Question

.

Answer 1

you can use the fact
(L1 / L2 ) ^2 = A1 / A2

Answer 2

( 16/ 20 ) ^2 = 26 / A2

Answer 3

lets call A2 just x

Answer 4

ok

Answer 5

so solve that equation

Answer 6

( 16/ 20 ) ^2 = 26 / x

16^2 / 20^2 = 26 / x

x *16^2 = 26 * 20^2

x = 26 *20^2 / 16^2

Answer 7

I'm getting 0.64 for some reason for the 16/20^2... I don't know

Answer 8

yes that is correct

Answer 9

.64 = 26 / x

Answer 10

now solve for x

Answer 11

Sorry I'm trying to understand this 26 * 400 / 256?

Answer 12

yes

Answer 13

40.625 so round to 41?

Answer 14

i think so

Answer 15

Okay thank you :)

Answer 16

it says 'which is the best approximation' , so i assume there are multiple choices given

Answer 17

yeah the options are 41, 49, 25, and 33 so I'm assuming 41 since it's closest.
