<h2>Answer:  Lines b & c are parallel.⇄</h2>

Step-by-step explanation:

  • When lines are perpendicular, the product of their slope is -1 (the slopes are negative reciprocal).
  • When lines are parallel, they have the same slope.

Slope = ( y₂ - y₁) / (x₂ - x₁)

Slope of Line b = ( 6 - 1 ) ÷ ( 1 - 9 )

                         =  5  ÷  (- 8)

                         =   - ⁵/₈

Slope of Line c =  ( 12 - 7 )  ÷  ( 2 - 10 )

                         =  - ⁵/₈

⇒ Line b ║ Line c

THESE ARE SEPARATE QUESTIONS THAT I DECIDED TO COMBINE:

1).  Her walking pace is  (1.75 miles) / (50 minutes).

If you want it in units of (miles per hour), do it like this:

               (1.75 miles / 50 minutes) x (60 minutes / 1 hour)

           =  (  1.75 x 60 / 50 ) miles per hour.

2).  The average change was 

                         (30 - 45) degrees  / (5 minutes) .

I'm sure you can do the division and make an integer out of that.

3).  Each bracelet cost $3.10.
Caroline bought five of them, so she spent $3.10 five times.
Either do the multiplication, or else write down $3.10 five times
and do the addition.

4).  In order to factor the expression, the two terms would need
to have some common factor ... both terms need either a power
of 'x', or they need two numbers that have a common factor.
They don't both have an 'x', and 13 and 10 have no common factor.

5).  Todd earned 'T' dollars.
Twice what Todd earned is  2T .
$350 more than that is   2T+350 .
The question says that 2,500 is exactly that amount,
so you can write
                                                  2T + 350 =  2,500

Subtract 350 from each side:    2T           =  2,150

Divide each side by  2:              (you can finish it now)

Mr White can travel for 6 hours while taking 3 breaks of 10 minutes each. Once, he had to travel for 36 hours. How many minutes
alexgriva [62]

180 min

Explanation:

3 × 10 min = 30 min

In 6 hours, Mr. White takes a total of  30 min  in breaks.

36 h = 6 h × 6  

In  36 hours , there are  6  sets of  6 h .

Hence we can multiply the number of minutes in breaks taken in  

6 h ours by  6  to obtain the number of minutes in breaks taken in  36 h ours.  

30 min × 6 = 180 min
