Step-by-step explanation: To write 2/9 as a decimal, we begin by dividing 9 into 2.

Since 9 doesn't divide into 2, we write a decimal point and a zero after the 2 so that we can divide 9 into 20.

9 divided into 20 two times . so we write a 2 in our answer above the zero. 2 multiplied by 9 is 18 and 20 - 18 is 2.

Now, we write another zero under the division sign and bring down the zero so we have 20. Again, 9 divides into 20 two times, 2 x 9 is 18, and 20 - 28 is 2.

Notice that there seems to be a pattern forming. To make sure that this is true, we write another zero under the division sign and bring down the zero so we have 20. 9 divided into 20 two times, 2 x 9 is 18, and 20 - 18 is 2.

Our decimal does not seem to be ending and our same digit is repeating.

Therefore, 2/9 converted into a decimal is 0.2 repeating.

Weird. A period appears above this... huh.

Answer:

[Th]e cube has a greater value.

Step-by-step explanation:

What the word problem really wants us to get [is ]the question of 'Which is greater, A=6a^2 when 'a' [is] 18 or A=4 $\pi$ r^2 when r = 9? And here's how to solve that.

Starting with the[ c]ube we have A=6a^2. A bit t[o]o simple, right?

A=6(18)^2 Substitute numbers.

A=6(324) Solve ex[p]onents.

A=1944 Mult[i]ply.

So w[e] know that the cube is 1944 meters cube[d ] in area. But what about the more [f]ormidable sphere? Fo[r] it we need a slightly m[o]re co[m]plicated formula, A=4 $\pi$ r^2. However, instead of using the real pi I will be rounding to 3.14, since we have no calculator so anything more would take way too long and fry your[ bra]in.

A=4(3.14)(9)^2 Subst[i]tute numbers.

A=4(3.14)(81) Solve expone[n]ts.

A=12.56(81) Multip[ly].

A=1017.36 Multiply again[.]

Now, since I'm sure all of us can count, we know that 1944 is greater than 1017.36. Or in other words, the cube is bigger than the sphere.

And PLEASE don't copy this guys. Make your own iteration. Change it up!

Eggplant has a yield of 81%. If you purchase 12lb of eggplant, how many pounds will you be able to use?(round to the nearest hun

Answer:

9.72 lb

Step-by-step explanation:

Yield = the amount or quantity produced or returned.

Given:

Yield of eggplant = 81%
Amount of eggplant purchased = 12 lb

To determine how many pounds of eggplant you will be able to use, calculate 81% of the amount of eggplant purchased.

$\begin{aligned}\sf 81\% \: of \: 12 \: lb & = \sf \dfrac{81}{100} \cdot 12\\\\& = \sf \dfrac{81 \cdot 12}{100}\\\\& = \sf \dfrac{972}{100}\\\\& = \sf 9.72\:lb\end{aligned}$
