Answer:
a = 9
Step-by-step explanation:
you can simplify the proportion to:
![\frac{a}{24} =\frac{3}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%7D%7B24%7D%20%3D%5Cfrac%7B3%7D%7B8%7D)
use cross- multiplication
8a = 72
a = 9
Last month, my house used 1,740 kilowatt-hours of electrical energy,
and the part of my bill that charged for the electricity was $226.20 .
For the same month, my brother in Boston used 1,175 kilowatt-hours
of energy, and the energy part of HIS bill was $199.75 .
Which of us gets the better deal on his electrical energy ?
Answer:
11
Step-by-step explanation:
The middle of the three is their average, their sum divided by 3:
middle = 27/3 = 9
Then the largest is 2 more. It is 11.
A) You just fill in 0 for w in the problem and anything raised to the power of 0 is 1, so 230(1) is 230, and that is the old factory and at 0 for the new it is at 190. Subtract then explain why you did what you did.
B) I believe what they are asking for you to do, is you can take each week from the new factory and subtract it and find the equation for the new factory, you already know the growth rate for the old factory= 230(1.1)^w.
C) You take your old factory's equation and plug in numbers until one of them is greater at the new factory. Here it is the 5th week.
