Jlenok [28]

Answer:94%

Step-by-step explanation:

Half life of a radioactive element is the time taken for half it's mass to disintegrate away.it means after attaining half life,what will be left is 100-50=50%.

Let the 100% mass of C-14,be x

Then 5730years=1/2 of X

Then 660 years=y of X

Where Y is the fraction of C-14 that has disintegrate as at 1988.

5730/660=1/2X/yX

5730/660=1/2/y

Cross multiplying

5730×y=660×1/2

5730y=330

Y=330/5730=0.05759

In %,5.76%

Amount of C-14 left is

100-5.76=94.24=94% as at 1988.

Find angle ADB of the equation

Aloiza [94]

Answer:

$m\angle ADB = 59\°$ .

Step-by-step explanation:

Given:

$\angle BDC = 31\°$

We need to find $\angle ADB$ .

Solution:

Now we can see that given figure is a rectangle with diagonals drawn in it.

So by properties of rectangle which states that;

"All angles of a rectangle are 90°."

So we can say that;

$\angle A = \angle B = \angle C = \angle D = 90\°$

But

$\angle D = \angle BDC + \angle ADB$

Substituting the values we get;

$31\°+\angle ADB = 90\°$

Subtracting both side by by 31 we get;

$31\°+\angle ADB -31\°= 90\°-31\°\\\\m\angle ADB = 59\°$

Hence $m\angle ADB = 59\°$ .

3(n - 1) < 21<br> Does anyone know the answer and solution?

Likurg_2 [28]

Answer:

$n < 8$

Step-by-step explanation:

$3n - 3 < 21 \\ 3n - 3 + 3 < 21 + 3 \\ 3n = 24 \\ \frac{3n}{3} < \frac{24}{3} \\ n < 8$
