Answer:
1101 base 2
Step-by-step explanation:
you first take the larger number up the the lower number down

- when dividing if it's zero you borrow one from the number on the left hand side
- since it's in base 2 the number you borrow would be 2 then u subtract
- I hoped it helped u

Answer:
(the relation you wrote is not correct, there may be something missing, so I will simplify the initial expression)
Here we have the equation:

We can rewrite this as:

Now we can add and subtract cos^2(x)*sin^2(x) to get:

We can complete squares to get:

and we know that:
cos^2(x) + sin^2(x) = 1
then:

This is the closest expression to what you wrote.
We also know that:
sin(x)*cos(x) = (1/2)*sin(2*x)
If we replace that, we get:

Then the simplification is:

10% of 80 = 8
80 - 8 = 72
if they are 10% off, the contact lenses will cost $72
