Answer:
3.7 < 4.7
Step-by-step explanation:
Find the square root of 3 (1.732 and I rounded to the tenth place) and add 2 then add 1.7 + 3 and 3.7 is less than 4.7
Half life means exactly 1/2 of what's left decays
example
if yo has 16grams
if half life is 1 hour, after 1 hour, 8g is left
after another hour, 4g is left
after another your, 2g is left
etc
so find how many half lifes have elapes
so
the amount left after n halflives when you start with P amount is
A=P(1/2)^n
5hr=60*5=300mins
300/30=10
10 half lifves
P=1500
n=10
A=1500(1/2)^10
A=375/256
A≈1.46484g
about 1.5g left

Step-by-step explanation:
Answer:
115 degrees
Step-by-step explanation:
We know that all the angles of a triangle add up to 180 degrees.
Therefore 7x+10+x+20+2x=180
Combine like terms
10x+30=180
Subtract 30 from both sides (subtraction property of equality)
10x=150
Divide both sides by 10 (division property of equality)
x=15
Now we can plug this into the largest angles equation.
7(15)+10
= 115 Degrees.
