Answer:
.31
Step-by-step explanation:
155 / 5 31/100
500/ 5
31÷100
Long Division for 31 divided by 100
round to a Max of 3 Decimal gives us
=0.31
(2-c,y) is the answer for the problem.
Answer:
The answer is A. 10b = c
Step-by-step explanation:
Well if it's $10 per book and the total cost is C. Then you would multiply the amount of books with the cost per book and have it equal the the total C.
Now to solve this problem, all we have to remember is the
formula for calculating the linear speed given the radial speed, that is:
v = r w
where,
v = is the linear velocity or linear speed
r = is the radius of the circular disk = (1 / 2) diameter
= (1/ 2) (2.5 inches) = 1.25 inches
w = is the radial velocity (must be in rad per time) =
7200 rev per minute
Calculating for v:
v = 1.25 inches (7200 rev per minute) (2 π rad / 1 rev)
v = 56,548.67 inches / minute
Converting to miles per hour:
v = 56,548.67 inches / minute (1 mile / 63360 inches) (60
min / hour)
<span>v = 53.55 mile / hour</span>
437 and 250 and 422 there you goooooo
