Answer:

parallel
not perpendicular

Step-by-step explanation:

1) It appears that coordinates of points on line P are (-6, 6) and (-2, 8). The slope formula tells us the slope of line P is ...

m = (y2 -y1)/(x2 -x1) = (8 -6)/(-2 -(-6)) = 2/4 = 1/2

Coordinates on line O appear to be (0, 6) and (4, 8). Its slope is ...

m = (8 -6)/(4 -0) = 2/4 = 1/2

The slopes of lines P and O are the same, so the lines are parallel.

2) It appears that points on line M are (0, 6) and (2, 2). Its slope is ...

m = (2 -6)/(2 -0) = -4/2 = -2

Points on line K appear to be (0, 4) and (10, 10). Its slope is ...

m = (10 -4)/(10 -0) = 6/10 = 3/5

If lines M and K were perpendicular, the product of their slopes would be -1. Here, it is (-2)(3/5) = -6/5 ≠ -1. Lines M and K are not perpendicular.

Answer:

if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, she may or may not if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf. But,the chance is very likely less than 50%.

Step-by-step explanation:

If your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, the chance that she might follow the instructions she receives is less 50 percent. In other words:

Chance < 50%

The reason is that children at this age may have challenging time figuring out the subject when you may instruct certain things to do, as the sentences could be tricky for the children to decode the meaning.

So, if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf, she may or may not if your 4.5-year-old sister was asked to Put the bunny on the blanket on the shelf. But,the chance is very likely less than 50%.

Sergio039 [100]

Answer:

40%

Step-by-step explanation:

Degree representing students who prefer burgers = 144°

Percentage of students who like burger = $\frac{144}{360} \times 100$

$= 0.4 \times 100$

$= 40 percent$

Percentage of students who offered burger = 40%

USPshnik [31]

25 feet above sea level means she travelled 25 feet to the surface of the sea. She would have to descend (37-25=12) 12 more feet to achieve 37 total feet of travel, so she descended 12 feet below sea level.
