1 lap = 400 meters
Therefore, we can use something called "dimensional analysis" to convert from laps to meters. We use equivalent quantities to do so. Since 1 lap = 400 meters, we can say
1 = 400 meters / 1 lap.
This gives us a "conversion factor" between laps and meters. Since we know we have traveled 8 laps, we can multiply this by our conversion factor (which we have defined to be equal to 1!):
8 laps * 1 = 8 laps * 400 meters / 1 lap
Now we can cancel words the same way we cancel numbers in a fraction. If we have 4 / 4, we cancel the 4's and get 1. Similarly, in the above we can cancel the "lap" with the "lap" on the bottom of the fraction of the conversion factor. Then we have:
8 laps = 3200 meters
Answer:
520
Step-by-step explanation:
Is means equals and of means multiply
78 = 15% * W
Change to decimal form
78 = .15 *W
Divide by .15 on each side
78/.15 = .15W/.15
520 = W
= 512000000

Answer:
10^4
Step-by-step explanation:
lets say the number is 1.0 if you where to move the decimal to the right 4 place the number would then be 10,000.0. basically if it says 10^4 add 4 0's
Answer:
Step-by-step explanation:
hello :
a(n) -a(n-1) = -16 (common differnce for arithmetic sequence)
-44-(-28) = (-28)-(-12) = -16
the ni-eme term is : a(n) = a(1) +(n-1)d d = -16 and a(1) = -12
so : a(n) = -12 +(n-1)(-16)
a(n) = -16n+4
continue for 61st term n = ?????
when : n= ? a(?) = -16(?)+3 =.....
