Answer:
Step-by-step explanation:
1. no-has decimal
2. yes, simplifies to -2
3. yes
4. yes
5. no-2.1
5:$2.50
9:?
divide 5 by both sides cause you wanna see how much is 1 liter so you can multiply that with 9.
5 divided by 5 is 1.
$2.50 divided by 5 is $0.50
1:$0.50
each liter costs $0.50
Multiply $0.50 with 9 and that is $4.50
the answer is $4.50
X/4 = 8
multiply both sides by 4 to get the value of x
x=32
Using Sine.
Sine = Opposite / Hypotenuse
sin 60° = a / (6√3) But sin60° = √3/2
√3/2 = a/(6√3)
Cross multiply
2*a = 6√3 * √3
2a = 6 * √(3*3)
2a = 6*3
a = 6*3/2
a = 3*3 = 9
Option E.
Hope this helps.
