Answer:
7%
Step-by-step explanation:
30.80%=0.308
0.308/440=0.0007%
0.0007 is the same as 7%
Answer:
1 5/7 glasses
Step-by-step explanation:
4/5 of 6 ounces is 24/5 ounces
24/5 ounces in 2 4/5 hours equals 'x' ounces in 1 hour
(24/5)÷(14/5) = x/1
cross-multiply:
24/5 = 14x/5
70x = 120
x = 12/7 or 1 5/7
1 time for every six rolls
Answer:
A
Step-by-step explanation:
We want to solve the equation:

For the interval [0, 2π).
First, we can move all the terms to one side. Start off by subtracting sin(x) from both sides:

We can factor:

By the Zero Product Property:

Solve for each case:

Use the unit circle to solve:

Hence, our answer is A.
*Please note that we should not simply divide both sides by sin(x) to acquire 2sin(x) = 1. The problem with the operation is that we are dividing by sin(x), yet we do not know what the value of x is. Thus, one or more values of x may result in sin(x) = 0, and we cannot divide by 0. Hence, we are required to subtract and then factor, unless the question specifically states that sin(x) ≠ 0.
