Answer:
if a line is like so it has a positive slope: / . IF a line is like this it has a negative: \
Therefore that leaves out -1/3 and -3
Either A or C is correct
From the y intercept (where the line intercepts the y axis), in this case 2, to the next point on the line (3, 3) it goes up 1 and over 3 to get to that point from the intercept. Therefore the slope is 1/3. (Rise/run)
1/3
Step-by-step explanation:
7a+20b = 28-b
7a = 28-b-20b
7a = 28-21b
a= 28/7 - 21/7 b = 4-3b
Its dimensions are 4 and 9, or you might say this is a 4 by 9 array. We always mention the rows first and then the columns. The multiplication sentence is
4 × 9 = 36

Answer:
Area of the given fan is 763.4 cm²
Step-by-step explanation:
Area of a sector in a circle = 
Here, angle θ = Central angle subtended by the arc
r = Radius of the circle
Since, fan is in the form of a sector of a circle with radius = 27 cm
Measure of the central angle subtended by the arc FN = ∠FAN = 120°
Area of the fan = 
= 
= 243π
= 763.407
≈ 763.4 cm²
Therefore, area of the given fan is 763.4 cm²
18. 12/4 =3, 36/12 =3 the ratio is 3
19. 108/162 =0.667, 72/108= 0.667 the ratio is 0.667 or 2/3
20. 2/3 / 4/3 = 1/2, 1/3 /2/3 = 1/2, the ratio is 1/2
