Answer:
Ronnie spent 5 hours working.
Step-by-step explanation:
From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:
c=25+30x, where:
c is the total cost of the job
x is the number of hours
Now, you can replace c with 175 and solve for x:
175=25+30x
175-25=30x
150=30x
x=150/30
x=5
According to this, the answer is that Ronnie spent 5 hours working.
Answer:
Step-by-step explanation:
Start by doing a much simpler problem
One
i^0 = 1
i^1 = i
i^2 = i^2 = - 1
i^3 = i^3 = (-1) * i = -i
i^4 = i^4 = (i)^2 * i^2 = -1 * -1 = 1
So now you are ready to tackle the question you were given.
Two
Every 4th power of i repeats itself. You must get one of the four answers above.
So divide 5689 by 4. What do you get?
1422.25
What does that mean?
It means that you run through the cycle of four 1422 times. What does that mean?
1 * 1 * 1 * 1 * 1 * 1 * 1 * 1 ....................................*1
There are 1422 ones in that expression.
What about the 0.25? What about that?
That means that you have one i left over.
So the answer is i
Three
The simple question defines the pattern which will repeat itself over and over again. By knowing how the simple pattern works you can develop any power of i. For example
i^15622 =
3905.5
0.5 is the same as 2/4
i^2 = -1
i^15622 = - 1
Answer: 8+(x÷3)=−2.

Answer is D hope I helped
- Let the smaller number be x and the bigger number be y.
- Therefore, 3x = 2y
- Therefore, the smaller number = 30 - 18 = 12
