acid of ngredients = acid content of final soln
.65 x + .05(12-x) = .46 (12) solve for x the amount of 65% solution gallons then 5% amount = 12-x gallons.
1/2 hours + 1/3 hours = 1/combined hours
3 /6 + 2/6 = 5/6 = 1/combined hours
combined hours = 6/5 hour = 1 1/6 hour (1 hour 10 minutes)
Distance is same for both
rate x time = distance
kathy rate = Cheryl rate + 2
(c+2) 5.4 = c 9. Solve for c. Cathy speed. Then Kathy speed= c+2
9 people to choose from (Mark is excluded)
9 c n Where n is the number of people on the committee
8 out of 13 ml is compound B
8/13 x 1287 = ........ ml of B needed
btw.....THAT is an enormous number of kcal per day!!!! You sure it isn't just Cal?
5.5 x 105 kcal/person day / 3.7x 106 kcal/bbl =....... bbl /person day x 365 days / year= ......bbl/person-yr
yep.
yeppers.... pi = 3.14159 if you want to simplify it further... and the answer would be in units2 since it is area
a
p = 6a
6a + 2a = 7.20 a = .90 p = 5.40
