Answer:
Claire borrowed $500 from her father.
Step-by-step explanation:
Interest = $90
p = ?
r = 6% or 0.06
t = 3
Simple interest formula is :

Putting values in formula we get;


p = $500
Hence, Claire borrowed $500 from her father.
Answer:
Her model is 37 times as tall as Ben's.
Step-by-step explanation:
70 11/12 ÷ 5 3/4
851/12 ÷ 23/4
851/12 x 4/23
37/1 x 1/1 = 37 times as tall
Answer:
145
Step-by-step explanation:
steps in attached illustration
#4 = B
Explanation= Because C&A are the same angle measurement, and the 90 angle is along a straight line making the other angle 90, and the triangles share the same side the postulate you can use is AAS because you can prove that the triangles share 2 common angles and 1 common side
#5 = B
Explanation= Because the triangles already have 1 congruent angle, and 1 congruent side the only thing left we can prove is that because the triangles mirror each other, they have congruent opposite angles (may be called vertical angles) as well so they have 2 angles and 1 side in common which tells you to use AAS
