Answer:
B = 900 Libros
A = 2700 Libros
C = 1800 Libros
Step-by-step explanation:
A = 3B
2B = C
A + B + C = 5400
3B + B + 2B = 5400
6B = 5400
B = 5400 / 6
B = 900 Libros
A = 3B
A = 3(900)
A = 2700 Libros
C = 2B
C = 2(900)
C = 1800 Libros
Answer:
(a) 36.36%
(b) 0.36%
(c) 0.06%
Step-by-step explanation:
Given that the time intervals measured with a stopwatch have an uncertainty of about 0.2 s.
We want to know what is the percent uncertainty of a hand-timed measurement of:
(a) 5.5 s
Percentage = (0.2/5.5) × 100
≈ 36.36%
(b) 55 s
Percentage = (0.2/55)×100
≈ 0.36%
(c) 5.5 min
5.5 min = 5.5 × 60 s
= 330 s
Percentage = (0.2/330)×100
≈ 0.06%
<h3>Explanation:</h3>
We have to find the area of the square shaped room.
<h3>Given:</h3>
Side of the square shaped room = 10 m
The cost of flooring a square metre is Rs. 50
<h3>To Find:</h3>
The cost of flooring a square shaped room.
<h3>Formula:</h3>
Area of square = Side × Side
<h3>Solution:</h3>
Area of the square = 10 × 10 = 100 sq.m
1 sq.m = Rs. 50
100 sq.m = 50(100) = Rs. 5,000
<h2>Answer:</h2>
The cost of flooring a square shaped room of side 10 m is <u>Rs. 5,000</u><u>.</u>
