Step-by-step explanation:
1 mole of any substance = 6.022 * 10²³ molecules.
Number of moles of CO2
= (4.5 * 10¹⁶)/(6.022 * 10²³)
= 0.75 * 10^(-7)
= 7.5 * 10^(-8) mol.
Answer:
C. $80
Step-by-step explanation:
A. $70
B. $65
C. $80
D. $75
When he pays $70 monthly
Number of months = $2330 / $70
= 33.3 months
When he pays $65 monthly
Number of months = $2330 / $65
= 35.9 months
When he pays $80 monthly
Number of months = $2330 / $80
= 29.1 months
When he pays $75 monthly
Number of months = $2330 / $75
= 31.1 months
The monthly amounts that will allow Arthur to pay off his balance the fastest is $80 per month
Answer:
74 weeks
Step-by-step explanation:
Given :
Let x = number of weeks
Gallon A:
Capacity = 666
Leak rate = 4 gallons per week
666 - 4x
Gallon B:
Capacity = 888
Leak rate = 7 gallons per week
888 - 7x
666- 4x = 888 - 7x
666 - 888 = - 7x + 4x
-222 = - 3x
x = 222 / 3
x = 74
After 74 weeks
Uhh -1?
