Hello!

The Correct Answer are:

1. C. 31,536,000 seconds

2. C. 7,700,000

3. 90,000 meters

4. A. 1,260 and 151,200

5. 67 feet

6. B and D

7. 15 x 24 = 360 rings and in another case we have 12 rows and each has 18 rings so in total we have : 12 * 18 = 216 so jewelry store has (360 - 216) rings more than other case so jewelry store has 144 rings more than other case.

8. 23 because 195 + 127 = 322 322/14 = 23

9. B and C

10. We know that 1 hundred= 100= 1*10^2. Therefore, 6,000 hundreds is equal to:
6,000*(1*10^2)= 600,000

Because 600,000 ≠ 6,000,000, Carlos is wrong.

Hope this All Helps! Took me Time!
Have A Wonderful Day! :)

In JKL, mJ = 90, mK = 30, and mL = 60. Which of the following statements about JKL are true?

kumpel [21]

The correct answers are:

KL = 2*JL; JK = (√3)JL; and JK = ((√3)/2)KL

Explanation:

This is a 30-60-90 right triangle. This type of triangle has a special relationship among the sides. Let the smallest side, across from the 30° angle, be t. This means JL = t.

The hypotenuse of the triangle is two times the length of the smallest side; this means that KL = 2t, which means that KL = 2*JL.

The side of the triangle opposite the 60° angle will be the "medium sized" side; it is equal to √3 times the smallest side, or √3t; this gives us that JK = √3t = (√3)JL.

Comparing JK to KL, we have

$\frac{t\sqrt{3}}{2t}$
