Answer:

9. x = 45°

10. x = 55°

11. x = 9°

Step-by-step explanation:

$9. \: x + x + 2x = 180 \\ 4x = 180 \\ x = \frac{180}{4} \\ x = 45$

$10. \: x + (x - 2) + 72 = 180 \\ x + x - 2 + 72 = 180 \\ 2x + 70 = 180 \\ 2x = 180 - 70 \\ 2x = 110 \\ x = \frac{110}{2} \\ x = 55 \\$

$11. \: 4x + 3x + 13x = 180 \\ 20x = 180 \\ x = \frac{180}{20} \\ x = 9 \\$

Answer:

$a\frac{c}{8\pi b}$

Step-by-step explanation:

Divide both sides by $8\pi b$

$\frac{8\pi ab}{8\pi b} =\frac{c}{8\pi b}$

Simplify:

$a\frac{c}{8\pi b}$ ; $a\frac{c}{8\pi b}; b\neq 0$

What is the probability of rolling an odd number on one roll of dice

Tresset [83]

Answer: 1/2 or 50%

Step-by-step explanation: To find out what is the probability of rolling an odd number on a dice, we first need to understand what probability is. Probability is the likelihood that an event will happen. We can find the probability of an event using a ratio. Notice that in this problem, we are asked to find the probability of spinning an odd number. This means that the odd numbers will be a favorable outcome.
