You want to get 6 to equal the total (48) 48/6=8
So 5×8=40
And 6×8=48
So of the 48 tools he sold 40 of them were hammers
Yes, because this is an expression and contains a variable.
Answer:
After 80 years 432 pounds of radioactive element will be remaining.
Step-by-step explanation:
A function models the amount of a radioactive material.
Here x = number of years taken for decay.
If pound and pound, then we have to calculate the time for decay.
Take log on both the sides of the equation
-0.0077x = ln(0.54)
-0.0077x = -0.616186
x =
x = 80.02 years
Therefore, After 80 years 432 pounds of radioactive element will be remaining.
P(sugar cookie)= 8/28=4/14
P(peanut butter cookie)=5/27
