Which statements about the figure must be true? Select three options.
AngleDBC is bisected by ray BD.
AngleABC is bisected by ray BD.
BC = One-halfAC
Line segment D B is-congruent-to Line segment B C
2mAngleDBC = mAngleABC
Answer:
(b).∠ABC is bisected by ray BD.
(c) BC = One-half of AC
(e) 2 ∠DBC = ∠ABC
Step-by-step explanation:
Here ray AC and ray BD is perpendicular to each other.
Thus, Option (a) is not true as ∠DBC is not bisected by any ray.
Option (b) is correct.
Option (c) is also correct as B is the mid-point of AC.
Option (d) is also incorrect as length of line segment DB and line segment BC can be different.
Option (e) is also correct.
Answer:
angle ABC is bisected by BD
BC= halfAC
2mangleDBC=mangleABC

Answer:
40 boxes
Step-by-step explanation:
box = 24 x 15 x 10 = 3600 cm
1 paper clip box = 6 x 3 x 5 = 90 cm
3600/90 = 40
so 40 boxes of paper clips will fit
Answer:
40 boxes
box = 24 x 15 x 10 = 3600 cm
A paper clip box = 6 x 3 x 5 = 90 cm
3600/90 = 40
so 40 boxes of paper clips
Answer:
Building's actual height 32 meters
Building's shadow height 20 meters
Person's shadow height 1.2 meters
Person's actual height = ?
Find the person's actual height:
This is a proportion problem.
Actual height to shadow height
Building = Person
32 : 20 = x : 1.2
32 * 1.2 = 20 * x
38.4 = 20x
38.4/20 = 20x/20
1.92 = x
The person's actual height is 1.92 meters long.
32 : 20 = 1.92 : 1.2
32/20 = 1.60
1.92/1.2 = 1.60
