1. If two fathoms are 12 feet deep, we know that one fathom is six feet deep. multiply 6 by 10, and you'll get 60 feet deep.

2. When answering these kinds of questions, I recommend looking at an analog clock. When you count from 10:30 to 3:30, you see that Jessica babysat for five hours. $6.50 multiplied by five is $32.50.

Which division problem does the diagram below best illustrate?
NikAS [45]
I’ve never seen it done that way but I would say it’s 32 / 4 = 8

Collectively, there are 32 squares, separated into groups of 4. When you divide 32 by 4, you’re left with 8 which is reflected by the 8 blue ovals

What is 4log1/2^w(2log1/2^u-3log1/2^v written as a single logarithm?
IrinaK [193]
Given:

4log1/2^w (2log1/2^u-3log1/2^v)

Req'd:

Single logarithm = ?

Sol'n:

First remove the parenthesis,

4 log 1/2 (w) + 2 log 1/2 (u) - 3 log 1/2 (v)

Simplify each term,

Simplify the 4 log 1/2 (w) by moving the constant 4 inside the logarithm;
Simplify the 2 log 1/2 (u) by moving the constant 2 inside the logarithm;
Simplify the -3 log 1/2 (v) by moving the constant -3 inside the logarithm:

 log 1/2 (w^4)  + 2 log 1/2 (u) - 3 log 1/2 (v) 
log 1/2 (w^4) + log 1/2 (u^2) - log 1/2 (v^3)

We have to use the product property of logarithms which is log of b (x) + log of b (y) = log of b (xy):

Thus,

Log of 1/2 (w^4 u^2) - log of 1/2 (v^3) 

then use the quotient property of logarithms which is log of b (x)  - log of b (y) = log of b (x/y)

Therefore, 

log of 1/2 (w^4 u^2 / v^3)

and for the final step and answer, reorder or rearrange w^4 and u^2:

log of 1/2 (u^2 w^4 / v^3)
