Next time, please include the directions for the problem you post. Here it appears that you have given the values of I, P and t two times each.
Unfortunately, I have to guess what you're looking for.
Assuming that I=$26.25 is the interest earned on Principal P=$500, and that t is the length of time over which the Principal earns interest,
I=Prt. With I, P and t given, it's obvious that our job is to find the annual interest rate, r. So, from I=Prt, we get
$26.25 = $500 (r) (1.5 years) Solve this for the interest rate, r.
Express r both as a decimal fraction and as the equivalent percentage.
In the second to last part, there should have been a 4 added to the right side instead of subtracted, making it x=5 and not x=-3
You put it in a little weird in that part too, watch out for that next time. The 4 that should've been in the second to last part looked like it was being multiplied by the x in the last part
X-35+x+83=180
2x+48=180
2x=132
x=66
angles are 31 and 149 degrees
Answer:
15m
Step-by-step explanation:
For every second, the boy walks 1.5 m
So 6 x 1.5 m equals 9 m total
For every second, the girl walks 2m
So 6 x 2 m equals 12 m total
The boy walked North, so it would look like he is walking upward
While the girl walking West looks like she is walking to the left
Finding the distance between them would look like solving a right triangle
We're gonna use the Pythagorean theorem
12² + 9² = distance²
144 + 81 = 225
√225 = 15
