Answer: 40%
Step-by-step explanation:
There are 70 cookies in total.
The gingerbread cookies number 28.
The percentage that are gingerbread will therefore be:
= Number of gingerbread/ Total number of cookies * 100%
= 28 / 70 * 100%
= 40%
You can turn 9/6 into a mixed number by doing it 2 ways:
9/6=1 3/6 or 1 1/2
<span>Or you can simplify it to 3/2 to make it easier to form into a mixed number. 1 1/2
Hope this helped :)</span>
With some simplification,
cos⁻¹(x) - 5 cos⁻¹(x) - π/3 = 2π/3
becomes
-4 cos⁻¹(x) = π
or
cos⁻¹(x) = -π/4
However, the inverse cosine function has a range of 0 ≤ cos⁻¹(x) ≤ π, so there are no solutions to this equation.
80=-8a
We are trying to solve for a. So we need to get a alone. To do that we have to divide each side by -8.
80/-8= -8a/-8
Once you have solved each side you will get the following.
-10=a
