Answer:
71 times
Step-by-step explanation:
Diameter of BMX bike= 0.45m
Radius= 0.225m
Cirumference of BMX bike
C= 2πr
C=2*3.142*0.225
C= 1.4139m
In a 400-m race, the BMX bike will turn
=400/1.4139
=282.9 times
=283 times
Diameter of Mountain bike= 0.6m
Radius= 0.3m
Circumference of Mountain bike
C= 2πr
C=2*3.142*0.3
C=1.8852m
In a 400-m race, the Mountain bike will turn
=400/1.8852
=212.17 times
=212 times
Hence the difference is
=283 -212
=71 times
12 is equivalent to three and 36 is equivalent to 12 three goes into 12 four times and and 36 goes into 12 three times
Answer:
Step-by-step explanation:
(2u+3u)(u+v)-2u+3v
=2u(u+v)+3u(u+v)-2u+3v
=2u^2+2uv+3u^2+3uv-2u+3v
=5u^2+5uv-2u+3v
Answer:
True
Step-by-step explanation:
The whole point of units conversion is to take a value expressed in one set of units (parts per hour) and translate it to a different set of units (parts per week). The rate does not have to involve time.
The statement is TRUE.
