Find the measure of two supplementary angles
The measure of two supplementary angles = 180°.
Then m∠A = 104° and m∠B = 76°
According to the supplementary angles m∠A + m∠B = 180°
In the given question m∠A = (3x - 7)°,
m∠B = (2x + 2)°
then (3x - 7) + (2x + 2) = 180°
3x - 7 + 2x + 2 = 180°
5x - 5 = 180°
5(x - 1) = 180°
(x - 1) = 180 ÷ 5
x - 1 = 36
x = 37°
If x = 37°, then m∠A = 3(37°) - 7
= 111 - 7
= 104°
Similarly, m∠B = 2(37°) + 2
= 74 + 2
= 76°

Calculate the percentage change.
Give your answer to 2 decimal places.
The Percentage change in the number of trees cut down is 122.819% increase
How is a percentage determined?A % is a quantity or ratio that, in mathematics, represents a portion of one hundred. It's frequently represented by the sign "%" or just "percent" or "pct." For instance, the decimal 0.35, or the fraction, represents 35%.
By dividing the value by the entire value and multiplying the result by 100, one may determine the percentage. The percentage calculation formula is (value/total value)100%.
Using ( V2 − V1 ) \ V1 × 100 = ? We get, 122.819%
As, Number of Trees in 2018 were cut down was 149Number of Trees cut down in 2022 was 332The terms relative change and relative difference are used to compare two values while taking into account the "sizes" of the entities being compared in any quantitative research.

Find m/ABD please and thank you
∠ABD will be 40 degrees in the provided question.
Describe an angle.When two rays or straight lines intersect at one of their ends, an angle is created. Vertex of an angle refers to the point at which two points meet. The Latin word "angulus," which means "corner," is the origin of the English term "angle."
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Two rays can form angles in the plane where they are positioned. Angles are also produced when two planes intersect. These are referred to as dihedral angles.
In the given question,
As ∠ABC given = 85°
∠ABC= ∠ABD + ∠DBC
85° = 3x + 1 + 4x -7
85° = 7x - 6

what answer best describes snow metamorphosis? group of answer choices the change from snow to slush at the end of the winter seasons the process of making turning white snow into blue snow the change from snow to glacial till as the ice ages ended the change from fresh snow to firn and then to glacial ice
The correct answer is option D: the change from fresh snow to firn and then to glacial ice
The change from fresh snow to firn and then to glacial ice best describes the snow metamorphosis.
The transformation of the snow crystals gradually over time is called snow metamorphosis.
From the moment the snow crystals fall on mountains or the earth's surface they begin to metamorphose i.e. the process of ice formation.
When the granules of fresh snow called firn fall over the old snowpacks, the shape, size, and form of the snow crystals keep changing over time, and eventually, firn transforms into solid glacier ice within a period of one year.
On the contrary, glaciers take millions of years to form.

Since Jack hall is studying the effects of global warming. the effect that ice core samples tell about global warming is that Ice cores offer immediate information on past changes in greenhouse gas concentrations as well as direct proof that the climate can shift suddenly in certain situations.
What do ice core samples in Antarctica reveal about global warming?As tree rings are to trees, so are ice cores to ice sheets. Ice cores reveal information about ice sheets in a same way that tree rings do for trees. Jack was collecting ice core samples from Antarctica so that scientists could examine the chemistry and make-up of earlier climates.
To investigate the glacial and interglacial periods, ice cores have been employed. Debris and chemicals are naturally preserved by the ice and snow.
Therefore, Note that Climate scientists examine greenhouse gas concentrations in ice core layers to reconstruct historical climates. Scientists can compute how current carbon dioxide and methane concentrations compare to historical ones.

Why does the water move into the egg
Answer:
In one day the shell will be gone and water will begin moving into the egg. Osmosis is the movement of water through a semi-permeable membrane from an área higher water concentration (the vinegar) to an área of lower water concentration (the egg).
Answer: You know how when a bird is in an egg it must breathe somehow right? Well, there are very small, microscopic holes in the egg allowing air to travel inside so that the chick doesn't die. When you boil an egg, you would normally see that little bubbles emerge from the egg, this is another example of why water moves into an egg.

As atmospheric temperature rises, more arctic sea ice melts. The sea-ice reduction in turn decreases the surface albedo and causes the temperature to rise even more. This scenerio is an example of?.
Snow and ice cover less of the Earth's surface as a result of melting due to an increase in global temperature, which also lowers albedo. More energy is absorbed due to the decrease in albedo, which leads to increased warmth and melting.
Global temperature is significantly influenced by the equilibrium between the amount of solar energy reflected and absorbed by the Earth's surface. Snow, ice, and water on Earth have different capacities to reflect and absorb solar energy, and melting polar ice triggers a positive feedback loop that hastens global warming.
Pollution, including soot, decreases the albedo of ice and speeds up melting.

How does a change in the solar constant impact the absorption of shortwave radiation and the emission of longwave radiation by the earth-atmosphere system?.
The Earth-Atmosphere system will emit more longwave radiation as a result of a higher solar constant because it will absorb less solar radiation.
Any object with a temperature emits electromagnetic radiation (light). Longwave radiation has a lower energy content while shortwave radiation has a higher energy content. Because the sun is very hot and has a lot of energy to give off, it emits shortwave radiation. However, because Earth is far cooler than the sun but still emits radiation, it does so in the form of longwave radiation. Hence, a change in solar constant causes the earth to emit long wave radiation instead of shortwave radiation.

A scientist detecting d channels or gullies on the surface of mars, and deduced that there may have been water there shows inductive inference.
What is inductive inference?Inductive inference is based on a generalization from a limited set of previous observations, extending the observed pattern or relationship to other future instances or instances occurring elsewhere. Inductive inference begins with propositions about data and ends with propositions about things other than data.
Many scientists believe that liquid water once flowed through the gullies and channels visible on Mars' surface. By comparing them to similar features on Earth, it is assumed that these were formed in part by water erosion. Some of these channels are quite large, reaching lengths of 2,000 kilometers and widths of 100 kilometres.

charcoal from a hearth site in colorado, 2,000 miles south of alaska, is known to be 11,200 years old. researchers reasoned that, since glaciers prevented human migration south from the alaska-siberia land bridge between 18,000 and 11,000 years ago, humans must have come to the americas more than 18,000 years ago.
The majority of scientists agree that a single wave of people arrived in Alaska from Siberia around 13,000 years ago across a long-gone land bridge.
What became of the land link connecting Siberia and Alaska?
At its greatest length, the land bridge was nearly 1,000 miles long from north to south. When the glaciers melted at the end of the Ice Age due to climate change, Beringia was flooded approximately 10,000–11,000 years ago, severing the land bridge. By 6,000 years ago, coastlines were roughly where they are now.
When did the geographical connection between Alaska and Siberia vanish?

The hypotenuse of a right triangle measures 18 cm and one of its legs measures 7closed
Answer:
The other leg is 16.6 cm (approximately)
Explanation:
We have a right triangle, with the hypotenuse = 18, one side = 7, and the other side = x.
Since this is a right triangle, we will use the Pythagorean Theorem to find the value for x.
So, let a = 7 for one side, and let c = 18 for the hypotenuse. And, let c = x for the other side.
The Pythagorean Theorem is:
c^2 = a^2 + b^2.
So, 18^2 = 7^2 + x^2
324 = 49 +x^2
And, x^2 = 324 - 49 = 275
So, x = sqrt(275) = 16.58 cm (approximately).
Conclusion: The other leg is 16.6 cm (approximately).
