Answer:
y = x*(6 feet/1 fathom)
Step-by-step explanation:
We know the relation:
1 fathom = 6 feet.
We can write:
1 = (6 feet/1 fathom)
Now, remember that any number multiplied by 1 does not change.
Then suppose that we have a measure of 3 fathoms, then:
3 fathoms = (3 fathoms)*1
= (3 fathoms)*((6 feet/1 fathom)) = (3 fathoms/1 fathom)*(6feet)
= 3*(6 feet) = 18 feet.
So we changed the units by multiplying the original measure by (6 feet/1 fathom)
Then, if x is the depth of water in fathoms and y is the depth of the water in feet, we can write:
y = x*(6 feet/1 fathom)
The measure of an arc refers to the arc length divided by the radius of the circle. The arc measure equals the corresponding central angle measure, in radians. That's why radians are natural: a central angle of one radian will span an arc exactly one radius long.
<u>Answer with step-by-step explanation:</u>
We are given that Sam invested $48,000 at 6% interest and the rest at 10%. Given that he received $4,000 interest in one year, we are to find how much he invest at each rate.
Assuming the amount invested at 6% interest rate as 
, we can write it as:
![(\frac{6}{100} \times x)+(\frac{10}{100} \times [48000-x])=4000](https://tex.z-dn.net/?f=%28%5Cfrac%7B6%7D%7B100%7D%20%5Ctimes%20x%29%2B%28%5Cfrac%7B10%7D%7B100%7D%20%5Ctimes%20%5B48000-x%5D%29%3D4000)
So the amount invested at 6% = $20,000 and amount invested at 10% = (48000 - 20000) = $28,000

Answer:
-3a-7b-12
Step-by-step explanation:
(5a-4)-(8a+7b+8)
Distribute the minus sign
(5a-4)-8a-7b-8
Combine like terms
5a -8a -7b -4-8
-3a-7b-12
