Question

T varies as the square root of L. if L=81, Then =10.
(direct variation)

Answer 1

Answer:

90

Step-by-step explanation:

L=81

T=K√L

= K√81

=K*9

=10*9 [here, K=10]

T =90

Answer 2

Explanation:

• Given that T varies as the square root of L. If $L=81$.
• We have to find the value of T.

Step

Step 1 of 1:

We know that if T varies as the square root of L.

Then it can be written as

$T=k\sqrt{L}$  ,  where $k=10$

So,

$T=10\times \sqrt{81}\\T=10\times 9\\T=90$

Final Answer :

The value of $T$ is $90$
