This is quite simple once you understand.
Since 100 is a round number all you must do is move the 0.05 up 2 zeros.
You get the zeros from the hundreds btw.
0.05 x 100 = 5
So the answer is £5
Answer: the circles radius is 2
The equation for circumference of a circle is 2*pi*r
And the equation for the area of a circle is pi*r^2
The only way both of these equations can be true is if 2r(pi)=(pi)r^2
Or
2r=r^2
And when is the square of a number equal to two times the number? When the number is 2
So the radius must be 2
Answer:
It equals
Step-by-step explanation:
P=2L+2W
1. Subtract 2L from both sides
P-2L=2W
2.Divide both sides by 2 to isolate "W"
P-2L/2=W
3.Flip the equation
W=P-2L/2
So solution is
W=P-2L/2
Answer:
Step-by-step explanation:
9x + 8 = 7.5x + 17
1.5x = 9
x = 6 hours
