Theorem:
In a triangle, a segment whose endpoints are the midpoints of two sides is parallel and half the length of the third side.
In triangle LMN, segment DF has endpoints which are midpoints of sides LM and MN. That makes segment DF parallel to side LN and half the length of LN.
The shortest path from point D to point N is segments DF and FN.
Point F is the midpoint of segment MN.
MN = 800 m
FN = (1/2)MN = (1/2)(800 m) = 400 m
From the theorem,
DF = (1/2)LN
DF = (1/2)(700 m) = 350 m
shortest path = DF + FN = 350 m + 400 m = 750 m
Answer: 750 m

Quadrilateral Practice Test, I’ll give brainliest to the correct answer with explanation
Answer:
120 Degrees
Step-by-step explanation:
Angle T and R are vertical angles meaning they are equal so combine the equations: 31x - 4 = 29x + 4, then solve using inverse operations
subtract 31x from both sides to get -4 = -2x + 4
Then subtract 4 from both sides to get -8 = -2x, now that we have isolated the variable we have to divide by -2 on both sides getting us x = 4, then plug in the four to the equation for angle R getting you 29 times 4 which equals 116 + 4 = 120

Malia ran 7/12 of a mile. Shona ran 3/4 of a mile. Who ran further?
Answer:
Shona ran farther
Step-by-step explanation:
3/4 *3/3 is 9/12 and 9/12 is bigger than 7/12
Answer:
Shona
Step-by-step explanation:
Both fractions have different denominators. To get a better picture of who ran further, let's have both fractions have the same denominator.
Let's convert the smaller denominator to the bigger one.
In order to do this, we will multiply top and bottom by 3:
[tex]\frac{3}{4} *\frac{3}{3} \\\frac{9}{12}[/tex]
Now, we compare the two fractions by seeing which numerator is closer to denominator.
From this comparison, the converted fraction, [tex]\frac{9}{12}[/tex] is closer to 12.
Therefore, Shona ran further.

Decrease the numbers by 2 1/2 and show your Calculations.
1/2, 1 1/3, 1/4, 1, 1/2, 1 1/2
Answer:
-2, -7/6, -9/4, -1 1/2, -2, -1
Step-by-step explanation:
1/2 - 2 1/2 = -2
1 1/3 - 2 1/2= 1 2/6- 2 3/6 = -7/6
1/4- 2 2/4 = -9/4
1 - 2 1/2= -1 1/2
1/2 - 2 1/2= -2
1 1/2 - 2 1/2= -1

A rectangle’s length is three times its width, w. Its area is 243 square units. Which equation can be used to find the width of the rectangle?
w2 = 3(243)
3w2 = 243
4w2 = 243
3w2 = 3(243)
Answer:
the second option because it's three times the width so it would be time the W
