To find out what a percentage written as a fraction would look like, you first need to convert it into a decimal.
To convert a percentage to a decimal, you either need to divide the percentage by 100, or (my personal shortcut) just move the decimal point over two places to the left.
250% = 2.5
The decimal .5 is equivalent to 1/2, since 50 is half of 100.
250% written as a fraction (well, a mixed number, really) is 2 1/2.
Hope that helped =)
<u>Answer:</u>
t = 6.3 days
<u>Step-by-step explanation:</u>
The amount of initial mass is irrelevant when finding the half-life since the remaining mass is always 1/2 of the initial mass.
Taking 
on both the sides to get:
t = 6.3 days

Answer: w=12, y=6√3
Step-by-step explanation:
Looking at the figure, we can split the triangle into 2 separate triangles. One on the left and one on the left. The triangle on the right is a 30-60-90 triangle. For this triangle, the hypotenuse is 2x in length. This is directly opposite of the right angle. The leg opposite to 30° is x in length. The leg opposite 60° is x√3 in length. Once you know the length of one side, you can plug in x to find the length of the other legs.
In this case, w and y are located on the same 30-60-90 triangle. Normally we would focus on that triangle to find our values, but in this instance, we don't have any values. We have to use the left triangle to find the leg that both triangles share.
The left triangle is a 45-45-90 triangle. For this triangle, the legs opposite of 45° is x in length. The hypotenuse is x√2. Since we know the hypotenuse, we can use it to find x.
x√2=8
x=8/√2
x=5.7 or 6 [Let's use 6 so that it is easier to work with a whole number]
Now that we know x, we can find w and y. Going back to the right triangle, we know the hypotenuse is 2x. We plug in 6 to find the length.
w=2x
w=2(6)
w=12
We know the leg opposite of 60° is x√3. We can plug in x.
y=6√3
