Answer:
Multiplication and Division unless there are parentheses
Step-by-step explanation:
<span>here is some introduction.
A common
language is needed in order to communicate mathematical ideas clearly and
efficiently. Exponential notation is one example. It was
developed to write repeated multiplication more efficiently. For example, growth
occurs in living organisms by the division of cells. One type of cell divides 2
times in an hour. So in 12 hours, the cell will divide 2 • 2 • 2 • 2 • 2 • 2 • 2
• 2 • 2 • 2 • 2 • 2 times. This can be written more efficiently as
212.</span>
Answer:
11. s = 14
12. k = 24
Step-by-step explanation:
There are two "special" right triangles that show up in trig and geometry problems.
The isosceles right triangle has angles of 45°-45°-90°, and side length ratios 1 : 1 : √2.
The half-equilateral triangle has angles of 30°-60°-90°, and side length ratios 1 : √3 : 2.
You will do yourself a favor if you remember and learn to recognize these triangles.
__
<h3>11.)</h3>
The hypotenuse of the isosceles right triangle is 14√2. This tells you the basic ratio has been multiplied by 14. The side length is ...
s = 14
__
<h3>12.)</h3>
The half-equilateral triangle has middle-length side 12√3. This means the basic ratio has been multiplied by 12. The triangle short side is 12, and the long side is twice that:
k = 24
