A package of paper weighs 3\frac{4}{6} ounces. If Edward put 3\frac{1}{2} packages of paper on a scale, how much would they weig

Nadusha1986 [10]

Answer:

They would weight $1\frac{1}{21}$ ounces

Step-by-step explanation:

Weight of complete package of paper = $3 \frac{4}{6}$ ounces

Weight of complete package of paper = $\frac{22}{6}$ ounces

Edward put $3\frac{1}{2}$ packages of paper on a scale

So, Weight of $3\frac{1}{2}$ packages $= \frac{\frac{22}{6}}{3\frac{1}{2}}$

Weight of $3\frac{1}{2}$ packages $= \frac{\frac{22}{6}}{\frac{7}{2}}$

Weight of $3\frac{1}{2}$ packages = $\frac{22}{21}=1\frac{1}{21}$

Hence They would weight $1\frac{1}{21}$ ounces

For some reason it says square but please help! I need to know step by step what to do.

quester [9]

Answer:

8.06 inches

Step-by-step explanation:

The diagram shows a rectangle with width of 4 inches and area of 28 square inches.

Use area formula:

$A_{\text{rectangle}}=\text{Width}\times \text{Length}$

So,

$28=4\times \text{Length}\Rightarrow \text{Length}=\dfrac{28}{4}=7\ \text{inches}$

By the Pythagorean theorem,

$\text{Diagonal}^2=\text{Width}^2+\text{Length}^2\\ \\\text{Diagonal}^2=4^2+7^2\\ \\\text{Diagonal}^2=16+49\\ \\\text{Diagonal}^2=65\\ \\\text{Diagonal}=\sqrt{65}\approx 8.06\ \text{inches}$
