Answer:

A. always

Step-by-step explanation:

we know that

Parallel lines  are those lines which never intersect to each other and always have same distance between them

Two lines always have same distance will only be possible when they lie on same plane

and we know that

same plane means co-planar

so, two lines will be parallel only if they are co-planar

It means that

Parallel lines are always co-planar

So,

Josh invested $12,000 in mutual funds and received a sum of $20,000 at the end of the investment period. Calculate the ROI.
tresset_1 [31]

Answer:

ROI = 66.67%

Step-by-step explanation:

Given:

josh investment= $12,000

Received sum= $20,000

ROI=?

ROI is the return on investment that gives the loss or gain in any investment and is calculated by the following formula:

ROI= (interest/investment) x 100

Finding interest:

interests= received sum- investment

              = 20,000-12,000

              =8000

Putting values in ROI formula we get:

ROI= (8000/12000) x 100

      = 66.67%

Hence the return on investment is 66.67%!

Three of the following steps are used in writing a mixed number as an improper fraction. Which step does NOT belong?
QveST [7]
I don't see the steps, but the steps that I use are:
1. Multiply the denominator by the whole number 
2. Then you add the numerator to your sum.
3. The number that you just got by doing those steps is now going to be your numerator and your old denominator is going to stay your denominator.

Example:

2 2/3 
3*2=6
6+2=8
8/3 is your new answer.

Please help me this is so confusing to me.

Hi there! :)

\large\boxed{A = 120^{o}}

Find the central angle using a ratio in regards to angle and circumference.

The radius is 27 units, so use the following equation to calculate circumference:

C = 2rπ

Therefore:

C = 2(27)π = 54π

Since we have the total circumference, we can write the following proportion:

\frac{x}{360} = \frac{18\pi}{54\pi}

Cross multiply:

54πx = 6480π

Divide both sides by 54π to isolate for x:

x = 120°
