Her rate was faster in the FIRST because her rate was - 19 ft/ minutes in the FIRST PART and - 10ft/minute in the SECOND part

Step-by-step explanation:

Portion 1

Time taken to hike down = 10 minutes

Change in elevation = - 190 ft

Portion 2

Hiked down for further 20 minutes

Change in elevation = - 200ft

During which portion of the hike was her rate of change in elevation greater?

Rate of change in elevation :

Change in elevation / time

Portion 1:

Rate of change in elevation :

Change in elevation / time

- 190 ft / 10 minutes = - 19 ft/minutes

Portion 2:

Rate of change in elevation :

Change in elevation / time

- 200 ft / 20 minutes = - 10 ft/minutes

Her rate was faster in the FIRST because her rate was 19 ft/ minutes in the FIRST PART and 10ft/minute in the SECOND part

A trapezium, also known as a trapezoid in some regions, is a quadrilateral with two parallel sides and two non-parallel sides. The missing side length of the trapezium is 10 cm.

The formula for the area of a trapezium is given by:

Area = (1/2) * (a + b) * h

where a and b are the lengths of the parallel sides of the trapezium and h is the height.

In this case, we are given that the area of the trapezium is 120 cm². Let's substitute this into the formula:

120 = (1/2) * (5 + 10) * h

To simplify, we can add the lengths of the parallel sides:

120 = (1/2) * 15 * h

Next, we can simplify further by multiplying:

120 = 7.5 * h

To isolate h, we divide both sides of the equation by 7.5:

120 / 7.5 = h

This gives us the height of the trapezium. Solving the equation, we find:

h = 16

So, the height of the trapezium is 16 cm.

Now, let's substitute the given values and the height into the formula to find the missing side length:

120 = (1/2) * (5 + x) * 16

We can simplify this equation:

120 = (1/2) * (5 + x) * 16
120 = 8 * (5 + x)
120 = 40 + 8x
8x = 120 - 40
8x = 80
x = 80 / 8
x = 10

Therefore, the missing side length of the trapezium is 10 cm.

Answer:

Answer:(3, 5) where the result of the subtraction is 2 and 0, respectively.

Step-by-step explanation:

To find x - y, we need to subtract each element of y from each element of x. That is:

x - y = (3 - 1, 3 - 4, 3 - 7, 3 - 9, 5 - 1, 5 - 4, 5 - 7, 5 - 9, 7 - 1, 7 - 4, 7 - 7, 7 - 9)

Simplifying this expression, we get:

x - y = (2, -1, -4, -6, 4, 1, -2, -4, 6, 3, 0, -2)

So the answer is the set of values (3, 5) where the result of the subtraction is 2 and 0, respectively.

Step-by-step explanation:

The area of the given Circle C is; 324π

From the attached diagram, we see that;

WX is the radius of circle X and is equal to 8 units

Similarly, ZY is radius of circle Y and is equal to 10 units.

Thus, diameter of circle X = 8 * 2 = 16 units

Diameter of circle Y = 10 * 2 = 20 units

Using the Pythagorean Theorem, it is found that the side length is of x = 6.93.

The Pythagorean Theorem relates the length of the legs \(l_1\) and \(l_2\) of a right triangle with the length of the hypotenuse h, according to the following equation:

\(h^2 = l_1^2 + l_2^2\)

In this problem, we have that:

\(h = 13, l_1 = 11, l_2 = x\)

Hence, applying the Theorem:

\(h^2 = l_1^2 + l_2^2\)

\(13^2 = 11^2 + x^2\)

\(x^2 = 169 - 121\)

\(x = \sqrt{48}\)

x = 6.93.

The concentration of hydrogen ions in a liter of the sports drink is approximately 3.98 x 10^(-3) moles per liter.

The pH of a substance is a measure of its acidity or basicity and is defined as the negative logarithm (base 10) of the hydrogen ion concentration [H+]. The formula for pH is given as pH = -log[H+].

To find the concentration of hydrogen ions in a liter of a sports drink that has a pH of 2.4, we can use the formula pH = -log[H+]. Rearranging this formula, we get [H+] = 10^(-pH).

Substituting the given value of pH into this expression, we get [H+] = 10^(-2.4).

It's worth noting that the hydrogen ion concentration is related to the acidity of a solution; the higher the hydrogen ion concentration, the more acidic the solution. The pH scale ranges from 0 (most acidic) to 14 (most basic), with a pH of 7 being neutral. The sports drink in question has a relatively low pH, indicating that it is quite acidic.

In the realm of geometry, lines and points are foundational, undefined terms. The postulate asserting the existence of exactly one line between any two points is best represented by option (c), where a straight line passes through points A and B, affirming the fundamental concept that two points uniquely determine a line.

The correct answer is option C.

In geometry, the foundational concepts of lines and points are considered undefined terms because they are fundamental and do not require further explanation or definition. These terms serve as the building blocks for developing geometric principles and theorems.

One crucial postulate in geometry states that "Exactly one line exists between any two points." This postulate essentially means that when you have two distinct points, there is one and only one line that can be drawn through those points.

To illustrate this postulate, we can examine the given options. The diagram that best represents this postulate is option (c), where there is a straight line passing through points A and B. This choice aligns with the postulate's assertion that a single line must exist between any two points.

Therefore, among the provided options, only option (c) accurately depicts the postulate. It visually reinforces the idea that when you have two distinct points, they uniquely determine a single straight line passing through them.

The volume of the water in the fish tank is 135.27 cubic meters if the top 1/3 of the tank is just air.

To find the volume of the fish tank containing water, we need to find the volume of the fish tank and then subtract the volume that is occupied by the air i.e 1/3 of the volume of the tank.

So, the volume of the fish tank is :

=length x width x depth of the tank

=10.2 meters x 5.8 meters x 3.5 meters

= 203.94 cubic meters

Now we need to find the volume of the air that is occupied by the fish tank which is :

=1/3x the volume of the fish tank

=1/3x203.94 cubic meters

=68.67 cubic meters

The volume of the fish tank containing just water is:

=volume of the fish tank - the volume of the air occupied
