4 right triangular pyramids make a cube now instead of a cube suppose there's a square prism
4 times volume of triangular pyramids should be equal to the volume of square prism
(4bh)/3 = a^2 * h
but since its a square at the base, let us suppose that 2ar(triangle at base) = area of square
(2*a^2h)/3=a^2 * h
which gives 2/3=1
which should mean that a cube is not made of 4 pyramids
but we know that is not true
how?

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5

ur right ive taken the test

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.

38 was the other number of your question.
