<u>dog</u>

Average velocity is given by the change in position divided by the time required for that change.

v = ∆x/∆t = (4 m)/(4.1 s -2.3 s) = 4/1.8 m/s ≈ 2.2 m/s

<u>car</u>

The instantaneous velocity is zero where the graph is horizontal (no change in position while time marches on—zero slope). Marked points C and G are such points. The appropriate choice is point C.

Which statement about the angle measures is true?
sattari [20]

Answer:

Option (4)

Step-by-step explanation:

By the property of exterior angle of a triangle,

"Exterior angle of a triangle is equal to the sum of two opposite interior angles."

In the triangle ABC,

∠ACD is an exterior angle and ∠BAC and ∠ABC are the opposite interior angles.

m∠ACD = m∠BAC + m∠ABC

95° = m∠BAC + m∠ABC

Therefore, Option (4) will be the correct option.

24 times 10 times 90 equals 90 times 2,400
klasskru [66]

WRONG!

24 x 10 x 90

(24 x 10) x 90

  240     x 90

That is NOT the same as 2400 x 90
