Leo estimates that a package weighs 27 pounds. The postal clerk weighs it and finds it weighs 20 pounds. What is the percent err

Eva8 [605]

Answer: 35%

Step-by-step explanation:

Given

Weight measured by Leo $W_1=27\ pounds$

Weight measured by the clerk $W_2=20\ pounds$

Percentage error is

$\Rightarrow \%\ \text{error}=\dfrac{\text{False value}-\text{Correct value}}{\text{Correct value}}\times 100$

Putting values

$\Rightarrow \%\ \text{error}=\dfrac{27-20}{20}\times 100=35\%$

Whats the maxium volume that hold 1 2/3 inches and length of 2 1/3 and width of 2 inches

Molodets [167]

so a box will be a rectangular prism, and thus its volume will simply be the product of its length, width and height.

let's firstly convert the mixed fractions to improper fractions and the multiply.

$\bf \stackrel{mixed}{1\frac{2}{3}}\implies \cfrac{1\cdot 3+2}{3}\implies \stackrel{improper}{\cfrac{5}{3}}~\hfill \stackrel{mixed}{2\frac{1}{3}}\implies \cfrac{2\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{7}{3}} \\\\[-0.35em] ~\dotfill\\\\ \textit{volume of a rectangular prism}\\\\ V=Lwh~~ \begin{cases} L=\frac{7}{3}\\ w=2\\ h=\frac{5}{3} \end{cases}\implies V=\cfrac{7}{3}\cdot 2\cdot \cfrac{5}{3}\implies V=\cfrac{70}{9}\implies V=7\frac{7}{9}$
