100+25*12=
100+300=
400
400-320=80
I=PRT
I=80
P=principal=320
T=1 year
R=?
80=320*1*?
80=320?
divide both sides by 320
0.25=?
that is 25%
answer is 25%
Here’s the correct answer and how I got it :)
Answer:
The length of the shorter base of the little trapezoid trail is 1 mi.
Step-by-step explanation:
Let the shorter base of the large trapezoid is S and the larger base of the large trapezoid is L.
Similarly, assume that the shorter base of the small trapezoid is s and the larger base of the small trapezoid is l.
Since, the trapezoids are similar, so
Now, given that S = 2 mi, L = 8 mi and l = 4 mi and we have to find s.
So, mi. (Answer)
A reflection would result in the points (7,-7)
C = (5n + 40)/9
Multiply by 9 on both sides
9C = 5n + 40
Subtract 40 from both sides
9c - 40 = 5n
Divide both sides by 5
9c/5 - 40/5 = n
n = (9/5)c - 8
