Question
Which layer of the earth's atmosphere contains the ozone
layer?Solution
About 90% of the ozone in the Earth’s atmosphere is found in the region called the Stratosphere. This is the atmospheric layer between 16 and 48 kilometers (10 and 30 miles) above the Earth’s surface.
Given a triangle with two sides measuring 12 cm and 16 cm, which of the following cannot be a possible length for the third side?
- Find the remainder on dividing (5x 3  + 4x 2  – 10x + 1) by (2x – 4).
The area (in sq, units) of the triangle formed by the graphs of 8x + 3y = 24, 2x+8 = y and the x – axis is:
If x −y =4and xy =45,thenthevalueof x 3 −y3is:
If x + y = 2 and 1/x + 1/y = 18/15, then find the value of (x3 + y3)?
22% of ‘x’ is equal to 66% of ‘y’, then find the value of x: y.
If y + 1/y = 2 then find y117 + 1/(y117)
if a2 + b2 + c2Â =Â 2(4a -5b -9c)-122 , then a-b-c = ?
If a – b – c = 0, then the value of (a2 + b2 + c2)/(b + ac) is:
If 5x - 13xy + 6y = 0, find x : y.
