The base area of a rectangular tank is 300 cm square. The capacity of the tank is 6 litres. Peter fills the tank with water up to 4/5 of its height. What is the height of the water leve?

a) Relationship between corresponding sides: the corresponding sides are parallel and have a ratio of k in length.

b) Relationship between corresponding sides' orientations: The corresponding sides will still be parallel to the original sides.

c) Relationship between corresponding angles:the corresponding angles are congruent.

What do you mean by congruent angles?

Congruent angles are angles that have the same measure or size. In other words, if two angles have the same number of degrees or radians, they are said to be congruent. When we say that two angles are congruent, it means that they are exactly the same shape and size, and they can be superimposed on each other without any rotation or scaling. Congruent angles play an important role in geometry, as they allow us to prove that two figures are similar or congruent.

To apply a dilation with scale factor k centered at the origin, we multiply the coordinates of each vertex by k. So, to find the coordinates of A', B', and C', we will multiply the coordinates of A, B, and C by the scale factor.

a) The relationship between corresponding sides in terms of their lengths:

Let's denote the scale factor by k. The distance between two points (x1, y1) and (x2, y2) is given by the distance formula, which is:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

When we multiply each coordinate by k, the distance between the two points is multiplied by k as well. So, if AB has length dAB and A'B' has length dA'B', we have:

dA'B' = k * dAB

Similarly, we can find the relationship between the lengths of BC and B'C', as well as between the lengths of AC and A'C'.

b) The relationship between corresponding sides in terms of their orientations:

The orientation of a line is given by its slope. If two lines have the same slope, they are parallel or collinear. If they have slopes that are negative reciprocals of each other, they are perpendicular. When we multiply the coordinates of a point by k, the slope of any line passing through that point is multiplied by k as well. So, if the slope of AB is mAB and the slope of A'B' is mA'B', we have:

mA'B' = k * mAB

We can use this to find the relationship between the slopes of BC and B'C', as well as between the slopes of AC and A'C'.

c) The relationship between corresponding angles in terms of their measures:

The measure of an angle is determined by the slope of the line that contains the angle. When we multiply the coordinates of a point by k, the slope of any line passing through that point is multiplied by k as well. This means that the measure of any angle that includes the origin is unchanged by the dilation. However, the measure of any angle that does not include the origin is multiplied by a factor of k. So, if angle ABC has measure x and angle A'B'C' has measure y, we have:

y = k * x

We can use this to find the relationship between the measures of angles BAC and B'A'C', as well as between the measures of angles CBA and C'B'A'.

Answer:

R2689 IS THE CORRECT ANSWER

Mrs. Flips sold 240 large chocolate chips.

Mrs. Flips sold 60 small peanut butter cookies.

In order to write the required expressions that models the situation, we would assign variables to the number of large chocolate chips and the number of small peanut butter cookies, and then translate the word problem into algebraic equation as follows:

Since Mrs. Flips charged $1 for the chocolate chip and 50-cents for the peanut butter cookies and collected $270 total, an expression that models the situation is given by:

x + 0.5y = 270

Additionally, she sold a total of 300 cookies:

x + y = 300

270 - 0.5y + y = 300

0.5y = 30

y = 60 small peanut butter cookies.

x = 270 - 0.5(60)

x = 240 large chocolate chips.

The cross section is shaped like a circle.

A cone is a three-dimensional geometric object with a flat base and a smooth transition to the apex or vertex.

If a cone is sliced such that the cross section is perpendicular to its base and intersects its vertex, the cross section will be a circular shape. This is because the cross section cuts through the entire cone at a right angle, producing a circle that is defined by the curved surface of the cone and the slicing plane. The diameter of the circle is equal to the base diameter of the cone, and its center is located at the midpoint of the base.

Assuming a Poisson distribution, on the average, 6 cars arrive at the drive-up window of a bank every hour, the probability that no more than 5 cars will arrive in the next half-hour is 0.75.

The Poisson distribution can be used to model the number of events that occur in a fixed interval of time. In this case, the average number of cars arriving at the drive-up window of a bank is 6 cars per hour, so we can use the Poisson distribution to calculate the probability of a certain number of cars arriving in a half-hour interval.

To calculate the probability that no more than 5 cars will arrive in the next half-hour, we can use the cumulative Poisson distribution function, which gives the probability that the number of events is less than or equal to a given value.

The cumulative Poisson distribution function can be calculated using the following formula:

P(X <= x) = Σ P(X = i) for i = 0, 1, 2, ..., x

Where X is the number of cars arriving in a half-hour interval, and x is the given value (in this case, x = 5).

The mean number of cars arriving in a half-hour interval is 3 (6 cars per hour / 2), so the cumulative Poisson distribution function can be calculated as follows:

P(X <= 5) = Σ P(X = i) for i = 0, 1, 2, 3, 4, 5

= P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5)

= (e^-3) * (3^0) / 0! + (e^-3) * (3^1) / 1! + (e^-3) * (3^2) / 2! + (e^-3) * (3^3) / 3! + (e^-3) * (3^4) / 4! + (e^-3) * (3^5) / 5!

= 0.0498 + 0.1494 + 0.224 + 0.224 + 0.1494 + 0.0498

= 0.75

Therefore, the probability that no more than 5 cars will arrive in the next half-hour is approximately 0.75, or 75%.

From the given table it is noticed that the line passing through the points (2,5), (4,10), (6,15) and (8,20).

The slope of the line is

The slope of line is . It means the value of y increased by 5 if the value of x increased by 2.

From the given points we can noticed that the value of y increased by 5 if the value of x increased by 2. So, the function has same slope for any two points.

Since the rate of change (slope) is same for all points, therefore the table represents a linear function.

If we plot these points on a coordinate plane and connect then we get a straight line. I means it is a  linear function.

The same curves can be defined by a number of seemingly unrelated mathematical definitions, which all correspond to it.

A line and a point (the focus) are two components of one definition of a parabola (the directrix).

The directrix is not the main focus.

The locus of points in that plane that are equally spaced apart from the directrix and the focus is known as the parabola.
