Answer:
965.11
Step-by-step explanation:
- take 27.2 divide it by 2 then use the formula v= 3.14 r to the power of 2 then times it by h.
From Plato
30e-0.12t less than or equal to M
40e-0.18t less than or equal to M
Step-by-step explanation:
It is given that compound A decays at a rate of 12% per week, and compound B decays at a rate of 18% per week. Since the rates represent decay, the r-value is negative. A decay rate of 12% is represented by an r-value of -0.12, and a decay rate of 18% is represented by an r-value of -0.18.
The initial amount of compound A is 30 grams and the initial amount of compound B is 40 grams. Substitute the initial amounts of each compound and their respective decay rates into the system of inequalities.
The following system of inequalities can be used to determine when the remaining mass of the two compounds, M, will be the same, after t weeks.
Story: Maria is hosting a birthday party for her friend. she handed out 212 balloons for each kid to hold but there was 10 left. X shoes the total amount of balloons.
solving the equation:
x+212=10
-212 +212
x=222
Step-by-step explanation:
first of all friend you need to post and questions
then only anyone can find the value of x.....
hope you might understood...
