Answer:
y= 6/5x-5
Step-by-step explanation:
Answer: If he gives Al 42, then he gives Bob 21 and Carl 84. Do those add up to 210? 42 + 21 + 84 = 147–that’s too small! Go bigger.
Step-by-step explanation:
So Since (D) is odd, shoot right to (E). If he gives Al 60, then he gives Bob 30 and Carl 120. Does that add up to 210? Yes, yes it does. 60 + 30 + 120 = 210.
Complete question:
Points A, B, and C are midpoints of the sides of right triangle DEF. Triangle A B C is inside triangle D E F. Point A is the midpoint of side F D, point B is the midpoint of side D E, point C is the midpoint of side F E. Angles D F E and A B C are right angles. The length of D E is 10 centimeters, the length of F D is 6 centimeters, and the length of F E is 8 centimeters. Which statements are true? Select three options. (The formula for the area of a triangle is A = One-halfbh.)
- BC = 6 cm
- AC = 5 cm
- BA = 4 cm
- The perimeter of triangle ABC = 12 cm.
- The area of triangle ABC is One-third the area of triangle DEF.
Answer:
2. A-C = 5 cm
3. B-A = 4 cm
4. The perimeter of triangle A-B-C = 12 cm.
Step-by-step explanation:
First, picture a triangle formed by points D-E-F.
- Side F-D = 6 centimeters
- Side D-E = 10 centimeters
- Side F-E = 8 centimeters
Now,
- the midpoint of side F-D is A ⇒ 6/2 = 3cm
- the midpoint of side D-E is B ⇒ 10/2 = 5cm
- the midpoint of side F-E is C ⇒ 8/2 = 4cm
These values suggest that
- Side F-A ⇒ 3 cm = Side B-C ⇒ 3cm
- Side E-B ⇒ 5 cm = Side A-C ⇒ 5cm
- Side F-C = E-C ⇒ 4cm = Side A-B ⇒ 4cm
The perimeter of the interior triangle ABC = 3cm + 5cm + 4cm = 12 cm
The total area of the interior triangle ABC is 1/4 the area of triangle DEF. You can see in the picture that there are four equal triangles inside DEF.
