Question
In a computer catalogue, a computer monitor is listed as being 27 cm. This distance is the diagonal distance across the screen. If the screen measures 15 cm in height, what is the actual width of the screen to the nearest inch?
Hint:
Pythagoras' theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
If a is the perpendicular, b is the base, and c is the hypotenuse, then according to the definition, the Pythagoras Theorem formula is given as
c2= a2 + b2
The correct answer is: the width of the screen is 9 inches.
Here, Length of height(h) = 15 cm
Length of hypotenuse(d) = 27 cm
Let’s say that the width of the screen is b
Using Pythagoras theorem
d2 = h2 + b2
272 = 152 + b2
b2 = 272 - 152
d = 
= 22.45 cm 
9 inch
Final Answer:
Hence, the width of the screen is 9 inches.
= 22.45 cm 9 inchFinal Answer:
Hence, the width of the screen is 9 inches.

Which of the following Compound inequalities have the solution x < 3, select all that apply.
You can also follow these steps to solve the compound inequality with the equation for example: 3x + 5 < 6:
Subtract 5 from both sides.
3x + 5 - 5 < 6 - 5
Simplify and subtract the numbers.
And we get, 3 x < 1
Divide both sides by the same factor.
3x/3 < 1/3
Cancel terms that are in both the numerator and denominator.
and the solution is x < 1/3.

When two simple inequalities are combined, the result is a compound inequality. For example, a sentence with two inequality statements connected by the words "or" or "and" is a compound inequality. The conjunction "and" denotes the simultaneous truth of both statements in the compound sentence. So it is when the solution sets for the various statements cross over or intersect. E.g., for "AND": Solve the statement where x: 3 x + 2 < 14 and 2 x – 5 > –11. The solution set is
{ x| x > –3 and x < 4}. All the numbers present to the left of 4 are denoted by x < 4, and the numbers to the right of -3 are represented by x > -3. The intersection of these two graphs is comprised of all integers between -3 and 4.
