Answer:
21
Step-by-step explanation:
The contiguous U.S. consist of all states beside Alaska and Hawaii; therefore, there are 48 contiguous U.S. states. However, the ratio given to us only consists of 16 states [7 + 9 = 16]. If we need to expand the ratio, we multiply 16 by 3 to get 48. Thus, we also multiply each of the terms by 3, and the ratio becomes 21:27. Therefore, the number of contiguous U.S. states that border an ocean is 21.
In this question, you know that the machine packs
of a box every
of a minute. Since it is constant, you simply have to double the half a minute to a full minute and then also double the rate to get
boxes packed per minute. And
is equal to
The left side of the equation subtracts x from 2x.
That means 1x, or just simply x, is left on the left side.
We now have this: x = 6
So, x is 6. Hope this helps!
Answer:7043.82
It would be 4200 x 1.09 which is the interest to the power of 6 for the number of years which would then give you 4200 x 1.09^6. This will then give the answer of 7043.82
