12 - 6 = 6
18 - 12 = 6
24 - 18 = 6
30 - 24 = 6
and there can be many numbers that has same difference as 12-6 .....
Hope it helps !!!
Answer:
8 square units
Step-by-step explanation:
The figure is a trapezoid. The area of it is given by the formula ...
A = (1/2)(b1 +b2)h
where b1 and b2 are the lengths of the parallel bases and h is the distance between them.
Your figure shows the base lengths to be 5 and 3, and their separation to be 2. Filling the numbers in the formula, we have ...
A = (1/2)(5 +3)(2) = (1/2)(8)(2) = 4·2 = 8
The area of the figure is 8 square units.
_____
The right-pointing arrows on the horizontal lines identify those lines as being parallel. The right-angle indicator and the 2 next to the dotted line indicate the perpendicular distance between the parallel lines is 2 units.
Answer: 16.33 feet/s
Explanation:
1) Data:
a) circular motion
b) revolutions: 12 rpm
c) r = 15 feet
d) v = ?
2) Formulae:
angular velocity: ω = number of rpm × 2π / 60 seconds
linear velocity: v = ω × r
3) Solution:
ω = 12 × 2π / 60 s = 0.4π rad / s
v = 0.4π rad / s × 13 feet = 5,2 π feet / s ≈ 5,2 (3.14159) feet / s = 16.33 feet/s.
That is the answer.
Answer:
n
b = ---------
(g+l)
Step-by-step explanation:
We need to isolate b. Starting from (g+l)b=n, we divide both sides by (g+l), obtaining
n
b = ---------
(g+l)
