Answer:
A
Step-by-step explanation:
The root 5's cancel each other out.
4x-2x = 2x
Therefore
2x/3 is the final answer
Answer:
a) 29% b) 22%
Step-by-step explanation:
The quantities must be expressed in the <u>same units</u>.
a) compare 35 minutes to 2 hours. 2 hours is 2 x 60 = 120 minutes.
35/120 = .291667 = 29%
b) compare 650 grams to 3 kilograms. 3 kg = 3 x 1000 = 3000 g.
650/3000 = .21667 = 22%
Step-by-step explanation:
1- 2x(x -4)
2- 3x(2-3x)
3- 4x²(3x-1)
The second bottle containing 3,750 milliliters of water is larger than the other bottle. It contains 250 more milliliters.
Answer:
Step-by-step explanation:
3 sinθ=3 cos 2θ
sin θ=cos 2θ
sinθ=1-2sin² θ
2sin²θ+sin θ-1=0
2sin²θ+2sinθ-sinθ-1=0
2sin θ(sin θ+1)-1(sin θ+1)=0
(sin θ+1)(2 sin θ-1)=0
sin θ=-1=-sin 90=sin (180+90)
θ=270
or sin θ=1/2=sin 30,sin (180-30)
θ=30,150
solution set is {30,150,270}
