Answer:

(D)Prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals

Step-by-step explanation:

To use coordinate geometry to prove that quadrilateral ABCD is a rectangle. We prove that opposite sides are congruent in order to show equality of the lines.

We also show that the slopes of consecutive sides are opposite reciprocals, this is in order to show that the lines are perpendicular to one another.

The correct option is D.

Answer:

80 gummy bears are in 4 servings.

Step-by-step explanation:

2 servings=40 gummy bears

3 servings=60 gummy bears

40+20=60

Add 20 gummy bears for every serving.

5 servings=100 gummy bears

100-20=80 gummy bears are in 4 servings

OR you can also do:

40÷2=20 gummy bears are in each serving

So, 4x20=80 gummy bears are in 4 servings

sergiy2304 [10]

Answer:

Approximately $238\ gallons$

Step-by-step explanation:

we know that

The volume of a cylinder (barrel) is equal to

$V=\pi r^{2}h$

in this problem we have

$h=4.5\ ft$

$r=3/2=1.5\ ft$ -----> the radius is half the diameter

substitute

$V=(3.14)(1.5^{2})(4.5)=31.7925\ ft^{3}$

Convert to gallons

$31.7925\ ft^{3}*7.5=238.44\ gallons$

On Gavin's math test, 3/8 of the questions are division problems. Of the division problems, 4/9 of the problems he got incorrect

deff fn [24]

Something is strange in the wording of the question. "Of the division problems, 4/9 of the problems he got incorrect. What fraction of the division problems did Gavin get incorrect?" :) Well 4/9 of course. One statement answers another. Maybe they wanted the fraction of those wrong answers were in relation to the entire test???

$\frac {3}{8} * \frac {4}{9} = \frac {12}{72} = \frac {1}{6}$
