Answer:
<h2>P = 40.56 ft</h2>
Step-by-step explanation:
We have three sides of a rectangle, and a semicircle.
Three sides of a rectangle: 10ft + 8ft + 10ft = 28ft.
The circumference of a whole circle: C = π(8) = 8π ft.
The semicircle: 8π : 2 = 4π ft
Using π ≈ 3.14 → 4π ≈ (4)(3.14) = 12.56 ft
The perimeter of the figure: P = 28ft + 12.56ft = 40.56ft

Answer:
t = 15825.11 years
Step-by-step explanation:
From the given information:
We can make use of the activity of the sample present after time "t" to determine the age of the sample.
This can be expressed by the formula:
--- (1)
where;
= activity of the sample at time t = 0
= disintegration constant
If we replace the value of into equation (1), we have:
By rearrangement:
t = 15825.11 years
55:86
Step-by-step explanation:
86+55=123 so ratio is from girls to boys
The volume of the gone is about three inches
