Two carpenters are building a fence after 5 minutes,one carpenter is finished 4/7 of the way an the other is finished 1/8 of the

torisob [31]

The first carpenter is 0.4464 of the way is ahead of the second carpenter

<u>Solution:</u>

Given, Two carpenters are building a fence

After 5 minutes, one carpenter is finished 4/7 of the way

Second carpenter finished 1/8 of the way

Now, let us find the work done by each carpenter

$\begin{array}{l}{\text { For } 1^{\text {st }} \text { carpenter }=\frac{4}{7}=0.5714 \text { approximately. }} \\\\ {\text { For } 2^{\text {nd }} \text { carpenter }=\frac{1}{8}=0.125}\end{array}$

Then, extra work done by first carpenter over second carpenter = work done by first carpenter – work done by second carpenter

= 0.5714 – 0.125 = 0.4464

Hence, the 1st carpenter is 0.4464 of the way is ahead of the 2nd carpenter

What is the value of (Negative 14 Superscript 0 Baseline) Superscript negative 2? Negative StartFraction 1 Over 196 EndFraction

Nookie1986 [14]

Answer:

1

Step-by-step explanation:

Assuming, we want to find the value of $((-14)^0)^{-2}$

Recall that: any non-zero number exponent zero is 1.

Using this property, we simplify our expression to $(1)^{-2}$ since $(-14)^0=1$

Now using the property of exponents: $a^{-n}=\frac{1}{a^n}$

This implies that: $1^{-1}=\frac{1}{1^2}=\frac{1}{1}=1$

The correct answer is 1
