of compounding periods (36).
Using the formula, the future value of Alysha's required funds would be:
Future Value = (36 * $850) * (1 + 0.03)³⁶
Simplifying this calculation, Alysha would need approximately $34,234.59 in her bank account right now to be sure she always has enough for rent.

Victoria and Michael paid a $150 application deposit for an apartment. Their monthly rent is $2,200. They are required to provide a credit report that costs $35 and pay a security deposit equal to 1 month’s rent. The first and last month’s rent are due at the time of signing the lease. The broker charged 2.5% of the yearly rent. Find the cost to move in.
The cost to move in for Victoria and Michael is $7,645.
The cost to move into the apartment for Victoria and Michael can be found by calculating the sum of the application deposit, credit report cost, security deposit, first and last month's rent, and the broker fee.
Using the given information:
$150 is the application deposit
$35 is the cost of the credit report
Security deposit is 1 month's rent which is $2,200
First and last month's rent are also $2,200 each.
Thus, the total amount for these two months will be $4,400
The broker charged 2.5% of the yearly rent.
The yearly rent is $2,200 × 12 months = $26,400.
Therefore, the broker fee will be 2.5% of $26,400 which is $660.
Total cost to move in = $150 + $35 + $2,200 + $2,200 + $660 + $2,200 = $7,645
Therefore, the cost to move in for Victoria and Michael is $7,645.

3(y – 2) + 2(y – 2)
= 3y – 6 + 2y – 4
= 5y – 10
Now let's simplify 5(y-2):
5(y-2)
= 5y – 10
As we can see, both expressions simplify to the same expression, 5y – 10. Therefore, the expressions 3(y – 2) + 2(y – 2) and 5(y-2) are equivalent.
This is important in algebra because it allows us to manipulate expressions and equations without changing their meaning or solutions. We can replace one expression with an equivalent one to make it easier to work with or to solve an equation.The expressions 3(y – 2) + 2(y – 2) and 5(y-2) are equivalent because when simplified, they both result in the same mathematical expression.

3y - 6 + 2y - 4.
Now, combine like terms:
3y + 2y = 5y and -6 - 4 = -10.
So, the simplified expression is 5y - 10.
For the second expression, 5(y-2), distribute the coefficient:
5y - 10.
As you can see, both expressions simplify to 5y - 10, making them equivalent.
