Answer:

AB and CD are parallel

Step-by-step explanation:

AB has the slope of -2/5

lets see what slope the line CD has:

  • points are (-5, 3) and (10, -3)
  • slope= m= (y2-y1)/(x2-x1)= (-3-3)/(10+5)= -6/15= -2/5

as we see AB and CD have same slope, therefore they are parallel

Whitepunk [10]
.312

Frequency is 24

To find relative frequency (of Pop music) you would take 24 and divide it by the total students you were surveyed.

24/77 = .3116 rounded to hundredths becomes .312

If they are looking for percentage, you take the .312 and multiply by 100 to get 31.12%

Suppose you are driving to visit a friend in another state. you are driving 55 miles per hour. you must drive 440 miles total. i
Oliga [24]
Time=(distance)/(speed)
speed=55 mi/hr
Total distance=440 miles
Distance covered=275 miles
remaining distance=440-275=165 miles
Time taken to cover the remaining distance will be:
time=165/55=3 hours

Total time taken to travel=440/55=8 hours
if we are to use the equation given by:
55h+275=440
time taken will be found by solving for h, thus we shall have:
55h=440-275
55h=165
h=165/55
h=3 hours

Answer: 3 hours
