Rachel wants to buy a shirt regularly priced at $32. It is on sale for 40% off. Rachel estimates that she will save 2/5 of $30 o
1 answer:
Okay, so first you know that the shirt was priced at $32.
It's on sale for 40%.
40% =
Now we can make a proportion, so set the values in a fraction.
We put 32 on the bottom since it's the total amount.
Divide 100 by 32, so 100÷32=3.2
Now divide the numerator (40) by 3.2, so 40÷3.2=12.5
That means the new cost of the shirt is $12.50 so the new amount will be more than 12 dollars.
Hope that helped :)

Answer:
Step-by-step explanation:
<em>Given:</em>
Mn is diameter of circle having centre O
and BD = OD,
<em><u>To prove that:</u></em>
<u></u>
<em>Solution:</em>
Join the points O and B and draw OB,
On joining the line,
in ∆OCD and ∆OBD,
OC =OB → (Radius of same circle)
BD =CD → (from given)
OD =OD → (Common side in both the triangles)
Hence ∆OCD and ∆OBD are congruent from SSS property.
so we can say that,
Consider above prove as statement A
Corresponding angles of congruent traingle.
in ∆ OAB,
OA = OB (radius of same circle)
hence ∆OAB is an isosceles traingle.
We know that opposite angle of isosceles traingle are always equal. hence,
Consider above prove as statement B
From Statement A & B we can say that
