The first thing we must know is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Therefore, the total distance traveled in this case is:
(5.5) * (0.5) + (1.5) * p = 13.25
Rewriting:
2.75 + 1.5p = 13.25
Clearing the value of p we have:
p = (13.25-2.75) / (1.5)
p = 7
Answer:
an equation representing this situation is:
2.75 + 1.5p = 13.25
DeAngelo's rate for the last 1.5 hours of his run is 7 miles per hour

Suppose you were able to take a large piece of paper of ordinary thickness and fold it in half 50 times. what would the height o

Lapatulllka [165]

see the attached table

the function will be

y=2<span>^n
n= number of folds
y= </span>thick (number of sheets)

the answer is

the height of the folded paper will be 4.50 E+12 in------> 1.62 E+13 m

the result obtained exceeds all the comparisons indicated in the problem (see the attached table)
