Answer:
28
Step-by-step explanation:
Let's set the ratio as
7x : 9x
If you add all the states that border an ocean and do not, you will get 48 states (because Alaska and Hawaii are not part of the continental US, as they do not touch the "main" part of the country)
So, we can write this equation.
7x + 9x = 48
Simplify.
16x = 48
Divide both sides by 16.
x = 4
Now, find how many states border an ocean. In our ratio, the number of states that border an ocean was 7x. Substitute x = 4 into 7x
7 * x = 7 * 4 = 28
The number of states that border an ocean is 28.
I hope this helps! Feel free to ask any questions!
can also be written as 2i
where i = √-1
Rationalizing denominator,
Answer:
11/15 or .73333333...
Step-by-step explanation:
heres how i went about it:
think of it as a fraction,
121
------
225
to find the sqyare root of a fraction you would find the square root of each number individually
√121=11
√225=15
then you divide them and get .73333333333333333...
bad at explaining but hope this helped <3
The line CD is the median of thre trapezoid, therefore its measures is shown below:
You must sum the largest base and the shortest base and divide both of them by 2, as following:
CD=(4.5+2.5)/2
CD=7/2
CD=3.5
Therefore, as you can see, the measure of the line CD is 3.5
The answer is: 3.5
