Complete Question
You are organizing books on a shelf. Each book has a width of 3/4 inch. The number of shelves is 12.
Write and solve an inequality for the numbers of books b that can fit on the shelf.
Answer:
a) Inequality for the numbers of books b that can fit on the shelf
= b ≤ 3x/4
b) The numbers of books b that can fit on the shelf is b ≤ 9 books
Step-by-step explanation:
Let the number of books = b
Let us assume the number of shelves= x
Each book has a width of 3/4 inch.
Therefore,
b ≤ 3/4 × x
b ≤ 3x/4
If the number of the shelves is 12
Therefore, the number of books bis
b ≤ 3 × 12/4
b ≤ 9 books

Answer: B. 5root(3)
Use Pythagorean’s theorem to solve this problem. We know one side and the hypotenuse, so we can solve for the other side.
a² + b²= c²
5² + b² = 10² (plug in 5 for one side, and 10 for the hypotenuse)
25 + b² = 100 (square 5 and 25)
b² = 75 (subtract 75 from both sides)
b=√(75) (take the square root of both sides)
b=√(25*3) (factor out a square)
b=5√(3) (simplify radical)

Answer:
- length: 4 m
- breadth: 3 m
- height: 1 m
Step-by-step explanation:
The product of ratio units is 12 unit³, so each must stand for 1 m.
The dimensions of the room match the ratio units:
4 m length by 3 m breadth by 1 m height
Answer:
Yes the probability of getting at least one airplane from two boxes is 3/4 which is greater than 0.5.
Step-by-step explanation:
The probability of getting at least one aeroplane is calculated by = 1 -(P(not aeroplane from 1st box) P (not aeroplane from 2nd box))
P(at least one aeroplane)= 1- {P(not aeroplane)P(not aeroplane)}
Suppose there is one helicopter and one aeroplane in each box so
P(at least one aeroplane)= 1- {(1/2) (1/2))}
P(at least one aeroplane)= 1- 1/4
P(at least one aeroplane)= 3/4 > 0.5
So the probability of getting at least one airplane from two boxes is 3/4 which is greater than 0.5
