Answer: The diagonals of a parallelogram bisect each other. Steps (a), (b), and (c) outline proof of this theorem. (See Exercise 25 for a particular instance of this theorem.) (a) In the parallelogram OA BC shown in the figure, check that the coordinates of must be (b) Use the midpoint formula to calculate the midpoints of diagonals and (c) The two answers in part (b) are identical. This shows that the two diagonals do indeed bisect each other, as we wished to prove. (FIGURE CAN'T COPY)

Given the following information, choose the brand that is the better buy. Brand A: $2. 16 for 18 ounces Brand B: $1. 50 for 12 o

topjm [15]

Using the division rule, the better buy is that Brand C gives 8.85 ounces for $1. Then the Brand C is better than Brand A, Brand B, and Brand D.

<h3>What is division?</h3>

The division means the separation of something into different parts, sharing of something among different people, places, etc.

Given

The brand that is the better buy.

1. Brand A: $2.16 for 18 ounces

So in $1, the ounces will be

$\rm Brand\ A = \dfrac{18}{2.16}\\\\Brand \ A = 8.33$

Brand A gives 8.33 ounces for $1.

2. Brand B: $1.50 for 12 ounces

So in $1, the ounces will be

$\rm Brand\ B = \dfrac{12}{1.5}\\\\Brand \ B= 8$

Brand B gives 8 ounces for $1.

3. Brand C: $2.26 for 20ounces

So in $1, the ounces will be

$\rm Brand\ C= \dfrac{20}{2.26}\\\\Brand \ C= 8.85$

Brand C gives 8.85 ounces for $1.

4. Brand D: $1.95 for 16 ounces

So in $1, the ounces will be

$\rm Brand\ D= \dfrac{16}{1.95}\\\\Brand \ D= 8.21$

Brand D gives 8.21 ounces for $1.

Thus, Brand C gives 8.85 ounces for $1.

A line has the points (2,4) and (7, 8). Which equation is parallel to this line?

agasfer [191]

Answer: The answer should be A.

Step-by-step explanation: Remember the formula for slope, m= $\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$ , using the coordinates you will find that the slope of this line is 4/5. Now we know that parallel lines always have the same slope with different y-intercepts or b values. Therefore, A is your answer.
