Which is the net of this solid? A pentagonal pyramid is shown. A net is shown with a square in the middle and 4 identical triang

Neko [114]

Answer: Choice B

A net is shown with a pentagon in the middle and 5 identical triangles on the 5 sides of the pentagon

The pentagon forms the base of the pentagonal pyramid. Each lateral side is a triangle that meets at the very top of the pyramid. The base stays on the floor while the sides are folded up.

---------------------------

There are other possible net configurations to form a pentagonal pyramid, but the other answer choices do not make a pentagonal pyramid.

Choice A produces a square pyramid.
Choice C makes a triangular pyramid (aka tetrahedron).
Choice D makes a hexagonal pyramid.

So we can rule choices A, C and D out.

Read the following description of a

Annette [7]

Answer:

$\sf a = \boxed{\bf 1} \ n+ \boxed{\bf 3}$

Explanation:

$\sf \underline{rate} \ = \ \sf \dfrac{y_2-y_1}{x_2-x_1} \ = \ \dfrac{rise}{run} \ = \ \dfrac{11-10}{8-7} \ = \ \underline{1}$

Equation:

$\Rightarrow \sf a - a1 = m(n - n1)$

$\Rightarrow \sf a - 10 = 1(n -7)$

$\Rightarrow \sf a = n - 7 + 10$

$\Rightarrow \sf a = n + 3$

11) the difference between the product of 4 and a number and the square of the number

marta [7]

Answer:

$= 4x-x^2\\\\$

Step-by-step explanation:

Let the number be x;

The product of 4 and the number will be;

$= 4 * x\\\\= 4x$

The the square of the number is given as;

$= x^2\\$

Taking the difference of both expressions above;

$= 4x-x^2\\\\$

Factor out the common term:

$= x(4-x)\\\\$

Hence the difference between the product of 4 and a number and the square of the number is $= 4x-x^2\\\\$

A solid right pyramid has a square base with an edge length of x cm and a height of y cm. Which expression represents the volume

solniwko [45]

Answer:

Thus, volume of pyramid = $\frac{1}{3}x^2y$ cm³

Step-by-step explanation:

Given: A solid right pyramid has a square base with an edge length of x cm and a height of y cm.

We have to choose from the given options an expression for the volume of the pyramid.

Volume of pyramid = $\frac{1}{3}\times Area\ of\ base \times height$

Since base is a square with edge length x cm.

Area of square = (side)² = x²

Thus, volume of pyramid = $\frac{1}{3}x^2y$ cm³
