When the coloured water evaporates and condenses on the inside of the top cup, there is no colour in the water on the inside surface of the cup.
As water molecules in the air cool, they slow down and combine into tiny droplets of liquid water. This process is called condensation. This happens when water molecules in the air touch the outside of a cold mug exposed to air.
Water vapour in the air is extracted by several techniques, such as cooling the air below the dew point, exposing the air to a desiccant, using membranes that allow only water vapour to pass, collecting the mist, or pressurizing the air. I can do it.
Common examples are water forming on the outside of a cold mug, or moisture forming on a car window on a cool night.

What is trigonometric ratios?Trigonometric functions are real functions in mathematics that connect an angle of a right-angled triangle to ratios of two side lengths. They are widely utilized in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many more. The values of all trigonometric functions depending on the ratio of sides of a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of a right-angled triangle with respect to that acute angle.
Here,
cos 30°=b/15
b=15*cos 30°
b=13 units
since this is square so all sides are equal.

Pete has 3 puppies. The puppies' names are Jack, Buster, and Coco. Pete's three puppies share 1 whole bone. Jack ate 2/16 of the bone Buster ate 5/8 of the bone. What fraction of the bone did Coco eat?
Answer: 2/8
Step-by-step explanation: 2/16 can be simplified to 1/8, 1/8 + 5/8 = 6/8, since a whole bone is 8/8, or 1. 8/8 - 6/8 = 2/8

What do you think about proportionality?We must determine the ratio of the two quantities for each value supplied in order to determine if two quantities are proportionate. The proportionate link between them is evident if their proportions are equal. Their connection is not proportionate if all the ratios are out of balance.
What is proportionality?When two quantities or variables are linearly related in mathematics, the term "proportional" is used. Both quantities increase by two times when one increases by two. Each variable decreases in proportion to the other when it falls to 1/100th of its previous value.

A person standing close to the edge on top of a 96-foot building throws a ball vertically upward. The quadratic function h(t) = - 16t^2 + 116t + 96 models the balls height about the ground, h(t), in feet, t seconds after it was thrown.
a) What is the maximum height of the ball? __ feet
b) How many seconds does it take until the ball hits the ground? __ seconds
Answer:
the answer is 306.25 feet and b is 8 sec
Step-by-step explanation:
Explanation
The height of the ball as a function of the time is given by the following formula:
A. Maximum height of the ball
To find the value of the maximum height, we maximum the function h(t) computing its first derivative and equalling the result to zero:
Solving the last equation for t, we get time t when the height is maximum:
So the maximum height is given by the value of h(t) when t = 2.5:
The maximum height is 196ft.
B. Time until the ball hits the ground
The ball will hit the ground when h(t) = 0. So we must find the value of t such that:
Solving this equation is equivalent to finding the roots of a second-order polynomial:
Where:
• a = -16,
,
• b = 80,
,
• c = 96.
The roots of this polynomial are given by the following formula:

What’s the value of z ?
Answer:
z = 7
Step-by-step explanation:
We know that, sum of the exterior angles of a quadrilateral is added up to 360°.
Accordingly,
115 + 7z + 12z + 16z = 360
Combine like terms.
115 + 35z = 360
Subtract 115 from both sides.
35z = 360 - 115
35z = 245
Divide both sides by 35.
z = 7

What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
A triangle is a polygon that has three sides and three vertices. It is one of the basic figures in geometry.
For a regular polygon of any number of sides, therefore the sum of its exterior angle is 360°.
Given statements that the corresponding sides might be altered, they must still be proportionate.
The triangles will be congruent also, if they are.
But the angles must always line up otherwise the triangle's overall shape will change and it won't look the same.
Two comparable triangles must have proportional corresponding sides.

Water is being from a pool. The volume of water in the pool t minutes after begin draining is given by the function V(t)=4522(0.94)^t. Which of the following is the closest to the percent volume that has drained out of the pool after 10 minutes
The closest percentage volume that has drained out is 46%
How to determine the percentage volume?From the question, we have the following parameters that can be used in our computation:
V(t) = 4522(0.94)^t
The initial volume is calculated when t = 0
So, we have
V(0) = 4522(0.94)^0
Evaluate
V(0) = 4522
The new volume is calculated when t = 10
So, we have
V(10) = 4522(0.94)^10
Evaluate
V(10) = 2435.62
The percentage is then calculated as
Percentage = (V(10) - V(0))/(V(0))
So, we have
Percentage = (2435.62 - 4522)/4522
Evaluate
Percentage = -46%
Hence, the percentage is 46%

What are functions?The relationship between two sets of numbers is described mathematically by a function. It is a mathematical equation that assigns a unique output value to each input value inside a specific domain. Functions are frequently expressed by a letter, such as F(x) = 3x+ 4 or g(x), where the letter indicates the function and the input value is represented by the variable x.
Functions can be either linear or nonlinear, and they can have a single or numerous outputs for each value of the input. They are frequently employed to simulate real-world situations and generate predictions based on available information. Functions can be graphed on a coordinate plane to visualise their behavior, and they can be combined or transformed using various mathematical operations.

since:
a²-2ab+b² = (a-b)²
and
a²+2ab+b² = (a+b)²
A trinomial is written as the square of the a binomial in the equations above.
Knowing that the aforementioned equations are correct, we may use the binomial that has been provided and proceed backwards from there:

Answer: 8.8 (-8.8'F)
Step-by-step explanation:
What we know:
Temperature started as 7.2
Temperature ended as -1.6
We need to find the difference
How to solve:
By doing simple subtraction, we can solve this.
Process:
Write equation 7.2 - (-1.6) = ?
Simplify 7.2 + 1.6 = ?
Solve = 8.8
Solution: {8.8 (-8.8'F)}
The temperature decreased by 8.8'F, but it increased/changed by -8.8'F.
