Answer:
V= 105cm^3
Step-by-step explanation:
V=volume
(1/3)V+40=(5/7)V
(5/7)V-(1/3)V=40
(15/21)V-(7/21)V=40
(8/21)V=40
(21/8)(8/21)V=(21/8)(40
V=21*5
V=105 cm3
(1/3)(105)=35, 35+40=75, 75/105=15/21=5/7
The GCF would be 14a, because 14a x 1 = 14a, and 14a x 2b = 28ab.
Answer:
D
Step-by-step explanation:
70% as a fraction is 70/100
The sum of all angles in a regular octagon is 1080 degrees. Because all sides are the same (regular octagon), all of the eight angles are the same too, so we simply divide 1080 by 8 and that is the solution.
1080/8 = 135
Magnitude = sqrt (4^2 + 4^2 + 1^2) = sqrt 33 Answer
