Answer:
105
Step-by-step explanation:
PEMDAS
So 70.52 and 13.27
so 13.27 is what percent of 70.52
percent means parts out of 100
what percent of 70.52
'of' can be tranlated to mutiply
13.27=x% times 70.52
13.27=x/100 times 70.52
13.27=70.52x/100
13.27=0.7052x
divide both side by 0.7052
18.82
the answer is 18.8%
the easy way is
to find percent assume 70.27=100
so x/100=
13.27/70.52 then multiply by 100=0.18817 multipliy 100
18.817=round 18.8%
answer is 18.8%
Answer:
a) 2211.6812281 rad/min
b) 352 rpm
Step-by-step explanation:
A bicycle with 24-inch diameter wheels is traveling at 16 mi/h. Find the angular speed of the wheels in radians per minute. ___ radians per minute
How many revolutions per minute do the wheels make? (Round your answer to three decimal places.) ___ revolutions per minute
truck with 24-in.-diameter wheels is traveling at 16 mi/h.
---------
1 mile per hour = 88 feet per minute
16 mi/hr = 1408ft/minute
----------
Each revolution = pi*d feet = 4pi feet
(b) How many revolutions per minute do the wheels make?
rev/min
-------------
Each revolution = pi*d feet = 4pi feet
rpm = 1408 ft/min / 4pi feet
=~ 352 rpm
---------------
(a) Find the angular speed of the wheels in rad/min.
rad/min
-------------
rad/min = rpm*2*pi
= 352 rpm × 2× π
= 2211.6812281 rad/min
