Answer:
All non zero digits count in significant digits.
(a) is correct option.
Step-by-step explanation:
Given that,
1.4 has 2 significant digits.
We know that,
Significant digits :
All non zero digits count in significant digits.
All zero which is present in between two significant digits it is also significant.
Leading zero is not count as significant.
Trailing zero is count as significant.
We need to find 1.4 has 2 significant digits as a result of which rule
Using given rules
1.4 has 2 significant digits it is follows the rule of all non zero digits count in significant digits.
Hence, All non zero digits count in significant digits.
(a) is correct option.
Answer:
Ratio of circumferences: 
Ratio of radii:
Ratio of areas: 
Step-by-step explanation:
Hi there!
We are given:
- The circumference of Circle K is 
- The circumference of Circle L is 
Therefore, the ratio of their circumferences would be:
⇒ when simplified
The formula for circumference is 
, where <em>r</em> is the radius. To find the ratio of the circles' radii, we must identify their radii through their given circumferences.
If the circumference of Circle K is , or 
, then its radius is 
.
If the circumference of Circle L is , then its radius is 
, which is 2.
Therefore the ratio their radii would be:
⇒ 
⇒ when simplified
The formula for area is:
First, let's find the area of Circle K:
Now, let's find the area of Circle L:
Therefore, the ratio of their areas would be:
⇒ 
⇒ 
⇒ when simplified
I hope this helps!
Volume of the orange juice in the carton = 10*6*8 = 480 cm^3
when its turned on its side we have the equation 6*20*h = 480 where h = required height
h = 480 / (6*20) = 480 / 120 = 4 cms
answer = 4 cm
2)
The area of the whole polygon can be found by adding the area of the top square and the bottom rectangle.
Area of square = 1² = 1
Area of rectangle = 3 × 4 = 12
Area of whole polygon = 1 + 12 = 13 inches²
Hope this helps :)
