When the first quantity is 15, the second quality is 18. This means that the second quality is 3 more than the first quality.
If the first quantity is 10, what is the value of the second quantity?
10 + 3 = 13
Let the first quantity be y
Let the second quantity be x
Since the two quantities vary inversely, therefore, the first, y varies inversely to the second, x:
∴ .................................. (1)
where k is the constant of proportionality.
When the first, y = 15, the value of the second, x = 18
∴ From eqn (1), we have to find k
k = 15 x 18 = 270
Now, the value of the second quantity x, when the first y = 10 is
Making x subject of formular, we have
The value of the second quantity is 27
The value of second quantity is 27
Inverse variation can be represented by the equation xy=k or i.e,
y varies inversely as x , if there is some nonzero constant k such that, xy =k or where x≠0 and y≠0.
Given: Two quantities vary inversely.
Let x be the first quantity and y be the second quantity if they vary inversely.
then, by definition of inverse variation;
Substitute the value of x=15 and y=18 to solve for k;
Multiply both sides by 15 we have;
now, find the second quantity y using same method when x=10.
after substituting the value of x=10 and k=270 in  ;
Therefore, the second quantity value i.e,y = 27
15 = k/18
270 = k
10 = 270 /x
10 x = 270
x = 27
the second number is 27
hope this helps
blue marble is 15 times out of 50 = 15/50 reduces to 3/10
landing on tails is 24 out of 50 = 24/50 reduces to 12/25
to find the probability of both multiply together:
3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250
if you multiplied the numerator and denominator by 10 you get 360/2500.
the answer is 360/2500
answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
