the distance from Layana’s home to the store is 4 units .

<u>Step-by-step explanation:</u>

We know that distance between two points P(x_1,y_1),Q(x_2,y_2) is given by :

⇒ D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

According to question we have ,

P(x_1,y_1 )= (2\frac{2}{3}, 7\frac{1}{3}) = (\frac{8}{3},\frac{22}{3})\\Q(x_2,y_2) =( -1\frac{1}{3}, 7\frac{1}{3}) = ( -\frac{4}{3}, \frac{22}{3})

Putting these values in above equation we get :

⇒ D = \sqrt{(-\frac{4}{3}-\frac{8}{3})^2+(\frac{22}{3}-\frac{22}{3})^2}

⇒ D = \sqrt{(-\frac{12}{3})^2}

⇒ D =\frac{12}{3}

⇒ D =4

Therefore , the distance from Layana’s home to the store is 4 units .

The distance between Layana's house and store is 4 units.

<u>Explanation:</u>

Given:

Coordinates of Layana's house = (2\frac{2}{3} , 7\frac{1}{3})

Coordinates of the store = (-1\frac{1}{3}, 7\frac{1}{3})

It can also be written as:

Coordinates of Layana's house = (\frac{8}{3}  , \frac{22}{3})

Coordinates of the store = (-\frac{4}{3}, \frac{22}{3})

The distance between the house and the shop is:

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}

On substituting the value we get:

d = \sqrt{(\frac{-4 - 8}{3} )^2 + (\frac{22-22}{3} )^2} \\\\d = \sqrt{\frac{144}{9} } \\\\d = \frac{12}{3} \\\\d = 4 units

Therefore, the distance between Layana's house and store is 4 units.

Answer:

Volume of a cup

The shape of the cup is a cylinder. The volume of a cylinder is:

\text{Volume of a cylinder}=\pi \times (radius)^2\times heightVolume of a cylinder=π×(radius)

2

×height

The diameter fo the cup is half the diameter: 2in/2 = 1in.

Substitute radius = 1 in, and height = 4 in in the formula for the volume of a cylinder:

\text{Volume of the cup}=\pi \times (1in)^2\times 4in\approx 12.57in^3Volume of the cup=π×(1in)

2

×4in≈12.57in

3

2. Volume of the sink:

The volume of the sink is 1072in³ (note the units is in³ and not in).

3. Divide the volume of the sink by the volume of the cup.

This gives the number of cups that contain a volume equal to the volume of the sink:

\dfrac{1072in^3}{12.57in^3}=85.3cups\approx 85cups

12.57in
