Answer:
B) 131°
Step-by-step explanation:
-4a + 139 = 4a + 123 because they are vertical angles
-4a + 139 = 4a + 123
reduce:
8a = 16
a = 2
4(2) + 123 = 131°
Answer:
Slope of line =
Step-by-step explanation:
We have given two points,
(-4 ,-8) and ( - 18 , -10)
We need to find the slope of line passing through these two points.
i.e slope of line =
Here y₂ = -10 , y₁ = -8 , x₂ = -18 and x₁ = -4
Hence,
slope of line = =
Slope of line =
Answer:
450,000
Step-by-step explanation:
The first digit has 9 choices
Digits 2 through 5 each have 10 choices
Digit 6 has 5 choices.
9 * 10 * 10 * 10 * 10 * 5 = 450,000
First, turn 70% into a decimal by dividing 70 by 100.
70% ⇒ 0.70
Multiply 120 by 0.70.
120 × 0.70 = 84
Now we know that 84 students are involved in extracurricular activities. Subtract 84 from 120 to find the amount of students who are <em>not</em> involved in extracurricular activities.
120 - 84 = 36
