Answer:
a=2.69 in
b=11.37 in
c=11.69 in
Explanation:
If we mark shorter side as a, we can write all sides expressed through a.
So:
- short side is a
- longer side is 6 in longer then twice the length of short side b = 2a + 6
- hypotenuse is 9 in longer then short leg c = a + 9
Now we can write the Pythagoras theorem a^2 + b^2 = c^2 as:
a^2 + (2a + 6)^2 = (a + 9)^2
a^2 +4a^2+24a+36 = a^2+18a+81
When we solve this, we get:
4a^2 + 6a - 45 = 0
Now we have a quadratic equation which can be solved as:
x = -b ± √(b^2 - 4ac) / 2a
When we plug in the values, we get that x equals 2.69 or -4.19
It's obvious that length of a side can not be negative, which means that a = 2.69 in.
Side b is 2a + 6, which is 11.37 and c is a + 9 which is 11.69 inches.
These are lengths rounded to two decimals so due to this approximation they may not be completely precise.
Answer:
The correct answer is A) Silt.
Explanation:
When a volcanic eruption occurs it leads to deposition. During the deposition, silt builds up in situ the volcanic site. Silt refers to small and tiny pieces of rock in a particular place.
Silty soil is very fertile, promotes water retention and circulation. It is good for growing plants.
Cheers!
Around 3,000 sea otters live in southern waters at this time. The California population is regarded as threatened because it has a constrained geographic range and lives close to habitation. Otters don't have a lot of body fat, but their fur is quite dense. This implies that they are susceptible to cold readily, particularly in water. They can transfer body heat and keep each other warm by sleeping snuggled together and holding hands. Whatever the motivation, it is undeniable that otters adore cuddling.
In the wild, they have a lifespan of eight to nine years, but in captivity, they have reached 21 years of age. River otters in North America were heavily pursued for their fur in the 19th and 20th centuries, and some regions still practice hunting today.

They can transfer body heat and keep each other warm by sleeping snuggled together and holding hands. Whatever the motivation, it is undeniable that otters adore cuddling. Despite changing climatic conditions, whales, dolphins, seals, and other marine mammals can produce their own heat and maintain a constant body temperature. They are endothermic homeotherms, also known as "warm-blooded" animals, just as humans. Fur or blubber on marine creatures provides excellent insulation as well. The sea otter possesses the densest hair of any mammal that is known to exist, with 130,000 hairs to every square centimeter of skin. Fur traps air, a good insulator, and does so most effectively when it is dry.

<u>Answer:</u>
Non conformity is the type of unconformity separating the 2 rock strata.
<u>Explanation:</u>
There are 4 types of unconformities, among which the non conformity is the type of unconformity that separates two rock types while one among them is younger and the other is older. It usually exists between young sedimentary rocks and old igneous or metamorphic rocks. The non conformity refers to the old erosional feature on the underlying rock. It also suggests that, a long term uplift has taken place.
