You work part-time at the “Pack-it and Mail-it” that sells containers used for shipping items. Your photography teacher asks you

vaieri [72.5K]

Answer:

(a)18.85 Cubic Inches

(b)The box with dimensions of 4 in. x 3in. x 2 in.

Step-by-step explanation:

Part A

Height =2 Inches

Diameter=1 Inch

Radius=Diameter/2=1/2=0.5 Inch

Volume of a cylinder $=\pi r^2h$

Volume of 1 Container $=\pi* 0.5^2*2= 0.5\pi $ cubic inches$

Volume of the 12 Containers $=12*0.5\pi =18.85$ cubic inches$

Part B

Next, we determine the container that should be used. Let us first determine the volume of each of the boxes available for easy comparison.

Volume of the boxes

Volume of box with dimension 3 in. x 2 in. x 5 in.=3X2X5=30 Cubic Inches
Volume of box with dimension 4 in. x 3in. x 2 in.=4X3X2=24 Cubic Inches
Volume of box with dimension 5 in. x 6 in. x 5 in.=5X6X5=150 Cubic Inches
Volume of box with dimension 3 in. x 2 in. x 3 in. =3X2X3=18 Cubic Inches

The volume of the 12 film containers is greater than 18 but less than 24. Therefore,the box that should be used with the least amount of wasted space is the box with a volume of 24 Cubic inches.

Pipe A can fill a swimming pool in 12 h. Working with another Pipe B, it only takes 3h How long would it take Pipe B working al

MatroZZZ [7]

My guess is 9 hours, because since pipe a takes 12 hours and with pipe b it takes 9, it's 12-9=3 I think.

Nancy is making a kite based on the pattern below. About how much binding does Nancy need to cover the edges of the kite?

Ainat [17]

Check the picture below.

so the perimeter of the kite is x+x+y+y, namely 2x + 2y.

$\bf \textit{using the pythagorean theorem} \\\\ c^2=a^2+b^2\implies c=\sqrt{a^2+b^2} \qquad \begin{cases} c=\stackrel{hypotenuse}{x}\\ a=\stackrel{adjacent}{8}\\ b=\stackrel{opposite}{15}\\ \end{cases} \\\\\\ x=\sqrt{8^2+15^2}\implies x=\sqrt{289}\implies \boxed{x=17} \\\\[-0.35em] ~\dotfill$

$\bf \begin{cases} c=\stackrel{hypotenuse}{y}\\ a=\stackrel{adjacent}{8}\\ b=\stackrel{opposite}{4}\\ \end{cases}\implies y=\sqrt{8^2+4^2}\implies y=\sqrt{80}\implies \boxed{y\approx 8.94} \\\\[-0.35em] ~\dotfill\\\\ 2x+2y\implies 2(17)+2(8.94)\implies 51.88\implies \stackrel{\textit{rounded up more}}{51.9}$
