The reason why it is equal is because when you divide you are really subtracting so 10^15-10^4 so 15-4 equals 11
Answer:
AC = 146.2
Step-by-step explanation:
We are assuming that BC is tangent to circle A and that AB is perpendicular to BC. This problem involves the use of the Pythagorean theorem.
a = t
b = 25
c = 144
a² = b² + c²
a² = 25² + 144²
a = √(25² + 144²)
a = √625+20736)
a = √21361
a = 146.154
The length of AC is 146.2 units.
Answer:
Step-by-step explanation:
2nd one
You would do 8/9 - 3/5
convert everything to whatever/45
so 40/45 - 27/45
the answer is 13/45 of an hour.

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
<em>a</em> = 12
<em>b</em> = 5
<em>c</em> = x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [PT]: 12² + 5² = x²
- Evaluate exponents: 144 + 25 = x²
- Add: 169 = x²
- [Equality] Square root both sides: ±13 = x
- Rewrite: x = ±13
Since we are dealing with positive numbers, we can disregard the negative root.
∴ x = 13
