Make them the same demonatator so 7/8 times 2/8 which equals 14 over 8 for a mixed number of 1 6/8
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>
answer: 360
Given:
Machine A Candy Packing
x(minutes) y(candies)
5 600
10 1200
15 1800
20 2400
Machine B : y = 150x
Find number of candies packed in 12 minutes.
Machine A : 600/5mins = 120 candies per minute
120 * 12 minutes = 1,440 candies
Machine B : y = 150x ⇒ y = 150(12) ⇒ y = 1,800
Machine B: 1,800
Machine A: 1,440
Difference 360
Machine B packed 360 more candies than Machine A in 12 minutes.
Okay we'll start easy
46*93
We will take 6*3 which is 18.
40*3 which is 120
6*90 which is 540
40*90 which is 3600
Now add up those
18+120+540+3600 which is 4278
So the missing numbers.
3._00 is going to be 3600
5_0 is going to be 540
_20 is going to be 120
1_ is going to be 18
4._78 is going to be 4.278
Hope this helped. ^~^
