A boat is traveling at 43.2 m/s. It then goes down a faster part of the river and is now going 144
m/s which gave the boat an acceleration of 25.2 m/s2. How long did it take the boat to reach its
new speed?

Answers

Answer 1

Answer:

Step-by-step explanation:

boat was at 43.2 m/s   speed increase to 144 m/s

if the boat was moving 0 m/s and increased to 144 m/s - 43.2 m/s accelerating at 25.2 m/s²,  it would take the same amount of time

25.2 m/s² × x seconds = (144 - 43.2) m/s      solve for x in seconds

x seconds = 100.8 m/s   /  25.2 m/s²

x seconds = 4 (m/s /ms²)  = 4 (m/s × s²/m)  = 4 seconds   the  units match

x = 4 seconds

y = -2/3x + 5 1/3

Step-by-step explanation:

Find the slope:

4 - 6 / 2 - (-1) = -2/3

Put it in point-slope form:

y - 6 = -2/3(x + 1)

rearrange:

y - 6 = -2/3x - 2/3

y = -2/3x + 5 1/3

Janie has 2 3/4 yards or yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks

Answers

Answer:

Step-by-step explanation:

Janie has 2 3/4 yards of yellow ribbon. She uses 1/2 of the ribbon to decorate bookmarks for her cousin. How many yards of ribbon did Janie use for her bookmarks

The above question is calculated as:

2 3/4 yards × 1/2 of ribbon

= 11/8

= 1 3/8 yards

Therefore, Janie used 1 3/8 yards of ribbon for her bookmarks
