The substance of 256 gm will be decayed into 1 gm in 800 years.
Step-by-step explanation:
Given,
The substance decays 75% in every 600 years.
Amount of substance = 256 gm
To find the the time the substance to decay to 1 gm.
Now,
75% decay in 600 years
1% decays in 600÷75 years
100% decays in ×100 years
= 800 years
Hence,
The substance of 256 gm will be decayed into 1 gm in 800 years.
They are congruent.
So, 4x - 26 = 3x + 4
x=30
Answer:
x=√6^2 + 14^2
Step-by-step explanation:
use Pythagoras theorem
Recall your SOH CAH TOA, or
now, bear in mind that, the opposite side, to an angle, is the side right "in front of it", that is, if you were to put your eye on that angle, "the wall" you'd see on the other end, is the opposite side
the adjacent side, adjacent = next to, is the side that's touching the angle itself
and the hypotenuse, is always the slanted and longest side of all three
for example on 16, tangent of Z
if you put one eye on Z, you'll see on the other end, the side of 30 units
the adjacent side is the one touching Z, or the 40 units side
and you'd do all others, the same way, using those ratios
