14. What is the value of x? Justify each step.

kap26 [50]

Answer:

x=3

Step-by-step explanation:

Given information: AC=32, AB=2x, BC=6x+8 and point B lies between A and C.

We need to find the value of x.

$AB+BC=AC$ (Segment addition property)

Substitute the given values.

$2x+6x+8=32$ (Substitution)

Combine like terms.

$8x+8=32$ (Simplification)

Subtract 8 from both sides.

$8x+8-8=32-8$ (Subtraction property of equality)

$8x=24$

Divide both sides by 8.

$x=\frac{24}{8}$ (Division property of equality)

$x=3$

Therefore, the value of x is 3.

How many digits in hex do you need to represent integers up to 1, 000?

shepuryov [24]

You can convert 1000 to hex and see how many digits that requires:

$1000_{10}=(3\cdot16^2+14\cdot16+8)_{10}=3\mathrm e8_{16}$

So every integer below 1000 needs up to 3 digits.

Alternatively, we know that $16^2=256$ , and that $16^n$ requires $n+1$ digits in its hex representation (e.g. $16_{10}=10_{16}$ ). Taking the logarithm, we get $\log_{16}16^2=2$ , and adding 1 gives the number of digits needed to represent $16^2$ . Similarly,

$\lfloor\log_{16}1000\rfloor+1=3$
