Dovator [93]

The height of the green pyramid constructed  by Natalie while playing with magnetic building tiles is 26.25 cm.

<h3>Volume of the orange pyramid</h3>

The volume of the orange pyramid is calculated as follows;

V = ¹/₃Ah

where;

  • A is the base area of the pyramid
  • h is the height of the pyramid

V = ¹/₃ x (7²) x 5

V  = ¹/₃ x (245 cm³)

<h3>Volume of the green pyramid</h3>

Voume = 21 x [¹/₃ x (245 cm³)]

Volume = 1,715 cm³

<h3>Height of the green pyramid</h3>

V = ¹/₃Ah

3V = Ah

h = 3V/A

h = (3 x 1715) / (14²)

h = 26.25 cm

qwelly [4]

Given :

An online store sells only two types of bandanas: cotton bandanas and silk bandanas. Cotton bandanas cost $7 each, and silk bandanas cost $11 each.

Mrs. Tran spent a total of $93 on bandanas at this store.

To Find :

How many cotton bandanas did Mrs. Tran buy.

Solution :

Let, number of cotton and silk bandanas buys are x and y respectively.

So, 7x + 11y = 93

x = (93 - 11y)/ 7

Putting y = 1 , x = 82/7 ( not possible since x can only be positive integer )

Putting y = 4 , x = 7

Therefore, Mrs . Tran will buy 7 cotton bandanas.

Hence, this is the required solution.
