For how many different displays, starting at 10:00 AM and ending at 4:00 PM, during a particular day, will a digital clock show that the number of the hour is less than the number of the minute? [For example, at 2:15 the number of the hour is less than the number of the minute but at 2:01, the number of the hour is greater than the number of the minute]
A digital clock will show that the number of the hour is less than the number of the minute for 12 different displays, starting at 10:00 AM and ending at 4:00 PM.
What will the clock display?These displays are:
10:01 AM, 10:12 AM, 10:23 AM, 10:34 AM, 10:45 AM, 11:02 AM, 11:13 AM, 11:24 AM, 11:35 AM, 12:03 PM, 12:14 PM, and 12:25 PM.
For example, 10:01 AM and 11:23 AM.
From 10:00 AM to 12:59 PM, the hour will always be a single digit, so we can check the minutes to see if they are double digit.
From 10:00 AM to 10:59 AM, the minute has to be greater than the hour. So, we can pick the minutes starting from 01 to 59 and check whether the hour is less than the minute which gives us 12 such displays

Each of 36 students at a school play bought either a cup of orange juice or a sandwich. A cup of orange juice costs $1 and a sandwich costs $3. The total amount collected was $76. How many students bought orange juice, and how many bought a sandwich?
Let x represent the number of students who bought a cup of orange juice and y represent the number of students who bought a sandwich. Then the problem can be represented by this system of equations:
x + 3y = 76
x + y = 36
Answer the questions to solve the problem.
1. Explain what you should do with the two equations to eliminate one of the variables. (2 points)
2. Find the value of y. (3 points)
3. Find the value of x. (2 points)
4. Interpret the solution and check the values in the system. (3 points)
Answer:
see explanation
Step-by-step explanation:
given the system of equations
x + 3y = 76 → (1)
x + y = 36 → (2)
1
subtracting (2) from (1) term by term will eliminate x
(x - x) + (3y - y) = 76 - 36
0 + 2y = 40
2y = 40 ( divide both sides by 2 )
y = 20
3
substitute y = 20 into either of the 2 equations and solve for x
substituting into (2)
x + 20 = 36 ( subtract 20 from both sides )
x = 16
4
that is 16 students bought orange juice and 20 bought a sandwich
As a check
substitute the values for x and y into the equations and if both sides are equal then they are the solution
(1) : 16 + 3(20) = 16 + 60 = 76 ← True
(2) : 16 + 20 = 36 ← True
since both equations are true, then
x = 16 and y = 20 are the solutions to the system

What is a 3 2 image ratio?
A 3:2 image ratio refers to the proportion of the width to the height of an image or screen. It means that for every 3 units of width, there are 2 units of height.
The aspect ratio 3:2 is commonly used in digital photography, particularly for DSLR cameras and some mirrorless cameras.
In photography, the 3:2 aspect ratio is considered a standard format, it's the same as the traditional 35mm film frame, it's also the same as the aspect ratio of most modern digital cameras. It allows photographers to capture a wide range of scenes and subjects, and it's also a good option for cropping and printing photos.
For example, if an image's resolution is 3000x2000 pixels, it means that it has a 3:2 aspect ratio. The width of the image is 3000 pixels and the height is 2000 pixels, so 3000/2000 = 3/2
It's worth noting that the aspect ratio of 3:2 is a compromise between the wider aspect ratio of 16:9, used for video and some photography, and the taller aspect ratio of 4:3, used for more traditional photography.

f(x) =(x - 5)/3 find the inverse function of this
The inverse function of f(x) = (x - 5)/3 is f^-1(x) = 3x + 5.
What is inverse function? How to calculate it? In mathematics, an inverse function is a function that undoes the work of another function. Specifically, if the function f applied to an input x gives a result of y, then the inverse function of f, denoted as f−1, applied to y gives the result x. In other words, the inverse of the function "f" applied to y will give us the input that we originally used to obtain y.To calculate an inverse function, one must first identify the original function. Then, one must switch the x and y variables, and solve for y. This is done by isolating the y in the equation and replacing it with the inverse function. For example, if the original equation is y = x + 4, then the inverse equation is x = y - 4.Once this is done, one can then determine the inverse function by taking the reciprocal of the function. This can be done by changing the sign of the exponent for any exponentiated terms and changing the sign of the coefficient for any multiplied terms. For example, if the function is y = x2 + 2x + 4, then the inverse function is y = (1/x2 + 2/x + 4)−1.In summary, to calculate an inverse function, one must first identify the original function, switch x and y, and solve for y, and then take the reciprocal of the expression.Solution:
To find the inverse of a function, we need to switch the x and y variables, and then solve for y.
Starting with f(x) = (x - 5)/3, we can switch the x and y variables to get y = (x - 5)/3.
We can then solve for x by multiplying both sides by 3, giving us 3y = x - 5.
We can then add 5 to both sides to get 3y + 5 = x, which is the inverse of our original function.
Therefore, the inverse of f(x) = (x - 5)/3 is f^-1(x) = 3x + 5.

