This is hard in mathematical language, but there is only this way to present it. Let us denote by A the consentration of the substance and by A' its rate.
We have that b/A= t+c where c is a constant.
Hence A=b/(c+t)
By differentiating, we get that A'=-b/(C+t)^2
Then, we have that -(A)^2=A'/b
Hence at any point, we have that if we make the concentration 17 times, we have that there is a 17 times bigger , the rate will become bigger by 17*17, hence 289 times faster.
The common ratio is the fifth term divided by the fourth term: -40/-8 = 5.
The seventh term is :
You add all the shirts pants etc together...which is 12+29+49 then you times it by 5 because there are 5 members in the group, this will leave you with the total cost of the bands outfits! you total should be $450 in the end
Answer:
5/6
Step-by-step explanation:
1/2 times by 3 = 3/6
1/3 times by 2 = 2/6
then add these together to get 5/6
Answer:
88 hrs
Step-by-step explanation:
1/3/4 = 7/4hr ; 7/4 = 1.75hr (the number of hours used to travel for 154km)
154/1.75 = 88 (the number of km van travels per hour)
