Answer:

Explanation:
The diagonal of a square is x units.
Let the side of a square is s.
Using pythagoras,

The area of the square is,
A = s²
So,

So, the area of a square is
sq units.
Answer: B. Metamorphic rocks
Explanation: Metamorphic rocks are those that have undergone changes due to extreme heat and pressure. Thus, the rock, from which it becomes a metamorphic rock, is heated at temperatures above 150-200 ° and exposed to a pressure of 1500 bar. In this way, the structure of the rock is changed, in terms of the arrangement of the atoms, and the result is a change of physical and chemical properties. There are two basic types of metamorphic rocks: foliated and slate. Generally, some of the metamorphic rocks are anthracite, schist, quartzite, marble, etc.
Answer:
if you live in the northern hemishpere the earth is closer to the sun during winter but the earth is tilted so we are away from the sun making it winter while the southern hemisphere is closer. and when its our summer the earth is further away but the earth is tilted to make us closer than the southern hemisphere
All the options are correct.
If we look at the formula of prismoidal, we can see that it contains, three areas = area of faces at top and bottom and area of midway section
Thus it can be used to calculate the a) calculate surface area for cylindrical rings And b) estimate the surface area of edged non-prismoidal solids.
In the volume formula of prismoidal, the factor (depth/6) is multiplied by the three areas as mentioned above, this gives the volume of faces at top and bottom and midway section. Thus option C and D are also correct.
Answer:
c. Montevideo, Uruguay (35°S)
Explanation:
Montevideo, Uruguay (35°S) had the longest day on June 21, 2019 during the Summer Solistics when the sun is directly over the tropic of cancer which is on latitude 23.5 degrees North.
