Answer:
Because if 2 sides are congruent that means 2 sides are the same wich means that each that only one edge can change at a time. I hope this helps.
Step-by-step explanation:
Find how many half lives have passed
seems we are measuring in days
half life formula is as follows
A=final amount
P=initial amount
t=time in a certain units (this time, it's days)
h=time of half life
so
we are given that P=1, A=0.6, t=3
find h
subsitute
take ln of both sides
multiply both sides by h
divide both sides by ln(0.6)
use your calculator
h≈4.07075
so about 4 days is the half life
S10 = -150;
<span> the sum of next 10 terms = S20 - S10 => -550 = S20 + 150 => S20 = -700;
</span>S10 = -150 => 2a1 + 9r = -30;
S20 = -700 => 2a1 + 19r = -70;
Then 10r = -40 => r = -4 , and, 2a1 -36 = -30 => 2a1 = 6 => a1 = 3;
Answer:
Aproximitly 50 soda bottles
Step-by-step explanation:
=
- Subtract the numbers :
- Divide: 149 ÷ 3 ≈ 49. 66667
- Round up because there cant be .66667 of a soda bottle
