Answer:
-14
Step-by-step explanation:
Let x = minimum electric rate (Cents/kWh)
Total months in 12 years is 12*12 = 144 m
1st freezer
Total cost over 12 years is
623.95 (cost) + (90 kWh/m)*(144 m)(x/100 $/kWh)
= 623.95 + 129.6x
2nd freezer
Total cost over 12 years is
500 + 100*144*(x/100)
= 500 + 144x
For the 1st freezer to cost less over 12 years,
623.95 + 129.6x < 500 + 144x
123.95 < 14.4x
8.61 < x
Answer: The minimum rate is 8.61 cents per kWh
Linear equation of plant height is h = (1/2)w + 3
Given:
Height of experimental plant = 3cm
Average growth = 0.5 cm per week
Find:
Linear equation of plant height
Computation:
Given;
h = Plant height
w = number of weeks
So,
Plant height = Height of experimental plant + (Average growth)(number of weeks)
h = 3 + (0.5)(w)
h = (1/2)w + 3

So the division equation would be 2 divided by 3/4 which is 2 and 2/3
and the multiplication problem would be 3/4 times 2 and 2/3 which would get you 2
Hope this helped
Lemme know if I was right :)
