1. Given the triangle below, answer the following questions
bogdanovich [222]

Answer:

x=81

y=99

z= 129

Step-by-step explanation:

the 3 angles of a triangle add to 180 degrees

51 + 48 + x = 180

99 + x = 180

subtract 99 from each side

99 + x -99 = 180 -99

x = 81


x+y = 180  they make a straight line

81+ y = 180

subtract 81 from each side

y = 180-81

y = 99


z+ 51 = 180  they make a straight line

subtract 51 from each side

z+51-51 = 180 -51

z = 129

How much of a radioactive kind of niobium will be left after 105 days if you start with 3,920 grams and the half-life is 35 days
MariettaO [177]

Answer:

"490 grams" would be the correct solution.

Step-by-step explanation:

The given values are:

Half time,

T = 35 days

Total time,

t = 105 days

As we know,

⇒ A=A_o(\frac{1}{2} )^{\frac{t}{T} }

On substituting the values, we get

⇒     =3920\times (\frac{1}{2})^{\frac{105}{35} }

⇒     =3920\times (0.5)^3

⇒     =3920\times 0.125

⇒     =490 \ grams