What is the similarity of polygons?
The similarity of polygons refers to the relationship between two or more polygons in which the corresponding angles are congruent (equal in measure) and the corresponding side lengths are in proportion.
We have,
Polygon 1:
Opposite Sides 24 = 24, 12=12,
Angles = 90°
Polygon 1:
Opposite Sides 16 = 16, 8=8,
Angles = 90°
This means that if two polygons are similar, their corresponding angles will have the same measure, and their corresponding side lengths will be in the same ratio. In other words, the ratio of any pair of corresponding sides of similar polygons will be the same.
For example, two triangles are similar if the ratio of their corresponding sides is the same, and their corresponding angles are equal. Similarly, two quadrilaterals are similar if the ratio of their corresponding sides is the same and their corresponding angles are equal.
It's important to note that similarity is a stronger relationship than congruence, because in congruence all the sides and angles must have the same measure, while in similarity only the angles and ratios of sides are the same.
Additionally, the similarity of a polygon can be determined by measuring the angles of the polygon, and comparing the ratios of the corresponding sides.
If the angles are congruent and the ratios are equal, then the polygons are similar.
Hence, the angles are congruent and the ratios of sides are equal, then the polygons are similar.

The 4 types of triangle with respect to angle measurement :
Acute Triangle
Obtuse Triangle
Right triangle
Equivalent triangle
What are the four types of triangles by angle measurement ?A triangle is said to be equilateral if each of its three sides is the same length. In the well-known Euclidean geometry, an equilateral triangle is also equiangular, meaning that each of its three internal angles is 60 degrees and congruent with the others.
A triangle having three acute angles is known as an acute triangle. A triangle having one obtuse angle and two acute angles is known as an obtuse triangle. No Euclidean triangle may contain more than one obtuse angle because in Euclidean geometry, a triangle's angles must add up to 180°.
A right triangle, also known as a right-angled triangle, right-perpendicular triangle, orthogonal triangle, or previously rectangled triangle, is a triangle with one right angle, or two perpendicular sides. The foundation of trigonometry is the relationship between the sides and various angles of the right triangle.
Obtuse-angled triangles or obtuse triangles are triangles with any one of its angles being an obtuse angle or more than 90°. Only 180° is equivalent to the internal angles of an acute triangle.

Low tide, represented by the integer -1, is 1 foot below the average
water level. High tide is 5 feet higher than low tide.
a. What does 0 represent in this situation?
b. Write an integer that represents the average water level relative to high tide
Answer: a. In this situation, 0 likely represents sea level or the baseline from which water levels are measured.
b. To find the average water level relative to high tide, you need to take the average of high tide and low tide.
Since high tide is 5 feet higher than low tide, you can assume that low tide is 0 ft. Therefore, the high tide is 5 ft.
The average of two values is the sum of the values divided by the number of values. So average of 0ft and 5ft is (0+5)ft / 2 = 2.5 ft.
Therefore, an integer that represents the average water level relative to high tide would be 2.5 ft.
It's worth noting that relative to high tide means how much the average water level varies (higher or lower) from the high tide, so the answer was not an integer in this case.

9. David makes $2 730.00/month. Calculate his monthly CPP and El contributions.
Hint: Find his annual gross pay first.
David's annual gross pay is $2 730.00 * 12 = $32 760.00.
What is the calculation for Davids monthly CPP and EI contribution?The current rate for Canada Pension Plan (CPP) contribution as of 2021 is 5.45% on the first $61 700 of pensionable earnings, and David's contribution would be 5.45% * $32 760 = $1 794.14.The current rate for Employment Insurance (EI) contribution as of 2021 is 1.62% on the first $54 000 of insurable earnings, and David's contribution would be 1.62% * $32 760 = $529.97.So, David's monthly CPP contribution would be $1 794.14 / 12 = $149.51, and his monthly EI contribution would be $529.97 / 12 = $44.17.To learn more about CPP refer:

The table gives a partial set of values of a polynomial h(x), which has a leading coefficient of 1.
x –2 0 1 2 3
h(x) 0 –12 0 8 0
If every x-intercept of h(x) is shown in the table and has a multiplicity of one, what is the equation of the polynomial function?
h(x) = x3 – 2x2 – 5x + 6
h(x) = x3 – 6x2 + 11x – 6
h(x) = x3 + 2x2 – 5x – 6
h(x) = x4 + 14x3 + 19x2 – 66x – 72
The equation of the polynomial function is (a) h(x) = x^3 - 2x^2 - 5x - 6
How to determine the equation of the polynomial function?From the question, we have the following parameters that can be used in our computation:
x –2 0 1 2 3
h(x) 0 –12 0 8 0
The x-intercepts are where y = 0
So, we have
x = -2, x = 1 and x = 3
The multiplicity is 1
So, we have
h(x) = (x + 2)(x - 1)(x - 3)
Expand
= (x + 2)(x^2 - 4x + 3)
This gives
= x(x^2 - 4x + 3) + 2(x^2 - 4x + 3)
So, we have
= x^3 - 4x^2 + 3x + 2x^2 - 8x + 6
Evaluate the like terms
= x^3 - 2x^2 - 5x - 6
So the equation is h(x) = x^3 - 2x^2 - 5x - 6

My water bottle was fully filled then I drank 40% of it. In this situation "y" is the amount of water remaining and " x" is the amount of water that I had at the start. Mark all the equations that represent the situation
Step-by-step explanation:
1.y = x * (1-0.4)
2.y = x - 0.4x
3.x = y / (1-0.4)
4.x = y + 0.4y
The equation 1 and 2 correctly represent the situation. In the first equation, we are multiplying the initial amount of water (x) with (1-0.4) which is the percentage of the water that is remaining after drinking 40% of it. In the second equation, we are subtracting 0.4x from x, which is equivalent to multiplying x by (1-0.4).
The equation 3 and 4 are not correct, as they are trying to calculate the initial amount of water from the remaining amount, but it's not possible to know the initial amount once it has been consumed.
You have 0.6X amount water remaining.
The amount of water remaining in the water bottle is X minus 40%. This means that if you had X amount of water at start you now have 60% of X left. That is, you have 0.6X amount of water remaining.
