Since this is a right triangle, we can just use Pythagorean Theorem to solve for the side SU:
Length of Hypotenuse^2 = Length of First Leg^2 + Length of Second Leg^2
SU^2 = ST^2 + TU^2
SU = sqrt(ST^2 + TU^2)
SU = sqrt(42^2 + 56^2)
SU = sqrt(4900)
SU = 70
Therefore, the answer is is 70 centimeters.
You have to do a system, lets say x are noble fir trees and y are douglas fir trees,
5x+3y=420
12x+9y=1080
if you solve this you get,
x=60 and
y=40
SO Noble fir trees cost $60 and Douglas fir trees cost $40.
It depends on where the sun is but the answer is 22 but my math could be wrong
Answer:
23 cards.
Step-by-step explanation:
After Monday, Esteban has 12 cards.
After Tuesday, Esteban has 12 + 24 = 36 cards.
He gave to his sister x cards.
36 - x = 13
36 = 13 + x
