360-290 = 70°

35B) <em>L</em><em> </em>D = ½× 70 = 35°

35C) <em>L</em><em> </em>AEC = ½(100+70)=½×170= 85°

Answer:

x = 10

Step-by-step explanation:

22 - 2x + 4(x - 2) = 34

22 - 2x + 4x - 8 = 34

22 - 8 - 2x + 4x = 34

14 + 2x = 34

Radium-226 has a half life of 1622 years. If you start off with a 200

sweet [91]

Answer:

≈23.6 kg left.

Step-by-step explanation:

For determining this, we can simply use an exponential decay equation representing this scenario:

$y= a(0.5)^{\frac{t}{h} }$

a: the initial amount

t: the amount of time

h: the half life

Now, substitute the numbers into the equation:

$y=200(0.5)^{\frac{5000}{1622} }$

Now, solve this equation:

$y=220(0.5)^{3.08}$

Use a calculator to solve for y:

y= 200(0.118)

y≈23.6 kg left.
