Answer:

35 cubic inches

Step-by-step explanation:

The volume of a pyramid is \frac{1}{3} bh, where b = base and h = height. To find the area of the base, we multiply 3 by 5 and then divided by 2.

  • 3 × 5 = 15
  • 15 ÷ 2 = 7.5

Next, we multiply 7.5 by 14.

  • 7.5 × 14
  • 105

Lastly, we divide by 3.

  • 105 ÷ 3
  • 35

Therefore, the answer is 35 cubic inches.

Layana’s house is located at (2 and two-thirds, 7 and one-third) on a map. The store where she works is located at (–1 and one-t
Arturiano [62]

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.
