400/1600 =25%
Explanation:
Total=1,200+400=1,600
Answer:
(4x - 6)(y + 1)
Step-by-step explanation:
Group them: (4xy + 4x) (-6y - 6)
Take out the greatest common factor for both:
4x(y + 1) -6(y + 1)
Put it together: (4x - 6) (y + 1) (y + 1)
Since there are two (y + 1)'s, you can get rid of one, giving you:
(4x - 6) (y + 1)
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
