I REALLY NEED HELP!!Determine how many actual fish food boxes fit in the shipping box. Show your work.

Effectus [21]

Answer: 2,340 fish food boxes

Step-by-step explanation:

The missing figure is attached.

Convert all the Mixed numbers and the fraction to Decimal numbers:

$3\frac{3}{4}\ ft=(3+0.75)\ ft=3.75\ ft\\\\3+\frac{1}{4}\ ft=(3+0.25)\ ft=3.25\ ft\\\\\frac{1}{ 4}\ ft=0.25\ ft$

The fish food boxes are cubes.

Find the volume of a fish food box with this formula:

$V_f=s^3$

Where "s" is the length of any edge.

This is:

$V_f=(0.25\ ft)^3\\\\V_f=0.015625\ ft^3$

The Shipping box is a rectangular prism. Find its volume with this formula:

$V_s=lwh$

Where "l" is the length, "w" is the width and "h" is the height.

Then, this is:

$V_s=(3.75\ ft)(3\ ft)(3.25\ ft)\\\\V_s=36.5625\ ft^3$

FInally, you must divide the volumes in order to calculate the number of fish food boxes that fit in the shipping box. You get this result:

$\frac{36.5625\ ft^3}{0.015625\ ft^3}=2,340$ $fish\ food\ boxes$

The circle C has equation

loris [4]

Answer:

$y=-4x+12\\y =-0.421x+12$

Step-by-step explanation:

The lines through (0,12) would have equation of the form

y = mx+12

If this is tangent, the distance of centre from the tangent = radius of the circle

Distance of (6,5) ie centre from tangent line is

$\frac{6m+7}{\sqrt{1+m^2} } =\sqrt{17} \\(6m+7)^2 = 17(1+m^2)\\$

$36m^2+84m+49 =17+17m^2\\19m^2+84m+32=0$

m=-4,-0.421

Hence tangents are

$y=-4x+12\\y =-0.421x+12$
