Explanation:
Consider ...
x/a = b/c . . . . . find x
Multiplying by the denominator under x gives ...
x = ab/c . . . . the value of the unknown.
____
In the case where the unknown is in the denominator, you can invert the ratios and solve as above:
a/x = c/b . . . . . note that x is in the denominator
x/a = b/c . . . . . equivalent equation, solve as above
A = P( 1 + rt)
A/P = 1 + rt
A/P - 1 = rt
t = (( A/P)) - 1)/r
t = (( 5500/1000) - 1)/(6.25/100
t = (5.5 - 1)/0.0625
t = 4.5/0.0625 = 72 years
Answer it will take 72 Years...
Hope it helps!!!!!
The length of an arc subtended by a central angle is proportional to the circle's circumference. If the given central angle has measure 
and the circle has radius 
, then the arc has length 
such that
where is given in radians. Then
If is given in degrees, then
Answer:
Step-by-step explanation:
The triangle is shown in the attachment.
Recall that;
This implies that;
We substitute the values into the ratio to obtain
