A counterexample that disproves her conjecture is that Easter date fell outside the first 22 days in April in the year 2024, 2027, 2032 and 2038.
Easter Sunday might come between March 22 and April 25. Easter is always celebrated on the Sunday immediately following the Paschal Full Moon date of the year. The Paschal Full Moon is the first Ecclesiastical Full Moon date after March 20. So, in Western Christianity, Easter is always celebrated on the Sunday immediately following the Paschal Full Moon.
Her conjecture over 2018 to 2021 is not a full reflection of the changes that occurs in these dates. To draw a more concrete assumptions, a wider range of year would need to be considered. Hence, the date variations between 2018 and 2021 is not enough for such conjectures.

For A-D, select each fraction that is equal to 4 5
The fractions 16/20, 12/15, and 8/10 are equivalent fractions to 4/5.
When writing equivalent fractions, the numerator and denominator should be multiplied or divided by the same number. This is the reason why when these fractions are simplified, they are reduced to the same value.
Let us understand the two ways in which we can make equivalent fractions:
Now, Divide the denominator or numerator by the same number or multiply the denominator and the numerator by the same number.
So, the equivalent fractions for 4/5 are:
(4/5) × (2/2) = (4 × 2) / (5 × 2) = 8/10
(4/5) × (3/3) = (4 × 3) / (5 × 3) = 12/15
(4/5) × (4/4) = (4 × 4) / (5 × 4) = 16/20
After simplifying, 16/20, 12/15, and 8/10 equal 4/5, indicating that they are identical in nature.

What single decimal multiplier would you
use to increase by 9% followed by a 6%
decrease?
There will be a 6% rise using the 0.9646 multiplier, then a 9% reduction.
What is a multiplier?Simply said, a multiplier is a factor that increases the basic value of another object. For example, a 2x multiplier would double the initial value. On the other hand, a multiplier of 0.5x would actually cut the basic amount in half. In finance and economics, multipliers come in a wide variety.
Say that Number is 100N.
growth of 6%
= (6/100)100N
= 6N
Number following reduction: 100N + 6N = 106N
9% lessening
= (9/100)106N
=954N/100
= 9.54N
Final result after reduction = 106N - 9.54N
=96.46N
=9646N/100
= 9646 * 100N/100 * 100
= 9646 * 100N/10000
= 0.9646 * 100N
There will be a 6% rise using the 0.9646 multiplier, then a 9% reduction.

A garden is in the shape of a square with a perimeter of 60 feet. The garden is surrounded by two fences. One fence is around the perimeter of the garden, whereas the second fence is
2 feet from the first fence on the outside. If the material used to build the two fences is $1.21 per foot, what was the total cost of the fences?
The total length between the two fences is 136 ft, and the total cost is 164.56 dollars.
What was the total cost of the fences?We have a square garden with a perimeter of 60ft. Then if the sidelength of the square is S, we have that:
60ft = 4*S
S = 60ft/4 = 15ft
We know that the first fence is around the perimeter of the garden, so the length of the first fence is exactly 60ft.
Now, the other fence is 2ft away from the first fence, so it forms a square of sidelength of:
15ft + 2*2ft = 19ft
Then the perimeter of this square is:
P = 4*19ft = 76ft
This means that the length of the second fence is 76 ft.
So the total length of fence is 76ft + 60ft = 136ft
And the cost is $1.21 per ft, then the total cost for the fence is:
C = 136*$1.21 = $164.56

By applying the distributive property, the equivalent expression to 3v - (7.9w - 9.3) is: 3v - 7.9w + 9.3.
What is an Equivalent Expression?Two expressions are equivalent if they both have equal values when simplified or evaluated.
How to Apply the Distributive Property?To apply the distributive property, the term or operation sign outside the parentheses is used to multiply each of the terms that are within the parentheses.
Given the expression, 3v - (7.9w - 9.3)
Apply the distributive property to find an equivalent expression
3v - (7.9w - 9.3) = 3v -(7.9w) - (-9.3)
3v - (7.9w - 9.3) = 3v - 7.9w + 9.3

