Answer:

I believe you need to know the side of JK and MN if I'm not mistaken.

Answer:

Answer: JK ≅ MN 

WORKINGS

Given,

Angle J is congruent to Angle M (∠J ≅ ∠M)

Side JL is congruent to side MR (JL ≅ MR)

Triangle JKL is congruent to Triangle MNR ΔJKL ≅ △MNR

We are to give the additional information to show that triangle JKL is congruent to triangle MNR by SAS Postulate; SAS Postulate states that if two sides of one triangle and the angle formed by them are congruent to the corresponding parts of another triangle, then the two triangles are congruent.

Angle J is formed by sides JL and JK

Angle M is formed by sides MR and MN

Therefore, If the two triangles are congruent,

Angle J is congruent to Angle M

and Side JL is congruent to side MR

Then, Side JK is congruent to side MN (JK ≅ MN).

The additional information is needed to show ΔJKL ≅ △MNR by SAS is JK ≅ MN

A 1200 kg car rolling on a horizontal surface has speed v = 50 km/h when it strikes a horizontal coiled spring and is brought to
tangare [24]
When the car is moving, it has Kinetic Energy. As soon as the car entercount with the spring, its Kinetic Energy will transfer to Elastic Potential Energy. 

<span>KE = EPE </span>
<span>1/2mv^2 = 1/2kx^2 </span>

<span>change the speed into m/s </span>
<span>50 km/hr = 13.9 m/s </span>

<span>1/2(1200)(13.9)^2 = 1/2k(2.2)^2 </span>

<span>now you do the math to solve for k.
k= 115926/2.42
K= 47903.30</span>

Parker was able to pay for 44% of his college tuition with his scholarship.
WITCHER [35]
The total cost is $17,955.

Let x be the total amount of his tuition.  He paid for 44% of it, or 0.44, with his scholarship. This leaves 100%-44% = 56% = 0.56 of it to be taken care of with loans.  We know he took out 10054.52 in loans:

0.56x = 10054.52

Divide both sides by 0.56:
0.56x/0.56 = 10054.52/0.56
x = 17954.50 ≈ 17955

What % is 9 of 27? I am really, really, really confused about this question
ddd [48]

To find the percent, divide 9 by 27 to get a decimal, then multiply the decimal by 100 to get the percent:

9 / 27 = 0.333

0.333 x 100 = 33.3%
