Answer:
~84.5 pages
Step-by-step explanation:
Why?
Copy machine prints 169 pages per 2 minutes. In order to solve for 1 minute, you must half the total pages printed in 2 minutes to find the value printed in 1 minute (since 1/2 of 2 minutes is 1 minute)
169/2 = ~84.5 pages
Sanity check:
84.5 pages per 1 minute
84.5 x 2 = 169 pages per 2 minutes
Answer:
28.45
Step-by-step explanation:
33.04-1.75=31.29
31.29/1.10=28.45
Answer: It shall take 8 days
Step-by-step explanation: Because the 4 fruits took 4 days so should the 8 fruits take 8 days
Answer:
Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
Step-by-step explanation:
Let X=set of all odd numbers
that is ![X={\{1,3,5,7...}\}](https://tex.z-dn.net/?f=X%3D%7B%5C%7B1%2C3%2C5%2C7...%7D%5C%7D)
Let Y=set of all even numbers
that is ![Y={\{2,4,6,8...}\}](https://tex.z-dn.net/?f=Y%3D%7B%5C%7B2%2C4%2C6%2C8...%7D%5C%7D)
Verify that 2(n+1) represents an even number where n is an odd number:
Put n=1 in 2(n+1) we get
2(1+1)=2(2)=4
Put n=3 in 2(n+1) we get
2(3+1)=2(4)=8
Put n=5 in 2(n+1) we get
2(5+1)=2(6)=12
and so on.
From above results we get 2(n+1) represents an even number and is belongs to the set Y when n is an odd number.
Therefore Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
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.
