Answer:
No. of complete revolutions = 20
Step-by-step explanation:
Given:
Distance covered by the bicycle = 40 m
Radius of the bicycle wheel = 32.5 cm = 0.325 m
Conversion:
⇒
We have to find the number of revolution the front wheel make.
Let the no. of revolution be "N" .
As we know that:
Circumference times no. of revolution = Distance covered by circular objects.
Circumference = 2πr
So,
⇒
⇒
⇒ Plugging the values.

⇒
Approximated to 20.
Number of complete revolutions,the front wheel make = 20
P+ b= 207
p-59= b
P+ (P-59)=207
2p-59=207:
2p =207+59
p=266/2
P=133
b=133-59
b=74
psych books= 133
biology books= 74
74+133= 207(Check)

Answer:
7/8 inch
Step-by-step explanation:
Subtract 3/8 from 1 1/4:
5/4 - 3/8
becomes 10/8 - 3/8 = 7/8 (inch)
Step-by-step explanation:
f (x)=5x+1
Hence, In order to find f (-3), we must find the value of 5×-3 +1
Hence, Substituting x=-3,
p (-3)=5×-3 +1
= -15+1
= -14
