Mr. Jackson has an empty pyramid and an empty prism. The base of the pyramid is congruent to the base of the prism, and their heights are equal. Determine the number of times Mr. Jackson must fill the pyramid with water and pour it into the prism in order to completely fill the prism with water.

Answers

Answer:
Volume of water required to fill the pyramid is rd of the water required to fill the prism completely.
Step-by-step explanation:
Let Mr Jackson has an empty rectangular pyramid and rectangular prism.
Height and base of both are congruent.
So volume of rectangular pyramid

Volume of the rectangular prism = (Area of the base)(height)

[ Since ]


Therefore, amount of water required to fill the pyramid is rd of the water required to fill the prism completely.

Which of the following is true about a parallelogram?
The diagonals are equal.
All sides are congruent.
The diagonals bisect each other.
The diagonals are perpendicular.

Answers

Answer:

The diagonals bisect each other.

Step-by-step explanation:

Not all diagonals of a parallelogram are equal.

The only quadrilaterals with all four sides being congruent are rhombus and squares so parallelogram is wrong.

The diagonals of a parallelogram bisect each other.

The diagonals of a parallelogram are only perpendicular when it is a square.

Y is inversely proportional to x, when Y = 7, x = 4.
True or False: the constant of proportionality, k, is 20.

Answers

Answer:

The given statement  Y = 7, x = 4 is False.

Step-by-step explanation:

We are given:

Y is inversely proportional to x, when Y = 7, x = 4.

We need to tell if the statement is True or False: the constant of proportionality, k, is 20.

Y is inversely proportional to x

We can write it as: [tex]y\:\alpha \:\frac{1}{x}\\y=\frac{k}{x}[/tex]

Now, we need to check when Y=7, x = 4 is true or false

We are given k = 20

Now, I can find value of y, by putting values of k and x in the equation:

[tex]y=\frac{k}{x}\\y=\frac{20}{4}\\y=5[/tex]

When we put x = 4, and k =20, we get Y=5 and not Y=7

So, The given statement  Y = 7, x = 4 is False.

A home-decorating company is determining the amount of fabric required for a customer's window treatments. A single window requires 11 2/3 yards and a double window requires 15 5/6
yards of fabric. If there are two single windows and one double window, how much fabric is required?

Answers

Answer:

[tex]2S + D = 34\frac{1}{6}\ yd[/tex]

Step-by-step explanation:

Represent single windows with S and double with D.

So, we have:

[tex]S = 11\frac{2}{3}\ yd[/tex]

[tex]D = 15\frac{5}{6}\ yd[/tex]

Required

Determine the amount of fabric for 2 singles and 1 double

The above statement implies:

[tex]2S + D[/tex]

Substitute values for S and D

[tex]2S + D = 2 * 11\frac{2}{3}\ yd + 15\frac{5}{6}\ yd[/tex]

Convert fractions

[tex]2S + D = 2 * \frac{35}{3}\ yd + \frac{65}{6}\ yd[/tex]

[tex]2S + D = \frac{70}{3}\ yd + \frac{65}{6}\ yd[/tex]

Tale LCM

[tex]2S + D = \frac{140+65}{6}\ yd[/tex]

[tex]2S + D = \frac{205}{6}\ yd[/tex]

[tex]2S + D = 34\frac{1}{6}\ yd[/tex]

Hence, [tex]34\frac{1}{6}\ yd[/tex] is needed