A jar contains 0.25 liter of apple juice and 0.30 liter of grape juice. Melissa poured 0.75 liter of pineapple juice into the jar. She then drank 0.20 liter of the mixture.
Part A: Write an expression to represent the total amount of juice left in the jar.
Part B: Simplify the expression and identify which property is used in each step.
Part A: Expression to represent the total amount of juice left in the jar : (0.25 +0.30 + 0.75) - 0.20
Part B: Simplifying above expression using properties of addition and subtraction gives that total amount of juice left is 1.1 liter.
What is an expression?An expression is a group of terms consisting of numbers and mathematical operators ( +, -,*,/) and "=" is not there.
Given that a jar contains 0.25 liter of apple juice, 0.30 liter of grape juice, 0.75 liter of pineapple. Melissa then drank 0.20 liter of the mixture.
Therefore, total juice in the jar before Melissa drank it = quantity of (apple juice + grape juice + pineapple juice ) = (0.25+ 0.30+0.75) liters
After Melissa drank 0.20 liter juice left = total juice before - 0.20
Thus, Expression to represent the total amount of juice left in the jar is: (0.25 +0.30 + 0.75) - 0.20
And it can be solved as (0.25 +0.30 + 0.75) - 0.20 = (0.55+0.75)-0.20
= 1.30-0.20 = 1.1 liter
Thus, after simplifying expression we get that the left juice in the jar is 1.1 liter.

The axis of the cylinder is a line drawn through the centre or connecting the centres of two circular bases. The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder. Any substance that can fill the cylinder consistently with liquid or another material may be used as the component.

The result of simplifying each number 1000⁴/₃ / 100³/₂ using the exponent rules is: 10
To solve this exercise we have to resolve algebraic operations following the exponent rules.

If you have applied for two jobs a and b and the probability that you get an offer for the job a is 0.25 and the probability of being offered job b is 0.20, then the probability that you will be offered both jobs is 0.05.
Probability is a term used in mathematics that is concerned with the numerical illustration of the possibility of an event to take place. Its value is between 0 and 1 where 0 illustrates the impossibility of the event to take place while 1 illustrates the certainty of an event to take place.
As the probability of both the jobs are not dependent on each other, the probability that both jobs will be offered can be calculated by the formula;
P(A∩B) = P(A) × P(B)
Here, P(A∩B) represents the probability of both the events to take place together
As P(A) is equal to 0.25
P(B) is equal to 0.20
P(A∩B) = (0.25)(0.20)
P(A∩B) = 0.05

B. f(a + h) = 9a + 9h - 9.
C. f(a + h) - f(a) = 9h.
D. (f(a + h) - f(a))/h = 9.
How to find the numeric value of a function/expression?To find the numeric value of a function, we replace each instance of the variable by the desired value.
For this problem, the function is given by:
f(x) = 9x - 9.
At x = a, the numeric value is given by:
f(a) = 9(a) - 9 = 9a - 9.
Hence:
f(a) = 9a - 9.
At x = a + h, the numeric value is given by:
f(a + h) = 9(a + h) - 9 = 9a + 9h - 9.
Hence:
f(a + h) = 9a + 9h - 9.
Subtracting these values, we have that:
f(a + h) - f(a) = 9a + 9h - 9 - 9a + 9 = 9h.
Hence:
f(a + h) - f(a) = 9h.
Dividing by h, we have that:
(f(a + h) - f(a))/h = 9h/h = 9.
Hence:
(f(a + h) - f(a))/h = 9.

When 4 nightstands are sold the profit is $1800 since the number of nightstands sold is directly proportional to the profit.
The profit is defined as difference between the cost price and sell price for a product.
A directly proportional relationship means that if two variables x and y are proportional to one another then there exist a constant k such that x = y × k .
The graph of a directly proportional equations is a straight line passing through the origin.
Given that the profit is $900 for 2 sold nightstands, $3600 for 8 night stands and $4500 for 10 sold nightstands.
Now this relationship is directly proportional.
So the constant is given by k=900/2=4500/10=3600/8=450
Hence the profit for selling 4 night stands is 450 × 4 =$1800
