By the converse of the Pythagorean Theorem, if 8.6 ^2 = 8.1 ^2 + 2.6 ^2 , then the triangle is right. 73.96 is not equal to 72.37 so the triangle is not a right triangle.
8.6^2 is greater than (8.1^2 + 2.6^2) which means that the triangle is obtuse.
The obtuse angle is opposite the 8.6 side.
After 1 hour, 360 g decays to 180 g.
After another hour (total 2 hours), 180 g decays to 90 g.
After another hour (total 3), 90 g decays to 45 g.
After one more (total 4), 45 g decays to 22.5 g.
More quickly, with a half-life of 1 hour, the 360 g of starting material decays to
(360 g) / 2⁴ = 22.5 g
In general, if the half-life is 1 hour, then after <em>n</em> hours, an initial amount <em>A</em> of this substance decays according to
<em>A</em> / 2<em>ⁿ</em>
The rotational symmetry has more than one order of rotational symmetry the objects can fit itself within 360 degrees.
Answer:
80 feet.
Step-by-step explanation:
Given:
The length of a rectangular garden is 10 yards and its width is 10 feet.
To find:
Perimeter of the garden in feet ?
Solution:
Length = 10 yards
1 yard = 3 feet
10 yards = 3
10 = 30 feet
Breadth = 10 feet
Now, as we know:


Hence, the perimeter of the garden is 80 feet.
