kipiarov [429]

Answer:

350 Stamps left

Step-by-step explanation:

First do 5/8*400= 250

Then take 1/5 of it 1/5*250

You end up with 50 so do 250-50= 200 and add the 150 Canadian stamps to get a total of 350 stamps.

-4/5 to the power of 2 times -3/50
Crazy boy [7]
=(-4/5)^2 * -3/50
square -4/5 first; remember -4/5^2 is the same as -4/5 * -4/5

=(-4/5 * -4/5) * -3/50
multiply -4 numerators; multiply 5 denominators

=(-4 * -4)/(5 * 5) * -3/50

=16/25 * -3/50
multiply numerators 16 & -3; multiply denominators 25 & 50

=(16 * -3)/(25 * 50)
= -48/1250

simplify by 2
= -24/625 (or -0.0384)


ANSWER: -24/625 (or -0.0384)

Hope this helps! :)
