<span>For this question, let's move the decimal number 2 spaces to the right. 2.16-->216 You need 21 ten rods and 6 cubes. Why: I wouldn't do 2 hundred flats because 2 isn't divisible by 3. Put the ten rods into 3 equal group, then do the same with the cubes. You should end up with 7 in each group since 21 divided by 3 is 7. You should also end up with 2 cubes in each group. So in one group you have 72. Now move the decimal back to where it came from, 2 spaces to the left. Now you have 0.72.

The answer is 0.72 because you divide 2.18 by 3 OR You can set the amount of blocks (2.16) out 3 times and count all of them up and that's your answer
 
                             Hope it Helps!!
                              Good Luck:)

Solve the system of linear equations by using the elimination method: <br> 4x+ y = 36<br> 8x- y = 60
katrin [286]

Answer:

(8,4)

Step-by-step explanation:

y and -y cancels out leaving you with "12x=96"

that simplifies to "x=8"

Then you substitute 8 into the "x" from either equation and y should equal 4

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
