2. Sammie has 3 feet of ribbon. She is making bows for her friends that each use of 1/3 of a foot

lilavasa [31]

Answer:

Sammy can make 9 bows.

Step-by-step explanation:

3 feet of Ribbon

1/3 for each bow

1/3 + 1/3 +1/3 = 3/3 or 1 so she can make 3 bows out of one foot of ribbon

so if you repeat this than you should get 9 bows out of three feet of ribbion.

(x + y + 2)(y + 1)<br> Solve

RideAnS [48]

Hello there! We are given the following equation and want to simplify it:

$(x+y+2)(y+1)$

First, let's use the Distributive Property:

$(a+b)(c)=ac+bc$

For this step, we are going to let:

$a=y$

$b=1$

$c=(x+y+2)$

After applying this version of the Distributive Property, we are given the equation:

$(y)(x+y+2)+(1)(x+y+2)$

We're going to use the distributive party again, but a slightly different version that's almost the same as first:

$(a)(b+c+d)=ab+ac+ad$

Using this on both terms of the equation changes the equation to:

$(xy+y^2+2y)+(x+y+2)$

Now, we just remove the parenthesis and combine like terms

$y^2+3y+xy+x+2$

This should be your answer. Let me know if you need any clarifications, thanks!

use the plot of the concentration of cu(no3)3 versus absorbance provided. if the absorbance of an unknown was determined to be 0

Helen [10]

Using the linear regression equation, the concentration of the unknown solution is 0.2161 M.

Linear regression describes the relationship of two variables. It may not be exact but it is the line that best fit the data. The equation for a linear regression is in the form y = bx + a, where x and y are the two variables.

If the absorbance of an unknown was determined to be 0.67 absorbance units, using the linear regression equation provided from the plot, substitute the value of absorbance to the variable y and solve for the value of x or the concentration.

y = 3.8674x - 0.1657

0.67 = 3.8674x - 0.1657

3.8674x = 0.67 + 0.1657

3.8674x = 0.8357

x = 0.2161

Hence, the concentration is 0.2161 M.
