Answer:
6.98%
Explanation:
% error= |experimental value - actual value|/actual value × 100
Experimental value= 4.6 cm
Actual value= 4.3 cm
% error = |4.6-4.3|/4.3 × 100
% error = 6.98%
Answer:
x = 5 kg
Explanation:
Given data:
Number of bushel = 0.20
Mass of 0.20 bushel apples = 2 kg
Mass of 0.50 bushel apples = ?
Solution:
The given problem will solve by cross multiplication.
0.20/ 2.0 = 0.50 / x
x = 2/0.20 × 0.50
x = 10 × 0.50
x = 5 kg
