Answer:
independent=$50
dependent=$35X
Step-by-step explanation:
50 is the independent variable because it doesn't change.
35X is the dependent variable because it does change.
Answer:
volume 1050 
surface area 859 
Step-by-step explanation:
volume is length times width times height (7*25*12)/2
surface area is area of all the sides added together
2(25*12)+(12*7)+ 2(
)
Answer:
7 : 5
Step-by-step explanation:
let the age of the younger be x , then the older is x + 18, thus
x + x + 18 = 108, that is
2x + 18 = 108 ( subtract 18 from both sides )
2x = 90 ( divide both sides by 2 )
x = 45
Thus younger is 45 and older is 45 + 18 = 63
ratio older : younger = 63 : 45 = 7 : 5
Answer:
0.034 L/min
Step-by-step explanation:
The rate of reaction is the volume change (ΔV) divided by the time(t) and divided by the coefficient of the compound in the reaction. The coefficient of O₂ is 1, so:
R = (0.36 - 0.02)/10
R = 0.034 L/min
9.75 * 1.2 = 11.7
24.5 * .8 = 19.6
11.7+19.6= 31.3 minutes
hope this helped :)
