Answer:

1 7⁄10 = m

Step-by-step explanation:

m = -y₁ + y₂\-x₁ + x₂ → -17 - 17\-12 - 8 >> 1 7⁄10

-34 -20

Can two lines be drawn from a point not on a line that will meet the line at a right angle? at a 45° angle? explain each answer.
vichka [17]
I believe the the correct answer would be yes. Two lines can be drawn from a point that is not collinear with a certain line that will meet the line at a right angle or 90 degree angle and at an angle of 45 degrees. We can freely draw any line that would pass through a given point and would cross a given line at any direction giving us different angles and this would include a 90 and 45 degree angle.

Please Help! (10 POINTS)
Sliva [168]
The initial measure is:
 m1 = 28 ft
 The real measure must be:
 m2 = 14 ft
 The correct procedure to determine the scale factor is:
 k = m1 / m2

k = 28/14
 Dividing both numbers between 14 we have:
 k = (28/14) / (14/14)
 Rewriting:
 k = 2/1

k = 2
 Answer:
 
Zelie should have divided both numbers by 14.

Find the length of line segment UV.
pshichka [43]

Answer:

The length of the line segment UV is 76 units

Step-by-step explanation:

In a triangle, the line segment joining the mid-points of two sides is parallel to the third side and equal to half its length

In Δ ONT

∵ U is the mid-point of ON

∵ V is the mid-point of TN

→ That means UV is joining the mid-points of two sides

∴ UV // OT

∴ UV = \frac{1}{2} OT

∵ UV = 7x - 8

∵ OT = 12x + 8

∴ 7x - 8 = \frac{1}{2} (12x + 8)

→ Multiply the bracket by \frac{1}{2}

∵ \frac{1}{2} (12x + 8) =  \frac{1}{2} (12x) +  \frac{1}{2} (8) = 6x + 4

∴ 7x - 8 = 6x + 4

→ Add 8 to both sides

∴ 7x - 8 + 8 = 6x + 4 + 8

∴ 7x = 6x + 12

→ Subtract 6x from both sides

∴ 7x - 6x = 6x - 6x + 12

∴ x = 12

→ Substitute the value of x in the expression of UV to find it

∵ UV = 7(12) - 8 = 84 - 8

∴ UV = 76

∴ The length of the line segment UV is 76 units

I have seen this question before and the amount of girls was 220, so 400-220 is 180

Hope this helps :)
