Answer:5/3
Step-by-step explanation:
choose two coordinates (40,0) and (70,50) then use y2-y1/x2-x1. when you plug the numbers in 50-0/70-40, subtract 50/30, and simplify, you get 5/3
Answer:

Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its corresponding sides is equal and the corresponding angles are congruent
In this problem Triangles PQT and RQS are similar by AA Similarity Theorem (The three angles are congruent)
therefore

Answer:
Just about 3.6
Step-by-step explanation:
a² + b² = c²
√(a² + b²) = c
√(2² + 3²) = c
√(4 + 9) = c
√(13) = c
3.605551275 = c
c ≈ 3.6
Answer:
She is actually paying a rate of 7.36% of interest.
