△MNO maps to △RST with the transformation (x, y) longrightarrow ( 1 3 x, 1 3 y). Choose True or False for each statement. A. If RT = 3, MO = 9. A True B False B. If RT = 12, MO = 4. A True B False C. If RT = 9, MO = 27. A True B False

Answers

Answer:

The answer is below

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Dilation is the enlargement or reduction in size of a figure. If a figure with point A(x, y) is dilated by a scale factor k, the new point is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.

Since ΔMNO maps to ΔRST with a transformation (x, y) = (3x, 3y), this means that ΔRST is three times the size of ΔMNO, hence all the sides of ΔRST are three times that of ΔMNO.

A. If RT = 3, MO = 9. A True B False B.

This is false because RT = 3 * MO = 3(9) = 27

B. If RT = 12, MO = 4. A True B False

This is true because RT = 3 * MO = 3(4) = 12

C. If RT = 9, MO = 27. A True B False

This is false because RT = 3 * MO = 3(27) = 81

why can you NOT divide by zero? explain and write paragraph HELP ASAP PLEASE

Answers

In ordinary arithmetic, the expression has no meaning, as there is no number which, when multiplied by 0, gives a (assuming a ≠ 0), and so division by zero is undefined. Since any number multiplied by zero is zero, the expression 00 is also undefined; when it is the form of a limit, it is an indeterminate form.

Answer:

you cant divide by nothing. zero has no value so be dividing by nothing. also your outcome would be nothing. hope this helps

Pyramid A has a quadrilateral base, a height of 4 units, and a volume of 20 cubic units. Pyramid B has the same base area, but its height is 12 units.

Answers

Answer:

60 cubic units

Step-by-step explanation:

i got it correct on khan. all credit goes to ddynely. thank you.

The volume of Pyramid B will be 60 cubic unit.

Pyramid In geometry, a pyramid is a formed by connecting a polygonal base and a point

How to solve this problem?

The steps are as follow:

Height of Pyramid A and Pyramid B are given which is as hₐ = 4 units and hₓ = 12 units respectivelySₐ and Sₓ are base of Pyramid A and Pyramid B respectively which are equal i.e Sₐ = SₓVolume of pyramid is given by 1/3(Sh); S = base of pyramid and h = height of pyramidGiven

hₐ = 4 units

hₓ = 12 units = 3hₐ

Sₐ = Sₓ

Volume of pyramid A = 1/3(Sₐhₐ) = 20 cubic units

Volume of pyramid B = 1/3(Sₓhₓ) = 1/3(Sₐ*3hₐ) = 3*Vₐ = 3*20 = 60cubic units

So the volume of Pyramid B will be 60 cubic unit.
