Answer:
1200 ft in one hour
Step-by-step explanation:
The ratio of Sam crawling 20 ft in one minute can be written as:
20:1
Multiply the ratio by 60 to get the minutes to 60 minutes, because there are 60 minutes in an hour:
20 : 1
×60 ×60
To get:
1200:60 ⇒ This means Sam can crawl 1200 ft in 60 minutes, which is the same as 1200 ft in one hour.

So line b is (0,0) and (4, -3/2)
slope = m = y2-y1/ x2-x1
= -3/2 - 0 / (4-0 )= -3/8
now using point slope y-y1=m(x-x1)
m=-3/8 and point is (0,0) to make it easier
y-0 = -3/8 (x-0)
y=-3/8x
so we have the first line done, now another line is parallel to line b which means they have the same slope
line 2 has slope = m = -3/8
and point (0,-7)
using point slope again y-y1=m(x-x1)
y- (-7) = (-3/8) (x-0)
y=(-3/8)x -7
hope that helps and is right
Complementary angles:
The sum of two complementary angles is 90.
When two complementary angles are adjacent, a right angle is formed.
Supplementary angles:
The sum of two supplementary angles is 180.
When two supplementary angles are adjacent, a straight angle is formed.
