Hilary Unraveled 3.0 centimeters of ribbon then continued to unravel 1.5 more centimeters. Which horizontal number line could be

Snezhnost [94]

Answer:

The horizontal number line that could be used to show number of centimeters of ribbon Hilary unraveled is 3cm to 4.5cm

Explanation:

Given that Hilary has already unraveled 3.0 centimeters of ribbon and then continues to unravel 1.5 more.

So starting will be 3.0 cm and maximum ribbon unravelled will be equal to 4.5cm so the horizontal number line that could be used would be from 3cm to 4.5cm including both fractional and integral values.

Answer:

ab+bc+ca=0

Step-by-step explanation:

We are given:

$x^a=y^b=z^c$

xyz=1

Separating equations:

$x^a=z^c$

$y^b=z^c$

Solving the first equation for x:

$\displaystyle x=z^\frac{c}{a}$

Solving the second equation for y:

$\displaystyle y=z^\frac{c}{b}$

Substituting in

xyz=1:

$\displaystyle z^\frac{c}{a}z^\frac{c}{b}z=1$

Adding the exponents:

$\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=1$

Since $1=z^0$ :

$\displaystyle z^{\frac{c}{a}+\frac{c}{b}+1}=z^0$

The base is z on both sides so we get rid of them:

$\displaystyle \frac{c}{a}+\frac{c}{b}+1=0$

Multiplying by ab:

bc+ac+ab=0

Reordering:

ab+bc+ca=0
