The answer would be (3x+4)(2x-5) because you would factor by grouping.
The answer is 75 liters per 100km. If you divide 340 by 100 you get 3.4 and then divide 255 by 3.4 you get 75.
Answer:
Judy spent 55 minutes exercising
Step-by-step explanation:
Here, we want to know the amount of time Judy spent exercising.
We proceed as follows;
Mary spent 3 hours , sandy spent 50 minutes less than Mary. The amount of time spent by Sandy is thus 2hrs 10 minutes
Judy spent 1hr 15 min less, the amount of time he spent is thus
2hrs 10 minutes - 1 hr 15 min
2 hrs 10 minutes is same as 2(60) + 10 = 120 + 10 = 130 minutes
I hr 15 minutes = 60 + 15 = 75 minutes
The amount of time spent is thus 130 - 75 = 55 minutes
Let's raise i to various powers starting with 0,1,2,3...
i^0 = 1
i^1 = i
i^2 = ( sqrt(-1) )^2 = -1
i^3 = i^2*i = -1*i = -i
i^4 = (i^2)^2 = (-1)^2 = 1
i^5 = i^4*i = 1*i = i
i^6 = i^5*i = i*i = i^2 = -1
We see that the pattern repeats itself after 4 iterations. The four items to memorize are
i^0 = 1
i^1 = i
i^2 = -1
i^3 = -i
It bounces back and forth between 1 and i, alternating in sign as well. This could be one way to memorize the pattern.
To figure out something like i^25, we simply divide the exponent 25 over 4 to get the remainder. In this case, the remainder of 25/4 is 1 since 24/4 = 6, and 25 is one higher than 24.
This means i^25 = i^1 = i
Likewise,
i^5689 = i^1 = i
because 5689/4 = 1422 remainder 1. The quotient doesn't play a role at all so you can ignore it entirely
Answer:
600
Step-by-step explanation:
6000/50=120 groups of 50
120x5=600
