Hello from MrBillDoesMath!
Answer:
.08%
Discussion:
Let the percent be denoted "p". Then
2000 * p% = 160 => ( as p% = p/100)
2000* p/100 = 160 =>
20p = 160 =>
p = 8 or .08%

Answer: C
Step-by-step explanation:
Since y = 0 at x=3pi/2, we know that this is a cosine graph.
So to determine if its -cos or cosine, we can test the pt (0, 1).
Since cos(0)=1 whereas -cos(0)=-1, the answer is y=cos(x).
Answer:
1/10
Step-by-step explanation:
If she painted 1/20 of a fence in 1/2 hour she can paint another 1/20 of the fence in another 1/2 hour.
1/20 + 1/20 = 2/20 = 1/10
Answer:
x > -35
Step-by-step explanation:
When Janet got rid of the 4, she added it to -3 instead of subtracting 4.
So, the next step should look like this:
> -7
Then, multiply both sides by 5.
x > -35
This is the correct way of solving for x in this inequality.
