Significant figures are the digits that carry meaning to its measurement. Significant figures includes all the numbers excluding all the leading zeros, trailing zeros. All non zero digits are significant. Zeros between the non zero digits are significant. In a decimal number, trailing zeros are significant.
Now, consider the given number 0.23350
Since, in a decimal number all the trailing zeros are significant.
So, in the number 0.23350 there are five significant figures 2,3,4,5 and 0.
Therefore, there are 5 significant figures in the given number.
No frickin problem my guy
x = 37.5 (or) 
Solution:
Given 
AC = 50, DE = 30, EC = 25, BE = x, BC = 25 + x
To find the value of x:
Property of similar triangles:
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.
Do cross multiplication, we get
Subtract 30x from both sides of the equation.
Divide by 20 on both sides of the equation, we get
x = 37.5 (or)
Hence the value of x is 37.5 or .
Answer:11.9 inches
Step-by-step explanation:
Circumference(c)=75inches
Pi=3.14
Circumference(c)=2 x π x radius(r)
75=2 x 3.14 x r
75=6.28 x r
Divide both sides by 6.28
75 ➗ 6.28=(6.28 x r) ➗ 6.28
11.9=r
Therefore radius=11.9 inches
