If line P bisects segmentAD at point O and if AO=z+4 and AD =3z-11, find OD
sleet_krkn [62]

Answer:

Line P bisects AD at O.

AD = AO + OD

(3z - 11) = (z + 4) + OD

(3z - 11) - (z + 4) = OD

3z - 11 - z - 4 = OD

2z -15 = OD

The point A (5,11) is reflected across the x-axis. How long is the segment AA'?<br>​
Nikitich [7]

Answer:  The required length of the segment AA' is 11 units.

Step-by-step explanation:  Given that the point A(5, 11) is reflected across the X-axis.

We are to find the length of the segment AA'.

We know that

if a point (x, y) is reflected across X-axis, then its co-ordinates becomes (x, -y).

So, after reflection, the co-ordinates of the point A(5, 11) becomes A'(5, -11).

Now, we have the following distance formula :

The DISTANCE between two points P(a, b) and Q(c, d) gives the length of the segment PQ as follows :

PQ=\sqrt{(c-a)^2+(d-b)^2}.

Therefore, the length of the segment AA' is given by

AA'=\sqrt{(5-5)^2+(-11-11)^2}=\sqrt{11^2}=11.

Thus, the required length of the segment AA' is 11 units.

What fraction is equivalent to four tenths and has a denominator of 100?
Sever21 [200]

Answer:

\frac{40}{100}

Step-by-step explanation:

You can multiply on the upper and bottom part by the same number without changing the fraction so \frac{4}{10}=\frac{4\cdot 10}{10\cdot 10}=\frac{40}{100}

Math. Help much appreciated
ella [17]

First of all, expand the left hand side:

4x+4 - 7 < 3x + 5

Sum like terms:

4x -3 < 3x + 5

Add 3 to both sides:

4x < 3x + 8

Subtract 3x from both sides:

x < 8

So this is the solution. Every number smaller than 8 (excluded) is part of the solution of this inequality.
