Answer: D. Cannot be determined.

If Angle 3 were not included, the answer would be A, 360°

Step-by-step explanation: When the lines a, b, & c are parallel, the line intersecting them forms angles that are vertical, supplementary and/or corresponding and congruent.

Here, angles 4 and 5 are supplementary. No need to know their exact measurements. Together, their sum is 180°

Angles 1 and 2 are also supplementary, another 180°

But we don't know the measure of angle 3, so getting an exact sum is impossible here.

$speed = \frac{distance}{time}$

from the question,

$speed = \frac{40}{10}$

speed = 4km/hr

B. 10hrs - 6hrs = 4hours

C. BC is deacceleration = -dv/dt

CD is constant acceleration = dt = 0

The ratio of water to orange juice to cranberry juice in a punch bowl should be 2:5:3.

den301095 [7]

Water= 2
Orange juice= 5
Cranberry Juice= 3

Since the cranberry juice is 24 ounces, and 3 ounces in the other ratio, we know that 3*8=24, so we would multiply all of the others by 8.

Cranberry juice: 3*8=24
Orange juice: 5*8= 40
Water: 2*8=16

So our ratio would be 16:40:24
