Answer:
n = 11
General Formulas and Concepts:
- Order of Operations: BPEMDAS
- Equality Properties
- Vertical Angles: Angles that are across from each other and are congruent
Step-by-step explanation:
<u>Step 1: Set up equation</u>
<em>Vertical angles must be congruent.</em>
(6n - 4)° = (5n + 7)°
<u>Step 2: Solve for </u><em><u>n</u></em>
- Subtract 5n on both sides: n - 4 = 7
- Add 4 to both sides: n = 11
Answer:
V = 486
, or approx. 1,526.814
Step-by-step explanation:
V = *r²*(h/3)
plug in the numbers: V = * (9)² * (18/3)
simplify: V = * 81 * 6
simplify: V = 486, or approx. 1,526.814
Answer:
What's the difference between a number track and a number line? A number track is a sequence of numbers, each inside its own square. ... Whereas, a number line is where the numbers are attached to markers on a line. This method of addition / subtraction comes later.
1. Let's check the problem backwards. So let's map A"B"C" to ABC
2. We first need to reflect A"B"C" to A"B"C' with A"B"" as the axis of rotation.
3. Then we shift a few units up (translation) A"B"C' to A'B'C
4. Finally we rotate A'B'C around C to map the triangle onto ABC
going backwards we get the answer: b
<span>b.rotation, then translation, then reflection</span>
