If triangle MNO is congruent to triangle PQR, which statement is not true?segment MN ≅ segment QP
^ would this be the untrue statement?

∠N ≅ ∠Q

segment NO ≅ segment QR

∠O ≅ ∠R

Answers

Answer: segment MN ≅ segment QP

Step-by-step explanation:

We know that if two triangles are congruent then their corresponding sides and angles are congruent.

Therefore, If triangle MNO is congruent to triangle PQR.

Then, segment MN ≅ segment PQ not segment QP [by CPCTC]

because PQ is the corresponding to side MN.

∠N ≅ ∠Q [by CPCTC]

segment NO ≅ segment QR [by CPCTC]

∠O ≅ ∠R [by CPCTC]

Therefore, the untrue statement will be:

segment MN ≅ segment QP

the first one is the untrue statement

200 at 6% how much will Rachel have in her account in 10years

Answers

simple interest
I=PRT
I=interst
P=principle (present amount)
R=rate (in decimal)
T=time in years

200=Principal
6%=0.06=R
T=10 years

I=200(0.06)(10)
I=12(10)
I=120

ok so she earns 120
add that
200+120=320

she has $320 after 10 years

Answers

I can't help you, but I can provide an example related to this question.

In the 2009-2010 school year in country A, there were 116,000 foreign students from country B.In the 2009-2010 school year in country A, there were 116,000 foreign students from country B. This number is 22% more than the number of students from country C. How many foreign students were from country C?

If x represents the number of students from country C.

then 122% of x = 116,000

122/100 * x = 116000

Transposing the formula for x;

therefore x = 116000 * 100/122 = 95,082 students

I'm stuck on both of these questions. Any answer will be better than what I got. Please include brief explanation :)
