If a=2 and c=10 what does b equal ? ( Pythagorean Therom

b =

Step-by-step explanation:

a^2 + b^2 = c^2 is the Pythagorean theorem

if A = 2 and C = 10 then you get

2^2 + b^2 = 10^2

or 4 + b^2 = 100

b^2 = 96

b = square root of 96 or approximately 9.8

$7 + $0.20p = $5 + $0.30p

Step-by-step explanation:

UPS charges $7 for the first pound and $0.20 for each additional pound.

FedEx charges $5 for the first pound and $0.30 for each additional pound.

Let's take the number of  additional pounds that will make UPS and FedEx cost the same to be p.

$7 + $0.20p = $5 + $0.30p

$7 - $5 = $0.30p - $0.20p

$2 = $0.10p

p = = 20 additional pounds
