The coefficient is the number that multiply the variable (the variables are the letters, a,b,c etc...)

So we have 6y

The coefficient is 6

The variable is y

What is 287.9412 rounded to the nearest tenth?

Westkost [7]

Hello!

If we want to round 287.9412 to the nearest tenth, the answer would be 287.9

Since rounding to the nearest tenth would mean rounding the first decimal, that's why it gives us that answer.

Also:

287.9412

2 = hundreds

8 = tens

7 = ones

. = decimal

9 = tenths

4 = hundredths

1 = thousandths

2 = millionths

Hope this helped! c:

Step-by-step explanation:

12=2⋅2⋅3

15=3⋅5

We see that they both share 3 is their LCM.

We divide each number by their LCM.

123⇒4

153⇒5

We multiply these two quotients and the LCM to get our final answer:

3⋅4⋅5=60

That is our answer!

Hope this helped! :)

Haley makes earrings and packages them into cube boxes that measure 1/6 foot wide. how many 1/6 foot cubic boxes can she fit int

navik [9.2K]

Answer: $28\ cubes$

Step-by-step explanation:

The volume of a cube can be found with this formula:

$V_{(c)}=s^3$

Where "s" is the lenght of any edge of the cube.

The formula for calculate the volume of a rectangular prism is:

$V_{rp}=lwh$

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

We need to find the volume of a cube box:

$V_1=s^3=(\frac{1}{6}ft)^3=\frac{1}{216}ft^3$

To find the volume of the shipping box, first we must convert the mixed number to an improper fraction:

$1\frac{1}{6}=\frac{(6*1)+1}{6}=\frac{7}{6}$

Then the volume of the shipping box is:

$V_2=lwh\\\\V_2=(\frac{7}{6}ft)(\frac{1}{3}ft)(\frac{1}{3}ft)=\frac{7}{54}ft^3$

Now, in order to find the number of cube boxes can Haley fits into a shipping box, you must divide the the volume of the shipping box by the volume of one cube. This is:

$\frac{\frac{7}{54}ft^3}{\frac{1}{216}ft^3}=28$
