Answer:

At 3:30 p.m. she started playing the piano

Step-by-step explanation:

We are given the following information:

Marcy played the piano for 45 minutes.

She stopped playing at 4:15 p.m.

This means that at 3:30 p.m. she started playing the piano.

( since 15 minutes before 4:15 om is 4:00 pm now 30 minutes more before 4:00 pm is 3:30 pm which adds up to:

15+30=45 min.)

Well, first off 1 hr =60 minutes. 60 min - 45 min = 15 minutes extra. what is one hour before 4:15? 3:15! Add the subtracted 15 minutes to get 3:30... Hope this helps

Fiesta28 [93]

Answer:

Option B

y coordinate is 0

Step-by-step explanation:

We have in two dimension rectangular system of coordinates with two mutually perpendicular lines called x and y axis.

X axis is the horizontal line and y the vertical line, the point of intersection of these two lines is called origin with x=0: y=0

To the right of origin, positive values are marked and left negative. Similarly for y axis, above origin positive values and below negative values.

Thus we have along x axis, y values to be 0

Hence any point on x coordinate will be of the form (a,0) where a can be any real number

So option B is right
