Rocky ate 42 cups of dog food. Since there are 7 days in a week, 21 cups were eaten per week (3x7). Since the question is asking for the amount in two weeks, you multiply 21x2 to get 42.

Answer:

42 cups of dog food.

Step-by-step explanation:

Rocky ate 3 cups of dog food each day for two weeks, there's 7 days in a week, if you multiply 14 ( number of days in 2 weeks) and 3( the number of dog food each day) you would get 42 because 7 days are in 1 weeks and if you add another 7 days, you would get 14 days and by multiplying that by 3, the dog food Rocky ate each day, you would get 42, the answer to your question. Hope this answers your question!

Simplify the radical expression.. square root of 128
Vaselesa [24]
Hello,

first we have to descompose the number:

128  | 2
  64  | 2
  32  | 2
  16  | 2
    8  | 2
    4  | 2
    2  | 2
    1

So: 
128= 2x2x2x2x2x2x2 \\ 128=2^{6} *2

Therefore:
\sqrt{128}= \sqrt{2^{6} *2}

You must know these properties:

\sqrt{a*b} = \sqrt{a} * \sqrt{b}\\ \\ \sqrt[b]{x^a}= x^{ \frac{a}{b}}

then:

\sqrt{2^{6} *2} \\ =\sqrt{2^{6}}*\sqrt{2} \\ =2^{ \frac{6}{2}}*\sqrt{2} \\ =2^3*\sqrt{2} \\ \boxed{=8*\sqrt{2}}

Can somebody help me please
Drupady [299]

Answer:

y=-5/2x+(Any number)

Step-by-step explanation:

First, find the slope of that line

3+2=5

-5+7=2

5/2 is the slope

Perpendicular lines have the slope that is opposite and a fliped sign

This means that the slope should be -2/5

The equation of the line would be y=-5/2x+(Any number)
