Answer:
20.
Step-by-step explanation:
That would be 2 1/2 divided by 1/8
= 5/2 / 1/8
= 5/2 * 8
= 40/2
= 20.
Answer:
6; 1, 2, 6
12; 1, 2, 3, 4, 6, 12
18; 1, 2, 3, 6, 9, 18
Step-by-step explanation:
Sorry love i’m so sure but harry might know....?
3x - 2y = 7
-2y = -3x + 7
y = 3/2x - 7/2....slope of this line is 3/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2/3 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2/3
(-3,-2).....x = -3 and y = -2
now we sub and find b, the y int
-2 = -2/3(-3) = b
-2 = 2 + b
-2 - 2 = b
-4 = b
so ur perpendicular equation is : y = -2/3x - 4 <==
Angle = 68⁰ is an inscribed angles, this angle equal 68⁰,
so it intersect arc = 2*68⁰= 136⁰.
Arc of the whole circle (circumference) =360⁰,and it also =b+104+136.
b+104+136 =360
b=360-(104+136) = 120⁰
Answer A. b=120⁰.
