The rules of the calculation are:
- Round the result to the same number of significant figures as the value with the least number of significant figures
- Round up if the digit to be dropped is 5 or greater.
<h3>How to determine the rule?</h3>

The equation is given as:
0.738 × 0.28 = 0.20664
When approximated, we have:
0.738 × 0.28 ≈ 0.21
The above approximation can mean any of the following:
- To 2 decimal places
- To the nearest hundredth
- To 2 significant digits

<u><em>Answer: y=27 and 27=y *The answer should be positive sign.*</em></u>
Step-by-step explanation:
multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.
a*c=b*c
division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.
a/c=b/c for c≠0
multiply by 3 both sides of an equation.
3*2/3y=18*3
simplify.
18*3=54
2y=54
divide by 2 both sides of an equation.
2y/2=54/2
simplify by equation.
54/2=27
27*2=54
54/27=2
2*27=54
y=27
Hope this helps!
Thanks!
Have a great day!
Answer:
The midpoint of the horizontal line segment (-6, 3) (10, 3) is (2, 3)
Step-by-step explanation:
The midpoint formula: (x1+x2)/2 , (y1+y2)/2
(-6+10)/2 , (3+3)/2
4/2 , 6/2
2, 3
Answer – 7 years old
SOLVINGS
Let Kevin’s present age be ‘x’
In 56 years, Kevin’s age will be x + 56
In 56 years, Kevin’s age will be 9x
Therefore, x + 56 = 9x
Solving for x
x + 56 = 9x
9x – x = 56
8x = 56
x = 56/8
x = 7
