Wouldn't that be 9 calls then? one minute for each call.
Answer: segment BC = 36 units
Step-by-step explanation:
As per the given information, we have
B, C and D are three points such that
segment BC = segment BD + segment DC ... (i)
And segment BD = segment DC ... (ii)
If segment BD = 18 units
Then, segment DC = 18 units [From (ii)]
segment BC = 18 units + 18 units [From (i)]
⇒segment BC = 36 units
Hence, length of 
= 36 units
The answer is literally-5.7
Answer:
you have to divide all the numbers and see what it is
Answer:
y = -1/3x + 2
Step-by-step explanation:
The gradient of the given line is 3 because (y = mx +c where m is the gradient)
Therefore, to find the gradient of the perpendicular line (at 90 degrees), you need to find the negative reciprocal.
The negative reciprocal of 3 is -1/3 because imagine if 3 = 3/1, to get the reciprocal, you flip it, and to get the negative, you just flip the sign.
Now we know that Line M is y = -1/3x + c, we need to find the y-intercept.
To do this, just input the point (3,1) into y = -1/3x + c, to get c. This is because we know (3,1) is on the line from the question.
So it would be 1 = (-1/3 x 3) +c
Which would be 1 = -1 +c
And so c = 2
Put everything together and you get y = -1/3x + 2
