The decay factor is 0.95<span> because this is </span>95%<span> as a decimal. Just think of how much you need to make up 100% and convert to a decimal. I'd be happy to explain more about how this relates to the exponential decay function y = a(1-b)^x, but I don't want to ramble on</span>
Answer: 78 problems
Step-by-step explanation:
Let x = the total number of problems that Joe started with. Joe finished half of his homework questions at school. This means that he finished 1/2 × x = x/2 of the home work at school. What he has left is x - x/2 = x/2.
He completed one-third after practice. This means he completed 1/3 × x = x/3 after practice The number of problems left altogether would be total number of problems - the the sum of the amount he finished at school and the amount he completed after practice. It would be x -(x/2 + x /3) = x - 5x/6 = x/6
If he has 13 to more to finish, that means
x/6 = 13
x = 13×6 = 78 minutes
Step-by-step explanation:
you must have put the problem in incorrectly because it says that it don't recognize the problem?
Answer:
20 degrees
Step-by-step explanation:
Triangles= 180 degrees total
the tangeant line makes 90 degrees
then you add the seventy degrees
180-90-70=20
2y+3y= 5y
5b+6b=11b
5y+11b+8(y+2)
8•2=16. 8•y=8y
5y+11b+16+8y
5y+8y= 13y
Answer: 13y+11b+16
