Answer:

2 grams

Step-by-step explanation:

50 years is 5 half lives as 1 half life is 10 years.

64 divide 2 = 32-1 half life

32 divide 2 =16-2nd half life

16 divide 2 = 8-3rd half life

8 divide 2 = 4-4th half life

4 divide 2 = 2-5th half life

This means we will have 2 grams left of the radioactive substance after 50 years.

In Kite KLMN, find the measure of
Degger [83]

Answer:

M = K =

<h3>101°</h3>

Step-by-step explanation:

M = K, because it's a kite.

  • Kite has 2 angles on the left and right, each with the same size,
  • The kite also has different angles at the other angle points.

(Addition of kite angles result in 360°)

Therefore

360 = 63 + 95 + 2M

2M = 360-63-95

2M = 202

M = 202÷2

M = K = 101°

The size of each angle M and angle K = 101 degrees.
