Answer:
Its 14
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation:
the formula of common ratio is given as

a1= 27 ,a2=9
r= 9/27
r= 1/3
The slope is 2. The y-intercept is 4.
Explanation:
The line constantly goes up to units for every unit that it goes to the right. The y intercept is 4 because it is 4 on the y-axis when x is 0.
Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180
x = 180° - (90 + 35)° = 180° - 125° = 55°
----------------------------------------------------------
Since the triangle is right use the cosine ratio to solve for b
cos35° =
= 
Multiply both sides by 20
20 × cos35° = b, hence
b = 16.38 ( to 2 dec. places )
