So, let's start off with what you know. 
You know that <span>the perimiter of the triangle is 42 yards.
You know that the first side is 5 yards less than the second.
You know that the third side is 2 yards less than the first.
So, we can make the second side x.
We come up with something like this : 

Second Side : x
First Side : x-5
Third Side : x-7

Now we make an equation.

x+x+x-5-7 = 42
3x-12 = 42
    +12    +12
3x      =  54
     3x = 54
       x = 18
So the second side is 18 yards.
Then we can find the First side.
First side is 13 yards.
Then the third side.
The Third side is 11 yards.
So the lengths are : 

First Side : 13 Yards
Second Side : 18 Yards
Third Side : 11 Yards.

I hope I was able to help!</span>

What is log15 2^3 rewritten using the power property?
OlgaM077 [116]

ANSWER

log_{15}( {2}^{3} )  = 3 \: log_{15}( {2} )

EXPLANATION

According to the power property of logarithms:

log_{x}( {y}^{n} )  = n \: log_{x}( {y} )

The given logarithm is

log_{15}( {2}^{3} )

When we apply the power property to this logarithm, we get,

log_{15}( {2}^{3} )  = 3 \: log_{15}( {2} )

A study has shown that the daily amount of milk produced by a dairy cow is
8090 [49]

Answer:

A

Step-by-step explanation:

this is more of a mind game.  Lots of words to throw you off.  Daily a cow produces a mean of 6.2 gallons (average of 6.2 gallons, meaning they already found the mean, "averaged" it out for you) with a deviation of .7 gallons ("give or take" .7 gallons).  On any given day (throw these words out) 68% of the cows (don't need this information to answer the question either, thrown in to confuse you) will produce an amount of milk within which of the following ranges?  Just subtract the deviation ("give or take number") .7 gallons from the mean (average (already determined)) 6.2 gallons which is 5.5 gallons THEN add the deviation ("give or take number") .7 gallons to the mean (average (already determined)) 6.2 gallons which is 6.9 gallons.  Your answer is A 5.5 gallons to 6.9 gallons.     You don't even have to go crazy on the math on this question you can rule them all out but A immediately with subtracting .7 from 6.2.  Mind games .... LOL sneaky.
