Answer:
540°
Step-by-step explanation:
inter angle vertex = 135°
135 + 135 + 135 + 135 = 540°
Answer:
(y-18%) + (y+8%)
Step-by-step explanation:
Answer:
$950
Step-by-step explanation:
$950+$75 = $1,025
Therefore, the dryer is $950
Hope this helped! :)
Exponential decay formula is :
Where a≠0, b≠1 , b represent growth or decay factor (or rate) and x is any real number.
But if a radioactive isotope decays in half every year which means the decay factor or decay rate is 50% or 
.
So, the formula for half decay will be:
Where represent c) The rate of isotope decreases.
Her equation doesn't fit the word problem! It says several 2 pounds books but she put it as if there was one. She should have wrote the equation like this:
3 + 2x = 20 (where x represents the unknown amount of boxes)
and than you can just solve for x to find how many books there are
3 + 2x = 20
2x = 20
x = 10
So there are 10 books!
I hope that helps! Let me know if you have any questions :3
