Essentially any like term is a variable with the same letter at the end or the same letter and power.
In this equation, we are given:
- a variable, a letter, and a power
- a variable, and a letter
- a variable
They are all different, so there are 3 different terms in the equation
Best of Luck!
Answer: It will take about 77 years (76.8 years).
Step-by-step explanation: Time is given by the equation: N=No.e^kt. You know that the concentration has to be 15% from the original so N=15 and No=100. To determine k, you have to look at the half-life. k=ln(0.5)/half-life time. For 28 years, k=-0.0247. Replacing it back into the N=No.e^kt equation, the answer will be 76.8 years.
Answer:
28 in.
Step-by-step explanation:
All you have to do is all the length of all the sides: 6+6+8+8=28 in.
