24.05
Step-by-step explanation:
Answer:
The total surface area is 336ft2
Step-by-step explanation:
solution:
total suface area of the pyramid
=area of base square +(12)2 = 4 (1/2 x 12 x 8)
=144+192
=336ft2
then the total surface area is 336ft2
60/700 x 100 (cancel out the zeros to make it easier)
60/7 x 1 = 8.6%
Answer:
25 meters
Step-by-step explanation:
30 km/hr = (30 km/1 hr)*(1000 m/1 km)*(1 hr/60 min)*(1 min/60 sec)
30 km/hr = (30*1000*1*1)/(1*1*60*60) meters per second
30 km/hr = 8.3333333333 m/s (approximate)
----------
The speed or rate is r = 8.3333333333 meters per second approximately, and the time is t = 3 seconds, so,
distance = rate*time
d = r*t
d = 8.3333333333 * 3
d = 24.9999999999
Due to rounding error, the true answer should be d = 25. We can see this if we opted to use the fraction from of 8.3333... instead of the decimal representation which isn't a perfect exact measurement.
