kap26 [50]

A geologist in South America discovers a bird skeleton that contains 80% of its original amount of C-14

We use formula N = N_oe^{-kt}

N0= initial amont of C-14 (at time t=0)

N= amount of C-14 at time t

t= time, in years

k= 0.0001

N is 80% of N0 that is N= 0.80N_o

N = N_oe^{-kt}

0.80N_o = N_oe^{-kt}

Divide both sides by N_o

0.8=e^{-0.0001 t}

Take ln on both sides

ln(0.8)=lne^{-0.0001 t}

ln(0.8) = -0.0001t ln(e)

ln(0.8) = -0.0001t

Divide both sides by -0.001

t = 2231.435513

The age of the bird skeleton is 2231 years old

Sam made 30% of goals in his last 6 games. The points his team scored in the games were 112, 89, 95, 77 and 103 points. On avera
iren [92.7K]

Answer:

28.56

Step-by-step explanation:

First we need to calculate the mean average of the numbers

Average = 112+89+95+77+103/5

Average = 476/5

Average = 95.2

If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;

Average of the last six games = 30% of 95.3

Average of the last six games  = 0.3 * 95.2

Average of the last six games = 28.56

Hence the required point average is 28.56

.<br>The curved surface of cylinder is 484 cm^2 and height is 5.5 cm. Find its radius.​
s344n2d4d5 [400]

Answer:

r=14cm

Step-by-step explanation:

Curved Surface area of a cylinder=484cm²

Height=5.5cm

r=?

Curved Surface Area=2πrh

484=2×3.142×r×5.5

484=34.56r

r=484/34.56

r=14cm
