Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining Bismuth-210 transforms i

Luden [163]

Answer:

Approximately 76.5 mg.

Step-by-step explanation:

Given,

The initial quantity of the Bismuth-210, P = 233 mg,

Also, the rate of decay per day, r = 13 %

Thus, the quantity of the Bismuth-210 after 8 days would be,

$A=P(1-\frac{r}{100})^8$

$=233(1-\frac{13}{100})^8$

$=233(1-0.13)^8$

$=233(0.87)^8$

$=76.4733194697$

$\approx 76.5\text{ mg}$

How to find the circumference of a circle

Alborosie

Answer:

Step-by-step explanation:

The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c).

circle diameter radius

A line that is drawn straight through the midpoint of a circle and that has its end points on the circle border is called the diameter (d)

Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).

The circumference of a circle is found using this formula:

C=π⋅dorC=2π⋅r

a farmer leans a 12-ft ladder against a barn. The base of the ladder is 3 ft from the barn. To the nearest tenth, how high on th

stiks02 [169]

Answer:

11.6 ft

Step-by-step explanation:

I attached a diagram for you to easily visualize this problem.

To solve this problem, you would use the pythagorean theorem. The 12-ft ladder is the hypotenuse and the 3 ft from the barn is one of the side legs. You want to find the length of the "other side leg", or the height of the barn.

Substitute 3, 12, and x into the pythagorean theorem like so.

a^2 + b^2 = c^2

3^2 + x^2 = 12^2

Evaluate the exponents.

9 + x^2 = 144

Subtract 9 from both sides.

x^2 = 135

Square root both sides.

x = 11.618

Round this to the nearest tenth: 11.6 feet.
