Mika opened a bank account that earns simple interest with an initial deposit of $2,200. she made no other transactions throughout the year. at the end of the year, mika had $2,260.50 in her account. what was the simple interest rate?

 2.75 %

Step-by-step explanation:

Here, the Principal amount or initial amount, P = $ 2200

The Amount by getting simple interest on the amount, A = $ 2260.50

Time, t = 1 year,

Simple interest rate, r ( let)= ?

Since, The amount in Simple interest,

⇒

⇒

⇒

⇒ = 2.75 %

Thus the simple interest rate = 2.75 %

(C) Base angle theorem

Step-by-step explanation:

Given: JKLM is an isosceles trapezoid, KL ∥ JM  

Prove: KM ≅ JL

Proof:

Statements                                                                 Reasons

1. JKLM is an isosceles trapezoid, KL ∥ JM               Given

2. JK ≅ LM                                                definition of isosceles trapezoid

3.  KL ≅ KL                                                          reflexive property

4. ∠JKL ≅ ∠MLK                                          Base angle theorem (base=LK)

5. △JKL ≅ △MLK                                                       SAS rule

6. KM ≅ JL                                                                  CPCTC  

Hence proved.

therefore, option C is correct.
