15. 10:15 or 10 to 15
16. 55:11 or 55 to 11
17. 4:8 or 4 to 8
18. 13:65 or 13 to 65
Let the water surface be 0.
He starts at 15 and gets to the water surface of 0 so he travels 15 meters.
He then goes 5 meters below the surface.
15 + 5 = 20 total meters.
Answer:
none of these
Step-by-step explanation:
There are 3 boys walking
There are a total of 20 people
3/20 = 0.15
That is 15 percent, therefore none of these answers.
Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
Where m is the slope and (a, b) a point on the line
y - 4 = - 5(x + 3 ) ← is in point- slope form
with m = - 5 and (a, b) = (- 3, 4 ) → C
