Answer:
I think that I am right. One train is traveling at 75 mph and the other train is traveling at 91 mph
Step-by-step explanation:
Well right off the bat, I can see a good reason why it should boggle.
If (x+y)=6 and (x-y)=2, then (x+y)(x-y) would be 12. It can't be 20.
The first 4 lines on the paper are inconsistent, so the question in the 5th line can't be calculated.
Another possible source of uncertainty (for us, anyway) is the remarkable similarity between the way you write ' Y ' and the way you write ' 4 ' . For example, look at the ' Y⁴ ' (I think ...) in the last line.
Answer:
$1,125 in interest.
Step-by-step explanation:
We need the formula of I = P * i * t where P is the total principle, i is the rate of interest per year, and t is the total time in years.
So we have
P = $7,500
i = 5%
t = 3 years
I = 7500 * 0.05 * 3
I = 1,125 (Interest)
Now we need to find the amount using A = P + I
A = 7,500 + 1,125
A = 8,625
Therefore $8,625 is our total. While our interest is $1,125.
Answer:
84%
Step-by-step explanation:
<u />
25 needs to be equal to 100, so it would need to be multiplied by 4.
So, do the same thing the numerator 21.
84/100 is equal to 84%
