Answer: √72 or 8.49 units when rounded to the nearest hundredth.


Explanation: Because we have the endpoints if a segment and want to find the length of the entire segment, we need the distance formula.

Its general equation is √(x2-x1)+(y2-y1)

Substituting gives us √(-1-5)^2+(-9-(-3)^2


Simplifying gives us √36+36 which is √72

Also this is just a simple thing that some people forget: When you have parentheses, the exponent is distributed to everything inside including the negative. This is why we did not have a negative answer like -36 after simplifying.

Answer:

36 parts water

Step-by-step explanation:

3/9 = 1/3 = for every 1 part concrete, it's 3 parts water.

12/x = 1/3; x = 36

Which expression is the factored form of −1.5w+7.5 ?
tresset_1 [31]
The correct answer is C) -1.5(w-5).

Both numbers are divisible by 1.5.  Since there is a negative in the first term, we will factor that out as well.  This means we are dividing both terms by -1.5:

-1.5(     )

Taking -1.5 out of -1.5w, we have w left:

-1.5(w    )

Dividing 7.5 by -1.5, we have -5:

-1.5(w-5)
