Answer:
Division property
Step-by-step explanation:
The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.
The goal of dividing an equation is to isolate the unknown variable on one side.
For example, let the equation be:
2×x=10
Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:
2×x<u>÷2</u>=10<u>÷2</u>
<u />
Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.
In degree measure, the angles pi/3,pi/4 , and pi/2 are respectively: A. 60, 45, 90 B. 30, 45, 90 C. 45, 60, 90 D. 60, 30, 90 (al
aev [14]
<span>Solution :-
The value of pi expressed in radians and its equivalent degree is = 180 degree
Hence, the value of pi/3 = 180/ 3 = 60 deg
similarly, the value of pi/3 = 180/4= 45 deg
similarly, the value of pi/2= 180/2= 90 deg
Ans :-
The angles of pi/3, pi/4, pi/ 4 is = 60, 45, 90 degree respectively. Hence the right option is answer is A.</span>
Note: 1 inch = 2.54 cm is an exact converion, while 1 mile=1.6km is only approximate.
Using conversion
1 inch=2.54 cm
1 mile = 1760*3*12 = 63360 in = 160934.4 cm
If 1 inch = 1 mile, then
2.54 cm : 1 mile = 1.609344 km
1 cm : 0.6336 km (exactly), or
1 cm : 0.6 km (approximately)
Using both conversions:
1 inch = 2.54 cm : 1 mile = 1.6 km
=>
2.54 cm : 1.6 km
1 cm : 1.6/2.54=0.6299 km (approximately), or
1 cm : 0.6 km (approximately)
