This sounds like you're asking about a binary floating
point format, though I'm not positive because of the 
vocabulary you use. I interpret "characteristic" to mean 
"exponent" and "significand" as "fraction" (or "mantissa"). 

If that's true, then you've described: 

sign(1) + binary fraction(20) + binary exponent(10) 

Note that there are other possible interpretations (for 
example, a base-16 exponent). 

Since I'm assuming a binary exponent, we can use the same 
trick that IEEE 754 floating point standard does, and assume 
an "implicit" leading "1" to the fraction portion. This 
trick means that the fractional part will be between 
the following numbers (in base 2): 

1.00000000000000000000 (1 followed by twenty zeros)

How can you use a number line to compare and order numbers?

miskamm [114]

The numbers going to the left on a number line means the values are smaller and the numbers going to the right means the values are bigger.

Take the value '0' for example, the value on the right of zero is '1', which is a value bigger than zero, and the value to the left of '0' is '-1', which is a value smaller than zero.

PROVE THESE TRIANGLES ARE CONGRUENT

jenyasd209 [6]

Answer:

These triangles cannot be proved congruent

Step-by-step explanation:

The theorems for congruence are SSS SAS ASA AAS. Here, there is only one common side and one common angle marked, therefore you cannot prove congruency.

Does the following infinite series converge or diverge? 1/3+2/9+4/27+8/81

Norma-Jean [14]

Answer:

converge

Step-by-step explanation:

The ratio that you multiply by to get the next term is 2/3, which is less than 1, so the geometric series converges by the Geometric Series Test.
